gridview 鼠标点击行变色 等实现

<script type="text/javascript">
var prevselitem = null;
function selectx(row) {
if (prevselitem != null) {
prevselitem.style.backgroundColor = '#ffffff';
}
row.style.backgroundColor = '#aaaaaa';
prevselitem = row;
}
</script>

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//e.Row.Attributes.Add("onmouseover", "if(this!=prevselitem){this.style.backgroundColor='#Efefef'}");//当鼠标停留时更改背景色
//e.Row.Attributes.Add("onmouseout", "if(this!=prevselitem){this.style.backgroundColor='#ffffff'}");//当鼠标移开时还原背景色
e.Row.Attributes.Add("onclick", e.Row.ClientID.ToString() + ".checked=true;selectx(this)");//点击行变色
//e.Row.Attributes["style"] = "Cursor:hand"; //设置悬浮鼠标指针形状为"小手"
//  GridView1.HeaderRow.Cells[10].Visible = false;
// e.Row.Cells[10].Visible = false;//隐藏选择按钮
//String evt = Page.ClientScript.GetPostBackClientHyperlink(sender as System.Web.UI.WebControls.GridView, "Select$" + e.Row.RowIndex.ToString());
// e.Row.Attributes.Add("onclick", evt);//执行选择行GridView1_SelectedIndexChanged事件
}
}
