代碼 如下：<ul><li><a onmouseOver="mouseOver()" onmouseOut="mouseOut()">a<img src="1.png" style="position:absolute; top:-149;x=1;" id="divP" /></a><li><li><a onmouseOver="mouseOver()" onmouseOut="mouseOut()">b<img src="1.png" style="position:absolute; top:-149;x=2;" id="divP1" /></a><li></ul><script type="text/javascript">function mouseOver(){var d=(divP1.style.x);confirm(d);//用confirm 獲取x的值為2 是對的switch (d)//為什么switch 就獲取不到{case 1:confirm("1");breakcase 2:confirm("2");breakdefault:confirm("都不是");}} </script>為什么confirm獲取的到 而switch 卻獲取不到
