Using javascript I want to remove all the extra white spac

Answer 1

This works nicely:

function normalizeWS(s) {
    s = s.match(/\S+/g);
    return s ? s.join(' ') : '';
}

• trims leading whitespace
• trims trailing whitespace
• normalizes tabs, newlines, and multiple spaces to a single regular space
