I am opening mvc view(s) inside a modal dialog.
I am trying to make a recursive call and the problem I am facing is : after the recursive call the view loads properly but none of the controls on the view work :
In Main.js :
$(function () {
$(document).on('click', '.ddlCart li', Mod.Carts);
}
Carts.js :
var Mod = Mod || {};
Mod.Carts = function (e) {
var ddlselectedVal = $(this).attr('id');
var selectedListinsCount = selected_Listings.length;
var SelectedMlsnums = selected_Listings.join();
var agentId = $("#AgentId").val();
var Action;
var EnvironmentURL = $("#EnvironmentURL").val();
var postData = { AgentId: agentId, Mlsnums: SelectedMlsnums, ActionTypeValue: “PreAddToCart” };
var close = function (event, ui) {
$('#dvModalDialog').dialog("close");
}
var open = function (event, ui) {
var url = EnvironmentURL + "MLSReports/Stats/SearchContacts";
$("#btncart_cancel").on("click", function () {
$('#dvModalDialog').dialog("close");
});
$("#btncart_submit").on("click", function () {
var url = EnvironmentURL + "MLSReports/Stats/Cart";
//Send the data using post and put the results in a div
$.post(url, {
AgentId: agentId, Mlsnums: SelectedMlsnums, ActionTypeValue: "AddToCart"
},
function (data) {
// Replace current data with data from the ajax call to the div.
$("#dvModalDialog").empty().append(data);
});
});
$("#lnkCreateNewcart").on("click", function () {
var url = EnvironmentURL + "MLSReports/Stats/Cart";
//Send the data using post and put the results in a div
$.post(url, {
ActionTypeValue: "preAddorEditContact"
},
function (data) {
//debugger;
// Replace current data with data from the ajax call to the div.
$("#dvModalDialog").empty().append(data);
$("#btnCancelContact").on("click", function () {
////********** replace the view (Contact) with the view (Cart).
// In the cancel event I am loading the previous page.I am having problem here. after a recursive call none of the controls work.**
// rd.open();
this.Mod.Carts();
});
});
});
};
if (ddlselectedVal == "AddtoCart") {
var rd = Mod.ReportsDialog({ title: 'Add To Cart', close: close, open: open });
rd.url = EnvironmentURL + "/MLSReports/Stats/Cart";
rd.targetElement = '#dvModalDialog'// '#dvSendEmail'
rd.formName = '#frmCart'
rd.postData = postData
rd.open();
}
};
The value of this inside of the referenced function is going to be different when this.Mod.Carts(); is used. You should use call in this scenario to bind the value of this to the proper value when calling the Carts function.
$("#btnCancelContact").on("click", function () {
Mod.Carts.call(this);
});

currently i'm starting with Ember, and i'm loving it! I'm with some difficulties, especially when it comes to components.
For you to understand, I'm going through old code to Ember, and I would like to turn this code into a Component, but I do not know actually how to start, since I do not know how to catch the button being clicked, and I also realized that Ember has several helpers, maybe I do not need any of this giant code to do what I want.
This is the old code result: http://codepen.io/anon/pen/WQjobV?editors=110
var eventObj = {};
var eventInstances = {};
var actual;
var others;
var clicked;

}
};

Basically i have this boxes, which box represent one booking in some event (will be populate by the server). When the user clicks in one box, this boxes expands and the other disappear. But than a dropbox will be created with the other boxes, so the user can navigate in the events by this dropdown.
I didn't do much with Ember, i transform the "events" div into a component with the name "BookingBoxComponent" and two actions:
SiteApp.BookingBoxComponent = Ember.Component.extend({
actions:
open: function() {
// HOW COULD I ACCESS THE CLICKED BUTTON HERE?
},
close: function() {
}
});
As you can see, i put two actions, one for opening the box and other for closing, should i just put the logic in both, or i can improve this like a Ember way?
I don't know if i am asking to much here, so if i am, at least i would like to know how to access the button clicked in the open method, i was trying passing as a parameter, like:
<button {{action 'open' this}}></button>
But didn't work.
I could offer 50 of my points to someone who help transform the old cold in a Ember way code.
Thanks.
The event object will be passed with every action as the last parameter, so when you specified this you were actually passing whatever object has context in that block. In your open function, do not pass this and do
open: function(event) {
// event.currentTarget would be the button
}
And now you can do something like event.currentTarget or event.target
Here is I have table built with knockout 'foreach'. After user select some rows, these rows will contain class 'success'. So I want to use self.create event that fire after user press button (button located outside element that ViewModel binded to) in order to handle such table rows. But Firebug said: TypeError: GrafikViewModel.books is undefined.
