Jquery conflict in Magento - javascript

Hi I am learning Javascript and am stuck resolving a JS related issue on my project http://www.merekhayaal.com/ I have installed Masonry layout which is conflicting with the rest of JS. I have read this usually has to do with fixing jQuery. I am only asking for pointers here. I need the following code to make the Masonry layout work:
<script src="babezlondon/modernizr-latest.js">
</script>
<script src="//code.jquery.com/jquery-1.8.3.min.js"></script>
<script>window.jQuery || document.write('<script src="js/shopshark/jquery-1.8.3.min.js"><\/script>')</script>
<script src="babezlondon/jquery.masonry.min.js"></script>
<script src="babezlondon/script.js"></script>
But when I put this in, the rest of JS on the page breaks. If the solution is to implement no-conflict in jQuery, what steps can I take to ensure I do it correctly in my case as there are multiple js files to deal with?

Have you already tried using jQuery noConflict? http://api.jquery.com/jquery.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>

Just use jQuery in noConflict() mode.
Stick this at the bottom of the jQuery script;
var $jq=jQuery.noConflict();
so now you would have to use $jq instead of $jQuery or $
This way, each script you have for different sliders etc you can change the var $jq to suit.
Hope this helps.

Ok so what worked is when i removed a line of code
<script src="//code.jquery.com/jquery-1.8.3.min.js"></script>
from the script. It was apparently causing the conflict

jQuery giving errors "$ is not defined" [duplicate]

