I have found (not written) a piece of code for a resizable div that works beautifully in firefox and IE, but in Chrome it’s very difficult to expand–it often just ignores you if you try to stretch it. I’m not even sure why this is–it’s difficult to troubleshoot.

Any hint as to why chrome is often refusing to expand this div would be nice. Try for yourself.

#mydiv{
    position:relative;
    top:0px;
    left:0px;
    width:250px;
    border: 1px solid #808080;
    overflow: auto;
}

#statusbar{
    cursor: s-resize;
    position:relative;
    display:block;
    background-color: #c0c0c0;
    font-size: 0px;
    margin:0;
    height:5px;
    border: 1px solid #808080;
    padding:0;
    width: 250px;
}

scripts:

var curHeight=0;
var curMousePos=0;
var mouseStatus='up';
var curEvent;

//this function gets the original div height
function setPos(e){
    curEvent=(typeof event=='undefined'?e:event);
    mouseStatus='down';
    //gets position of click
    curMousePos=curEvent.clientY;
    curHeight=parseInt(document.getElementById('mydiv').style.height.split('p')[0]);
}

//this changes the height of the div while the mouse button is depressed
function getPos(e){
    if(mouseStatus=='down'){
        curEvent=(typeof event=='undefined'?e:event);
        //how many px to update the div? difference of previous and current positions
        var pxMove=parseInt(curEvent.clientY-curMousePos);
        var newHeight=parseInt(curHeight+pxMove);
        //conditional to set minimum height to 5
        newHeight=(newHeight<5?5:newHeight);
        //set the new height of the div

        document.getElementById('mydiv').style.height=newHeight+'px';
    }
}

finally the HTML:

    <div>
    <div id="mydiv" style="height: 250px; min-height:150px; ">
        <div></div>
    </div>
    <div onmousedown="setPos(event)" onmouseup="mouseStatus='up'" id="statusbar"></div>
</div>

EDIT: seems chrome supports the CSS3 property RESIZE. This is awesome and totally better than the JS approach I used. Still, I wish the above code worked on chrome as it does on FF/IE so I wouldn’t have to check for the browser type.

    <!doctype html>

<html>
    <head>
        <script>
            window.onload = function () {
                var div = document.getElementById ("statusBar");

                var press = false;

                div.onmousedown = function () {
                    press = true;

                    return false;
                }

                this.onmousemove = function (event) {
                    event = event ? event : window.event;

                    if (press === true) {
                        div.style.height = event.clientY + "px";
                    }
                }

                this.onmouseup = function () {
                    press = false;
                }
            }
