JS: Wrap Terms With...

gistfile1.js

/*
 * Take a string and wrap any terms with some container (like <span>)
 * Nothing complicated. It splits a string on ',' (comma) and 'and', and adds the desired wrapper around the resulting terms.
 */

​var str = 'Web Developer and Front-End Engineer and All around cool guy';
    
String.prototype.wrapTermsWith = function(wrap) {
    var delimiters = [',', ' and '],
        wrapper = wrap.split('><'),
        start = wrapper[0] + '>',
        end = '<' + wrapper[1],
        newStr = start + this;
    
   for (var i = 0; i < delimiters.length; i++) {
        newStr = newStr.split(delimiters[i]).join(end + delimiters[i] + start);       
    }
    return newStr + end;

var newString = str.wrapTermsWith('<span></span>');    

$('#job-title').html(newString);​
