Is it possible to overwrite internal javascript? I am working for a non profit as an internship and they want to escape a template that almost all of the non profits in that organization have to use, the catch is the template is written in Javascript if it is possible to over ride it please tell me as I really need to know ASAP.
I may not always be correct.

my be this would(i have not tired it). Javascript code are written in <script></script> tags. So search these tags in the document by using: var sTag = document.getElementsByTagName("script"). This will give u an array of script tags. Now over write them by using sTag[0].innerHTML = "your javascript code";
If this work please let me know?

Okay I have searched the whole javascript and they do not use the var command at all they use javascript in a odd way just for images. If there is a way to overwrite it I would be happy and so would my boss.

Hi tiger86, if u can explain ur problem little bit more, i want to know what exactly u want to do.
var is not a command but a way to declare a variable in javascript.
I am explaining my prev. post again, if u still did not get ur problem solved, explain ur problem in detail.
first i want to tell u what i understand from ur post: You want to overwrite the javacript at run-time. if this is correct then my post will help u otherwise explain me ur problem. here is want i explained in prev post. for example u have a page:
if u want to change js code in above page,
this a js code todo that :
var tags = document.getElementsByTagName("script");
//Now changing the js code
tags[0].innerHTML = "your new js code should be written here as a string";
again i had not tested it. please let me know how it works?
