Question

Trying to get “Table 2” or whatever table number it might be (sometimes 2 digits) into a variable. Any idea why this is returning null?

 var productText = '25-08-12 Boat Cruise (Table 2)';
 var rgx = /^\(\)$/;
 var newText = productText.match(rgx);
 alert(newText);

Answer 1

Use the following instead:

var rgx = /\(([^)]+)\)/;
var match = productText.match(rgx);
var newText = match && match[1];
// newText's value will be "Table 2" if there is match; null otherwise

When you have /^\(\)$/, you are actually trying to match the string "()", no more, no less. Instead, you should match, anywhere in the text, a (, store everything between it and the next ) in a capturing group ([^)]+), so that you can refer to the captured group later on with match[1].

If you want just the number, use /\(Table (\d+)\)/.