Here is the code:
function InfoViewModel(baseUri) {
//some viewmodel here
}
//This is viewmodel I'm talking about.
function GrafikViewModel(grafikUri) {
var self = this;
self.books = ko.observableArray();
self.create = function () {
//Here we will handle tr with class 'success'
alert("!!!");
}
$.getJSON(grafikUri, function (data) {
self.books(data.$values);
});
}
$(document).ready(function () {
var url = location.href.split("/");
var baseUri;
var tkod = url[5];
if (url[4].toString = 'x') {
baseUri = '/api/xTourist/' + tkod;
}
else if (url[4].toString = 'y') {
baseUri = '/api/yTourist/' + tkod;
}
var grafikUri = '/api/grafik/' + tkod;
ko.applyBindings(InfoViewModel(baseUri), document.getElementById('info'));
ko.applyBindings(new GrafikViewModel(grafikUri), document.getElementById('grafik'));
$('#book').click(function () {
//Here I'm trying to call ViewModel.
GrafikViewModel.books.create(ko.dataFor(this));
});
});
try new GrafikViewModel().books.create(ko.dataFor(this));
I am attempting to perform some action on the foucsin of the textbox. However, for some reason the event never fires.
$(".ddlAddListinTo li").click(function () {
var urlstring = "../ActionTypes";
$.post(urlstring, function (data) {
$(window.open(urlstring, 'Contacts', 'width=750, height=400')).load(function (e) {
// Here "this" will be the pop up window.
$(this.document).find('#txtAutocompleteContact').on({
'focusin': function (event) {
alert('You are inside the Contact text box of the Contacts Popup');
}
});
});
});
});
When doing it that way, you generally have to find the body or use contents() to access the contents, as in
$(this.document).contents().find('#txtAutocompleteContact')
but in this case using a little plain javascript seems more appropriate :
$(".ddlAddListinTo li").on('click', function () {
var urlstring = "../ActionTypes";
$.post(urlstring, function (data) {
var wind = window.open(urlstring, 'Contacts', 'width=750, height=400');
wind.onload = function() {
var elem = this.document.getElementById('txtAutocompleteContact');
$(elem).on('focus', function() {
alert('You are inside the Contact text box of the Contacts Popup');
});
}
});
});
I am trying to load xml data and everything works good, but I would like reload xml data when device resume.
This is my code, and I don't know where to paste function for load on resume. Thanks for advices ;-)
var TITLE = "Example";
var XMLsoubor = "example.xml";
var entries = [];
var selectedEntry = "";
//listen for detail links
$(".contentLink").live("click", function () {
selectedEntry = $(this).data("entryid");
});
//Listen for main page
$("#mainPage").live("pageinit", function () {
//Set the title
$("h1", this).text(TITLE);
$.ajax({
url: XMLsoubor,
success: function (res, code) {
entries = [];
var xml = $(res);
var items = xml.find("event");
$.each(items, function (i, v) {
entry = {
title: $(v).find("id").text(),
link: $(v).find("begin").text(),
description: $.trim($(v).find("description").text())
};
entries.push(entry);
});
//store entries
localStorage["entries"] = JSON.stringify(entries);
renderEntries(entries);
},
error: function (jqXHR, status, error) {
//try to use cache
if (localStorage["entries"]) {
$("#status").html("Error");
entries = JSON.parse(localStorage["entries"])
renderEntries(entries);
} else {
$("#status").html("Error");
}
}
});
});
$("#mainPage").live("pagebeforeshow", function (event, data) {
if (data.prevPage.length) {
$("h1", data.prevPage).text("");
$("#entryText", data.prevPage).html("");
};
});
//Listen for the content page to load
$("#contentPage").live("pageshow", function (prepage) {
//Set the title
$("h1", this).text(entries[selectedEntry].title);
var contentHTML = "";
contentHTML += entries[selectedEntry].description;
contentHTML += '<p/><br><br><br>text';
$("#entryText", this).html(contentHTML);
});
function renderEntries(entries) {
var s = '';
$.each(entries, function (i, v) {
s += '<li>' + v.title + '<br>text</li>';
});
$("#linksList").html(s);
$("#linksList").listview("refresh");
}
Use the eventlistener for "resume". It should be made as soon as deviceready has fired.
http://docs.phonegap.com/en/2.9.0/cordova_events_events.md.html#resume
The very first thing you should have in your script is an event for deviceready because a lot of Cordova things aren't ready until the deviceready event has been fired, so you need to listen for deviceready, like this:
document.addEventListener("deviceready", onDeviceReady, false);
Then you add the other listeners in the onDeviceReady function and begin the rest of your app start up from there:
function onDeviceReady() {
//The device is ready when this function is called
document.addEventListener("resume", appReturnedFromBackground, false);
}
function appReturnedFromBackground() {
//This function is called when the app has returned from the background
alert("The app has returned from the background");
}
With alot of help from #kalley we have found out that If I comment the following two lines out the LAG is gone!
var $tableContents = $table.find('tbody')
var $html = $('<tbody/>').html(data);
But how do I keep the above but cancel out the LAG ?
