JQuery string contains check

Question

Hello,

I need to check a string to see if it contains another string.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";

What function do I use to find out if str1 contains str2?

Cheers, Thomas.

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
    alert(str2 + " found");
}
