<script type="text/javascript">
function IniEvent() {
var tbl = document.getElementById("tblMain");
var trs = tbl.getElementsByTagName("tr");
for (var i = 0; i < trs.length; i++) {
trs[i].onclick = TrOnClick;
}
}
function TrOnClick() {
var tbl = document.getElementById("tblMain");
var trs = tbl.getElementsByTagName("tr");
for (var i = 0; i < trs.length; i++) {
if (trs[i] == this) { //判断是不是当前选择的行
trs[i].style.background = "yellow";
}
else {
trs[i].style.background = "white";
}
}
}
</script>
</head>
<body onload="IniEvent()">
