3 Ways To Solve Jquery - Uncaught Referenceerror: $ Is Non Defined Error
If you lot are using jQuery, Angualr JS or apparently former JavaScript as well as getting "Uncaught ReferenceError: $ is non defined" error which agency $ is either a variable or a method which you lot are trying to utilisation earlier declaring it using var keyword. In jQuery, it's a curt scream of jQuery() business office as well as most usually used inward $(document).ready(function()). If you lot are doing or hence jQuery materials when DOM is loaded as well as getting this error it agency your browser has a occupation loading jQuery library either from the mesh or local file system. In this article, you lot volition run across or hence of the most mutual reasons of "Uncaught ReferenceError: $ is non defined" error as well as how to solve them, but earlier that let's larn or hence basic well-nigh the dreaded Uncaught ReferenceError: $ is non defined error.
One of the mutual argue of such error is direct starting alongside jQuery without knowing JavaScript fundamentals. I receive got seen many spider web developers which comes from Java, C#, HTML, as well as Python background, started using jQuery without knowing much well-nigh JavaScript.
If you lot hap to piece of work on same scenario, I strongly propose you lot to read atleast i of the skillful JavaScript mass for beginners e.g. Head First JavaScript. Always retrieve that jQuery is a library built on JavaScript, i time you lot know JavaScript, it's much easier to troubleshoot whatever jQuery error.
Similarly, if you lot access a method earlier declaring it you lot volition acquire this error every bit shown below:
Now that you lot receive got learned when does browser throws Uncaught ReferenceError: $ is non defined, it's fourth dimension to await at or hence mutual reasons this error occurs spell using jQuery, AngularJS or other JavaScript library which uses $ every bit a shortcut.
1) One of the most mutual argue of "ReferenceError: $ is non defined" inward jQuery based application is that jQuery plugin is included earlier jQuery file. Since jQuery plugin uses $, it throw "ReferenceError: $ is non defined" if it doesn't find, which is logical because jQuery was non loaded until then.
Solution: Include the jquery.js file earlier whatever jQuery plugin files.
2) The instant most mutual argue of getting "ReferenceError: $ is non defined" inward jQuery is due to the wrong path, either it's a typo or jQuery file is moved to another location, the browser is non able to charge the jQuery file.
One solution of this occupation is exactly to prepare the path to jQuery library. If you lot are downloading jQuery from CDN as well as hence you lot tin besides utilisation Google hosted jQuery file, which is almost ever available.
3) Another bizarre but a mutual argue of "ReferenceError: $ is non defined" inward jQuery" is that you lot mightiness live on working offline but loading jQuery from internet. It's i of the giddy error every spider web
developer makes it sometime or other. Solution is simple, either connect to mesh or utilisation a local re-create of jQuery library every bit shown below:
That's all well-nigh how to prepare the "Uncaught ReferenceError: $ is non defined" inward jQuery. You tin follow similar approach to whatever other JavaScript library which is using $ every bit shortcut. Most of the cases mentioned hither besides applicable to mutual libraries similar AngularJS as well as others every bit well.

Uncaught ReferenceError: X is non defined
Since JavaScript executes within browser, your browser similar FireFox, Chrome, Edge or Internet Explorer throws this error when you lot are using a variable which is non defined, for example, next code volition ce this error, but i time you lot declare the variable using var keyword, the error volition acquire away:data; // ReferenceError: information is non defined var data; data; // No to a greater extent than errors
Similarly, if you lot access a method earlier declaring it you lot volition acquire this error every bit shown below:
process(); // ReferenceError : procedure is non defined process = function(){}; process(); // No errors
