JQuery bind click event keep old binding values - jquery-ui

I have an ASP.NET MVC 3.0 partial view which is render inside a jquery ui dialog.
Inside this partial view I have some link which help me to display some more info.
#foreach (StatusType status in ViewBag.Status)
{
<li>#status.StatusMessage<a href='#' status='#status.StatusCode'><img src=#Url.Content("~/Content/Images/information.png") alt="See detail"/></a></li>
}
I've bound those link with the click event:
$('a[status]').live('click', function (e) {
if (e.preventDefault)
e.preventDefault();
else
e.returnValue = false;
var status = $(this).attr('status');
alert('#Model.Code');
...});
What is happening is when I click the first time on the link it will display me the correct Code (let's say 12). When I will load the partial view again for another code (66) it will display me two alert message, the first one with 12 (the old value I've clicked before) and the second one with 66.
The more partial view I will load the more value I will have in my alert.
I don't understand why it is keeping me like an history of all the code I've clicked.
If somebody have any idea on this problem, it will be welcomed, it just driving me mad.
Thanks in advance.
UPDATED
The use of the on instead of the live works, but I still have an issue with the dialog.
I've change the code with the solution proposed:
$('#StatusDiv').on('click', 'a[status]', function (e) {
e.preventDefault();
var status = $(this).attr('status');
alert('#Model.Code');
$('#StatusDialog').dialog({
autoOpen: false,
width: 800,
resizable: true,
title: 'Status Info',
modal: true,
open: function (event, ui) {
alert('#Model.Code');
$(this).load('#Url.Action("ViewStatusInfo")', { clientId: clientId, Code: '#Model.Code', status: status
});
}
});
$('#StatusDialog').dialog('open');
});
The first alert display the correct code, but the second alert inside the open function display the old one. On the second click it will work correctly but I don't understand how it can pick the old value since the first display is correct...
Thanks again for your help.

First of all: do not use live in last versions of jquery.
$('#list').on('click', '.status', function(e){
e.preventDefault();
alert(this.href);
});
Here we bind event to #list and when we will insert new links, everything will work.

jquery mobile 1.4 not updating content on page transition

From the index page, a user clicks a navigation link, the data attribute is passed via ajax, the data is retrieved from the server but the content is not being updated on the new page.
Been stuck for hours, really appreciate any help!
js
$('a.navLink').on('click', function() {
var cat = $(this).data("cat");
console.log(cat);
$.ajax({
url: 'scripts/categoryGet.php',
type: 'POST',
dataType: "json",
data: {'cat': cat},
success: function(data) {
var title = data[0][0],
description = data[0][1];
console.log(title);
$('#categoryTitle').html(title);
$('#categoryTitle').trigger("refresh");
$('#categoryDescription').html(description);
$('#categoryDescription').trigger("refresh");
}
});
});
Im getting the correct responses back on both console logs, so I know the works, but neither divs categoryTitle or categoryDescription are being updated. I've tried .trigger('refresh'), .trigger('updatelayout') but no luck!
This was not intended to be an answer (but I can't comment yet.. (weird SO rules)
You should specify in the question description that the above code IS working, that your problem occurs WHEN your playing back and forth on that page/code aka, using the JQM ajax navigation.
From what I understood in the above comment, you're probably "stacking" the ajax function every time you return to the page, thus getting weird results, if nothing at all.
Is your example code wrapped into something ? If not, (assuming you use JQM v1.4) you should consider wrapping it into $( 'body' ).on( 'pagecontainercreate', function( event, ui ) {... which I'm trying to figure out myself how to best play with..
Simple solution to prevent stacking the ajax definition would be to create/use a control var, here is a way to do so:
var navLinkCatchClick = {
loaded: false,
launchAjax: function(){
if ( !this.loaded ){
this.ajaxCall();
}
},
ajaxCall: function(){
// paste you example code here..
this.loaded = true;
}
}
navLinkCatchClick.launchAjax();

how to display pop up on another page on success of post method in mobile jquery?

