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 });
}
});

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
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.
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
another problem I have faced is that when I back from Page1 to the home Page the Home Page links become not working I click the Page1 link but Page1 didn't open, even if i click on the link many times it didn't open Page1 .. How can i solve this problem also ?? Please help me

I think it should be what you're wanting:
<div data-role="page" id="index">
<div data-role="panel" id="mypanel">
Jump to index page
Jump to second page
Jump to third page
</div>
<div data-theme="a" data-role="header">
<h3 id="header-page">
First Page
</h3>
</div>
<div data-role="content" id="content-page">
<a data-role="button" href="#mypanel">Open Pannel</a>
</div>
<div data-theme="a" data-role="footer" data-position="fixed" id="footer-page">
.
</div>
</div>
<div class="soHide" id="index">
<div data-theme="a" data-role="header">
<h3 id="header-index">
First Page
</h3>
</div>
<div data-role="content" id="content-index">
<a data-role="button" href="#mypanel">Open Pannel</a>
</div>
<div data-theme="a" data-role="footer" data-position="fixed" id="footer-index">
.
</div>
</div>
<div class="soHide" id="second">
<div data-theme="a" data-role="header">
<h3 id="header-second">
Second Page
</h3>
</div>
<div data-role="content" id="content-second">
<p>this is a second page</p>
<a data-role="button" href="#mypanel">Open Pannel again</a>
</div>
<div data-theme="a" data-role="footer" data-position="fixed" id="footer-second">
footer second page
</div>
</div>
<div class="soHide" id="third">
<div data-theme="a" data-role="header">
<h3 id="header-third">Third Page</h3>
</div>
<div data-role="content" id="content-third">
<a data-role="button" id="open-panel">Open Pannel one more time</a>
<p>it's third!</p>
</div>
<div data-theme="a" data-role="footer" data-position="fixed" id="footer-third">
it's some third footer page
</div>
</div>
and this javascript:
$(document).on('click', '.btnPages', function(){
var page = $(this).attr('data-idpage');
var header = $("#header-"+page).html();
var content = $("#content-"+page).html();
var footer = $("#footer-"+page).html();
// apply
$("#header-page").html(header).trigger('create');
$("#content-page").html(content).trigger('create');
$("#footer-page").html(footer).trigger('create');
});
and this css:
.ui-panel-animate {
transition: transform 1350ms ease 0s !important;
}
.soHide { display: none; }
and this functional example http://jsfiddle.net/wgbn/Hxy37/
I have a backbone app using jquery mobile. I am trying to use a dialog popup however the problem is when i click the link #popupSuccess it doesn't activate the modal because i assume backbone is trapping it. Any ideas?
This is my modal code
<a class="modalLink" id="modalSuccessTrigger" href="#popupSuccess" data-rel="popup" data-position-to="window" data-role="button" data-inline="true" data-transition="pop" data-icon="delete" data-theme="b">Success</a>
<div data-role="popup" id="popupSuccess" data-overlay-theme="a" data-theme="c" data-dismissible="false" style="max-width:400px;" class="ui-corner-all modalLinkCont">
<div data-role="header" data-theme="a" class="ui-corner-top">
<h1>Correct!</h1>
</div>
<div data-role="content" data-theme="d" class="ui-corner-bottom ui-content" style="background-color:white">
<h3 class="ui-title">That is correct. Tap to continue to level 2</h3>
Contineu
</div>
</div>
You need to programmatically initiate the popup:
In your backbone view:
events: {
'click #modalSuccessTrigger': 'openPopUp'
},
openPopUp: function(e) {
e.preventDefault()
$('#modalSuccessTrigger').popup('open')
}
for more details refer to doc: http://jquerymobile.com/demos/1.2.0-alpha.1/docs/pages/popup/index.html
To handle this issue I use to prevent the backbone routing and activate the popup handling for links marked as data-rel="popup"
$(document).ready(function(){
($('a[data-rel="popup"]')).on('click', function(event) {
event.preventDefault();
event.stopImmediatePropagation();
var target = $(this).attr("href");
$(target).popup('open');
});
});
