Saving user's selection when refreshing the page - javascript

I currently have a page that displays data for different teams.
I have some data that the user can click on to make it an "on" or "off" state, showing a different icon for each. It's basically like a checklist, just without the physical checkboxes.
I would like to remember which of the "checkboxes" have been ticked, even after the user refreshes the page or closes the browser and returns later.
I have heard that localStorage is a good option, but I'm not sure how to use it in a situation like mine.
Currently I have this code:
team1 = {
"information1": {
"name": "tom",
"age": "34"
},
"information2": {
"name": "bob",
"age": "20"
},
};
team2 = {
"information1": {
"name": "betsy",
"age": "27"
},
"information2": {
"name": "brian",
"age": "10"
},
};
$(document).ready(function() {
$("#displayObject1").on("click", function() {
switchData(team1);
});
$("#displayObject2").on("click", function() {
switchData(team2);
});
$("#table").on("click", ".on", function() {
$(this).removeClass("on");
$(this).addClass("off");
});
$("#table").on("click", ".off", function() {
$(this).addClass("on");
$(this).removeClass("off");
});
});
function switchData(object) {
$("#table").contents("div").remove();
if (!('rows' in object)) {
var rows = [];
Object.keys(object).forEach(function (key) {
if (key != 'rows') {
rows.push($('<div class="row on">' + object[key].name + '</div>'));
}
});
object.rows = rows;
}
object.rows.forEach(function (row) {
$('#table').append(row);
});
}
This makes rows to represent a team. The rows are retained with their color highlighting when the user looks at different teams during a browser session.
This is my HTML:
<div id="displayObject1">
<span>Display object 1</span>
</div>
<div><hr></div>
<div id="displayObject2">
<span>Display object 2</span>
</div>
<div id="table">
</div>
And some CSS to show which list items are "on" and "off".
.on {
background-color: green;
}
.off {
background-color: red;
}
How can the page remember the color highlighting?

If you want to use local storage to make the state of the team listings persist across browser sessions, you have to maintain a logical representation of the state and save it as a string whenever the state changes.
JSON.stringify lets you encode a JavaScript object in a JSON string. For example, you can call a function like the following whenever you modify a global object named pageState:
function savePageState() {
localStorage.setItem('pageState', JSON.stringify(pageState));
}
To retrieve the page state on page load, you can do something like this:
pageState = JSON.parse(localStorage.getItem('pageState'));
if (pageState === null) {
pageState = {
teams: teams
};
savePageState();
} else {
teams = pageState.teams;
}
If pageState wasn't saved in a previous session, it is now created and saved to local storage. Otherwise, we consult pageState for data that we can use to restore the previous appearance of the team listings.
This code sample works on the assumption that the global object teams contains information relevant to the page state. You can add further properties to the page-state object to store more information. For example, to remember which team is currently displayed, you could do:
pageState.showTeam = teamName;
Then you can consult pageState.showTeam when you're initializing the page contents, perhaps like this:
if (teamName == pageState.showTeam) {
showTeam(teamName);
$(label).addClass('selected');
}
I have made a page that demonstrates this approach. I can't include it in my answer as a snippet because localStorage is sandboxed, but you can access the page here:
http://michaellaszlo.com/so/click-rows/
I've reorganized your team data to enable dynamic page initialization. Now each team object contains an array of person objects.
When the user clicks on a team member's name, the CSS class selected is toggled on the HTML element and the corresponding person object is updated by toggling its selected property:
function memberClick() {
$(this).toggleClass('selected');
this.person.selected = (this.person.selected ? false : true);
savePageState();
};
The showTeam function checks a person's selected property when it's building its HTML representation, and adds the CSS class selected if appropriate. This is what makes it possible to restore the visual appearance of the page from the last session.

you can set a flag in localStorage for each option using:
localStorage.setItem('item1',true) //set the value to the checkbox's value
and access it using:
flagValue = localStorage.item1
use these values similarly in your code once the document is ready to set the initial values of the checkboxes accordingly