I have a simple jquery click event
<script type="text/javascript">
$(function() {
$('#post').click(function() {
alert("test");
});
});
</script>
and a jquery reference defined in the site.master
<script src="<%=ResolveUrl("~/Scripts/jquery-1.3.2.js")%>" type="text/javascript"></script>
I have checked that the script is being resolved correctly, I'm able to see the markup and view the script directly in firebug, so I must be being found. However, I am still getting:
$ is not defined
and none of the jquery works. I've also tried the various variations of this like $(document).ready and jQuery etc.
It's an MVC 2 app on .net 3.5, I'm sure I'm being really dense, everywhere on google says to check the file is referenced correctly, which I have checked and checked again, please advise! :/
That error can only be caused by one of three things:
Your JavaScript file is not being properly loaded into your page
You have a botched version of jQuery. This could happen because someone edited the core file, or a plugin may have overwritten the $ variable.
You have JavaScript running before the page is fully loaded, and as such, before jQuery is fully loaded.
First of all, ensure, what script is call properly, it should looks like
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
and shouldn't have attributes async or defer.
Then you should check the Firebug net panel to see if the file is actually being loaded properly. If not, it will be highlighted red and will say "404" beside it. If the file is loading properly, that means that the issue is number 2.
Make sure all jQuery javascript code is being run inside a code block such as:
$(document).ready(function () {
//your code here
});
This will ensure that your code is being loaded after jQuery has been initialized.
One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described.
Note: If you're loading code which does not require jQuery to run it does not need to be placed inside the jQuery ready handler. That code may be separated using document.readyState.
It could be that you have your script tag called before the jquery script is called.
<script type="text/javascript" src="js/script.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
This results as $ is not defined
Put the jquery.js before your script tag and it will work ;) like so:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript" src="js/script.js"></script>
First you need to make sure that jQuery script is loaded. This could be from a CDN or local on your website. If you don't load this first before trying to use jQuery it will tell you that jQuery is not defined.
<script src="jquery.min.js"></script>
This could be in the HEAD or in the footer of the page, just make sure you load it before you try to call any other jQuery stuff.
Then you need to use one of the two solutions below
(function($){
// your standard jquery code goes here with $ prefix
// best used inside a page with inline code,
// or outside the document ready, enter code here
})(jQuery);
or
jQuery(document).ready(function($){
// standard on load code goes here with $ prefix
// note: the $ is setup inside the anonymous function of the ready command
});
please be aware that many times $(document).ready(function(){//code here}); will not work.
If the jQuery plugin call is next to the </body>, and your script is loaded before that, you should make your code run after window.onload event, like this:
window.onload = function() {
//YOUR JQUERY CODE
}
`
so, your code will run only after the window load, when all assets have been loaded. In that point, the jQuery ($) will be defined.
If you use that:
$(document).ready(function () {
//YOUR JQUERY CODE
});
`
the $ isn't yet defined at this time, because it is called before the jQuery is loaded, and your script will fail on that first line on console.
I just did the same thing and found i had a whole lot of
type="text/javacsript"
So they were loading, but no further hint as to why it wasn't working. Needless to say, proper spelling fixed it.
Use a scripts section in the view and master layout.
Put all your scripts defined in your view inside a Scripts section of the view. This way you can have the master layout load this after all other scripts have been loaded. This is the default setup when starting a new MVC5 web project. Not sure about earlier versions.
Views/Foo/MyView.cshtml:
// The rest of your view code above here.
#section Scripts
{
// Either render the bundle defined with same name in BundleConfig.cs...
#Scripts.Render("~/bundles/myCustomBundle")
// ...or hard code the HTML.
<script src="URL-TO-CUSTOM-JS-FILE"></script>
<script type="text/javascript">
$(document).ready(function () {
// Do your custom javascript for this view here. Will be run after
// loading all the other scripts.
});
</script>
}
Views/Shared/_Layout.cshtml
<html>
<body>
<!-- ... Rest of your layout file here ... -->
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/bundles/bootstrap")
#RenderSection("scripts", required: false)
</body>
</html>
Note how the scripts section is rendered last in the master layout file.
It means that your jQuery library has not been loaded yet.
You can move your code after pulling jQuery library.
or you can use something like this
window.onload = function(){
// Your code here
// $(".some-class").html("some html");
};
As stated above, it happens due to the conflict of $ variable.
I resolved this issue by reserving a secondary variable for jQuery with no conflict.
var $j = jQuery.noConflict();
and then use it anywhere
$j( "div" ).hide();
more details can be found here
make sure you really load jquery
this is not jquery - it's the ui!
<script language="JavaScript"
src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js">
</script>
This is a correct script source for jquery:
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
Are you using any other JavaScript libraries? If so, you will probably need to use jQuery in compatibility mode:
http://docs.jquery.com/Using_jQuery_with_Other_Libraries
after some tests i found a fast solution ,
you can add in top of your index page:
<script>
$=jQuery;
</script>
it work very fine :)
I had the same problem and resolved it by using
document.addEventListener('DOMContentLoaded', () => {
// code here
});
I got the same error message when I misspelled the jQuery reference and instead of type="text/javascript" I typed "...javascirpt". ;)
It sounds like jQuery isn't loading properly. Which source/version are you using?
Alternatively, it could a be namespace collision, so try using jQuery explicitly instead of using $. If that works, you may like to use noConflict to ensure the other code that's using $ doesn't break.
That error means that jQuery has not yet loaded on the page. Using $(document).ready(...) or any variant thereof will do no good, as $ is the jQuery function.
Using window.onload should work here. Note that only one function can be assigned to window.onload. To avoid losing the original onload logic, you can decorate the original function like so:
originalOnload = window.onload;
window.onload = function() {
if (originalOnload) {
originalOnload();
}
// YOUR JQUERY
};
This will execute the function that was originally assigned to window.onload, and then will execute // YOUR JQUERY.
See https://en.wikipedia.org/wiki/Decorator_pattern for more detail about the decorator pattern.
I use Url.Content and never have a problem.
<script src="<%= Url.Content ("~/Scripts/jquery-1.4.1.min.js") %>" type="text/javascript"></script>
In the solution it is mentioned -
"One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described."
For avoiding this -
Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If we need to use another JavaScript library alongside jQuery, we can return control of $ back to the other library with a call to $.noConflict():
I had this problem once for no apparent reason. It was happenning locally whilst I was running through the aspnet development server. It had been working and I reverted everything to a state where it had previously been working and still it didn't work. I looked in the chrome debugger and the jquery-1.7.1.min.js had loaded without any problems. It was all very confusing. I still don't know what the problem was but closing the browser, closing the development server and then trying again sorted it out.
Just place jquery url on the top of your jquery code
like this--
<script src="<%=ResolveUrl("~/Scripts/jquery-1.3.2.js")%>" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$('#post').click(function() {
alert("test");
});
});
</script>
I had the same problem and it was because my reference to the jQuery.js was not in the tag. Once I switched that, everything started working.

