Question

I am very new to web development and Javascript in general and I hae done some Jquery coding by adding my code in my HTMl code all the time. Now, I just moved the same code to my .Js file and my console shows me following error:

$ is not defined [Break On This Error] $(document).ready(function () {

It just says JQuery is not defined. It means that I can not refer to Jquery or any other Javascript files in my Js file?

Or there is something that I am missing here?

Answer 1

Just include jQuery before your script is called

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

For other jQuery stuff available in CDN, see this:
http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery

Update: This is as close to “using” as you can get, in my mind. It’s not required to download the jQuery library to your system or host it on your server.
