I am using jquery mobile and a dialog to display some multiple select boxes. Some of the content is dynamically created with Ajax based on the selections. I would like to make the Ajax call when the dialog is closed (through the regular x button). The main parts of the html look as follows:
<a href="#queryPage" data-rel="dialog" data-transition="slidedown" >Filter Results</a>
<div data-role="page" id="queryPage" data-theme="a">
<div data-role="header" data-theme="a">
<h1>Select Filters</h1>
</div>
<div data-role="content">
<form action="" method="get" id="filterForm">
<fieldset id ="filterFields"></fieldset>
</form>
</div>
</div>
I am currently making the call by running the code on page hide as follows:
$('#queryPage').live('pagehide', function(event) {
//code for ajax call
});
However, I would like to make the call when the dialog closes because some of the select lists are large and they create a new page that hides the queryPage even though the dialog has not been closed. I have tried:
$('#queryPage').bind('dialogclose', function(event) {
alert('closed');
});
and also tried
$('#queryPage').dialog({close:function(event, ui){
alert("closed");
}});
These I have put in a function called on page load but the alert is not shown when the dialog is closed. Any help will be appreciated.
There are no specific events for dialogs as they are simply pages that are displayed as a dialog. Try the pagehide event.
$("#MyDialog").bind("pagehide",function(){
alert("Dialog closed");
});
Also, the first line of your sample code has a link that is outside of a <div data-role="page"> which should not be done.
Pagehide can be delegated as such:
$(document).delegate("#MyDialog", "pagehide", function() {
alert("Dialog closed");
});
and you will also have access to the screen elements of the calling page.
Andleer shared the appropriate event for closing the dialog using jquery. however, we can also code in this way.
$(document).on("pagehide","#Dialog",function(){
console.log('Dialog has closed.');
});

I have a jQuery UI dialog with several tabs, sometimes, I need to pop up one of those tabs as a separate dialog (atop of tabbed initial dialog), so, can I achieve this by re-using the same dialog?
(of course with a bit run-time customizations, JavaScript/DOM HTML manipulations, but with the same <div></div> template initially defined and with the same HTML FORM elements IDs)
This is not the optimal solution, but could be an approach of what should you do.
HTML:
<div id="dialog" title="Basic dialog">
<div class="dtabs">
<ul>
<li>First
</li>
<li>Second
</li>
<li>Third
</li>
</ul>
<div id="tab1">
<p>First!</p>
</div>
<div id="tab2">
<p>Second!</p>
</div>
<div id="tab3">
<p>Third!</p>
</div>
</div>
</div>
<input value="Tab 1 on Dialog" type="button" alt="1" />
<input value="Tab 2 on Dialog" type="button" alt="2" />
<input value="Tab 3 on Dialog" type="button" alt="3" />
Javascript:
$(function () {
// Dialog without autoOpen just to hide it from viewport
$('#dialog').dialog({
autoOpen: false
});
$('input').click(function () {
// Clone the dialog and append it to body
// Get "tab" number to know which tab should I set as active later
var d = $('#dialog').clone().appendTo('body'),
tab = $(this).attr('alt')-1;
// Assign "dialog" behaviour and remove it when I close it
d.dialog({
autoOpen: false,
close: function (e, ui) {
$(this).dialog('destroy').remove();
}
});
// Tabs inside my dialog has "tabs" behaviour by JQueryUI
d.find('.dtabs').tabs({
active: tab
});
// Open up!
d.dialog('open');
});
});
http://jsfiddle.net/franverona/k7cuH/
Let me explain you what I did:
I create my dialog in pure HTML and using JQueryUI assign it a dialog behaviour.
Every button has a property that will tell me later what tab should I open in my future dialog.
When user click on button I clone my previous dialog, append it to body and get "tab" attribute. Then I assign it a dialog behaviour without autoOpen and with a function associated to close event to remove it from DOM (to avoid multiple dialogs on my HTML body).
Before open, I assign a tabs behaviour to all the content inside my recently created dialog (look that I'm using find function) and set as an active tab the correct tab using tab property retrieved before.
Now I'm ready to open my dialog with all set up.
I repeat: this isn't an optimal solution, but should work as a prototype of later development iterations.
Happy coding!
I'm using jQuery Mobile + Backbone + RequireJS. After successful login I do the following:
require(['app/view/main'], function(MainView) {
var mainView = new MainView();
$('body').html(mainView.render().el);
});
and render() looks like
render: function() {
this.$el.html(this.template);
return this;
}
Upon doing so, my page is blank. Inspecting the body, I do see the following HTML inside the body:
<div data-role="page" id="main">
<div data-role="header" data-position="inline">
<h1>Accounts</h1>
</div>
<div data-role="content">
hello
</div>
</div>
I've also tried doing this inside render():
this.$el.html(this.template).trigger('create');
as well as
this.$el.html(this.template).page();
but the page is still blank. Any ideas why?
