postback of button click not working with <%= %>

Question

I am using the below method of calling the click event of buttton in javascript.

__doPostBack('<%= btn_hid.UniqueID %>');

but this is leading me to another error

The Controls collection cannot be modified because the control contains code blocks (ie <% ... %>).

can you please suggest me any other way to call the click event of button in javascript during postback??

Answer 1

您可以尝试使用基于GetElementById方法的click method方法

document.GetElementById('<%= btn_hid.ClientID %>').click()
