In my main.js file : I configured the contentScriptFile to be script.js . Also, this script file is embedded in index.html which is a tab which will be opened using tabs.open .
I have self.port.on and jquery related things in that script file . If self.port is written on the top of other jquery things, self.port.on is working and jquery is not working . But, self.port.on is written below, jquery is working fine and self.port is not working.
The script file actually deals with the data obtained using self.port (will come only when tab opened,).
What about wrap all your jQuery code in a safe environment?
Using $:
(function($) {
// use $
})(jQuery)
Using $jq:
(function($jq) {
// use $jq
})(jQuery)
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():
<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.noConflict();
// Code that uses other library's $ can follow here.
</script>
This technique is especially effective in conjunction with the .ready() method's ability to alias the jQuery object, as within callback passed to .ready() we can use $ if we wish without fear of conflicts later:
<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.
$("div").hide();
});
// Code that uses other library's $ can follow here.
$("content").style.display = 'none';
</script>
Source: jQuery.noConflict
Use jQuery's noConflict setting.
$jq = jQuery.noConflict(); //use $jq instead of $

I've found many other similar questions but this particular scenario is somewhat unique to the more typical ones to which the prior questions are applicable.
My understanding and the normal approach I use to resolve conflicts between 2 versions of JQuery are as follows in this example:
<script type="text/javascript" src="../Static/jquery-1.3.2.min.js" ></script>
<script type="text/javascript" src="/Scripts/jquery-ui 1.12.1.custom/jquery.js"></script>
<script type="text/javascript">
var JQuery_1_12_1 = $.noConflict(true);
$JQuery_1_12_1(document).ready(function () {
// Code dependent on JQuery 1.12.1 can safely execute here without
// conflicting with version 1.3.2
});
</script>
<script type="text/javascript">
// Code executed within this block will use 1.3.2
</script>
Alternatively, I could have duplicated the approach implemented to define the noConflict variable for 1.12.1 for 1.3.2 and the result would have been the same.
The problem I'm having difficulty in resolving is that I'm confronted with a situation I previously haven't had to deal with where there are linked library dependencies that need to be combined together in a noConflict manner.
Here is the current situation:
<script type="text/javascript" src="../Static/jquery-1.3.2.min.js" ></script>
<script type="text/javascript" src="/Scripts/jquery-ui-1.12.1.custom/jquery-ui.js"></script>
<script type="text/javascript" src="/Scripts/jquery-ui 1.12.1.custom/jquery.js"></script>
<script type="text/javascript">
var JQuery_1_12_1 = $.noConflict(true);
$JQuery_1_12_1(document).ready(function () {
// Code dependent on JQuery 1.12.1 can safely execute here without
// conflicting with version 1.3.2 but do to the lack of the dependent version this code will always break
});
</script>
<script type="text/javascript">
// Code executed within this block will use 1.3.2
</script>
As you can note, there is an inter-dependency between jquery-ui.js and jquery.js and due to this inter-dependency the $JQuery_1_12_1 variable cannot be applicable to both.
Alternatively, creating a separate noConflict variable for the jquery-ui.js library would require it to be placed within the context of a separate script tag which would essentially break the dependency and the code won't function correctly.
How can this problem be resolved?
I have also tried using the same versions of one of the JQuery libraries to alleviate the conflicts but they each have a unique set of features that don't crossover. So only one version will work per required application within the code.
First: Don't use multiple versions of jQuery. It bloats and complicates your page. Use an up-to-date version of jQuery and, if you have plugins that don't work with that up-to-date version, update them so they do (and ideally send a pull-request back to the plugin's repo if it has one), or use something that's actively maintained instead.
Now, if for some reason you can't do that:
Any half-decent jQuery plugin uses the jQuery variable's value as of when the plugin is loaded, by doing something like this:
(function($) {
// Plugin code
})(jQuery);
If you load a different version of jQuery afterward, the plugin still uses the earlier one because it captured the value of jQuery as of when it loaded.
So load your plugins for a given jQuery version immediately after loading that version of jQuery.
Then: Do the same for your own code.
