there are many ways to do it.
the most common is probably loading the script as text ajax style
the using eval() to turning the text into javascript.
I personally don't like using eval.
what I prefer to do is to use the dom to add a script tag. You have to
use dom methods innerhtml doesn't work for this.
here is an example of the script to do this.
javascript:(function(){var
head=document.getElementsByTagName('head').item(0);var
scriptTag=document.getElementById('loadScript');if(scriptTag)head.removeChild(scriptTag);script=document.createElement('script');script.src='http://localhost:6673/bm/bm.js';script.type='text/javascript';script.id='loadScript';head.appendChild(script)})();
another method i like especially if i want to load someone else's
script is using innerhtml to load an iframe it has to be 1x1 pixel
if you use display none it will fail in webkit browers (safari)
here are some writes ups on the various methods.
in the end it depends on what you want to do.
