如何在.aspx页的客户端中获取标签控件的值 [英] How to get Value of Lable control in Client Side of .aspx Page

问题描述

亲爱的先生
我正在获取TextBox的Value，它工作正常...

Dear Sir
I am using to get Value of TextBox, it is working fine ...

var ID=document.getElementById("<%=txtipdregno.ClientID%>").value;

但是对于Lable，它不起作用，请对其进行修改.
也可以在Visible ="False"条件下获取Value吗?

But for Lable it is not working, Please modify it.
Also is it possible to get Value in Visible="False" condition ?

推荐答案

否，当您在ASPX页面中设置Visible = False时，.Net不会呈现完全没有控件，因此您无法在客户端获得它.如果需要访问隐藏"控件客户端，则必须使用style ="visibility:hidden"，以便控件位于客户端.

No, when you set Visible=False in the ASPX page, .Net does not render the control at all so you cannot get it on the client side. If you need to access a "hidden" control client side you have to use style="visibility: hidden" instead so that the control is on the client side.

var ID = document. getElementById(<％= LblID.ClientID％>").innerHTML;

var ID=document.getElementById("<%=LblID.ClientID%>").innerHTML;
