从后面的代码调用JavaScript时如何设置返回值

Question

I have a link button as below

<atoms:StoreLink Visible="<%# !ECommUtilities.HideTopSubmitOrderButtonCountries  %>"   OnServerClick="Continue_Clicked" Caption="<%# CheckoutCaption %>" localefile="ECOMM_CAPTION" runat="server" ID="_continue" AuthEnabled="false" OnClientClick="<%# GetVerifyIovationMethodNam %>" />

my Javascript function is

function preventDuobleClickEvent(element) {
            alert('Prevent');
            if (!isSubmit) {
                isSubmit = true;
                element.disabled = true;
                return true;
            }
            else {
                alert('elseCond');
                return false;
            }
        }

now how can i make so that my Linkbutton client click is expecting a return

I tried this It did not work

 <atoms:StoreLink Visible="<%# !ECommUtilities.HideTopSubmitOrderButtonCountries  %>"   OnServerClick="Continue_Clicked" Caption="<%# CheckoutCaption %>" localefile="ECOMM_CAPTION" runat="server" ID="_continue" AuthEnabled="false" OnClientClick="return<%# GetVerifyIovationMethodNam %>" />

The easies way is to set the OnClientClick value from code behind since it looks like you want to use a variable as a return value for javascript. Here is an example.

<asp:Button ID="Button1" runat="server" Text="Button" />

And then in code behind:

Button1.OnClientClick = "return preventDuobleClickEvent('" + GetVerifyIovationMethodNam + "')";
