There is markup as below,

<div class="content">Lorem</div>
<div class="content">Lorem Iorem Lorem Iorem Lorem Iorem Lorem Iorem Lorem IoremLorem Iorem Lorem Iorem Lorem Iorem</div>
<div class="content">Lorem</div>
<div class="content">Lorem</div>

If content have scroll bar, then it should add class to that div like "scroll-image".

Height can be different for DIVs. Any jQuery solution for this.

Answer 1

(function($) {
    $.fn.hasScrollBar = function() {
        return this.get(0).scrollHeight > this.height();
    }
})(jQuery);

$('#my_div1').hasScrollBar(); // returns true if there's a `vertical` scrollbar, false otherwise..

Taken from How can I check if a scrollbar is visible?

Answer 2

You need to compare scrollHeight with height of the element like this:

$('.content').each(function(){
  if ($(this)[0].scrollHeight > $(this).height()) {
    $(this).addClass('scroll-image');
  }
});

As esailija said, duplicate of: Detecting presence of a scroll bar in a DIV using jQuery?

The solution there was the following

var div= document.getElementById('something'); // need real DOM Node, not jQuery wrapper
var hasVerticalScrollbar= div.scrollHeight>div.clientHeight;
var hasHorizontalScrollbar= div.scrollWidth>div.clientWidth;
