Return text when checkbox selected

In my site, I have a form that users can click on a checkbox to select "available". I want to have "Yes" or "No" returned in the displayArticle function based on whether the box is checked or not. Right now it returns True or False, which is not optimal. How can I code this?
Here is my entire JS code:
App = {
web3Provider: null,
contracts: {},
account: 0x0,
loading: false,
init: function() {
return App.initWeb3();
},
initWeb3: function() {
// initialize web3
if(typeof web3 !== 'undefined') {
//reuse the provider of the Web3 object injected by Metamask
App.web3Provider = web3.currentProvider;
} else {
//create a new provider and plug it directly into our local node
App.web3Provider = new Web3.providers.HttpProvider('http://localhost:7545');
}
web3 = new Web3(App.web3Provider);
App.displayAccountInfo();
return App.initContract();
},
displayAccountInfo: function() {
web3.eth.getCoinbase(function(err, account) {
if(err === null) {
App.account = account;
$('#account').text(account);
web3.eth.getBalance(account, function(err, balance) {
if(err === null) {
$('#accountBalance').text(web3.fromWei(balance, "ether") + " ETH");
}
})
}
});
},
initContract: function() {
$.getJSON('RentalContract.json', function(chainListArtifact) {
//added May24 to json file name
// get the contract artifact file and use it to instantiate a truffle contract abstraction
App.contracts.RentalContract = TruffleContract(chainListArtifact);
// set the provider for our contracts
App.contracts.RentalContract.setProvider(App.web3Provider);
// listen to events
App.listenToEvents();
// retrieve the article from the contract
return App.reloadArticles();
});
},
reloadArticles: function() {
//avoid reentry bugs
if(App.loading){
return;
}
App.loading = true;
// refresh account information because the balance might have changed
App.displayAccountInfo();
var chainListInstance;
App.contracts.RentalContract.deployed().then(function(instance) {

If I understand what you're trying to do, perhaps this will work for you.
var isChecked = '';
if (articleTemplate.find('.available').checked === true)
{ isChecked = 'yes'} else
{ isChecked = 'no'}
.
.
.
return isChecked;

Do this:
articleTemplate.find( '.available' ).text( available ? 'Yes' : 'No' );
Example:
function returnValue() {
$( '#val' ).text( $( '#chk' ).is( ':checked' ) ? 'Yes' : 'No' )
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" id="chk" onclick="returnValue()" />
<label for="chk">Available</label>
<h2 id="val"></h2>

Setup jqueryui before element is rendered

In creating a table cells with very cool options I need to take two steps. First I create the table cell as a DOM object in javascript with all the 'normal' functionality, like is it a checkbox, a select, an input, a link, etc.
Then I need to put the table on the page to do the next step, which I consider advanced functionality like jqueryui's autocomplete and date select. It is awesome to have these drop downs for the user.
I do have this working, however, I do need to make two calls. The first to createTableCell, then I render, then I need to make another call to postRenderTableFunctions to get the autocomplete functionality working. So the question is, why the second call, what is it about jqueryui that will not work on the first call. You can see the commented section under input creation where I tried to get the autocomplete working.
function createTableCell(name, td_def)
{
var cell=document.createElement('td');

My original comment to your question -
I suspect i may work if you replace
$( "#" + name ).autocomplete({
with
$(element).autocomplete({
though I don't currently have means to test it.
My response -
Basically using $("#name") looks for an element with the ID name in the DOM. When you are running your code element has not been added to the DOM yet so the autocomplete cannot be attached to to your element.
Surrounding element with $() converts it to a jQuery variable which you can attach the autocomplete to before it is added to the DOM.

How can I create chrome.notification real Time?

