asp.net 2.0下gridview中加亮移动行

   看到老外的blog,说asp.net 2.0下的gridview中，当用户在gridview中用鼠标从上到下扫描各行时，起到加亮显示每次移动过的行的一个效果，
用javascript写的，还算简单，记录之
  <asp:repeater >

然后是javascript实现CSS效果

function Repeater_selectRow(row, ProductId)
{
var hdn=document.Form1.hdnProductID;
hdn.value = ProductId;
if (lastRowSelected != row)
{
if (lastRowSelected != null)
{
lastRowSelected.style.backgroundColor = originalColor;
lastRowSelected.style.color = 'Black'
lastRowSelected.style.fontWeight = 'normal';
}
originalColor = row.style.backgroundColor
row.style.backgroundColor = 'BLACK'
row.style.color = 'White'
row.style.fontWeight = 'normal'
lastRowSelected = row;
}
}
function Repeater_mouseHover(row)
{
row.style.cursor = 'hand';
}
