jquery Doing Simple Math? -

-

i have little div this:

<div id="counter">2</div>

i'd use jquery either subtract or add let 1, resulting in 3 or 1...

is there way in jquery this? convert string int maybe?

$('#counter').text(function(i,txt) { return parseint(txt, 10) + 1; });

example addition: http://jsfiddle.net/2ubmy/

example subtraction: http://jsfiddle.net/2ubmy/1/

to add check negative, this:

$('#counter').text(function(i,txt) {     var result = parseint(txt, 10) - 1;     return (result > 0) ? result : 0;  });
