jQuery在内容页面的服务器控件上不起作用

Question

i am having a TextBox txt on a content page. when i try this

$(function(){
$("#txt").focus(function(){alert("abcd"); });
});

it doesn't work. It's working if i am using it on simple .aspx page with no master page.

Answer 1

如果"#txt"是<asp:textbox />控件，则在呈现页面时它将获得客户端ID，要选择asp.net控件，您需要执行$("[id*='txt']")

Answer 2

View the HTML source. I think the most likely problem is the renaming of the controls by prepending the content section's id. You can change this with the ClientIDMode property:

<asp:TextBox ID="txt" runat="server" ClientIDMode="static"/>
