I am trying to get jQuery.post() to run my php script and then open a jQuery UI dialog with the data that php script returns. Its supposed to come back as a form with a table and a textarea in it. It works great with alert(data); and i get a pop-up with all my data.
The problem starts if i turn off alert(). Now it opens 2 dialogs. One containing only the table, without textarea, and the second one absolutely empty.
What am i doing wrong here? How come all my data shows up in the alert(), but not in dialog? What do i need to do to fix it?
Oh, and do i need to also include $.ajax() before the $.post()?
Thank you.
$.post("/path/to/script.php",
{ id: this.id, value: value },
function(data){
// THIS WORKS
//alert(data);
// THIS DOES NOT WORK
$(data).dialog({
autoOpen: true,
width: 400,
modal: true,
position: 'center',
resizable: false,
draggable: true,
title: 'Pending Changes'
});
}
);
You don't need another $.ajax() call. The $.post() method is a wrapper shortcut to $.ajax(). What might be happening is you may be getting both default behavior and Javascript bound behavior. I'm assuming this $.post action triggered on a click. If so, then at the very end of your $.click() handler you need to return false to prevent default behavior.
$('input[type=submit]').click(function() {
$.post( /* ... */ );
return false;
});
This is how I handle it. I have a empty div and initialize the dialog upon document ready. Now on the ajax return load that div's html with the data received from PHP and call the "open" method of dialog. Simple and definitely works.
HTH
Ah! This was not a problem with the JS, but my php file.
The textarea was sitting outside of <div>blah blah</div>.
Problem solved.

I have been trying to implement the autocomplete and have come across a problem that has stumped me. The first time I call .autocomplete it all works fine and I have no problems. If, however, I call it after I have removed some (unrelated) elements from the DOM and added a new section to the DOM then autocomplete does nothing and reports no errors.
Code:-
$.ajax({
type : 'get',
dataType : 'json',
url : '/finance/occupations',
cache:true,
success:function(data){
occupationList = data;
$('.js-occupation').autocomplete({
source: occupationList,
messages: {
noResults: '',
results: function(){}
},
minLength : 2,
select:function(event, ui){
$('.js-occupationId').val(ui.item.id);
}
});
}
});
The background to this page is that it contains multiple sections that are manipulated as the user moves through them. Hide and show works fine and does not impact on the autocomplete. However, if I do the following:-
var section = $('.js-addressForm:last').clone();
clearForm(section);
$('div.addressDetails').append(section);
$('.js-addressForm:first').remove();
Which gives the user the bility to add multiple addresses on the previous section then the autocomplete stops working.
Any suggestions or pointers on something obvious I am missing?
I have tried to put the initialisation of the autocomplete on an event when the element gets focus and it still does not work.
You have to create the autocomplete after all other underlying objects. If you F12, you will see that the list is "visible", however it is below and hidden by all instances created after it.
If you created a div with inputs (one input being the autocomplete), then you create the automplete then the dialog instances, the autocomplete will never show. If you create the dialog then the autocomplete, no problem. The problem is the z-order
I have faced the same issue. For now to fix this, i'm creating widget on the input once input is in focus. It will help you solve the issue.
You can look for the help on
making sure some event bing only when needed
Sample code will look like this
$( "#target" ).focus(function() {
//I don't care if you manipulated the DOM or not. I'll be cautious. ;)
(function() {
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
})();
// use a flag variable if you want
});
This solved my problem. Hope its the solution you were looking f
I'm using jQueryUI to create a dialog, I want the dialog object to be destroyed when it's removed.
So I did something like this:
thisDialog.dialog({
autoOpen: true,
close: function(event, ui) {
thisDialog.dialog("destroy");
}
});
What I want to do is maintain the existence of the element that thisDialog is attached to, but simply destroy the jQueryUI .dialog() object that is attached to it, not change my DOM.
Sample:
http://jsfiddle.net/ytWPV/1/
Update:
This may be a bug/issue with jQueryUI? If someone can show that, I'll accept that as an answer as well
I am not sure what you want to accomplish with "destroy" versus "close", but I will assume you have good reasons.
If you can successfully close your dialog (essentially setting the entire DIV that represents your dialog to the CSS equivalent of display:none) but want to go further and have the html more permanently removed from the DOM, I would add some logic to the close function that would use a selector (any selector will suffice) to find the top-most DIV for your dialog and then to manually set the .html() for that DIV to and empty string. That will basically wipe out the internal HTML and leave you with only your original that once acted as a dialog...
You could also try cloning the element if it doesn't change such as:
$("#win2").clone().attr("id","random").dialog({
autoOpen: true,
height: 60,
width: 50,
modal: true,
close: function(event, ui) {
alert($(".hide").html())
this.dialog("destroy");
}
});
...which the original code came from your example.
I want to set the overlay of a jQuery dialog to an image, and can't seem to manage the task.
I have other dialogs on the pages that I want to no have the background images, so setting the css for the overlay background won't work as a blanket solution.
I have tried a lot of different methods, and I believe there is a timing issue with the appliction of the jQuery command to set the overlay with css and the actual dialog div's and css getting added to the DOM.