<script src="../Static/jquery-1.3.2.min.js" ></script>
<script src="../plugin/that/needs/version/132.js"></script>
<script src="../your/code/that/needs/version/132.js"></script>
<script type="text/javascript" src="/Scripts/jquery-ui 1.12.1.custom/jquery.js"></script>
<script type="text/javascript" src="/Scripts/jquery-ui-1.12.1.custom/jquery-ui.js"></script>
<script src="../your/code/that/needs/what/jQueryUI/is/using.js"></script>
...where your script code does the same thing a well-behaved plugin does:
(function($) {
// Use $ here
})(jQuery);
If you have code that (shudders) needs to use both versions of jQuery, capture each version in a variable:
<script src="../Static/jquery-1.3.2.min.js" ></script>
<script src="../plugin/that/needs/version/132.js"></script>
<script>
var jQuery_v132 = jQuery;
</script>
<script src="../your/code/that/needs/version/132.js"></script>
<script type="text/javascript" src="/Scripts/jquery-ui 1.12.1.custom/jquery.js"></script>
<script type="text/javascript" src="/Scripts/jquery-ui-1.12.1.custom/jquery-ui.js"></script>
<script>
var jQuery_whatever = jQuery;
</script>
<script src="../your/code/that/needs/what/jQueryUI/is/using.js"></script>
<script src="../your/code/using/both.js"></script>
...where your code using both uses jQuery_v132 or jQuery_whatever as appropriate.
(I've used "whatever" because I have no idea what version of jQuery your jquery-ui 1.12.1.custom/jquery.js file is, but it's unlikely to be jQuery 1.12.1.)
I have multiple jquery libraries loaded, (cant change that, hosted ecom platform, with limited access to certain things) so I need to noconflict them.
current code:
<script type="text/javascript">
$(document).ready(function() {
$('nav#menu').mmenu({
slidingSubmenus: false
});
});
</script>
would like it to use a diff variable like:
<script type="text/javascript">
var jQuery_1_11_1 = jQuery.noConflict(true);
</script>
so something like:
<script type="text/javascript">
jQuery_1_11_1(document).ready(function() {
jQuery_1_11_1('nav#menu').mmenu({
slidingSubmenus: false
});
});
</script>
but, not having any luck...
thanks in advance for any help!
I don't believe .noConflict() is what you're after here as all it will do is remove jQuery from the global $ namespace.
The problem you're having is that you'd like multiple jQuery versions to co-exist on the same page.
Your general approach of assigning to a variable is correct. Script load order is important. If your 1.11.1 version shouldn't conflict with an older version lets say 1.7.2 you need to ensure you load your version first, assign to a variable and then load the version you want to assign to the global $ last
<script type="text/javascript" src="jquery.1.11.1.js"></script>
<script type="text/javascript">
var $jq111 = jQuery;
// here we have set $jq111 to the current jQuery object which is 1.11.1
// at this point $ and jQuery are also 1.11.1
</script>
//IMPORTANT: now you will load any plugins for 1.11.1 these are and should only be accessable with the 1.11.1 library but if the plugin uses the global $ you may have problems more on that later
<script type="text/javascript" src="menu.js"></script>
<script type="text/javascript" src="jquery.1.7.2.js"></script>
<script>
// at this point $ and jQuery are 1.7.2
// $jq111 should be 1.11.1
// to do something with 1.11.1
$jq111('nav#menu')...
// The menu plugin is loaded in the context of 1.11.1
// To ensure subcalls to the global $ work we need to create a block
(function( $, undefined ) {
// $ in this scope is pointing to $jq111
$('nav#menu').menu(...)
}( $jq111 ));
</script>
What errors are you getting? Have you tried this:
<script type="text/javascript">
jQuery_1_11_1(function($) {
$('nav#menu').mmenu({
slidingSubmenus: false
});
});
</script>
I have the following references to the javascripts libraries.
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="modernizr-1.5.min.js"></script>
<script type="text/javascript" src="JavaScript-1.js"></script>
<script>jQuery.noConflict();</script>
<script>
$(document).ready(function () {
$('#tabs-2').html("<p>jQuery add </p>");
});
</script>
In the html there is a div with id tabs-2. I am not able to control the html elements using JQuery scripts. The above simple in-line script is also not working.
