IF doesn't work inside each()

any if statement I put inside this function refuses to work.

The statement is true for some elements with this class and false for some, however all ignore it

(This is very stripped functionality just to locate the problem...)

$(".bought").each(function(index) {
Height = $(this).css("height")
    if (Height > 19) {
        alert(Height);
    }
});

this does work:

$(".bought").each(function(index) {
Height = $(this).css("height")
    alert(Height);
});

$(".bought").each(function(index) {
    thisHeight = $(this).height()
    if (thisHeight > 19) {
        alert(thisHeight);
    }
});

That works! http://jsfiddle.net/NmHb3/

$(this).css("height") returns string...you need to parse this in int before applying comparison..

 Height = parseInt($(this).css("height"),10)
if (Height > 19) {         alert(Height);     }

Height is returned as a string. The comparision is actually "19" > 19 which yields false.

Try converting it to an integer:

if (parseInt(Height) > 19) {
// ...
}

The below code which you have used returns 'px' appended to the result so you can't compare it to '19'

Height = $(this).css("height")

Parse it like this and let us know how you get on :)

parseInt($(this).css('height'), 10);
