<script>
function doAlert(source){
window.alert(source.id);
}
function doTest(){
var menuCount;
menuCount=window.tbl.rows.length;
for(var i=0;i<menuCount;i++)
{
window.tbl.rows(i).attachEvent("onMouseMove",doAlert(this)); //这样写不行，请教怎么写
}
}
</script>
<body onload="doTest();">
<table id="tbl" >
<tr id="tr1">