I have also added a custom script file which has the jQuery function as stated in this example.
Any inputs on how to add use custom JQuery libraries?
After you call
jQuery.noConflict();
you can no longer use $. You have to use jQuery, or, assign the return value from the noConflict() call to a variable and use that:
var $j = jQuery.noConflict();
$j(document).ready(function($) {
// here you can use $ again
});
To keep your custom scripts compatible whether jQuery is in no-conflict mode or not, you could wrap it with an IIFE:
(function($) {
// your code that uses '$'
})(jQuery);
See: jQuery.noConflict() documentation
The following line
<script>jQuery.noConflict();</script>
means that jQUery runs in no conflict mode. This means that $ is not aliased to the jQuery object and you have to use jQueryisntead of $
You can use the noConflict() function
<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>
JQuery.noConflict()
I can't get the noConflict() method to work properly. I've been searching online for hours and can't seem to get a solid answer. Here's what I have in my header...
<script type="text/javascript" src="js/mootools.js"></script>
<script type="text/javascript" src="js/slimbox.js"></script>
<script type="text/javascript" src="js/jquery.js"></script><!-- jQuery script -->
<script type="text/javascript" src="js/page_scroll.js"></script><!-- JavaScript -->
<script src="js/jquery.easing.1.3.js" type="text/javascript"></script><!-- jQuery easing plug-in -->
<script type="text/javascript">
var $j = jQuery.noConflict();
// Use jQuery via $j(...)
$j(document).ready(function(){
$j("div").hide();
});
// Use Mootools with $(...), etc.
$('someid').hide();
</script>
There's no other jQuery or JavaScript within my HTML (just what I have externally), so "placing anything that uses the $ variable in the noConlict method" is not an option.
Essentially what I'm trying to do is have slimbox and easing page scroll (for my navigation) to work together. The problem is of course one works when the other is removed and vice versa. Also, when I use the noConflict() method I get slimbox to work and not pagescroll, but when I remove the noConflict() method I get pagescroll to work and not slimbox. So apperently noConflict is doing something, I just don't know what that is or how to go about it.
If anyone can help me out, I'd appreciate it. Thanks.
when using other js libs that leverage the $ alias,
I have found reliable results by using
$.noConflict();
jQuery(document).ready(function($) {
// your jQuery code here i.e.
// jQuery('some-selector-expression').somefunction();
});
// prototype or mootools code that uses the $ alias works fine here
So are you saying it does not work when you declare $j? You can define your own alternate names (e.g. jq, $J, awesomeQuery - anything you want). Try calling it something w/o the $
Wrap it in an anonymous function:
(function($){
$(document).ready(function() {
// function here...
});
})(jQuery);
Seeing the exact code might help.
I am using both javascript and jquery code on the same html page. For some reason, the jQuery library is stopping my native javascript code from working properly.
I found this page: jQuery No Conflict that says you can use a jquery.noConflict to release $ back to javascript. However, I'm not sure how to do this?
Specifically, I'm not sure how to implement this correctly? Where does the the Jquery code go, where does the JS code go?
My code is below:
<script type="text/javascript">
$.noConflict();
// Code that uses other library's $ can follow here.
</script>
jQuery.noConflict will reset the $ variable so it's no longer an alias of jQuery. Aside from just calling it once, there's not much else you really need to do. Though, you can create your own alias with the return value, if you'd like:
var jq = jQuery.noConflict();
And, generally, you want to do this right after including jQuery and any plugins:
<script type="text/javascript" src="/path/to/jquery.js"></script>
<script type="text/javascript" src="/path/to/jquery-plugin.js"></script>
<script type="text/javascript">
jQuery.noConflict();
// Code that uses other library's $ can follow here.
