Extract characters from a string:

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

The result of res will be:

ell 

$('.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.
