Question

i have element which have misc height. I need to add some margin-top to other element according as this first block. I was used for this action jQuery height property but it’s does’t work. Can you help me?

This is my code:

$(document).ready(function(){
    if ($('.post_discussion_header').height(79) + 'px'){
        $('.no_0').css('margin-top','110px');
        }
    });
});

TIA.

Answer 1

Your if statement is wrong, it should be

   if ($('.post_discussion_header').height() == 79){

however you may consider using offset height which returns the height of an element, including borders and padding if any, but not margins https://developer.mozilla.org/en/DOM/element.offsetHeight

   if (parseInt($('.post_discussion_header')[0].offsetHeight,10) == 79){ 

EDIT: added parseInt to convert the “79px” to 79 for comparison http://www.w3schools.com/jsref/jsref_parseInt.asp

Also you have one too many }); in your code. Line 5 should just be }