Store click value to use later on

Basically, I have an appointment form which is broken down into panels.
Step 1 - if a user clicks london (#Store1) then hide Sunday and Monday from the calendar in panel 5.
Basically, I want to store this click so that when the user gets to the calendar panel, it will know not to show Sunday and Monday
$('#store1').click(function () {
var $store1 = $(this).data('clicked', true);
console.log("store 1 clicked");
$('.Sunday').hide();
$('.Monday').hide();
});
after I have captured this in a var I then want to run it when the calendar displays.
function ReloadPanel(panel) {
return new Promise(function (resolve, reject, Store1) {
console.log(panel);
console.log("finalpanel");
panel.nextAll('.panel').find('.panel-updater').empty();
panel.nextAll('.panel').find('.panel-title').addClass('collapsed');
panel.nextAll('.panel').find('.panel-collapse').removeClass('in');
var panelUpdater = $('.panel-updater:eq(0)', panel),
panelUrl = panelUpdater.data('url');
if (panelUpdater.length) {
var formData = panelUpdater.parents("form").serializeObject();
panelUpdater.addClass('panel-updater--loading');
panelUpdater.load(panelUrl, formData, function (response, status) {
panelUpdater.removeClass('panel-updater--loading');
if (status == "error") {
reject("Panel reload failed");
} else {
resolve("Panel reloaded");
}
});
} else {
resolve("no reloader");
}
});
}
I'm not sure if this is even written right, so any help or suggestions would be great
Thanks in advance
Don't think of it as "storing a click". Instead, consider your clickable elements as having some sort of data values and you store the selected value. From this value you can derive changes to the UI.
For example, consider some clickable elements with values:
<button type="button" class="store-button" data-store-id="1">London</button>
<button type="button" class="store-button" data-store-id="2">Paris</button>
<button type="button" class="store-button" data-store-id="3">Madrid</button>
You have multiple "store" buttons. Rather than bind a click event to each individually and customize the UI for each click event, create a single generic one which captures the clicked value. Something like:
let selectedStore = -1;
$('.store-button').on('click', function () {
selectedStore = $(this).data('store-id');
});
Now anywhere that you can access the selectedStore variable can know the currently selected store. Presumably you have some data structure which can then be used to determine what "days" to show/hide? For example, suppose you have a list of "stores" each with valid "days":
let stores = [
{ id: 1, name: 'London', days: [2,3,4,5,6] },
// etc.
];
And your "days" buttons have their corresponding day ID values:
<button type="button" class="day-button" data-day-id="1">Sunday</button>
<button type="button" class="day-button" data-day-id="2">Monday</button>
<!--- etc. --->
You can now use the data you have to derive which buttons to show/hide. Perhaps something like this:
$('.day-button').hide();
for (let i in stores) {
if (stores[i].id === selectedStore) {
for (let j in stores[i].days) {
$('.day-button[data-day-id="' + stores[i].days[j] + '"]').show();
}
break;
}
}
There are a variety of ways to do it, much of which may depend on the overall structure and flow of your UX. If you need to persist the data across multiple pages (your use of the word "panels" implies more of a single-page setup, but that may not necessarily be the case) then you can also use local storage to persist things like selectedStore between page contexts.
But ultimately it just comes down to structuring your data, associating your UI elements with that data, and performing logic based on that data to manipulate those UI elements. Basically, instead of manipulating UI elements based only on UI interactions, you should update your data (even if it's just in-memory variables) based on UI interactions and then update your UI based on your data.
you can use the local storage for that and then you can get your value from anywhere.
Set your value
localStorage.setItem("store1", JSON.stringify(true))
Get you value then you can use it anywhere:
JSON.parse(localStorage.getItem("store1"))
Example:
$('#store1').click(function() {
var $store1 = $(this).data('clicked', true);
localStorage.setItem("store1", JSON.stringify(true))
console.log("store 1 clicked");
$('.Sunday').hide();
$('.Monday').hide();
});

How to reflect change made in a component's variable to the view in Angular 2?

I have (n) check boxes and a button in my angular2 view . When I click on one of them a function is called. When I click on the button every checkbox must be unchecked. How to do it?? (n) may vary dynamically.
enter image description here
I will give you an example from a table, since I have no idea what your code actually looks like, but it should work for what you need.
You need some object defined for all of your checkboxes. They likely all have certain properties in common, like labels. Here is an example of such an object:
myData = {
content: [
{
some_string: '',
some_number: 0,
type: '',
selected: false
}
]
};
With this object you can create checkbox instances and push each one to an array, which will hold all of your checkbox objects.
Create your checkboxes in your html in a loop using the objects you have defined above. In your html have your checkboxes call a function. In the case below the checkToggle() function is called.
<input id='{{row.id}}' class='bx--checkbox bx--checkbox--svg'
type='checkbox' name='checkbox' (change)="checkToggle($event,
row.id)" [checked]="row.selected">
checkToggle() has been defined as follows:
//select or deselect this check box
checkToggle(event, nodeId) {
const id = this.findNode(nodeId);
this.myData.content[id].selected = !this.myData[id].selected;
}
Your button should end up calling a function to check all of the boxes
<button (click)="checkToggleAll($event)">Your Button Title</button>
Finally, have your checkToggleAll() function go through the entire array of checkboxes and set them. Here is an example:
//select or deselect all the check boxes
checkToggleAll(event) {
for (let i = 0; i < this.myData.content.length; i++) {
if (this.controls[this.myData.content[i].type]) {
this.myData.content[i].selected = event.target.checked;
}
}
}
This is not something you can plug into your code but it should give you some idea of how to accomplish what you're after.

