javascript - 为什么 ASP 经典 Select Case 分支中不会弹出 javascript 警报？

Question

为什么 JavaScript 警报不会在 ASP 经典 Select Case 分支中弹出？当我放入 Response.End 语句并运行结帐过程时，JavaScript 警报会执行其操作......但是当我将它们取出时，它们会立即跟随重定向......警报不会弹出。知道为什么吗？

If strResponse <> "000" Then
Select Case strResponse
    Case "701"
        %>
        <script type="text/javascript">
            alert("The customer is under 18 years of age based upon the date of birth.");
        </script>
        <%
        'Response.End
        Response.Redirect strRedirectCheckout
    Case "702"
        %>
        <script type="text/javascript">
            alert("The billing address is outside the United States.");
        </script>
        <%
        'Response.End
        Response.Redirect strRedirectCheckout
    Case "707"
        %>
        <script type="text/javascript">
            alert("The account holder does not have sufficient credit available for the transaction amount.");
        </script>
        <%
        'Response.End
        Response.Redirect strRedirectCheckout
    Case Else
        %>
        <script type="text/javascript">
            alert("Unable to obtain an authorization\nClick OK to be redirected back to checkout and please choose another form of payment");
        </script>
        <%
        'Response.End
        Response.Redirect strRedirectCheckout
End Select

Else ' if strResponse does == '000'; SUCCESS!!!

因为 Response.Redirect 会向浏览器发送一条消息，以开始导航到指示的页面。如果您希望他们首先看到弹出窗口，则在警报之后只需留在 JavaScript 中并使用 document.location.href=.....