MORE INFO:
The code below works but the problem is that the $.GET is causing the browser to hang until the ajax request completes. I need (flow control?) or something that will solve this problem without locking/hanging up the browser until ajax completes the GET request.
The biggest LAG/Lockup/Hang is at $.get("updatetable.php", since the others only return 7 or less (number) values and this one ('updatetable.php') returns alot more (200-300kb). I would like to implement some sort of flow control here or make the script wait like 5 secs before firing the update command for tablesort and before showing the toast message so that ajax has time to GET the $.get("updatetable.php"data I just don't understand why does it lockup the browser as it is getting the data? is it trying to fire the other commands and that's whats causing the LAG?
Here are the STEPS
1.
$.get("getlastupdate.php" Will fire every 10 secs or so to check if the date and time are the same the return data looks like this: 20130812092636 the format is: YYYmmddHHmmss.
2.
if the date and time are not the same as the last GET then $.get("getlastupdate2.php" will trigger and this data will be send back and placed into a toast message and dispalyed to the user $().toastmessage('showNoticeToast', Vinfoo);
3.
before or after the above ($.get("getlastupdate2.php") another GET will fire: $.get('updatetable.php' this will GET the updated table info. and replace the old one with the new info. and then update/resort the table
4.
at the end of it all I want to $.get("ajaxcontrol.php" and this will return a 1 or 2 if the user is logged in then it will be a 2 else it's a 1 and it will destroy the session and log the user out.

Maybe instead of using setInterval, you should consider switching to setTimeout. It will give you more control over when the time repeats:
function checkComper() {
var SvInfo;
var onResponse = function (comperNow) {
if (comper === undefined) {
comper = comperNow;
} else if (comper !== comperNow) {
var Vinfoo;
comper = comperNow;
// returning this $.get will make delay done until this is done.
return $.get("getlastupdate2.php", function (primaryAddType) {
Vinfoo = primaryAddType;
$().toastmessage('showNoticeToast', Vinfoo);
}).then(checkSession);
}
};
$.get('getlastupdate.php').then(onResponse).done(function () {
tid = setTimeout(checkComper, 10000);
});
}
var tid = setTimeout(checkComper, 10000);
Then you can keep it async: true
Here's a fiddle showing it working using echo.jsontest.com and some fudging numbers.
Since the click event callback seems to be where the issue is, try doing this and see if it removes the lag (I removed other comments to make it more brief):
function checkSession() {
return $.get("ajaxcontrol.php", function (DblIn) {
console.log('checking for session');
if (DblIn == 1) {
window.location = 'loggedout.php';
}
}).then(updateTable);
}
function updateTable() {
return $.get('updatetable.php', function (data) {
console.log('update table');
var $tableContents = $table.find('tbody')
//var $html = $('<tbody/>').html(data);
//$tableContents.replaceWith($html);
// replaceWith text seems to be much faster:
// http://jsperf.com/jquery-html-vs-replacewith/4
$tableContents.replaceWith('<tbody'> + data + '</tbody>');
//$table.trigger("update", [true]);
var currentUrl = document.getElementById("frmcontent").contentWindow.location.href;
var urls = ['indexTOM.php', 'index1.php'],
frame = document.getElementById('frmcontent').contentDocument;
for (var i = 0; i < urls.length; i++) {
var url = urls[i];
if (frame.location.href.indexOf(url) !== -1) {
frame.location.reload()
}
}
$('[title!=""]').qtip({});
});
};
$("#append").click(function (e) {
// We will assume this is a user action
e.preventDefault();
updateTable();
});
I commented out $table.trigger("update", [true]) since if you sort the table on the server before you return it, you shouldn't need to run that, which I'm almost certain is where the bottleneck is.
It is really hard untangle the mess you have but if what you want is ajax requests every 10 seconds it make sense to separate this logic from business logic over data from server.
Your code would also really benefit from using promises. Consider this example
$(document).ready(function() {
var myData = { }
, ajaxPromise = null
setInterval(callServer, 1000)
function callServer() {
ajaxPromise = updateCall()
.then(controlCall)
.done(handler)
.error(errorHandler)
}
function updateCall() {
return $.get('updateTable.php', function(data) {
myData.update = data
})
}
function controlCall( ) {
return $.get('ajaxControl.php', function(data) {
myData.control = data
})
}
function handler() {
console.dir(myData)
}
function errorHandler(err) {
console.log(err)
console.dir(myData)
}
})
