Passing a textbox value to javascript on key up function

Question

Here i have passed the text control to the java script function but i just want to pass the value of the text box to the java script function instead on onkeyup.

function Changed(textControl) {
    var _txtEmpName = document.getElementById('<%=txtEmpName.ClientID%>');

    var _EnteredString = _txtEmpName.value;

<asp:TextBox
        ID="txtEmpName" runat="server" onkeyup="javascript: Changed( this );"></asp:TextBox>

See this url it's working nice for me... [How to call javascript function on keyup event for asp:TextBox][1] [1]: stackoverflow.com/questions/5607313/… — csharpbd

If you want to pass the value instead, simply do:

<asp:TextBox ID="txtEmpName" runat="server" 
 onkeyup="javascript: Changed( this.value );"></asp:TextBox>

Not sure if I understand, but if you want to pass the value you should use this.value instead of just this

<asp:TextBox ID="txtEmpName" runat="server" onkeyup="Changed(this.value)">
</asp:TextBox>

Maybe use onblur instead of onkeyup? You will be calling that function with every keystroke, is that something you really want to do?
