I found a script which I want to use to my website. The problem is that this script is using jquery.tmpl which is messing some stuff on my site.
<script type="text/javascript" src="cameras/jquery.tmpl.js"></script>
I think it may be any conflict there with jQuery which I am using for some menus.
<script src="js/jquery-1.10.2.min.js"></script>
Is there anything I can do to fix that ?
Regards,
use noConflict();
<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
// Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>

A project I'm working on requires the use of jQuery on customers' Web pages. Customers will insert a chunk of code that we'll supply which includes a few <script> elements that build a widget in a <script>-created <iframe>. If they aren't already using the latest version of jQuery, this will also include (most likely) a <script> for Google's hosted version of jQuery.
The problem is that some customers may already have an older version of jQuery installed. While this may work if it's at least a fairly recent version, our code does rely on some recently introduced functionality in the jQuery library, so there are bound to be instances when a customer's jQuery version is just too old. We can't require that they upgrade to the latest version of jQuery.
Is there any way to load a newer version of jQuery to use only within the context of our code, that will not interfere with, or affect, any code on the customer's page? Ideally, maybe we could check for the presence of jQuery, detect the version, and if it's too old, then somehow load the most recent version just to use for our code.
I had the idea of loading jQuery in an <iframe> in the customer's domain that also includes our <script>, which seems like it might be feasible, but I'm hoping there's a more elegant way to do it (not to mention without the performance and complexity penalties of extra <iframe>s).
Yes, it's doable due to jQuery's noconflict mode. http://blog.nemikor.com/2009/10/03/using-multiple-versions-of-jquery/
<!-- load jQuery 1.1.3 -->
<script type="text/javascript" src="http://example.com/jquery-1.1.3.js"></script>
<script type="text/javascript">
var jQuery_1_1_3 = $.noConflict(true);
</script>
<!-- load jQuery 1.3.2 -->
<script type="text/javascript" src="http://example.com/jquery-1.3.2.js"></script>
<script type="text/javascript">
var jQuery_1_3_2 = $.noConflict(true);
</script>
Then, instead of $('#selector').function();, you'd do jQuery_1_3_2('#selector').function(); or jQuery_1_1_3('#selector').function();.
After looking at this and trying it out I found it actually didn't allow more than one instance of jquery to run at a time. After searching around I found that this did just the trick and was a whole lot less code.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script>var $j = jQuery.noConflict(true);</script>
<script>
$(document).ready(function(){
console.log($().jquery); // This prints v1.4.2
console.log($j().jquery); // This prints v1.9.1
});
</script>
So then adding the "j" after the "$" was all I needed to do.
$j(function() {
$j('.button-pro').on('click', function() {
var el = $('#cnt' + this.id.replace('btn', ''));
$j('#contentnew > div').not(el).animate({
height: "toggle",
opacity: "toggle"
}, 100).hide();
el.toggle();
});
});
Taken from http://forum.jquery.com/topic/multiple-versions-of-jquery-on-the-same-page:
Original page loads his "jquery.versionX.js" -- $ and jQuery belong to versionX.
You call your "jquery.versionY.js" -- now $ and jQuery belong to versionY, plus _$ and _jQuery belong to versionX.
my_jQuery = jQuery.noConflict(true); -- now $ and jQuery belong to versionX, _$ and _jQuery are probably null, and my_jQuery is versionY.
You can have as many different jQuery versions on your page as you want.
Use jQuery.noConflict():
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<script>
var $i = jQuery.noConflict();
alert($i.fn.jquery);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
var $j = jQuery.noConflict();
alert($j.fn.jquery);
</script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script>
var $k = jQuery.noConflict();
alert($k.fn.jquery);

It is possible to load the second version of the jQuery use it and then restore to the original or keep the second version if there was no jQuery loaded before. Here is an example:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
var jQueryTemp = jQuery.noConflict(true);
var jQueryOriginal = jQuery || jQueryTemp;
if (window.jQuery){
console.log('Original jQuery: ', jQuery.fn.jquery);
console.log('Second jQuery: ', jQueryTemp.fn.jquery);
}
window.jQuery = window.$ = jQueryTemp;
</script>
<script type="text/javascript">
console.log('Script using second: ', jQuery.fn.jquery);
</script>
<script type="text/javascript">
// Restore original jQuery:
window.jQuery = window.$ = jQueryOriginal;
console.log('Script using original or the only version: ', jQuery.fn.jquery);
</script>
I would like to say that you must always use jQuery latest or recent stable versions. However if you need to do some work with others versions then you can add that version and renamed the $ to some other name. For instance
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script>var $oldjQuery = $.noConflict(true);</script>
Look here if you write something using $ then you will get the latest version. But if you need to do anything with old then just use$oldjQuery instead of $.
Here is an example:
$(function(){console.log($.fn.jquery)});
$oldjQuery (function(){console.log($oldjQuery.fn.jquery)})
Demo
<script type="text/javascript"
src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>var $j = $.noConflict(true);</script>
It was not working for me then I changed it to
<script>var jQuery = $.noConflict(true);</script>
and it worked for me.
To further improve Juan Vidal's answer, it is worth noting that if you use multiple jquery plugins with one version (eg 3.3.1) and multiple jquery plugins with another version(eg 1.10.2), for older version to work (and it's plugins) you must dig into plugin's minified/unminified .js file(s) and alter the line that will be something like this:
Example 1: module.exports=a:a(jQuery) to module.exports=a:a(my_jQuery)
Example 2: b(a,require("jquery")):b(a,a.jQuery)} to this: or b(a,require("jquery")):b(a,a.my_jQuery)}