How do I detect the first time the user logs in and the first time a specific page is loaded?

I would like to Trigger some JS only the first time a user logs in, and only the first time a specific page is loaded.
I believe I can deal with the first time they log in, by simply checking user.sign_in_count < 2, but I don't know how to specify just on the first page load only.
i.e. I don't want the JS to be triggered after the user logs in for the first time and refreshes the page without logging out.
I am using Turbolinks and $(document).on('turbolinks:load', function() { to trigger it.
Edit 1
So what I am trying to do is execute Bootstrap Tour on a number of pages. But I only want that tour to be automatically executed, on the first page load. The tour itself will lead the user to other specific pages within my app, but each of those pages will have page-specific tour JS on each page.
Right now, in my HTML I have something like this:
<script type="text/javascript">
$(document).on('turbolinks:load', function() {
var tour = new Tour({
storage: false,
backdrop: true,
onStart: function(){
$('body').addClass('is-touring');
},
onEnd: function(){
$('body').removeClass('is-touring');
},
steps: [
{
element: "#navbar-logo",
title: "Go Home",
content: "All throughout the app, you can click our logo to get back to the main page."
},
{
element: "input#top-search",
title: "Search",
content: "Here you can search for players by their name, school, positions & bib color (that they wore in our tournament)"
}
]});
// Initialize the tour
tour.init();
// Start the tour
tour.start();
});
</script>
So all I really want to do is the following:
Not bombard the user with executing a new tour, on their first login, whenever they reload the page.
Allow them to be able to manually execute the tour at a later date if they want, by simple pressing a link.
I don't want to store anything in my DB if I don't have to -- so preferably this should be a cookie-based approach or localStorage
Assume that I will use Rails to track the number of sign-ins they have done. So once they sign in more than once, I can not trigger this JS.
The real problem is just within that first sign in, if they refresh the main page 10 times, this tour gets executed 10 times. That's what I am trying to stop.
I hope that provides some more clarity.
Preface
It's my understanding that you have:
multiple pages that contain a single tour (each page's tour is different)
a way to detect first signin to an account (ruby login count)
ability to add a script value based upon first signin
Solution Overview
The solution below uses localStorage to store a key value pair of each tour's identifier and if it has been seen or not. localStorage persists between page refreshes and sessions, as the name suggests, localStorage is unique to each domain, device, and browser (ie. chrome's localStorage cannot access firefox's localStorage even for the same domain, nor can chrome's localStorage on your laptop access chrome's localStorage on your mobile even for the same domain). I raise this to illustrate the reliance upon Preface 3 to toggle a JS flag for if the user has logged in previously.
For the tour to start, the code checks localStorage for if its corresponding key value pair is not set to true (representing having been "seen"). If it does exist and is set to true, the tour does not start, otherwise it runs. When each tour begins, using its onStart method, we update/add the tour's identifier to localStorage and set its value to true.
Manual execution of the tour can be performed by either manually calling the tour's start method if you would like only the current page's tour to execute, otherwise, you can clear out all of the localStorage related to the tour and send the user back to the first page/if you're on the first page, again just call the start method.
JSFiddle (HTML based off other question's you've asked regarding touring)
HTML (this could be any element with the id="tourAgain" attribute for the following code to work.
<button class="btn btn-sm btn-default" id="tourAgain">Take Tour Again</button>
JS
var isFirstLogin = true; // this value is populated by ruby based upon first login
var userID = 12345; // this value is populated by ruby based upon current_user.id, change this value to reset localStorage if isFirstLogin is true
// jquery on ready function
$(function() {
var $els = {}; // storage for our jQuery elements
var tour; // variable that will become our tour
var tourLocalStorage = JSON.parse(localStorage.getItem('myTour')) || {};
function activate(){
populateEls();
setupTour();
$els.tourAgain.on('click', tourAgain);
