listview is not showing the data in another page using jquery mobile - jquery-mobile

i am newly working for jquery mobile panels, i have tried the reference of this jsfiddle link here http://jsfiddle.net/Gajotres/vds2U/47/ , i just added jquery ajax call to parse xml data. My problem is after searching city and keyword in page1, ajax call shows success alert but not trigger to page2. I want to display data in page2. If i click on page2 in jquery panel it appends the searched data. What wrongs here If any changes need to do please help me. My code is like below:
html code:
<div data-role="panel" data-display="push" data-theme="b" id="nav-panel" data-position="left">
<h2> All Pages </h2>
<ul data-role="listview" data-icon="false">
<li data-icon="delete">Close menu</li>
<li>Main panel page</li>
<li>page 1 page</li>
<li>page 2 Page</li>
</ul>
</div>
<div data-role="page" id="panel-main" data-title="Panel main" data-theme="a" >
<div data-role="header" data-position="fixed">
<h1 id="header1">main panel</h1>
Menu
</div>
<div role="main" class="ui-content"">
<p id="para1">main panel</p>
</div>
</div>
<div data-role="page" id="page1" data-theme="a">
<div data-role="header" data-position="fixed">
<h1>page 1</h1>
Menu
</div>
<div data-role="main" class="ui-content">
<div class="text"><input type="text" id="p1" name="p1" placeholder="Location...." class="user-text1 textboxes" data-clear-btn="true" data-mini="true" />
</div>
<div class="height"></div>
<div class="text"><input type="text" id="p2" name="p2" placeholder="Term...." class="user-text2 textboxes" data-clear-btn="true" /></div>
<div class="height"></div>
<button type="submit" id="searchBtn" data-theme="f" data-corners="false"/>Search Events</button>
</div>
</div>
<div data-role="page" id="page2" data-theme="a" >
<div data-role="header" data-position="fixed">
<h1>page 2</h1>
Menu
</div>
<div data-role="main" class="ui-content">
<ul id="list" data-role="listview" data-icon="false" data-autodividers="true" data-theme="c"></ul>
</div>
</div>
<script>
$(function () {
$("[data-role=panel]").enhanceWithin().panel();
});
javascript code:
$(document).ready(function(){
$("#searchBtn").bind("click",function(){
// alert('success');
$.mobile.loading('show');
var p1=$("#p1").val();
var p2=$("#p2").val();
$.ajax({
type: 'GET',
url:"http://api2.yp.com/listings/v1/search?searchloc="+p1+"&term="+p2+&format=xml&key=5cbqjx3cdl",
dataType: "xml",
success: function(data){
//alert('success');
$(data).find("searchListing").each(function(){
var name=$(this).find("businessName").text();
var id=$(this).find("listingId").text();
window.location.href="#page2";
//$.mobile.changePage("#page2");
$.mobile.loading('hide');
$("#list").append('<li>name:'+ name +'</li>');
$("#list:visible").listview("refresh");
});//ajax ends
});
});

Use the jQM pagecreate instead of $(document).ready, then in the success function, append the new items to the list, navigate to page2 using pagecontainer("change"), then refresh the list:
$(document).on("pagecreate", "#page1", function(){
$("#searchBtn").on("click" ,function(){
// your AJAX code
success: function(data){
//alert('success');
$(data).find("searchListing").each(function(){
var name=$(this).find("businessName").text();
var id=$(this).find("listingId").text();
$.mobile.loading('hide');
$("#list").append('<li>name:'+ name +'</li>');
$("body").pagecontainer( "change", "#page2", {} );
$("#list").listview("refresh");
});
});
});
Simplified DEMO
I have left the AJAX out of the demo. I am just appending 3 items and then changing page.

jQuery Mobile - Prevent page navigation after changepage event is triggered

Basically the use case is this:
I have a form that the user is filling out a form and accidentally click another link. In the pagebeforehide event, I want to stop the navigation. I tried to do
event.stopPropagation();
event.preventDefault();
but neither of them stop the navigation from happening. Does anyone have any idea how to do this? It's not immediately clear how to handle this.
event.preventDefault(); should work if all your code is in the right places. Here is a simple example:
<div data-role="page" id="page1">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
<h1>My page</h1>
</div>
<div role="main" class="ui-content">
<label for="text-basic">Type 1 to allow navigation:</label>
<input type="text" name="text-basic" id="text-basic" value="" />
<br /><br />
<a class="ui-btn" href="#page2">Go to page 2</a>
</div>
<div data-role="footer" data-position="fixed" data-tap-toggle="false">
<h1>My page footer</h1>
</div>
</div>
<div data-role="page" id="page2">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
<h1>My page 2</h1>
</div>
<div role="main" class="ui-content">
page 2
<a class="ui-btn" href="#page1">Go back to page 1</a>
</div>
<div data-role="footer" data-position="fixed" data-tap-toggle="false">
<h1>My page footer</h1>
</div>
</div>
I have 2 pages and only want the user to go to page 2 if he/she types "1" into the text box.
$(document).on("pagecreate", "#page1", function(){
$( "body" ).on( "pagecontainerbeforetransition", function( event, ui ) {
var currPage = $( "body" ).pagecontainer( "getActivePage" ).prop("id");
if (currPage == "page1"){
var val = $("#text-basic").val();
if (val != "1") {
alert("you must enter 1 in the text box!");
event.preventDefault();
} else {
$("#text-basic").val("");
}
}
});
});
In the pagecontainer widget pagecontainerbeforetransition event, I see which page we are currently looking at, if it is page1, then check what the user has entered in the textbox. If I do not find the string "1", prevent navigation and alert the user.
Here is a working DEMO

