I'm having issues trying to isolate and remove the first 3 words from a string.

The string is: "LES B1 U01 1.1 Discussing what kind of job you want"

I need to make it: "1.1 Discussing what kind of job you want"

I was able to get the first word using /^([\w-]+)/

Any help would be appreciated!

PS. I'm using jQuery

To remove first three words, separated by space you can use String's split and Array's slice and join.

"LES B1 U01 1.1 Discussing what kind ...".split(' ').slice(3).join(' ');

You are on the correct track. I have created a regexp type fiddle here to show you have it works.

/^([\S]+)\s([\S]+)\s([\S]+)/g

Essentially what this does is look for any non-space character 1 or more times followed by a whitespace character then non-space 1 or more times, whitespace, then the last set of non-space characters giving you your three words.

var sentence = "LES B1 U01 1.1 Discussing what kind of job you want";
var words = sentence.split(/\s/);

words.shift(); // shift removes the first element in the array
words.shift(); // ..
words.shift(); // ..

alert(words.join(" "));

This is a way to do it.

var str = "LES B1 U01 1.1 Discussing what kind of job you want";
console.log( str.replace(/^(?:\w+\s+){3}/,'') ); 

Will output 1.1 Discussing what kind of job you want