Here is what I have tried so far.
$('#submitUpload').click(function(){
$("#uploadStart").dialog('open');
$(".ui-widget-overlay").css({'background-image': 'url("http://www.mydomain.com/images/ftp-page-bg.gif")','opacity':'1'})
$("#uploadForm").submit();
});
OR
$("#uploadStart").dialog({
autoOpen: false,
width: 400,
modal: true,
closeOnEscape: false,
draggable: false,
resizable: false,
open: function(event, ui) {
$(".ui-dialog-titlebar-close").hide();
$(".ui-widget-overlay").css({'background-image': 'url("http://www.mydomain.com/images/ftp-page-bg.gif")','opacity':'1'})
}
});
I have also tried using the dialogClass method on the dialog code with no success.
With both the absolute url and the relative, and the url in quotes or with no quotes.
The image exists in the directory.
Anyone have any ideas on how to get jQuery to apply with the correct timing to display the image as the overlay?
Thanks!
Update
The dialog class designation will allow you to set classes for the overal dialog. I was actually looking to just tap into the specific ui-widget-overlay class and over-ride the background image there. I found that trying to override the background using the dialogClass worked for overriding the background of the dialog, not the overlay background.
When the dialog is added to the DOM, jQuery loads it's div's right before the body tag.
I found a solution, being that in the open method for the dialog, I used
$(".ui-widget-overlay").addClass('artFTP');
to add a class
.artFTP{background-image: url(../../images/ftp-page-bg.gif); opacity:1;}
and made sure it was the last class in the file that would overwrite the overlay background image.
I hope this helps someone.
Thanks and +1 to jjross, your answer got me to jump back into the jQuery docs.
If anyone has a better solution, please post. I would be happy to see it. I think there might be a way to use CSS to accomplish the task, but (for the life of me) couldn't figure it out.
You should be able to add the class to the div in your HTML code prior to jquery being called on it. In my testing, this automatically added that class to the dialog when it was created.
In the new class, you should be able to specify a background image.
For example:
calling:
$("#dialog").dialog();
on
<div id="dialog" class="thisClass" title="Edit Case Status">
<div>some stuff</div>
</div>
causes the dialog to be created with the
"thisClass" class.
as an alternative option, it looks like the dialog has a "dialogClass" method. It will let you add your own class to the dialog (in that class, you can define the background). From the docs:
The specified class name(s) will be added to the dialog, for additional theming.
Code examples
Initialize a dialog with the dialogClass option specified.
$( ".selector" ).dialog({ dialogClass: 'alert' });
Get or set the dialogClass option, after init.
//getter
var dialogClass = $( ".selector" ).dialog( "option", "dialogClass" );
//setter
$( ".selector" ).dialog( "option", "dialogClass", 'alert' );
I encountered the same problem and found In this case your question. I didn't find any solution that could satisfy me, so I did something on my own.
First, let me introduce my problem.
I have a page, where I have two kinds of dialogs. Dialogs with video and dialogs with message (like alert, confirmation, error etc.). As we know, we can set a different class for a dialog, but we can't set class for different overlay. So question was, how to set a different behavior for different overlays?
So I dig, I dig deeper than Dwarves in Moria into jQuery ui code itself. I found out, that actualy there is an unique overlay for each dialog. And it is created in "private" function _createOverlay which is not accessible. In fact, I found function via jquery ui namespace as $.ui.dialog.prototype._createOverlay. So I was able to make a small extension with logic based on class:
(function() {
// memorize old function
var originFn = $.ui.dialog.prototype._createOverlay;
// make new function
$.ui.dialog.prototype._createOverlay = function() {
originFn.call(this); // call old one
// write your own extension code there
if (this.options["dialogClass"] === "video-dialog") {
var overlay = this.overlay; // memorize overlay (it is in old function call as this.overlay)
var that = this; // just cause bind is event
// my own extenstion, when you click anywhere on overlay, dialog is closed + I change css
overlay.bind('click', function() {
that.close(); // it is same like element.dialog('close');
}).css({
"background": "none",
"background-image": "url(\'files/main-page/profile1.png\')" // this didnt work for you, but works for me... maybe I have newer version of jQuery.UI
// anyway, once you have overlay as variable, Im sure you will be able to change its css
});
}
};
})();
I hope this will help others :)
I've searched everywhere, but I can't seem to find any help...
I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option.
As an example, to bind all items with a class of .foo now and future created:
$('.foo').live('click', function(){
alert('clicked');
});
It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete...
This doesn't work:
$('.foo').live('autocomplete', function(event, ui){
source: 'url.php' // (surpressed other arguments)
});
How can I use .live() to bind autocomplete?
UPDATE
Figured it out with Framer:
$(function(){
$('.search').live('keyup.autocomplete', function(){
$(this).autocomplete({
source : 'url.php'
});
});
});
jQuery UI autocomplete function automatically adds the class "ui-autocomplete-input" to the element. I'd recommend live binding the element on focus without the "ui-autocomplete-input"
class to prevent re-binding on every keydown event within that element.
