ie中禁止鼠标右键的具体做法：
在网页源码和间加入代码如下：
leftmargin=0
topmargin=0
onmousemove='hidemenu()'
oncontextmenu="return
false"
ondragstart="return
false"
onselectstart
="return
false"
onselect="document.selection.empty()"
oncopy="document.selection.empty()"
onbeforecopy="return
false"
onmouseup="document.selection.empty()">
