mark-my-word

// I was looking to highlight words in text nodes today and came across:
// http://bartaz.github.io/sandbox.js/jquery.highlight.html 
// http://johannburkard.de/
//
// Both seemed a little verbose so I came up with the solution below.
// Please note this has not yet been fully tested, but worked for my needs.

var words = ['words','to','mark'];

$.each(words, function(i, word){
        mark_my_word($('#content'), word);
})

function mark_my_word($elm,word){
        $.each($elm.find("*").contents().filter(function(){
                return( this.nodeType === 3 ); 
        }), function(i, node){
                $(node).replaceWith(node.data.replace(RegExp("("+word+")", "ig"), "<mark>$1</mark>"));
        });
}
