推荐答案

ASP.NET Literal控件本身不插入任何HTML到网页。

An ASP.NET Literal control does not by itself insert any HTML into a webpage. Your Literal control is a placeholder for text or HTML you will set in your code behind.

您应该将文字封装在DIV或SPAN中，并赋予ID和引用JavaScript中的DIV或SPAN

You should wrap your literal in a DIV or SPAN and give that an ID and reference that DIV or SPAN in the JavaScript

WebForm：

<span id="yourId"><asp:Literal  ID="lblPerInstanceListing" runat="server"></asp:Literal></span>

JavaScript：
由此代码解决。 >

JavaScript: Solved by this code.

var value= document.getElementById('yourId').innerText;
