Question

http://jsfiddle.net/kM8xE/2/

If I have the divs
​

<div class="value">15</div>
<div class="value2">20</div>​

and jQuery

var actual = $(".value").html();
var comparison = $(".value2").html();

how can i add class .isbetween to .value2 if it’s html value is between +/-10 of the html for .value ie. for this eg. a value between 5 and 25.

I am not too good but i have tried and it doesn’t work.

if(parseInt(actual)-10 <= parseInt(comparison) <= parseInt(actual)+10){
$(".value2").addClass("isbetween");
}

Answer 1

 if (Math.abs(actual - comparison) <= 10) {
    //they're within 10
 }