Using the google chrome Api extension, I have the following code that show notification from JSON. Once notification is show, and when I clicked on it opened multiple tabs url (It's an error). I need to solve that problem because this should open only one tab url, this is the only problem. look the code below:
var timeChange = 1000, jsons = ['JSON_URL'];
updateValue = function() {
var colorStatus = 0;
chrome.storage.local.get(function (dataStorage) {
$.getJSON(jsons+'?'+$.now(), function (data) {
var jLastPost = {'LastNotification':''}, sizePost = (data.results.length - 1), dataLastPost = data.results[0];
totalEntradas = data.totalEntradas ? data.totalEntradas : '';
$.each(data.results, function (k,v) {
if (($.inArray('post-'+v.id, dataStorage.IDs) !== -1) && (v.date_status > 0)) {
colorStatus = 1;
}
});
chrome.browserAction.setBadgeText({'text': totalEntradas.toString()});
if (dataStorage.LastNotification !== dataLastPost.id)
{
jLastPost.LastNotification = dataLastPost.id;
chrome.storage.local.set(jLastPost);
chrome.notifications.create(dataLastPost.id,{
type: 'basic',
title: dataLastPost.titulo,
message: 'Now for you!',
iconUrl: dataLastPost.image
}, function (id) {});
chrome.notifications.onClicked.addListener(function () {
chrome.tabs.create({url: dataLastPost.uri});
});
chrome.notifications.clear(dataLastPost.id, function() {});
return false;
}
});
});
setTimeout(updateValue, timeChange);
}
updateValue();

You are attaching a chrome.notifications.onClicked listener every second when you run updateValue. At a minimum you should move the listener outside of the method.
Something along these lines should work.
var timeChange = 1000, jsons = ['JSON_URL'];
var lastPostUri;
chrome.notifications.onClicked.addListener(function () {
if (lastPostUri) {
chrome.tabs.create({url: lastPostUri});
}
});
updateValue = function() {
var colorStatus = 0;
chrome.storage.local.get(function (dataStorage) {
$.getJSON(jsons+'?'+$.now(), function (data) {
var jLastPost = {'LastNotification':''}, sizePost = (data.results.length - 1), dataLastPost = data.results[0];
totalEntradas = data.totalEntradas ? data.totalEntradas : '';
$.each(data.results, function (k,v) {
if (($.inArray('post-'+v.id, dataStorage.IDs) !== -1) && (v.date_status > 0)) {
colorStatus = 1;
}
});
chrome.browserAction.setBadgeText({'text': totalEntradas.toString()});
if (dataStorage.LastNotification !== dataLastPost.id)
{
jLastPost.LastNotification = dataLastPost.id;
chrome.storage.local.set(jLastPost);
lastPostUri = dataLastPost.uri
chrome.notifications.create(dataLastPost.id,{
type: 'basic',
title: dataLastPost.titulo,
message: 'Now for you!',
iconUrl: dataLastPost.image
}, function (id) {});
chrome.notifications.clear(dataLastPost.id, function() {});
return false;
}
});
});
setTimeout(updateValue, timeChange);
}
updateValue();

