asp.net获取控件ID
- HTML code
<html xmlns="http://www.w3.org/1999/xhtml" > <body onload="init()"> <form id="Form1" method="post" runat="server" clientidmodel="static" > <FONT face="宋体"> <%--<a href="www.baidu.com" ">sss</a>--%> <asp:DataList id="DataList1" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 0px" runat="server" RepeatDirection="Horizontal" ShowHeader="False" ShowFooter="False" RepeatLayout="Flow"> <ItemTemplate> <asp:Image ID="Image1" runat="server" Height="16px" ></asp:Image> <asp:HyperLink id="HyperLink1" runat="server">[HyperLink1]</asp:HyperLink> </ItemTemplate></asp:DataList> </FONT> <script> function init() { var hy=document.getElementById("<%=HyperLink1.ClientID%>"); alert(hy); } </script> </form> </body></html>为什么获取不到Hyperlink1的控件iD，alert为null
[解决办法]
HyperLink 生成的html 是a标记 用下面的方法去找。
var inputs = document.getElementById("<%=DataList1.ClientID%>").getElementsByTagName("a");
for(var i=0;i<inputs;i++)
{
}
