jquery实现拖拽调整Div大小

            var startX = event.clientX + scroll.x;
            var startY = event.clientY + scroll.y;
            _startX = parseInt(startX);
            _startY = parseInt(startY);
            if (document.addEventListener) {
                document.addEventListener(“mousemove”, moveHandler, true);
                document.addEventListener(“mouseup”, upHandler, true);
            } else if (document.attachEvent) {
                target.setCapture();
                target.attachEvent(“onlosecapeture”, upHandler);
                target.attachEvent(“onmouseup”, upHandler);
                target.attachEvent(“onmousemove”, moveHandler);
            }
            if (event.stopPropagation) {
                event.stopPropagation();
            } else {
                event.cancelBubble = true;
            }
            if (event.preventDefault) {
                event.preventDefault();
            } else {
                event.returnValue = false;
            }
        }
        function moveHandler(e) {
            if (!e) e = window.event;
            var w, h;
            var startX = parseInt(e.clientX + scroll.x);
            var startY = parseInt(e.clientY + scroll.y);
