Extract characters from a string:

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

The result of res will be:

$('.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.