// only check check if we should start the tour if this is the first time we've logged in
if(isFirstLogin){
// if we have a stored userID and its different from the one passed to us from ruby
if(typeof tourLocalStorage.userID !== "undefined" && tourLocalStorage.userID !== userID){
// reset the localStorage
localStorage.removeItem('myTour');
tourLocalStorage = {};
}else if(typeof tourLocalStorage.userID === "undefined"){ // if we dont have a userID set, set it and save it to localStorage
tourLocalStorage.userID = userID;
localStorage.setItem('myTour', JSON.stringify(tourLocalStorage));
}
checkShouldStartTour();
}
}
// helper function that creates a cache of our jQuery elements for faster lookup and less DOM traversal
function populateEls(){
$els.body = $('body');
$els.document = $(document);
$els.tourAgain = $('#tourAgain');
}
// creates and initialises a new tour
function setupTour(){
tour = new Tour({
name: 'homepage', // unique identifier for each tour (used as key in localStorage)
storage: false,
backdrop: true,
onStart: function() {
tourHasBeenSeen(this.name);
$els.body.addClass('is-touring');
},
onEnd: function() {
console.log('ending tour');
$els.body.removeClass('is-touring');
},
steps: [{
element: "div.navbar-header img.navbar-brand",
title: "Go Home",
content: "Go home to the main page."
}, {
element: "div.navbar-header input#top-search",
title: "Search",
content: "Here you can search for players by their name, school, positions & bib color (that they wore in our tournament)"
}, {
element: "span.num-players",
title: "Number of Players",
content: "This is the number of players that are in our database for this Tournament"
}, {
element: '#page-wrapper div.contact-box.profile-24',
title: "Player Info",
content: "Here we have a quick snapshot of the player stats"
}]
});
// Initialize the tour
tour.init();
}
// function that checks if the current tour has already been taken, and starts it if not
function checkShouldStartTour(){
var tourName = tour._options.name;
if(typeof tourLocalStorage[tourName] !== "undefined" && tourLocalStorage[tourName] === true){
// if we have detected that the tour has already been taken, short circuit
console.log('tour detected as having started previously');
return;
}else{
console.log('tour starting');
tour.start();
}
}
// updates localStorage with the current tour's name to have a true value
function tourHasBeenSeen(key){
tourLocalStorage[key] = true;
localStorage.setItem('myTour', JSON.stringify(tourLocalStorage));
}
function tourAgain(){
// if you want to tour multiple pages again, clear our localStorage
localStorage.removeItem('myTour');
// and if this is the first part of the tour, just continue below otherwise, send the user to the first page instead of using the function below
// if you just want to tour this page again just do the following line
tour.start();
}
activate();
});
PS. the reason we dont use onEnd to trigger the tourHasBeenSeen function is that there is currently a bug with bootstrap tour where if the last step's element doesnt exist, the tour ends without triggering the onEnd callback, BUG.
You could try using Javascript's sessionStorage, which is deleted when the user closes the tab, but survives through refreshes. Just use sessionStorage.setItem(key, value and sessionStorage.getItem(key). Remember that sessionStorage can only store strings!
Using your code:
<script type="text/javascript">
$(document).on('turbolinks:load', function() {
var tour = new Tour({
storage: false,
backdrop: true,
onStart: function(){
$('body').addClass('is-touring');
},
onEnd: function(){
$('body').removeClass('is-touring');
},
steps: [
{
element: "#navbar-logo",
title: "Go Home",
content: "All throughout the app, you can click our logo to get back to the main page."
},
{
element: "input#top-search",
title: "Search",
content: "Here you can search for players by their name, school, positions & bib color (that they wore in our tournament)"
}
]});
if(sessionStorage.getItem("loggedIn") !== "yes"){//Remember that sessionStorage can only store strings!
//Initialize the tour
tour.init();
// Start the tour
tour.start();
}
else{
//Set item "loggedIn" in sessionStorage to "yes"
sessionStorage.putItem("loggedIn", "yes");
}
var goBackToTour = function(e){
//You can also make a "fake" link, so that it looks like a link, but is not, and you don't have to put the following line:
e.preventDefault();
tour.init();
tour.start();
};
document.getElementById("goBackToTourLink").addEventListener("click", goBackToTour);
});
//On the logout
var logout = function(){
sessionStorage.setItem("loggedIn", "no");
};
</script>
