Question

CSS:

 .blue
    {
     width:200px;
     height:200px;
     background-color:blue;
     color:#000000;
     overflow:auto;
    }

JavaScript:

function addChar() {
    $('.blue').append('some text  ');
}

HTML:

<div id='blue1' class="blue"></div><br />
<a href='javascript:void(0)' onclick='addChar()'>Add</a>

div id='blue1' has overflow property set to auto. I want to detect overflow when it happens.

Answer 1

$.fn.HasScrollBar = function() {
    //note: clientHeight= height of holder
    //scrollHeight= we have content till this height
    var _elm = $(this)[0];
    var _hasScrollBar = false; 
    if ((_elm.clientHeight < _elm.scrollHeight) || (_elm.clientWidth < _elm.scrollWidth)) {
        _hasScrollBar = true;
    }
    return _hasScrollBar;
}
