大家好，
我正在开发Web应用程序，并使用DataList Control来显示数据.
我在数据列表的ItemTemplate中放置了一个复选框(以及禁用的单选按钮).我希望当我单击复选框时，那些单选按钮将启用.
怎么可能呢?

推荐答案
您可以使用JQuery做到这一点.以下是我的工作:
< script type ="text/javascript" src ="jquery-1.6.js"></script>
< html xmlns ="http://www.w3.org/1999/xhtml">
< head runat ="server">
< script type ="text/javascript" language ="javascript">
函数SelectRBTN(chk)
{
You can do it using JQuery. Below is what I did:
<script type="text/javascript" src="jquery-1.6.js"></script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script type="text/javascript" language="javascript">
function SelectRBTN(chk)
{
(''#<％= dataList.ClientID％>'').find("input:checkbox").each(function(){
if(this == chk&& this.value ==``on''){
(''#<%=dataList.ClientID %>'').find("input:checkbox").each(function() {
if (this == chk && this.value == ''on'') {
(this).parent(``td''). children(''input:radio'').attr(''disabled''，'''');
}
});
}
</script>
</head>
< body>
< form id ="form1" runat ="server">
< asp:DataList ID ="dataList" runat ="server"
onitemcreated ="dataList_ItemCreated">
< ItemTemplate>
< asp:CheckBox ID ="chk" runat ="server" onclick ="javascript:SelectRBTN(this);"/>
< asp:RadioButton ID ="rbtn1" runat ="server" enabled ="false"/>
< asp:RadioButton ID ="rbtn2" runat ="server" enabled ="false"/>
<％#Eval(名称")％>
<％#Eval("Roll")％>
</ItemTemplate>
</asp:DataList>
</form>
</body>
</html>
(this).parent(''td'').children(''input:radio'').attr(''disabled'', '''');
}
});
}
</script>
</head>
<body >
<form id="form1" runat="server">
<asp:DataList ID="dataList" runat="server"
onitemcreated="dataList_ItemCreated" >
<ItemTemplate>
<asp:CheckBox ID="chk" runat="server" onclick="javascript:SelectRBTN(this);"/>
<asp:RadioButton ID="rbtn1" runat="server" enabled="false" />
<asp:RadioButton ID="rbtn2" runat="server" enabled="false" />
<%#Eval("Name") %>
<%#Eval("Roll")%>
</ItemTemplate>
</asp:DataList>
</form>
</body>
</html>
