大概代码 ：
<asp:Repeater ID="ReList" runat="server">
<ItemTemplate>
..
..
..
<a id="a" runat="server" href="#">
<a id="b" runat="server" href="#">...
... </ItemTemplate>
</asp:Repeater>
... <input id="pic" runat="server" type="text" />
问题：
1。 我想让 pic 值是1的时候 A就显示 B隐藏 pic 是2的时候 B显示 A隐藏
2. 具体怎么获取ID代码帮忙写下
<asp:Repeater ID="ReList" runat="server">

if($(this).val() == 1)
{
$("#testDIV > a").eq(0).css("display","none");
}
else
{
$("#testDIV > a").eq(1).css("display","none");
}
});
document.getElementById("<%=a.ClientID%>").style.display="none"
if($(this).val() == 1)
{
$("#ReList > a").eq(0).css("display","none");
}
else
{
$("#ReList > a").eq(1).css("display","none");
}
});
{
var value=$("#pic").val();
if(value=="1"){
$("#a").css("display","");
$("#b").css("display","none"); }else if(value=="2"){
$("#b").css("display","");
$("#a").css("display","none"); }
}
$("#b")都是错误的
onload="javascript:Product.PriceClassload()Product.PriceClassload=function()
{
document.getElementById("<%=a.ClientID%>").style.display="none"}
是这样么？？
$("#ReList > a").css("display", "none");
应该可以隐藏所有的 a 标签了，实在不行可以用样式名控制
报错了，说缺少对象！
不一定非要用ID，你可以用jquery的组合筛选器把a标签取出来！
<a id="a" href="#" style="display: <%= pic.Text=="1"?"":"none" %>" >
<a id="b" href="#" style="display: <%= pic.Text=="2"?"":"none" %>" >
<a id="a" href="#" style="display: <%= pic.Text=="1"?"":"none" %>" >
报错勒
//我这可是去掉了runat="server"的哦，你自己看下
public string Getur(string pic)
{
return "";
}
<%# Eval("pic").ToString().Equals("1")?"<A href ..":""%>
下面是客户端实现和服务器端实现的2种方法，直接拷贝即可运行客户端方法
