Question

Basically, I want to do this:

<script src=" path + '/jquery.js'"></script>

(Obviously that won’t work.)

I have a standalone page loading external scripts with <script>, but the URL needs to be prefixed with the variable path (because the page is run on different servers in different environments). I easily get path from the URL which always ends with “?path=X” where X is the actual path.

If I had jQuery, I know I could use getScript() to dynamically load external .js files, but jQuery is one of the files I need to load! I don’t need anything too complicated here, no need to worry about encoding or file-types, it’s a fairly simple situation except for the changing servers.

You need to use plain javascript if jquery not loaded. Something like that:

        var fileref=document.createElement('script');
          fileref.setAttribute("type","text/javascript");
          fileref.setAttribute("src", path + '/jquery.js');
          document.getElementsByTagName("head")[0].appendChild(fileref);
          fileref.onload = function(){alert('loaded')};
