Jquery: Replace string with only the first word

Question

I have been looking everywhere and can't find this..

I got a string and I want to replace the whole string with only the first word.

for example:

String: "hello world"

New String: "hello"

Thanks in advance!

Answer 1

var s = "hello world"
s = s.replace(/(\w+).*/,"$1");

that'll do it.

Answer 2

The quickest and easiest way is to split the string into an array based on spaces, then set it to be the first one.

var theString = "hello world";
theString = theString.split(" ")[0];
alert(theString); // alerts "hello"
