1/* DefaultButtons/Validators/FireFox Textarea Fix */
2/*
3  This function is used to override the default ASP.NET FireDefaultButton function to 
4  fix non-IE issues with the script.  
5  
6  This override will fix:
7    - FireFox issue where the form submits when en a textarea and enter is clicked 
8      the default function from MS uses "srcElement" to locate the source control
9      this does not work in non-IE browsers
10    
11  To use: 
12    - include this script on the page after the embedded javascript file generated 
13      by ASP.NET to override the default action.