i am working on a project which is based on jquery Mobile. i am a biggner in this field, so sorry for the silly question. the question is -- i have a page 'Page1' and i am using post method to fetch data from database. On success i am showing a notification to user through a notification dialog(without cancel and ok button). now what i want this success message on another page "page2", and the message should be there up to 2 sec and then disappear automatically. i have tried
function sendAddGuest(data, dialog) {
$.post("/GuestsList/AddGuest", data, function (response) { //using the post method
//alert(JSON.stringify(response));
$('.error').html("");
hideLoading();
if (response.result == 'success') { //if the process done
$.mobile.changePage('/GuestsList/Index', { dataUrl: "/GuestsList/Index", reloadPage: false, changeHash: true }); //To another page "page2"
// window.setTimeout('showToastMessage("Guest added successfully with window");',2000); //i have tried this
setTimeout(function () { showToastMessage("Guest added successfully test2"); }, 100); //and this also i want to show this message on other page "page2"
}
}
I am also beginning with Jquery Mobile, based in the toy project I am working with I would suggest the following:
Use popup from jquerymobile instead of showToast, then you could call
the .close() of the element in the settimeout function.
This is the div you create for your popup (you put it in the page 2):
<div data-role="popup" id="myPopup" class="ui-content" data-theme="e">
<p>Guest added successfully</p>
</div>
This is how you could call the function to open once in the new page (use the pageload event):
$('#myPopup').popup('open');
This is how you could call the function to close (in the same pageload event):
window.setTimeout(function(){ $('#myPopup').popup('close'); }, 2000)
Sorry I have no time to code a complete example, but I think this is the way to go.
Hope this helps!:-)

jQuery UI Autocompleteselect

I am trying to get my form to submit when a user either clicks enter or mouse clicks. I have seen some examples as well as the example on the jQuery UI site. The example that I am following is jQuery UI autocomplete submit onclick result. Therefore my code looks like this.
<script type="text/javascript">
$(document).ready(function() {
$("#myInput").autocomplete({
source: "fh_autocomplete_search.php",
minLength: 2,
select: function(event, ui) {
if(ui.item){
$("#myInput").value(ui.item.value);
}
$("#myInput").submit();
}
});
$( "#myInput" ).bind( "autocompleteselect", function(event, ui) {
})
});
</script>
I'm not sure what should go under the .bind section of the code. Or really what it is even doing. And I have been here and read it but still just not clicking http://api.jquery.com/bind/ When I put an alert under it and select a ui.item from the #myInput box the alert does go off. But nothing fills or submits. If I put an alert under the if(ui.item) part it doesn't go off. If someone could explain to me what is going on and suggest some code to put under the .bind section I would greatly appreciate it.
If the id of the form is myForm:
$(document).ready(function() {
$("#myInput").autocomplete({
source: "fh_autocomplete_search.php",
minLength: 2,
select: function(event, ui) {
$("#myInput").val(ui.item.value);
$("#myForm").submit();
}
});
});
Also see this example.
I'm not entirely sure you need to write code for the "autocompleteselect" event. The default behavior of the event is to replace the text in the textbox with the users selection from the menu of items.

