How to get everything in between these two strings?

Question

How can I get everything between these two strings?

ATemp.runFunct( <I WANT EVERYTHING IN BETWEEN THESE TWO PARENS> ), // comment

I want everything in between the parens above, with the outside strings as a constant.

I have tried multiple regex expressions, but they have not worked, such as:

ATemp\\.runFunct\\(*.?\\), \\/\\/ comment

Any ideas? Thanks! (PS, I'm using javascript)

Answer 1

Here is the FIDDLE: http://jsfiddle.net/mikea80/kSuk4/

var str = "(Hello world!)";
var startIndex = str.indexOf("(");
var endIndex = str.indexOf(")");
var res = str.substring(startIndex + 1, endIndex); 
alert(res);

*.? should be .*? . Otherwise you are matching zero or more ( . You probably also want to use a capture group so that you can actually reference that part later on: (.*?)

Example:

var match = /ATemp\.runFunct\((.*?)\), \/\/ comment/.exec('ATemp.runFunct( <I WANT EVERYTHING IN BETWEEN THESE TWO PARENS> ), // comment');
alert(match[1]);

.exec returns an array, where the first element is the complete match and the second element is the value of the first capture group (and so on).
