repeater隔行换色与鼠标停留在上面达到变色效果

<tr align="center" class="list_L01" style='background-color: <%#(Container.ItemIndex%2==0)?"#FFFFF;":"#fcf3f4"%>' onmouseover="change_colorOver(this)" onmouseout="change_colorOut(this)"></tr> 
 
 代码如下:

<input type="hidden" id="colorName" value="1" /> //隐藏域定义 
function change_colorOver(e) { 
var oldColor = e.style.backgroundColor; 
document.getElementById("colorName").value = oldColor; 
e.style.backgroundColor = "#b9bace"; 
} 
function change_colorOut(e) { 
e.style.backgroundColor = document.getElementById("colorName").value; 
}