You can store if user has seen the tour or not in the cookie. You can maintain a "TrackingCookie" which has all the user tracking information (eg. tour_shown, promotion_shown etc, which is accessed by your javascript
code. Following TrackingCookie code is to maintain all such tracking information in one cookie. I am calling it tracking_cookie.
Cookies can be accessed server-side using
cookies[:tracking_cookie]
tracking_cookie.js
var TrackingCookie = (function() {
function TrackingCookie() {
this.name = 'tracking_cookie';
this.expires = new Date(new Date().setYear(new Date().getFullYear() + 1));
}
TrackingCookie.prototype.set = function(name, value) {
var data={};
if(!this.readFromStore()) {
data = this.readFromStore();
}
data[name] = value;
return this.writeToStore(data);
};
TrackingCookie.prototype.set_if_unset = function(name, value) {
if (!this.get(name)) {
return this.set(name, value);
}
};
TrackingCookie.prototype.get = function(name) {
return this.readFromStore()[name];
};
TrackingCookie.prototype.writeToStore = function(data) {
return $.cookie(this.name, JSON.stringify(data), {
path: '/',
expires: this.expires
});
};
TrackingCookie.prototype.readFromStore = function() {
return $.parseJSON($.cookie(this.name));
};
return TrackingCookie;
})();
In your HTML
<script type="text/javascript">
$(document).on('turbolinks:load', function() {
//Instantiate the cookie
var tracking_cookie = new TrackingCookie();
//Cookie value not set means, it is a new user.
if(!tracking_cookie.get("tour_shown")){
//Set the value to be true.
tracking_cookie.set("tour_shown",true)
var tour = new Tour({
storage: false,
backdrop: true,
onStart: function(){
$('body').addClass('is-touring');
},
onEnd: function(){
$('body').removeClass('is-touring');
},
steps: [
{
element: "#navbar-logo",
title: "Go Home",
content: "All throughout the app, you can click our logo to get back to the main page."
},
{
element: "input#top-search",
title: "Search",
content: "Here you can search for players by their name, school, positions & bib color (that they wore in our tournament)"
}
]});
// Initialize the tour
tour.init();
// Start the tour
tour.start();
};
});
</script>
The cookie class is verbose. You can just use $.cookie to achieve simple one toggle behavior. The above code works for all first time users, logged-in as well as logged-out. If you just want it for logged-in user, set the flag on user log-in on server-side.
To use local storage:
if (typeof(Storage) !== "undefined") {
var takenTour = localStorage.getItem("takenTour");
if (!takenTour) {
localStorage.setItem("takenTour", true);
// Take the tour
}
}
We use this solution because our users don't log in, and it is a bit lighter than using cookies. As mentioned above it doesn't work when users switch machines or clear the cache, but you have that covered off by your login count.
Based on your comment, I think you're going to want to track this in your data (which is effectively what you're doing with the user.sign_in_count > 1 check). My recommendation would be to use a lightweight key-value data store like Redis.
In this model, each time a user visits a page that has this feature, you check for a "visited" value associated with that user in Redis. If it doesn't exist, you trigger the JS event and add "visited": true to Redis for that user, which will prevent the JS from triggering in the future.
Local storage is not a cross browser solution. Try this cross browser SQL implementation which uses different methods (including localstorage) to store 'databases' on the users hard drive indefinitely.
var visited;
jSQL.load(function(){
// create a table
jSQL.query("create table if not exists visits (time date)").execute();
// check if the user visited
visited = jSQL.query("select * from visits").execute().fetchAll("ASSOC").length;
// update the table so we know they visited already next time
jSQL.query("insert into visits values (?)").execute([new Date()]);
jSQL.persist();
});
This should work if what you want to do is gate the page for its life. If you need to prevent re-execution for longer periods, consider localStorage.
var triggered;
$(document).on('turbolinks:load', function() {
if (triggered === undefined) {
triggered = "yes";
...code...
}}
You're going to have to communicate with the backend somehow to get sign-in count. Either in a injected variable, or as json route you hit with ajax, do logic like:
if !session[:seen_tour] && current_user.sign_in_count == 1
#show_tour = true
session[:seen_tour] = true
else
#show_tour = false
end
respond_to do |format|
format.html {}
format.json { render json: {show_tour: #show_tour } }
end
Values in session will persist however you've configured your session store, by default that is stored in cookies.

