如何在asp.net中获取运行时ID

Question

I have a asp.net elements when page is run it changes its ID dynamically to add "ctl00_Content" to the ID I tried to call the ID element in this way to avoid this dynamic name

$("#<%=btnCreate.ClientID%>")

but when the page add "ctl00_" only I tried to write it as "#ctl00_MyActionMenuControl_btnCreateNew" and it works well but when I try to write it as $("#<%=MyActionMenuControl_btnCreateNew.ClientID%>") gives me error

please help

Answer 1

One way to do this as follows

<asp:Button ID="btnCreate" ClientIDMode="Static" runat="server" Text="Button" />

Javascript

<script type="text/javascript">
    var btn = $("#btnCreate");
    var btnText = $("#btnCreate").text();
    alert(btnText);
</script>

But in your case change your code as follows, it will work fine

$("#"+'<%=MyActionMenuControl_btnCreateNew.ClientID%>')

mziaulhaq was right. If you try to use server controls into client side validation/in funcationality you must use 'ClientIDMode="Static"'. It helps you to maintain the ID as Static even though it was server side control.

 <asp:Button ID="btnCreate" ClientIDMode="Static" runat="server" Text="Button" />