If I simply put the HTML inside the body and load the page, it displays fine, like a normal jQuery Mobile app would.
Are you waiting until after pageinit to trigger / create your page?
$(document).bind('pageinit', function() {
// trigger
});
Also, jQM may be interpreting your markup as a single page template and then by injecting a data-role='page' element, you are marking up a multiple page document (with only a single page). Try leaving the <div data-role='page'> element in your default markup and then dynamically add the header, content and footer. jQM should then correctly interprete the markup and enhance it accordingly.
I am trying to programmatically click a link in jQuery Mobile but its not working. Here is the page code.
<section id="welcome" data-role="page">
<div class="content" data-role="content">
<a id="myLink" href="http://www.google.de" target="_blank">The link</a>
<input type="button" id="launcher" value="Launch the link"/>
</div>
</section>
and here is the correpsonding javascript code:
$(document).ready(function()
{
$("#launcher").bind("click",function()
{
console.log("Inside the button click handler");
$("#myLink").click();
});
});
Seems straightforward enough but I can,t seem to make it work.Any help is appreciated.
A possible reason for it not working is that there is another <a id="myLink"></a> in the DOM, but not in the active page. If that is the case, your code might be triggering the click handler on that element rather than the one you see on screen. Maybe using $.mobile.activePage.find("#myLink").click(); will work.
Also, you should avoid using $(document).ready() in jQuery Mobile.
Not really an answer to the question,but this can be a solution if you want to achieve only the link to be launched(and you dont want to execute the click handler you have defined for the link,if any)
$(document).ready(function()
{
$("#launcher").bind("click",function()
{
console.log("Inside the button click handler");
window.open($("#myLink").attr("href"),$("#myLink").attr("target"));
});
});
You should use a trigger, like so:
$('#mylink').trigger('click');
also, check your binding is actually being bound to an element. In JQM you should not rely on $(document).ready. Instead use $(document).bind('pageinit') . See here
I had the same problem.
What worked for me was calling click() on the DOM object itself. Just add ”[0]” after the jQuery object.
Like this:
$(document).ready(function()
{
$("#launcher").bind("click",function()
{
console.log("Inside the button click handler");
$("#myLink")[0].click();
});
});
Behold: a footer template:
<!-- Templates -->
<script type="text/template" id="templateFooter">
<div data-role="navbar">
<ul>
<li>About</li>
<li>Contact</li>
</ul>
</div>
</script>
In every mobile page I have:
<div data-role="footer" data-position="fixed">footer</div>
The way I'm currently loading the template is:
$(function() {
$('div[data-role=footer]').html($('#templateFooter').html());
$.mobile.activePage.trigger('create');
});
This works, but I don't really like using $(function(), but I need to load it if any page shows, so pageinit or pageshow does not help. I'll be using knockout.js going forward, if that is of any help.
Is there a better way to do this?
function getTemplateFooter() {
//return footer text here
}
$("div:jqmData(role='page')").live("pagebeforecreate",function() {
// get the footer of the page
// if footer doesn't exist on page, insert it where you want it... in this case after role="content"?
var $content =$(this).page().find('div:jqmData(role="content")');
$content.after(getTemplateFooter());
}
there is also a pageshow event, that one fires even if the user navigates to the page, through a back button press etc... it bubbles up to the page div
I use it for pages where lots of dynamic data could change between subsequent visits, or even when the user just presses back
I am tryng to use this: http://jqueryui.com/demos/dialog/#modal-form
I have:
<script type="text/javascript">
$(document).ready(function() {
$("#dialog").dialog();
$("#dialog").dialog('close');
$('.myPop').click(function() {
$("#dialog").dialog('open');
});
});
Which allows me to pop-up on the click of '.myPop' which is just a temp input button in my list which is working:
<button type="button" class="myPop"></button>
My question is - what is the best way to use this pop-up to go to the Edit method of my controller, populate controls and then be able to save back to the model and refresh the list page?
I want to keep with best practice in ASP.Net MVC please.
Am I beetr maybe using this? http://dev.iceburg.net/jquery/jqModal/
Thanks
There's obviously a bunch of ways to do that, but here's how I would solve it. Perform an ajax call before loading the dialog to populate the dialog's contents, show the dialog, than on save close the dialog and refresh the grid. Those are the basics, there's some helper code below. I find it a good practice to return a json result from the save action to determine if the saved was successful, and if not an error message that indicates why it failed to display to the user.
<div id="dialog" title="Basic dialog">
<!-- loaded from ajax call -->
<form id="exampleForm">
<input blah>
<input type="button" onclick="Save()" />
</form>
</div>
<script>
$(function() {
$('.myPop').click(function() {
$.get("editController/loadContents", function(data){
$("#dialog").html(data);
});
$("#dialog").dialog('open');
});
});
function Save(){
$.post("/editController/Edit", $("#exampleForm").serialize(),
function(data){
$("#dialog").dialog('close');
//update grid with ajax call
});
}
</script>