Template helper gets called multiple times

My intention is to retrieve one random entry from a collection and display it on the website - if all sentences are through (read: the user has "seen" them), display something else (therefore a dummy sentence gets returned). But, on server start and on button-click events, this helper gets fired at least twice. Here is some code:
In client.js:
Template.registerHelper('random_sentence', function() {
fetched = _.shuffle(Sentences.find({
users: {
$nin: [this.userId]
}
}).fetch())[0];
if (fetched === undefined) {
return {
sentence: "done",
_id: 0,
done: true
};
}
Session.set('question', fetched._id);
console.log(fetched);
return fetched;
});
The helper function for the template:
sent: function(){
sent = Session.get('question');
return Sentences.findOne(sent);
}
in main template:
{{#with random_sentence}}
{{#if done}}
<!-- Display something else -->
{{else}}
<div class="container">
{{> question}}
</div>
{{/if}}
{{/with}}
the "question" template:
<div class="well">
<div class="panel-body text-center">
<h3>{{sent.sentence}}</h3>
</div>
</div>
If I don't return anything in the "random_sentences"-function,nothing get's displayed.
I don't know where my "logic failure" is situated? I'm new to meteor - so I might overlook something obvious.
Thanks in advance :-)
UPDATE: This is how I intended to get the new sentence and display it:
Template.answer.events({
'click': function(event) {
var text = event.target.getAttribute('id');
if (text !== null) {
var question = Session.get('question');
var setModifier = {
$inc: {}
};
setModifier.$inc[text] = 1;
Sentences.update(question, setModifier);
Meteor.call('update_user', question);
Notifications.success('Danke!', 'Deine Beurteilung wurde gespeichert.');
Blaze.render(Template.question, document.head);
}
}
});
In server.js (updating the question and a counter on the user):
Meteor.methods({
update_user: function(question) {
Sentences.update(question, {
$push: {
"users": this.userId
}
});
Meteor.users.update({
_id: this.userId
}, {
$inc: {
"profile.counter": 1
}
});
},
});
I found the Blaze.render function somewhere on the web. the "document.head" part is simply because this function needs a DOM Element to render to, and since document.body just "multiplies" the body, I ust moved it to the head. (DOM logic isn't my strong part).
An Idea I had: would it make the whole idea simpler to implement with iron-router? atm. I wanted to create a "one-page app" - I therefore thought that I don't need a router there.
Another problem: Getting this logic to work (User gets one random sentence, which he has not seen) and publishing small sets of the collection (so the Client don't have to download 5 MB of data before using).
Template helpers can be called multiple times so it's good to avoid making them stateful. You're better off selecting the random entry in an onCreated or onRendered template handler. There you can do your random select, update the state, and put your choice in a Session variable to be retrieved by the helper.

Pull down to refresh in Kendo-UI, text overlaps showing both "release" and "pull" labels

I have a problem with the pull down refresh. It works the first time, but then if I change to a different view, then come back to the original view, the Pull to refresh and Release to refresh text seem to get duplicated and overlapped on itself. I am "hardcoding" the datasource's data here, I don't want to use the transport ajax.
I am trying to manually update the data in the setOptions pull method, instead of letting Kendo update it via ajax. The actual data update works. There are no Javascript errors and I get the same result in Chrome and Firefox.
First time works:
After moving to another view, then back to this view, then pulling down:
My view code is:
<div id="subitem-view" data-role="view" data-show="showSubItems">
<div data-role="header">
<div data-role="navbar">
</div>
</div>
<ul id="subItemList" class="itemList">
</ul>
<script id="subItemTemplate" type="text/x-kendo-template">
#:Name#
</script>
</div>
Javascript:
function showSubItems(e) {
var subItems = new kendo.data.DataSource({
data: [
{ Name : "Test1" },
{ Name : "Test2" }
]
});
e.view.element.find("#subItemList").kendoMobileListView({
dataSource: subItems,
pullToRefresh: true,
template: kendo.template($("#subItemTemplate").html())
});
if (typeof (e.view.scroller.pull) == "undefined") {
e.view.scroller.setOptions({
pull: function () {
console.log("pull event...");
subItems.data([
{ Name : "Test1 Updated" },
{ Name : "Test2 Updated" }
]);
setTimeout(function () { e.view.scroller.pullHandled(); }, 400);
}
});
}
}
You're initializing your Kendo UI Mobile ListView on every View show which leads to unpredictable results, like recreating the pull to refresh labels. You should do it in the Init event only.
