Getting ID from asp.net runat server in jQuery

javascript jquery asp.net runatserver

I'm trying make some stuff in jQuery using ASP.NET. But the ID from runat="server" is not the same as the id used in HTML.

I used to use this to get the ID from this situation:

$("#<%=txtTest.ClientID%>").val();

But in this case, it does not work. I'm clueless as to why.

Javascript

/* Modal */
function contatoModal() {
    //alert("Test");
    alert($("#<%=txtTest.ClientID%>").val());
}

HTML

< input runat="server" id="txtTest" value="test" />

Any tips?

<%= txtTest.ClientID %> should work but not in a separate javascript file where server side scripts do not execute. Another possibility is to use a class selector:

<input runat="server" id="txtTest" value="test" class="txtTest" />

and then:

var value = $('.txtTest').val();