I'm looking for a jQuery noConflict example that shows 2 jQuery plugins in the same code snippet and how to use jQuery.noConflict so that these plugins should function. Where would it apply in the scenario below?
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="http://example.com/jquery.plugin_1.js"></script>
<script type="text/javascript" src="http://example.com/jquery.plugin_2.js"></script>
<script type="text/javascript">
$(document).ready(function() {
// plugin_1 code...
}
</script>
<script type="text/javascript">
$(document).ready(function() {
// plugin_2 code...
}
</script>
Most Joomla installations also come bundled with MooTools, which uses $ and $$ along with jQuery which uses $. This sounds like the issue you are experiencing. However both frameworks also have their own global variables you can use.
For MooTools it is document.id, for jQuery it is jQuery.
As a general rule closures help out a great deal with compatibility issues with plugins.
You can opt to fix the plugins by using the closures or wrap your $(document).ready() with them. I personally do both.
jQuery https://api.jquery.com/jquery.noconflict/
(function($){
//jQuery code here
}(jQuery));
MooTools http://mootools.net/blog/2009/06/22/the-dollar-safe-mode
(function($){
//MooTools code here
}(document.id));
The same issue can occur with a number of global values/variables, for example the usage of some plugins overriding undefined.
var undefined = null;
var isDefined = (typeof myVar === undefined);
This application of jQuery noConflict worked for me:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="http://example.com/jquery.plugin_1.js"></script>
<script type="text/javascript" src="http://example.com/jquery.plugin_2.js"></script>
<script type="text/javascript">
var $plugin_1 = jQuery.noConflict();
$plugin_1(document).ready(function() {
// replace "$" with "$plugin_1" in all instances of its use here.
// plugin_1 code...
}
</script>
<script type="text/javascript">
var $plugin_2 = jQuery.noConflict();
$plugin_2(document).ready(function() {
// replace "$" with "$plugin_2" in all instances of its use here
// plugin_2 code...
}
</script>
I'm using a jQuery plugin(?)/library called "Zentabs" and for some reason it's preventing any other jQuery code I write from working...this isn't the first time I've had trouble with jQuery library's breaking other pieces of code but usually I can rearange where the code appears and that'll usually fix whatever the problem is but this time nothing's working -_-
This is what I've got in the header;
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
alert("WTF!!!!!");
});
</script>
<script src="<?php baseURL();?>/zentabs.js" type="text/javascript"></script>
<script src="<?php baseURL();?>/date_time.js" type="text/javascript"></script>
<script src="jquery.lazyload.js?v=4" type="text/javascript" charset="utf-8"></script>
When I remove
<script src="<?php baseURL();?>/zentabs.js" type="text/javascript"></script>
Then
$(document).ready(function() {
alert("WTF!!!!!");
});
</script>
Work just fine, but when I include zentabs.js, nothing works =/
And here's the zentabs.js file > http://zenverse.net/wp-content/uploads/2009/09/zentabs.js
Can anybody tell me what I'm doing wrong?
P.S. I'm so freakin' frustrated right now I'm about ready to jump off
a building -_-
You need noConflict there. Try this, then from then forward just use jQuery instead of $()
$.noConflict();
jQuery(document).ready(function() {
alert("WTF!!!!!");
});
You could also set jQuery to a variable if you want, so its a bit shorter to type on all your calls later.
var jq = jQuery;
jq(document).ready(function() {
alert("WTF!!!!!");
jq('input').val( '...' );
});
Read more about noConflict on http://api.jquery.com/jQuery.noConflict/
try this if this solves:
$(document).ready(function() {
$.noConflict();
alert("WTF!!!!!");
});
your can find documentation here: http://api.jquery.com/jQuery.noConflict/
While using jquery or javascript code most of the time i have to face the problem of jquery or javascript conflict.
Still i haven't got the reason why this stuff get conflict with other code?
Any one have any idea about this?
And any solution so that next time this issue will not occur while project development.
I have one solution to stop the conflict of jquery files that is,
<script>
var j$=jQuery.noConflict();
</script>
but all the time this code is not working.
If you are using another JavaScript library that uses the $ variable, you can run into conflicts with jQuery. In order to avoid these conflicts, you need to put jQuery in no-conflict mode immediately after it is loaded onto the page and before you attempt to use jQuery in your page.
Method 1:
When you put jQuery into no-conflict mode, you have the option of assigning a variable name to replace $. ( only once )
<script src="prototype.js"></script>
<script src="jquery.js"></script>
<script>var $j = jQuery.noConflict();</script>
Method 2
You can continue to use the standard $ by wrapping your code in a
self-executing anonymous function; this is a standard pattern for
plugin authoring, where the author cannot know whether another library
will have taken over the $.
<script src="jquery.js"></script>
<script>
jQuery.noConflict();
(function($) {
// your code here, using the $
})(jQuery);
</script>
Method 3:
use jQuery instead of $
there few other ways to do so
reference
For jQuery, it's explained in noConflict's API page; basically, many JS frameworks use $ as a function name, and so they may conflict if more than one is used. Which it shouldn't anyway.
Try placing this in your header:
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.1/jquery-ui.min.js"> </script>
Try to give an alert when DOM is ready and find it alerts or not if not there is a conflict
<script>
$(document).ready(function () {
alert("Hello!");
});
</script>
I there is conflict try this:
<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.noConflict();
jQuery(document).ready(function($) {
// Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>
