So i want to run a custom script in WP, I have got jquery 

```
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js?ver=1.11.3'`></script>

```

in my footer when i view source, but i cant as it throws me an error 

`Uncaught TypeError: $ is not a function`

```
$( document ).ready(function() {
    console.log( "ready!" );
});

```

This is the code, well you would guess it should run... but its not.

any advice?
