Javascript regExp - find brackets

Question

I can't figure out how to search for a string containing something like "[1]", for some reason this doesn't work:

var regExp = '/\[[1-9]\]/';
var search = string.search(regExp); // returns -1

I've searched all over for a solution but can't find anything...

Answer 1

Try it without the '

var regExp = /\[[1-9]\]/;
var search = string.search(regExp);

Answer 2

I think it's the way you're actually attempting to match it. Try this:

string="something[1]";
if(string.match(/\[[1-9]\]/gi)) alert("Your string has brackets with a number inside!"); //Alerts correctly
