jQuery noConflict method
jQuery uses the $ sign as a shortcut for jQuery.
There are many other popular JavaScript frameworks like: Angular, Backbone, Ember, Knockout, and more. Many of these libraries also use $ as a function or variable name. If two different frameworks are using the same shortcut, one of them might stop working.
How jQuery noConflict works?
In jQuery’s case, $ is just an alias for jQuery, so all functionality is available without using $. If you need to use another JavaScript library alongside jQuery, return control of $ back to the other library with a call to $.noConflict().
The noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it.
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
// Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>You can also create your own shortcut very easily. The noConflict() method returns a reference to jQuery, that you can save in a variable, for later use. Here is an example:
<script>
var jq = $.noConflict();
jq(document).ready(function(){
jq("button").click(function(){
jq("p").text("jQuery is still working!");
});
});
</script>jQuery Conflict Fix:
Steps to take if your jQuery is not working:
- The jQuery library file is not there or does not exist.
- Incorrect File Path while including jQuery
- Don’t load two different javascript library versions, only one is ever needed.
- Script load order & Including jQuery Before Other Libraries
- Javascript library issues & Putting jQuery Into No-Conflict Mode
- Javascript disabled/not supported by browser
