asp.net中怎样用Javascript控制RequiredFieldValidator控件什么时候启用，什么时候不启用验证？

Enable/Disable RequiredFieldValidator with Javascript

 

document.getElementById("requiredfieldvalidatorid").enabled = false;

 

<asp:DropDownList ID="ddlServiceName" runat="server" onchange='var DateValidator = document.all ? document.all["DateValidator "] : document.getElementById("DateValidator ");DateValidator .enabled = false;'></asp:DropDownList>
