Regular Expression to get parameter list from function definition [duplicate]

Answer 1

Let me suggest you using regular expressions:

• [match] /function[^(]*\(([^)]*)\)/ will match the argument list
• [split] /\W+/ (against the results of the first match data) will split the match into params list

So, the code should look like this:

var s = "function moo (paramOne, paramTwo) { alert('hello'); }";
var s2 = s.match(/function[^(]*\(([^)]*)\)/)[1];
var paramList = s2.split(/\W+/);