click event not completely working, using Knockout.js binding and viewmodel

hi this is my code snippet:
self.arrow = function () {
alert("button clicked");
var active_el = $(this);
$('.movie-listing-header').each(function () {
if ($(this).get(0) === active_el.parent().get(0)) {
if ($(this).hasClass('active')) {
$(this).siblings('.showtimes').hide();
} else {
$(this).siblings('.showtimes').show();
}
$(this).toggleClass('active');
} else {
$(this).removeClass('active');
$(this).siblings('.showtimes').hide();
}
});
}
it is part of my viewmodel, and the alert("button clicked") works, but the rest of the code does not ... Here is the button click code:
<a class="icon arrow" data-bind="click: $parent.arrow"></a>
my question is HOW do I get the code after the alert to function.
this is the entire js, containing the the View Model
function TheatreViewModel(theatre) {
var self = this,
initialData = theatre || Regal.userPrimaryTheatre || {},
theatreServiceParams = {
tmsId: initialData.TmsId,
date: initialData.selectedDate || new Date()
};
self.TheatreName = initialData.TheatreName || '';
self.PhoneNumber = initialData.PhoneNumber || '';
self.selectedTheatreTms = initialData.TmsId;
self.theatre = ko.observable();
self.isLoading = ko.observable(false);
self.selectedDate = ko.observable(initialData.selectedDate || new Date());
self.filterFormats = [];
self.selectedFormat = ko.observable(Regal.allFormatsFilterItem);
self.filterFormats.push(Regal.allFormatsFilterItem);
if (Regal.movieFormats) {
var filtered = _.where(Regal.movieFormats, {
Filterable: true
});
_.forEach(filtered, function(f) {
f.enabled = ko.observable(false);
self.filterFormats.push(f);
});
}
self.addressText = ko.computed(function() {
var theat = ko.unwrap(self.theatre);
var addie;
if (!theat || theat && !theat.Address1) {
addie = initialData;
} else {
addie = theat;
}
return addie.Address1 + ', ' + addie.City + ' ' + addie.State + ' ' + addie.PostalCode;
});
self.mapEmbedUrl = ko.computed(function() {
var a = self.addressText();
return 'http://maps.google.com/maps?q=' + encodeURI(a);
});
self.movies = ko.computed(function() {
var thea = self.theatre(),
mov = ko.unwrap((thea || {}).Movies),
format = self.selectedFormat();
if (format && format !== Regal.allFormatsFilterItem) {
return _.filter(mov, function(m) {
return _.contains(_.pluck(m.formats(), 'Id'), format.Id);
});
}
return mov;
});
self.getPerformances = function() {
self.isLoading(true);
Regal.loadTheatre(self.selectedDate(), self.selectedTheatreTms,
function(data) {
self.isLoading(false);
if (data) {
var allFmts = _.uniq(_.flatten(_.map(ko.unwrap(data.Movies), function(mov) {
return mov.formats();
})));
_.forEach(allFmts, function(fmt) {
var filt = _.findWhere(self.filterFormats, {
Id: fmt.Id
});
if (filt) {
filt.enabled(true);
}
});
self.theatre(data);
}
});
};
self.changeFormat = function(format) {
console.log(format);
self.selectedFormat(format);
self.movies();
};
self.selectedDate.subscribe(function(newVal) {
self.getPerformances();
});
self.getPerformances();
self.arrow = function () {
alert("button clicked");
var active_el = $(this);
$('.movie-listing-header').each(function () {
if ($(this).get(0) === active_el.parent().get(0)) {
if ($(this).hasClass('active')) {
$(this).siblings('.showtimes').hide();
} else {
$(this).siblings('.showtimes').show();
}
$(this).toggleClass('active');
} else {
$(this).removeClass('active');
$(this).siblings('.showtimes').hide();
}
});
}
}

I have a feeling that var active_el = $(this) is not what you're expecting. I'm not running the code but I believe that this will be self in this context. However, I'd like to recommend a more fundamental MVVM change. Rather than including all this jQuery code for updating the UI, I would recommend setting properties on your view model instead. Here's a simplified example:
HTML
<section data-bind="foreach: movies">
<article>
<div data-bind="if: displayShowtimes">
<!-- ... show times UI -->
</div>
</article>
</section>
JavaScript
self.arrow = function (movie) {
movie.isActive(!movie.isActive());
}
This will make your JavaScript much less brittle to changes in the HTML.

restricting input tags to maximum 5

I have got following jquery tags plugin.
I want to to restrict maxmimum 5 tags, so that user can not enter more than 5 words (separated by spaces).
Can someone please help me doing it?

best way is to count the number of "tag" classes already added, and then you can handle it differently, for example you can prevent showing the "add a tag" input once 5 tags inserted by defining maxTags and updating jQuery.fn.addTag and jQuery.fn.removeTag :

How about adding something like this:
if($('.tag').length>=5){
$('#tags_tag').attr('disabled','true');
}
I put a little more flair into my demo.

Probably the easiest solution is to change line 89 of jquery.tagsinput.js from:
var skipTag = $(tagslist).tagExist(value);
to:
var skipTag = $(tagslist).length > 5 || $(tagslist).tagExist(value);
