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.