Check the exact path of your jquery file is included.
<script src="assets/plugins/jquery/jquery.min.js"></script>
if you add this on bottom of your page , please all call JS function below this declaration.
Check using this code test ,
<script type="text/javascript">
/***
* Created by dadenew
* Submit email subscription using ajax
* Send email address
* Send controller
* Recive response
*/
$(document).ready(function() { //you can replace $ with Jquery
alert( 'jquery working~!' );
});
Peace!
This is the common issue to resolve this you have to check some point
Include Main Jquery Library
Check Cross-Browser Issue
Add Library on TOP of the jquery code
Check CDNs might be blocked.
Full details are given in this blog click here
I came across same issue, and it resolved by below steps.
The sequence of the scripts should be as per mentioned below
<script src="~/Scripts/jquery-3.3.1.min.js"></script>
<script src="~/Scripts/jquery-ui.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
This sequence was not correct for my code, I corrected this as per the above and it resolved my issue of Jquery not defined.
We have the same problem....but accidentally i checked folder properties and set something...
You have to check the properties of each folders that you're accessing..
right click folder
'permissions' tab
set the folder access :
OWNER: create and delete files
GROUP: access files
OTHERS: access files
I hope that this is the solution......
When using jQuery in asp.net, if you are using a master page and you are loading the jquery source file there, make sure you have the header contentplaceholder after all the jquery script references.
I had a problem where any pages that used that master page would return '$ is not defined' simply because the incorrect order was making the client side code run before the jquery object was created. So make sure you have:
<head runat="server">
<script type="text/javascript" src="Scripts/jquery-VERSION#.js"></script>
<asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
</head>
That way the code will run in order and you will be able to run jQuery code on the child pages.
In my case I was pointing to Google hosted JQuery. It was included properly, but I was on an HTTPS page and calling it via HTTP. Once I fixed the problem (or allowed insecure content), it fired right up.
After tried everything here with no result, I solved the problem simply by moving the script src tag from body to head
I was having this same problem and couldn't figure out what was causing it. I recently converted my HTML files from Japanese to UTF-8, but I didn't do anything with the script files. Somehow jquery-1.10.2.min.js became corrupted in this process (I still have no idea how). Replacing jquery-1.10.2.min.js with the original fixed it.
it appears that if you locate your jquery.js files under the same folder or in some subfolders where your html file is, the Firebug problem is solved. eg if your html is under C:/folder1/, then your js files should be somewhere under C:/folder1/ (or C:/folder1/folder2 etc) as well and addressed accordingly in the html doc. hope this helps.
I have the same issue and no case resolve me the problem. The only thing that works for me, it's put on the of the Site.master file, the next:
<script src="<%= ResolveUrl("~/Scripts/jquery-1.7.1.min.js") %>" type="text/javascript"></script>
<script src="<%= ResolveUrl("~/Scripts/bootstrap/js/bootstrap.min.js") %>" type="text/javascript"></script>
With src="<%= ResolveUrl("")... the load of jQuery in the Content Pages is correct.

Conflicting Scripts (javascript and jquery)

<script type="text/javascript" src="js/prototype.lite.js"></script>
<script type="text/javascript" src="js/jquery.csvToTable.js"></script>
<script>
$(function() {
$('#CSVTable_Pach').CSVToTable...
});
The script on top is part of a lightbox feature, however it is not allowing a table to display.
How can i resolve the conflict between these scripts?

You may be having a conflict because both libraries use the $ shortcut. Look into the noconflict feature of jQuery or the equivalent of prototype.
You can read more here: jQuery ... Avoiding Conflicts with Other Libraries

Yet another jQuery noConflict()

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><!-- jQuery and $ now point to 1.10.2 -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script><!-- jQuery and $ now point to 1.11.0 -->
<script>
$11 = $.noConflict();
// $11 now points to 1.11.0
// $ still points to 1.10.2
</script>
<!-- SB Admin Scripts -->
<script src="js/sb-admin.js"></script>
<!-- carouFredSel -->
<script src="js/jquery.carouFredSel-6.2.1.js" type="text/javascript"></script>
<script src="js/carouFredSel-hookup.js" type="text/javascript"></script>
I have problems getting this right.
The script sb-admin.js doesn't work together with the carouFredSel.js on the same page. The code above shows my attempt to use 2 different jQuery libraries and 2 different variables($ and $11), each of them pointing to one of the libraries.
In the script sb-admin.js I only use the variable $11 and in jquery.carouFredSel.js and carouFredSel-hookup.js only the variable ยง.
At the moment none of the functions seem to work. What am I doing wrong here?
Any help appreciated.
According to the documentation
If for 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.
You didn't provide the true argument. Change it to:
<script>
$11 = $.noConflict(true);
// $11 now points to 1.11.0
// $ still points to 1.10.2
</script>
I have no idea whether this will solve the overall problem of conflicts between the two other libraries. It seems unlikely that it's because they require different versions of jQuery.
I did try you recommendation and set the noConflict to (true),
but it did not help whatsoever.
In the meantime I found a workaround but unfortunately I can't tell why it works now.
I am using another function for about the same menu and this one apparently doesn't conflict with my carousel.
This is the script that conflicted with the carouFredSel script was the menu from here:
http://startbootstrap.com/templates/sb-admin-v2/
And this is the other menu script that works fine with carouFredSel is this:
http://demo.onokumus.com/metisMenu/

Why do I need jquery.min.js vs just jquery.js for script to work?

