If you set the Visible property to false; typically in .net the control will not be rendered in the HTML output after the page is processed. Therefore as far as jQuery is concerned, the button does not exist.
如果您将 Visible 属性设置为 false；通常在 .net 中，处理页面后，控件不会在 HTML 输出中呈现。因此，就 jQuery 而言，该按钮不存在。
You can do a View Source on the page to verify this.
您可以在页面上执行查看源代码来验证这一点。
If you want to do this, instead of using the Visible property, you can do something like:
如果要执行此操作，可以不使用 Visible 属性，而是执行以下操作：
<asp:Button ID="HiddenButtonID" runat="server" style="visibility: hidden; display: none;" />
Then you can using jQuery to click button as :
然后您可以使用 jQuery 单击按钮为：
$("#HiddenButtonID").click(); //Remember that in button, you must set ClientIDMode = "static"
or
或者
$("#<%=HiddenButtonID.ClientID%>").Click();
