jQuery CDN is not loading on LocalHost

javascript jquery cdn

Solution 1

You aren't actually running on localhost (http://localhost) but on the local file system (file:///path/to/whatever.html). The protocol is copied with the // link to file://ajax.googleapis.com which of course doesn't exist.

You should set up a server on your computer so that you'd have an actual localhost accessed with the http protocol. It would have other benefits as well since browsers act a bit differently also in other regards when the page is loaded directly from the file system.

Solution 2

Have you tried removing the "//" at the beginning of the "src" attribute and instead using "http://"? It is probably appending "localhost" to the beginning of the URL because of those slashes.

I have a jquery cdn loading from the following:
```
<head>
.
.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
```
then in the body I have my source for my script
```
<body>
.
.<script src="app.js"></script>
</body>
```
This is all on local, but when I view in browser I keep getting the following errors in console:
```
GET file://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js
Uncaught ReferenceError: $ is not defined 
```
I assume this is saying the jQuery function "$..." is undefined because there is an error in GET of the CDN, why would this be happening on local?
