Question

I am trying to enable and disable a required field validator using javascript but keep getting the error message ValidatorEnable is not defined. PLease find code below, any help would be great.

ASP.Net

<asp:RequiredFieldValidator EnableClientScript="True"  Display="None" ID="rfvMostRecentEmployer" ControlToValidate="txtMostRecentEmployer" runat="server" ErrorMessage="Most recent employer title is a required field"></asp:RequiredFieldValidator>

Javascript

var validatorMostRecentEmployer = document.getElementById('<%= rfvMostRecentEmployer.ClientID %>');

ValidatorEnable(validatorMostRecentEmployer, !hasCv);

Code Behind

protected void Page_Load(object sender, EventArgs e)
{
    rblCV.Attributes.Add("onClick", string.Format("ShowCvOptions();"));
    ...
}

Answer 1

Make sure that function ValidatorEnable is placed before calling from any other place.