$(".foo:not(.ui-autocomplete-input)").live("focus", function (event) {
$(this).autocomplete(options);
});
Edit
My answer is now out of date since jQuery 1.7, see Nathan Strutz's comment for use with the new .on() syntax.
If you are using the jquery.ui.autocomplete.js try this instead
.bind("keydown.autocomplete") or .live("keydown.autocomplete")
if not, use the jquery.ui.autocomplete.js and see if it'll work
If that doesn't apply, I don't know how to help you bro
Just to add, you can use the .livequery plugin for this:
$('.foo').livequery(function() {
// This will fire for each matched element.
// It will also fire for any new elements added to the DOM.
$(this).autocomplete(options);
});
To get autocomplete working when loaded dynamically for the on() event used in jQuery > 1.7, using the syntax Nathan Strutz provides in his comment:
$(document).on('focus', '.my-field:not(.ui-autocomplete-input)', function (e) {
$(this).autocomplete(options)
});
where .my-field is a selector for your autocomplete input element.
.live() does not work with focus.
also keyup.autocmplete does not make any sense.
Instead the thing I have tried and working is this
$(document).ready(function(){
$('.search').live('keyup' , function()
{
$(this).autocomplete({ source : 'url.php' });
});
})
This works perfectly fine.
You can't. .live() only supports actual JavaScript events, not any custom event. This is a fundamental limitation of how .live() works.
You can try using this:
$('.foo').live('focus.autocomplete', function() {
$(this).autocomplete({...});
});
After reading and testing everyone else's answers I have updated it for the current version of JQuery and made a few tweaks.
The problem with using keydown as the event that calls .autocomplete() is that it fails to autocomplete for that first letter typed. Using focus is the better choice.
Another thing I have noticed is that all of the given solutions result in .autocomplete() being called multiple times. If you are adding an element dynamically to the page that will not be removed again, the event should only be fired once. Even if the item is to be removed and added again, the event should be removed and then added back each time the element is removed or added so that focusing on the field again will not unnecessarily call .autocomplete() every time.
My final code is as follows:
$(document).on('focus.autocomplete', '#myAutocomplete', function(e){
$(this).autocomplete(autocompleteOptions);
$(document).off('focus.autocomplete', '#myAutocomplete');
});
autocomplete is not an event rather a function that enables autocomplete functionality for a textbox.
So if you can modify the js that creates the textboxes dynamically to wrap the textbox element in as a jquery object and call autocomplete on that object.
I just noticed you edited your post with this answer. It was obvious to me so I'm posting it below for others. Thank you.
$(function()
{
$('.search').live('keyup.autocomplete', function()
{
$(this).autocomplete({ source : 'url.php' });
});
});
This works for me:
$(function()
{
$('.item_product').live('focus.autocomplete', function()
{
$(this).autocomplete("/source.php/", {
width: 550,
matchContains: true,
mustMatch: false,
selectFirst: false,
});
});
});
You can just put the autocomplete inside input live event, like this:
$('#input-element').live('input', function(){
$("#input-element").autocomplete(options);
});
I have a page that loads and after it loads, it pulls in a list of LIs to populate a news feed.
<li>quick view</li>
<li>quick view</li>
<li>quick view</li>
I'm trying to get fancy box to trigger when a user clicks on quick view but haven't had any luck. Any Ideas?
$(document).ready(function() {
$('.quickview').fancybox();
});
also tried:
$(document).ready(function() {
$('a.quickview').live('click', function() {
$(this).fancybox();
});
});
http://fancybox.net/
Thanks for any ideas...
Old question, but might be useful for future searchers.
My preferred solution is to fire fancybox manually from within the live event, eg:
$('.lightbox').live('click', function() {
$this = $(this);
$.fancybox({
height: '100%',
href: $this.attr('href'),
type: 'iframe',
width: '100%'
});
return false;
});
EDIT: From jQuery 1.7 live() is deprecated and on() should be used instead. See http://api.jquery.com/live/ for more info.
this should work after every ajax request
$(document).ajaxStop(function() {
$("#whatever").fancybox();
});
The problems is to attach fancybox into AJAX loaded element, right?
I got same problems and I found this solution.
I copy paste it here, see the original bug report for more info:
$.fn.fancybox = function(options) {
$(this)
.die('click.fb')
.live('click.fb', function(e) {
$(this).data('fancybox', $.extend({}, options, ($.metadata ? $(this).metadata() : {})))
e.preventDefault();
[...]

Since .on is now recommended over .live, and after reading over the documentation on delegated events, here's a solution I came up with (assuming your elements have a class of 'trigger-modal'):
$(document).on('click', '.trigger-modal', function() {
// remove the class to ensure this will only run once
$(this).removeClass('trigger-modal');
// now attach fancybox and click to open it
$(this).fancybox().click();
// prevent default action
return false;
});
From my understanding of Fancybox, the call to fancybox() simple attaches the plugin to the selected element. Calling fancybox on a click event won't open anything.
I think you just need to add
$(li_element_that_you_create).fancybox();
to the code that creates the new LI elements in your list
EDIT
If you're using load, then you would do something like:
$('#ul_id_goes_here').load('source/of/news.feed', function() {
$('.quickview').fancybox();
});
