var str = "Hello world!"; var res = str.substring(1,4);

$('.dep_buttons').mouseover(function(){     $(this).text().substring(0,25);     if($(this).text().length > 30) {         $(this).stop().animate({height:"150px"},150);     }     $(".dep_buttons").mouseout(function(){         $(this).stop().animate({height:"40px"},150);     }); });

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25)); 

The above will extract the text of a tag, then extract again assign it back.
