Passing STATIC_URL to file javascript with django

Using a global javascript variable with the static url value is more simple :

<script language="javascript">var STATIC_URL = "{{ STATIC_URL|escapejs }}";</script>
<script src="{{ STATIC_URL }}js/myfile.js"></script>

Then, you can simply use the static url by calling STATIC_URL in myfile.js :

html = '<img src="'+STATIC_URL+'/icons/flags/tn.gif">';