</script>
<script type="text/javascript" src="/path/to/prototype.js"></script>
You can also go one step further and free up jQuery with noConflict(true). Though, if you take this route, you'll definitely want an alias as neither $ nor jQuery will probably be what you want:
var jq = jQuery.noConflict(true);
I think this last option is mostly used for mixing versions of jQuery, particularly for out-dated plugins when you want to update jQuery itself:
<script type="text/javascript" src="jquery-1.4.4.js"></script>
<script type="text/javascript" src="jquery-older-plugin.js"></script>
<script type="text/javascript">
var jq144 = jQuery.noConflict(true);
</script>
<script type="text/javascript" src="jquery-1.6.4.js"></script>
<script type="text/javascript" src="jquery-newer-plugin.js"></script>
By default, jquery uses the variable jQuery and the $ is used for your convenience. If you want to avoid conflicts, a good way is to encapsulate jQuery like so:
(function($){
$(function(){
alert('$ is safe!');
});
})(jQuery)
If I'm not mistaken:
var jq = $.noConflict();
then you can call jquery function with jq.(whatever).
jq('#selector');
It's typically used if you are using another library that uses $.
In order to still use the $ symbol for jQuery, I typically use:
jQuery.noConflict()(function($){
// jQuery code here
});
It allows for you to give the jQuery variable a different name, and still use it:
<script type="text/javascript">
$jq = $.noConflict();
// Code that uses other library's $ can follow here.
//use $jq for all calls to jQuery:
$jq.ajax(...)
$jq('selector')
</script>
If you look at the examples on the api page there is this:
Example: Creates a different alias instead of jQuery to use in the rest of the script.
var j = jQuery.noConflict();
// Do something with jQuery
j("div p").hide();
// Do something with another library's $()
$("content").style.display = 'none';
Put the var j = jQuery.noConflict() after you bring in jquery and then bring in the conflicting scripts. You can then use the j in place of $ for all your jquery needs and use the $ for the other script.
In addition to that, passing true to $.noConflict(true); will also restore previous (if any) global variable jQuery, so that plugins can be initialized with correct jQuery version when multiple versions are being used.
You simply assign a custom variable for JQuery to use instead of its default $. JQuery then wraps itself in a new function scope so $ no longer has a namespace conflict.
<script type="text/javascript">
$jQuery = $.noConflict();
// Other library code here which uses '$'
$jQuery(function(){ /* dom ready */ }
</script>
The noConflict() method releases the $ shortcut identifier, so that other scripts can use it for next time.
Default jquery $ as:
// Actin with $
$(function(){
$(".add").hide();
$(".add2").show();
});
Or as custom:
var j = jQuery.noConflict();
// Action with j
j(function(){
j(".edit").hide();
j(".add2").show();
});
<script src="JavascriptLibrary/jquery-1.4.2.js"></script>
<script>
var $i = jQuery.noConflict();
// alert($i.fn.jquery);
</script>
<script src="JavascriptLibrary/jquery-1.8.3.js"></script>
<script>
var $j = jQuery.noConflict();
//alert($j.fn.jquery);
</script>
<script src="JavascriptLibrary/jquery.colorbox.js"></script>
<script src="Js/jquery-1.12.3.js"></script>
<script>
var $NJS = jQuery.noConflict();
</script>
You can do it like this:
<script>
$i.alert('hi i am jquery-1.4.2.js alert function');
$j.alert('hi i am jquery-1.8.3.js alert function');
</script>
Today i have this issue because i have implemented "bootstrap menu" that uses a jQuery version along with "fancybox image gallery". Of course one plugin works and the other not due to jQuery conflict but i have overcome it as follow:
First i have added the "bootstrap menu" Js in the script footer as the menu is presented allover the website pages:
<!-- Top Menu Javascript -->
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript">
var jq171 = jQuery.noConflict(true);
</script>
And in the "fancybox" image gallery page as follow:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="fancybox/js/libs/jquery-1.7.1.min.js"><\/script>')</script>
And the good thing is both working like a charm :)
Give it a try :)
I fixed that error by adding this conflict code
<script type="text/javascript">
jQuery.noConflict();
</script>
after my jQuery and js files and get the file was the error (found by the console of browser) and replace all the '$' by jQuery following this on all error js files in my Magento website. It's working for me good.
