推荐答案

您必须使用母版页或用户控件.
服务器控件有时在呈现时会获得不同的控件ID.

两种选择:
1.在渲染的页面上，执行视图源.找到控件ID并在JS中使用该ID
或
2.在JS中使用如下代码:

You must be using master page or a user control.
Server controls while getting rendered at times gets a different control ID.

Two options:
1. On rendered page, do a view source. Find the control id and use that one in JS
OR
2. Use something like this in JS:

var ele = document.getElementById(''<%= BSC_FullScreen.ClientID %>'');