I'm new to Wordpress and this has been bugging me for a while. I'm wondering why the code I'm trying to include only works when I include jquery.min.js in 'head' despite the child theme already including jquery.js by default. Let me explain below.
I have a script near the end of my 'body' to specify images in galleries to not have a 'pin it' button show up when hovering over them:
<script type="text/javascript">
$(document).ready(function() {
$(".tiled-gallery-item a img").attr("nopin","nopin");
});
</script>
This code only works (ie., the nopin attribute is added to the relevant img tags) when I include this in the 'head':
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript" /></script>
However, it appears from inspecting source that the child theme already includes jquery.js:
<script type="text/javascript" src="http://blog.froy.com/wp-includes/js/jquery/jquery.js?ver=1.10.2"></script>
<script type="text/javascript" src="http://blog.froy.com/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.2.1"></script>
Why the heck is the jquery.min.js necessary? I'm new to Wordpress and it's so confusing. I thought the jquery.min.js and jquery.js has no functional difference. What is the jquery-migrate.min.js?
WordPress comes with built-in jQuery but doesn't load it by default. it's probably because your theme has been applied wp_enqueue_script('jquery'); inside functions.php
One solution for you to replace this default behavior is to add this snippet to your functions.php:
function modify_jquery() {
if (!is_admin()) {
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js', false, '1.8.1');
wp_enqueue_script('jquery');
}
}
add_action('init', 'modify_jquery');
Also, because you're using use jQuery version 1.10.2, jQuery migrate used here to detect and restore APIs or features that have been deprecated and removed as of version 1.9.
Felix provided exactly what was needed. To fully answer my question for future visitors, let me explain in specifics.
Basically, Wordpress includes the jQuery library by default regardless of your theme (I personally use the Genesis framework with a child theme). In addition, Wordpress, by default, sets the library to noConflict() mode. This is to prevent compatibility problems with other JavaScript libraries that WordPress can link.
If you want to include any scripts that require jquery, you need to use the wp_enqueue_script().
Now this was the important part. If you don't want to go through the troubles and want to include a simple, quick, script at the end of your <body> or elsewhere without having to go into functions.php and using enqueue, replace the $() shortcut with jQuery().
In my case,
<script type="text/javascript">
$(document).ready(function() {
$(".tiled-gallery-item a img").attr("nopin","nopin");
});
</script>
needed to be...
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery(".tiled-gallery-item a img").attr("nopin","nopin");
});
</script>
That's it! I was able to remove the redundant jquery.min.js and simply rely on Wordpress' default jQuery library.
I figured this out by reading this and this. You can find more details in those links.

jQuery noConflict for a dummy

I have a jQuery plugin conflict in Wordpress which I need some help with. On my test page at: http://timbaggaley.co.uk/test/ I have installed the Easy Fancybox plugin for image and video presentation. It worked fine until I installed the jQuery backstretch plugin using code posted into a Javascript adder widget. I'm guessing my problem is the call on multiple libraries and I need to use noConflict. I have amended my code to:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://www.timbaggaley.co.uk/js-includes/jq_backstretch/jquery.backstretch.js"></script>
<script type="text/javascript">
var $j = $.noConflict();
$j(document).ready(function() {
$j.backstretch("http://timbaggaley.co.uk/backstretch/pic4.jpg", {speed: 150});});
</script>
The backstretch still works but the Fancybox still does not. I am a complete programming novice and I have read as much of the jQery noConflict advice as I can find but cannot figure it out. Can anyone help me with some copy 'n' paste idiot-proof guidance on how to implement the noconflict trick into my website?
Thanks
Tim, London
Well, actually, Easy Fancybox uses jQuery, so this is not an issue of using multiple libraries. Therefore you should not use .noConflict().
First remove "var $j = $.noConflict();" and Try using "jQuery" instead of "$j"
I would normally just called $.noConflict() rather than store it in a variable.
Also, you can avoid conflict all together (normally) by using jQuery(document).ready() instead of $.
