formDiv.dialog is not a function [duplicate]

I am having an issue getting a dialog to work as basic functionality. Here is my jQuery source imports:
<script type="text/javascript" src="scripts/jquery-1.9.1.js"></script>
<script type="text/javascript" src="scripts/jquery-ui-1.11.1.js"></script>
<script type="text/javascript" src="scripts/json.debug.js"></script>
Html:
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>
<script type="text/javascript">
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
</script>
From the posts around seems like as a library import issue. I downloaded the JQuery UI Core, Widget, Mouse and Position dependencies.
Any Ideas?

Be sure to insert full version of jQuery UI. Also you should init the dialog first:
$(function () {
$( "#dialog1" ).dialog({
autoOpen: false
});
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css" />
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>

if some reason two versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
Some times it could be issue with older version (or not stable version) of JQuery files
Solution use $.noConflict();
<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
// Code that uses other library's $ can follow here.
</script>

If you comment out the following code from the _Layout.cshtml page, the modal popup will start working:
</footer>
#*#Scripts.Render("~/bundles/jquery")*#
#RenderSection("scripts", required: false)
</body>
</html>

Change jQueryUI to version 1.11.4 and make sure jQuery is not added twice.

I just experienced this with the line:
$('<div id="editor" />').dialogelfinder({
I got the error "dialogelfinder is not a function" because another component was inserting a call to load an older version of JQuery (1.7.2) after the newer version was loaded.
As soon as I commented out the second load, the error went away.

Here are the complete list of scripts required to get rid of this problem.
(Make sure the file exists at the given file path)
<script src="#Url.Content("~/Scripts/jquery-1.8.2.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery-ui-1.8.24.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript">
</script>
and also include the below css link in _Layout.cshtml for a stylish popup.
<link rel="stylesheet" type="text/css" href="../../Content/themes/base/jquery-ui.css" />

I had a similar problem and in my case, the issue was different (I am using Django templates).
The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.
I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.

Use of jquery noconflict function when including external js libraries and js code files

Does one need to use jquery noconflict() method in the following
situation.
`<script type="text/javascript" src="jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="jq180customcode.js"></script>
<script type="text/javascript" src="jquery-1.7.1.min.js"></script><script type="text/javascript" src="jq171customcode.js"></script>`
The above situation is when we use different jquery libraries in a
single page and load external files with custom code specific to the
the library mentioned above it.
If one does need to use the jquery noconflict method please show how to
use it.
Here jq180customcode and jq171customcode external javascript files contains script functions which are written keeping in mind the external libraries jq-1.8.0 and jq-1.7.1 libraries respectively that is "jq180customcode.js" contains functions specific for the html page which are created in accordance with "jq-1.8.0.js" and "jq171customcode.js" contains functions specific for the html page which are created in accordance with "jq-1.7.1.js". I specifically want to know whether one needs to use jquery.noconflict in these "customcode" files and if one has to use it how?

A much better solution is not to use multiple copies of jQuery on the same page. Just use one. Ideally something more recent than either of those.
But if you really want to:
<script type="text/javascript" src="jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="jq180customcode.js"></script>
<script>
var jq180 = jQuery.noConflict(true);
</script>
<script type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="jq171customcode.js"></script>
<script>
var jq171 = jQuery.noConflict(true);
</script>
Note that it's important that jq180customcode.js grab a copy of the jQuery and/or $ symbol right away and store it. One good way is like this:
(function($) {
// The code here
})(jQuery);
Within The code here, the code can use $ to refer to the jQuery that was present when the code was loaded.
In scripts after all of the above, you'd use jq180 or jq171 depending on which copy of jQuery you want to use.
You could leave one or the other noConflict off, of course, and use jQuery (and $) for the other one. For instance (reordering things slightly):
<script type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="jq171customcode.js"></script>
<script>
var jq171 = jQuery.noConflict(true);
</script>
<script type="text/javascript" src="jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="jq180customcode.js"></script>
Now, you'd use jq171 for jQuery v1.7.1 and either jQuery or $ for jQuery v1.8.0.
Here's a live example of using v1.7.1 and v1.8.0:
<input id="btn1" type="button" value="Click to see jQuery v1.8.0 in use">
<br><input id="btn2" type="button" value="Click to see jQuery v1.7.1 in use">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<script>
// Custom v1.8.0 stuff
(function($) {
$("#btn1").click(function() {
$("<p>jQuery version: " + $.fn.jquery + "</p>").appendTo(document.body);
});
})(jQuery);
</script>
<script>
var jq180 = jQuery.noConflict(true);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
// Custom v1.7.1 stuff
(function($) {
$("#btn2").click(function() {
$("<p>jQuery version: " + $.fn.jquery + "</p>").appendTo(document.body);
});
})(jQuery);
</script>
<script>
var jq171 = jQuery.noConflict(true);
</script>

How do I make this JavaScript work on my local machine?

