javascript - Alert filtered words using Jquery -

i have this jsfiddle.

i have words which, when user types them, needs alerted user. right when type line, example, i love ants alerts me full line i love ants, want ants alerted me. (in example ants word need filtered. refer jsfiddle.)

var filter = ['ants', 'words'],     reg = new regexp("(" + filter.join("|") + ")", "g");  $('#texta').keyup(function(){     $("#dest").html(         $(this).val().replace(reg, "<mark>$1</mark>")         );    if(reg.test($(this).val())==true)    {        alert($(this).val());    }        }); 

you can change show matched part using this:

alert($(this).val().match(reg)); 

here's jsfiddle.

if want separate alert each match have loop.

edit: here's version alerts once each time user types word in list.

edit: , here's version demonstrates optional use of regexes instead of words. note slashes must double-escaped. so, example, match ants not pants, add \\bants\\b word list. example, demo match \bb..\b (so, bar, baz, etc., not batters).
