Converting C# regex to JavaScript regex

Question

In C# I am using this regex:

 string pattern = @"(?<!"")\:([^\:]*)\:";

and it is working fine but when I try to use it in JavaScript it gives Syntax error:

var pattern = /(?<!"")\:([^\:]*)\:/g;

Can you let me know the issue with that regex with JavaScript?

@raj: what do you want to do with this regex? Matching? replacing?... — willeM_ Van Onsem

Can you explain what you want the expression to find and give an example of sample inputs/matches? — Colin

JavaScript do not support Zero-width negative lookbehind assertion.
