</html>修改了 但还是不能改变行的颜色
var otr=document.getElementsByTagName("tr");
for(var i=0; i<otr.length; i++) {
otr[i].onclick=function (){this.style.background="red";
}
}
}
table 设置ID="tblMain",脚本使用我提供的，再试
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title><script type="text/javascript"> var tblMain = null;
var objRow = null;
var objOldRow = null; window.onload=function()
{
tblMain = document.getElementById("tblMain");
for (var i = 0; i < tblMain.rows.length; i++)
{
objRow = tblMain.rows[i];
objRow.onclick = OnRowClick;
}
} function OnRowClick()
{
objRow = event.srcElement.parentElement;
if (objRow != objOldRow)
{
for (var i = 0; i < objRow.cells.length; i++)
{
if (objOldRow != null)
{
objOldRow.cells[i].style.backgroundColor = "white";
}
objRow.cells[i].style.backgroundColor = "red";
}
} objOldRow = objRow;
}
</script>
</head>
