关于div拖拽，有经验看看
[code=JScript][/code]
new Draggable("div1",{revert:true});
new Draggable("div2",{revert:true});
new Draggable("div3",{revert:true});
new Draggable("div4",{revert:true});
new Draggable("div5",{revert:true});
new Draggable("div6",{revert:true});
new Draggable("div7",{revert:true});
new Draggable("div8",{revert:true});
new Draggable("div9",{revert:true});
new Draggable("div10",{revert:true});
Droppables.add("dustbox", {
accept:"item-area",
onDrop: function(draggable, droppable) {
alert('ドロップされたのは、' + draggable.firstChild.nodeName);
}
});
function ondrop(draggable, droppable){
var child = droppable.firstChild;
droppable.removeChild(child);
var parent = droppable.parentNode;
parent.appendChild(child);
droppable.appendChild(draggable);
}
后台的.js文件应该都正确，现在已经能够实现div的拖动，但放置的时候，不执行
function ondrop而且draggable.firstChild.nodeValue也取不到值。。。
说得也不明白，希望有经验的来分析下。。。。

/*<层的拖动>*/
var ms=0;
function dragDiv(obj){
if(event.srcElement.type!='text')//选中TEXT控件 不拖动
{
ms=obj;
event.srcElement.setCapture();
x=document.all(ms).style.pixelLeft-event.x;
y=document.all(ms).style.pixelTop-event.y;
}
}
function document.onmousemove(){
if(ms){
document.all(ms).style.pixelLeft=x+event.x;
document.all(ms).style.pixelTop=y+event.y;
}
}
function document.onmouseup(){
if(ms){
event.srcElement.releaseCapture();
ms=0;
}
}
/*</层的拖动>*/
使用方法
<div id="div1" onmousedown="dragDiv('div1')" >aaaaaa</div>

/** * Drag.js: drag absolutely positioned HTML elements. * * This module defines a single drag( ) function that is designed to be called * from an onmousedown event handler. Subsequent mousemove events will * move the specified element. A mouseup event will terminate the drag. * If the element is dragged off the screen, the window does not scroll. * This implementation works with both the DOM Level 2 event model and the * IE event model. * * Arguments: * * elementToDrag: the element that received the mousedown event or * some containing element. It must be absolutely positioned. Its * style.left and style.top values will be changed based on the user's * drag. * * event: the Event object for the mousedown event. **/function drag(elementToDrag, event) { // The mouse position (in window coordinates) // at which the drag begins var startX = event.clientX, startY = event.clientY; // The original position (in document coordinates) of the // element that is going to be dragged.