The code I have below works if it's on my server but when viewed on my local machine it gives me the following errors:
ReferenceError: jQuery is not defined
$(document).ready(function() {
default.html (line 24)
ReferenceError: $ is not defined
$(document).ready(function() {
default.html (line 12)
ReferenceError: $ is not defined
$(document).ready(function() {
CODE:
<script src="//code.jquery.com/jquery-latest.min.js"></script>
<link rel="stylesheet" href="slider/site/style.css">
<script type="text/javascript" src="slider/src/unslider.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var unslider = $('.container').unslider();
$('.arrow').click(function() {
var fn = this.className.split(' ')[1];
// Either do unslider.data('unslider').next() or .prev() depending on the className
unslider.data('unslider')[fn]();
});
});
</script>
<script type="text/javascript">
$(document).ready(function() {
$('.line1').fadeIn(7000);
$('#slide2').delay(1000).fadeIn(3200);
$('#slide3').delay(1800).fadeIn(3200);
$('.line4').delay(4000).fadeIn(3500);
});
</script>

Your script tag is probably giving your browser trouble. Replace "//code.jquery.com/jquery-latest.min.js" with "http://code.jquery.com/jquery-latest.min.js" and it should then work.

Replace
<script src="//code.jquery.com/jquery-latest.min.js"></script>
with
<script src="code.jquery.com/jquery-latest.min.js"></script>
Your code couldn't find jquery.

Add http to
<script src="http://code.jquery.com/jquery-latest.min.js"></script>

this will do the trick
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
//code.jquery.com/jquery-latest.min.js this is pointing to find jQuery in the local server but the script is not available in the local server so chnage this to http://code.jquery.com/jquery-latest.min.js"

You could have also downloaded the latest version and placed it in a js folder under your docroot. Then you could have accessed it with:
<script src="js/jquery-latest.min.js"></script>

jQuery, IE 7 Object doesn't support this property or method

I'm including some lines of Javascript code in a Drupal page with input format as full html.
The script works perfectly in Firefox and Chrome, but IE (7) fails with
'Object doesn't support this property
or method'
this is the exact code I'm inserting in the Drupal page:
<link rel="stylesheet" href="/scripts/gallery/jquery-1.6.1/css/slimbox2.css" type="text/css" media="screen" />
<script type="application/javascript" src="/scripts/gallery/jquery-1.6.1/jquery-1.6.1.js">
<script type="application/javascript" src="/scripts/gallery/jquery-1.6.1/slimbox2.js">
<script type="application/javascript" src="/scripts/gallery/jquery-1.6.1/jquery.EmbedPicasaGallery.js">
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery.noConflict();
jQuery("#pics").EmbedPicasaGallery('mygallery',{
matcher: /./,
loading_animation: 'css/loading.gif',
msg_back : 'Back',
size: '85'
});
});
</script>
<div id="pics" />
The javascript error occurrs on this line, at char 2:
jQuery("#pics").EmbedPicasaGallery('mygallery',{
This probably is not a very orthodox way of including a custom javascript in a Drupal page.
How should I do it, and how can I make it work with IE?

I'd suggest transferring the .noConflict() call right after the <script> tag for jQuery, and switching application/javascript to text/javascript (though I'm not really sure about application/javascript --- just never used it before).
<script type="text/javascript" src="/scripts/gallery/jquery-1.6.1/jquery-1.6.1.js">
<script type='text/javascript'>jQuery.noConflict();</script>
<script type="text/javascript" src="/scripts/gallery/jquery-1.6.1/slimbox2.js">
<script type="text/javascript" src="/scripts/gallery/jquery-1.6.1/jquery.EmbedPicasaGallery.js">
<script type='text/javascript'>
jQuery(function($) {
$('#pics').EmbedPicasaGallery({
// blah
});
});
</script>
Also, you may want to double check your matcher variable in the JSON object you pass in. I'm assuming that might be a string you're passing in, so you might have to pass that in as matcher : '/./'.

JQuery Slideshow and MooTools Conflict

I am having a problem with the motools library conflicting with my jQuery library:
Here's the code:
<script language="Javascript" type="text/javascript" src="revamp/js/jquery-1.4.2.js"></script>
<script language="Javascript" type="text/javascript" src="revamp/js/jquery.blinds-0.9.js"></script>
<script type="text/javascript" src="js/mootools-1.2-core.js"></script>
<script type="text/javascript" src="js/_class.viewer.js"></script>
<script type="text/javascript">//<![CDATA[
window.addEvent('domready',function(){
var V5 = new viewer($('boxCont').getChildren(),{
mode: 'alpha',
fxOptions: {duration:500},
interval: 6000
});
V5.play(true);
});
</script>
<script type="text/javascript">
$(window).load(function () {
// start the slideshow
$('.slideshow').blinds();
})
</script>
If I disable mootools, the slideshow work (vice versa with the jQuery). I tried wrapping the jQuery around jQuery.noConflict(); like so:
<script type="text/javascript">
$.noConflict();
jQuery(document).ready(function($) {
$(window).load(function () {
// start the slideshow
$('.slideshow').blinds();
})
});
</script>
But still the mootools dependent script doesn't work. Please help as I'm not really familiar with jQuery/javascript.
Thanks!

Once you call jQuery.noConflict(), you refer to jQuery via jQuery rather than $. $ is then usable by MooTools or another JavaScript library.
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function() {
jQuery(window).load(function () {
// start the slideshow
jQuery('.slideshow').blinds();
})
});
</script>
If you want to give jQuery another name, you can do the following:
<script type="text/javascript">
var jq = jQuery.noConflict();
jq(document).ready(function() {
jq(window).load(function () {
// start the slideshow
jq('.slideshow').blinds();
})
});
</script>

You want jQuery.noConflict().
But you don't really need to, because you are using jQuery for your jQuery alias, and you are passing $ as the argument which maps to the jQuery object.
So long as all your jQuery (and jQuery only) happens inside that jQuery(document).ready(), then you can use $ for jQuery and not worry about about clashes.
