Question

I have function that is getting the width of my images in list and I need to count them all together. When I do it in foreach it brings some weird number.

This function is getting width of every element, I really don’t care about every element, just how much width they are taking together…

var listWidth = [];
$('#thumbContainer ul li').each(function(){
    listWidth.push($(this).width());
});

Not sure what you tried, but this should work:

var listWidth = 0;
$('#thumbContainer ul li').each(function(){
    listWidth += $(this).width();
});

alert( listWidth );

…or this:

var listWidth = 0;
$('#thumbContainer ul li').width(function(i,wid){ listWidth += wid; });

alert( listWidth );
