When I press the browser back button, my dialog shows again. How can I prevent this?
Html
<body>
<div data-role="page" id="page1">
click me
....stuff...
</div>
<div data-dialog="true" data-role="dialog" id="dialog">
go to p2
....stuff...
</div>
<div data-role="page" id="page2">
....stuff...
</div>
</body>
Model:
function UserViewModel() {
self.startEvacuation = function () {
$.mobile.navigate("#page2");
}
};

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.
JQM AJAX navigation doesn't work well when navigating to a page with an in-page dialog?
page1.aspx:
<div data-role="page">
<div data-role="header">Page 1</div>
<div data-role="content">
<a href='page2.aspx'>Click here</a>
</div>
</div>
page2.aspx:
<div data-role="page">
<div data-role="header">Page 2</div>
<div data-role="content">
Popup
</div>
</div>
<div data-role="dialog" id='popup'> <!-- This is not loaded on AJAX navigation -->
<div data-role="header">Page 2 Popup</div>
<div data-role="content">
Popup content
</div>
</div>
When you click the link from Page 1, it doesn't load the <div data-role='dialog'> of Page 2.
How do you get around this issue?
There is a workaround here. I modified it a little:
$(document).bind('pagecontainerload', function (event, ui) {
// Find all dialogs in the DOM
var response = ui.xhr.responseText;
var data = $(response).find("div[data-role='dialog'],div[data-role='popup']");
for (var i = 0; i < data.length; i++) {
var node = data.eq(i);
if (node.attr('id') && document.getElementById(node.attr('id')))
$('#' + node.attr('id')).remove(); // Delete existing one
node.addClass('cache').appendTo('#form1'); // or appendTo('body')
}
});
I added the class cache for cleanup purpose.
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 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>

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"
});
});
