推荐答案
这不是获取id的合适方式。 id
This is not the appropriate way of getting id. The id
ctl00_MainContent_checkList1_ctrl1_lblID
是服务器生成的id。它可以在不同的服务器上更改。所以你应该做以下步骤
is server generated id. It could change on different servers. So you should do the following steps
var result = document.getElementById('<%=CHeckList.ClientID %>').value;
在Above<%= CHeckList.ClientID%>你必须写下你的标签ID。
In the Above <%=CHeckList.ClientID%> you have to write your label id.