Using data-prefetch in jQuery mobile 1.4.0

In my jQuery mobile app , I have used data-prefetch in order to prefetch Page1 , to increase the performance since each page take time to open and be shown to the user after clicking the link , the problem is that when I click on Page1 link once the app is lunched the pageinit/ pagecreate events for Page1 didn't executed , in this event I return data from the database to be displayed in a popup listview , but when I back to the home Page then click Page1 link a gain the Pageinit event executed and the data returned .
Why the Pageinit/ pagecreate events didn't work when prefetching a page ? How can I solve this problem ? since its very important to return the data in the Pagecreate or Pageinit event

jQuery mobile's loadpage() inserts an empty container

I am having an issue with the jQuery mobile's loadPage() method. I am using the method to load a popup container. When the page gets loaded, the #popup DIV is empty (no .header, .content, or .footer DIVs) when I inspect it. Am I doing something wrong?
HTML (popup.php)
<div id="popup" data-role="popup" data-overlay-theme="a">
<div class="header" data-role="header">
<h1>Title</h1>
</div>
<div class="content" data-role="content" data-iscroll>
Something.
</div>
<div class="footer" data-role="footer">
<a class="close" href="#" data-rel="back" data-role="button" data-inline="true" data-mini="true">Close</a>
</div>
</div>
JavaScript
$(document).on('pagecreate', '.find-page', function() {
// load popup once
if (!$('#popup').length) {
$.mobile.loadPage('popup.php', { changeHash: false });
}
});

How to get dynamically created data into a dialog box on listview click

I create a list view dynamically, but i have no clue on how i get the data from the selected list to appear in the dialog box. I have tried several ways but all failed. The only thing i have got going correctly is calling the dialog on click.
I want to display the whole message in the pop up dialog box
my code
<body>
<div data-role="page" id="messages">
<div data-theme="a" data-role="header">
<a data-role="button" href="index.html" data-transition="slide"
data-icon="arrow-l" data-iconpos="left" class="ui-btn-left">
Back
</a>
Refresh
<h3>
Alerts
</h3>
</div>
<div data-role="content">
<script type="text/javascript">
$(document).on("pagebeforeshow", "#messages", function() {
var uid = $.cookies.get( 'uid' );
if(uid == null){
$.mobile.changePage( "account-login.html", { transition: "slide"} );}
$(function(){
$.getJSON("ajaxResponder.php?method=messages",function(data){
var htmlString ="";
$.each(data.messages,function(index,item){
htmlString +='<li data-name='+item.msgid+'><a href="#">'+
'<h3 class="topic">'+item.subject+'</h3>' +
'<p>From: '+item.sender+'</p>' +
'<p>Date: '+item.added+'</p>' +
'<p>'+ item.message +'</p></a></li>' ;
});
$('#list').html(htmlString);
$('#list').listview('refresh');
});
});
});
</script>
<ul id="list" data-role="listview" data-theme="d"></ul>
</div>
<script>
$('#list').on('click', 'li', function() {
$.mobile.changePage("#dialog", {
role: "dialog"
});
});
</script>
</div>
<div data-role="page" data-rel="dialog" id="dialog" data-theme="c" data-close-btn="right">
<div data-role="header" data-position="fixed" data-theme="b">
<h1>New values added!</h1>
</div>
hello
<!-- display item.message here -->
</ul>
</div>
</body>
</html>
updated
Based on your comment, to read any data of the parent element, use .closest().
Just read the text of <a> button and append it to the dialog. I used div #msg for demo purposes.
Demo
$('#list').on('click', 'li a', function () {
var text = $(this).closest('li').attr('data-name');
$('#msg').empty();
$('#msg').append(text);
$.mobile.changePage("#dialog", {
role: "dialog"
});
});

jQuery Mobile: data-rel="back" + data-transition does not work?

I created a jsfiddle that enables tabs using the navbar without changing the url hash: http://jsfiddle.net/ryanhaney/eLENj/
1) If I click on the "page 1" link from the home page, followed by clicking the "back" button, I get the reverse slide animation as expected.
2) If I click on the "page 1" link from the home page, then click on "page 2" or "page 3" (in the footer navbar), then click on the "back" button....there is no transition.
If I follow scenario #2 after changing the "$.mobile.changePage" call in the jsfiddle javascript to use a transition other than "none", the back button uses that same transition.
How can I enforce the transition for elements with data-rel="back"?
NOTE: In the jsfiddle example, it is desired behavior to keep tab selections out of the navigation history. The back button should go back home regardless of which tab you are on. There should be no transition between tabs. The jsfiddle example already provides this behavior.
I think I got it:
http://jsfiddle.net/E86M9/3/
Had to reset the changePage default transition value
$("a[data-role=tab]").each(function () {
var anchor = $(this);
anchor.bind("click", function () {
$.mobile.changePage(anchor.attr("href"), {
transition: "none",
changeHash: false
});
return false;
});
});
$("div[data-role=page]").bind("pagebeforeshow", function (e, data) {
$.mobile.silentScroll(0);
$.mobile.changePage.defaults.transition = 'slide'; // reset default here
});​

anchor.bind("click", function () {
$.mobile.changePage(anchor.attr("href"), {

return false;
Seems to be the issue with "transition: "none",". When I remove it or change it to anything, it works as you expect it: http://jsfiddle.net/PQsyP/
