How to tell if a string contains a certain character in javascript?

Suppose I have a string in variable ex. var name="Stackoverflow". I want to check in this string if 'z' is exist or not? How can I check this? I don't want to find index or anything else I just want to check if value z is exist or not.

Suppose with code. I have a variable.

var deleteboxvalue = "1111111111111111111111"; if(!deleteboxvalue.indexOf('z') >= 0){ alert("0 not exist"); return false; }

You can use indexOf like this:

var name = "Stackoverflow" var charExists = (name.indexOf('z') >= 0) ? true : false; alert(charExists);

Or just (as pointed out by @Felix Kling):

var charExists = (name.indexOf('z') >= 0);
