推荐答案

只需重写dragstart消息处理程序以及selectstart...
在函数中取消事件...

Simply override the "dragstart" message handler as well as the "selectstart"... While in the function cancel the event...

<script type="text/ecmascript>
window.addEventListener("dragstart", function(fEventObject){ CancelEvent(fEventObject); } );
window.addEventListener("selectstart", function(fEventObject){ CancelEvent(fEventObject); } );

function CancelEvent(fEventObject) 
{
   if (fEventObject.preventDefault) fEventObject.preventDefault();
   if (fEventObject.cancel != null) fEventObject.cancel = true;
}

</script>
