如何有条件地包含外部 javascript 文件?

How to include an external javascript file conditionally?(如何有条件地包含外部 javascript 文件?)

问题描述

I have this code:

<script src="http://external/js/file/url.js">
</script>

I want to do something like this-

<script>
if(2>1){
//include http://external/js/file/url.js
}
</script>

Any idea?

This question has been asked before in Include a Javascript File in another Javascript File. This peice of code may fit what you have been looking for

function include(filename)
{
   var head = document.getElementsByTagName('head')[0];

   var script = document.createElement('script');
   script.src = filename;
   script.type = 'text/javascript';

   head.appendChild(script)
}   

if that script does not work, i suggest you to look over and read the post above: Include a Javascript File in another Javascript File.

I hope this helps, it may not be the answer you had been looking for, but it may just help.