jQuery UI: Show dialog that user must confirm or cancel

I have a few links on my site that will need to show a modal dialog when the user clicks on one of them. The modal will contain a message like: You are now leaving the "SECTION NAME" part of "SITE NAME". The user will then either accept which will allow the user to continue on with their request or cancel which will keep the user where they are.
An example of a link would be: My Interests
So as you can see the class of leaving-section would cause the link to do what I have specified above, and will also open the link in a new tab/window BUT the user must first accept that they are aware they are being taken to another part of the site.
I have looked at the docs but I haven't seen any examples where a) the dialog is created on the fly rather than hiding and showing a div and b) allowing the user to confirm and being sent to their original location i.e. the url which they clicked.
This is what I have so far:
$("#leaving-section").dialog({
resizable: false,
modal: true,
buttons: {
"I understand, take me there": function () {
$(this).dialog("close");
},
"I want to stay where I am": function () {
$(this).dialog("close");
}
}
});
$('.leaving-section').click(function (event)
{
event.preventDefault();
var $dialog = $('#leaving-section');
$dialog.dialog('open');
});
But I want to the modal to be created by jquery instead of the div being embedded in the page! Also how do I get the first button to send them off to their original destination?
Thanks to all who can help. Thanks
I just had to solve the same problem. The key to getting this to work was that the dialog must be partially initialized in the click event handler for the link you want to use the confirmation functionality with (if you want to use this for more than one link). This is because the target URL for the link must be injected into the event handler for the confirmation button click. I used a CSS class to indicate which links should have the confirmation behavior.
Here's my solution, abstracted away to be suitable for an example.
<div id="dialog" title="Confirmation Required">
Are you sure about this?
</div>
<script type="text/javascript">
$(document).ready(function() {
$("#dialog").dialog({
autoOpen: false,
modal: true
});
});
$(".confirmLink").click(function(e) {
e.preventDefault();
var targetUrl = $(this).attr("href");
$("#dialog").dialog({
buttons : {
"Confirm" : function() {
window.location.href = targetUrl;
},
"Cancel" : function() {
$(this).dialog("close");
}
}
});
$("#dialog").dialog("open");
});
</script>
<a class="confirmLink" href="http://someLinkWhichRequiresConfirmation.com">Click here</a>
<a class="confirmLink" href="http://anotherSensitiveLink">Or, you could click here</a>
I believe that this would work for you, if you can generate your links with the CSS class (confirmLink, in my example).
I think this plugin may be help
http://jqueryui.com/demos/dialog/#modal-confirmation
Heres an example of how you can do it:
http://jsfiddle.net/yFkgR/3/
Or to do something besides cancel
http://jsfiddle.net/yFkgR/4/
You can just define your own buttons. You can style the dialog box anyway you want, i just used the default.
also to use ajax to load the html you can take a look at:
jQuery UI Dialog window loaded within AJAX style jQuery UI Tabs
There is an open option you can use to load html from a remote web page. I jquery you can create a div just be doing
$("<div>");
it will create the closing tag too. Or as suggested in the post you can also use
$('a.ajax')

Initiate jQuery UI Dialog from a result of AJAX call

I have Page A which calls Page B using AJAX. Page B will be put in a div container in Page A. Within the result (which is Page B), there's a code that will initiate a jQuery UI Dialog. The div for the dialog is also in Page B. However, it doesn't work. I'd have to put the initiation code in Page A. So, if I want to put the initiation code in Page B, what should I do ?
The initiation code:
$('#dialog').dialog({
bgiframe: true,
autoOpen: false,
width: 300,
height: 300,
modal: true,
resizable: false,
buttons: {
'Create an account': function() { },
Cancel: function() { }
},
close: function() { }
});
I've also tried using $('div.dialog') as the selector (changed the id to class) and it does work, but everytime I request Page B (without reloading Page A), the dialog will multiply. For an example, the first time I requested Page B, one dialog will be opened. The second time I requested Page B, two dialogs will be opened.
Your approach isn't far off, you're just duplicating the dialog on the call when loading each time, so destroy the previous one, so instead of this:
$('div.dialog').dialog({ ...options... });
Call this:
$('div.dialog').dialog('destroy').dialog({ ...options... });
This prevents multiple dialogs from being instantiated for the same element. Alternatively, you can check if the dialog has been created on that element yet, like this:
$('div.dialog').filter(function() {
return $(this).closest('.ui-dialog').length === 0;
}).dialog({ ...options... });
This creates the dialog only on <div class="dialog"> elements that aren't already wrapped in a dialog.
You could do that using jQuery live function with custom event binding.
Everytime you make a call to Page B, you would have to trigger your custom event, so that the new dialog element can be binded in the event handler. The initiation code would have to be still in Page A if you follow this method.
