c# - 如何隐藏字段集？

Question

fsCreditCard.Visible = false;

在一些代码隐藏的 C# 代码中工作，以隐藏在 .aspx 代码中定义的字段集 fsCreditCard，如下所示:

<fieldset id="fsCreditCard" runat="server" visible="false">
    <legend>Credit Card</legend>
        <ul style="margin:50px;font-size:16px;">
            <li>
                <u><b><a href="javascript:OpenPaymentWindow(); fsCreditCard.Visible= false; fsAfterCreditCard.Visible = true; fsPaymentOptions.Visible=false;">Click here</a></b></u> now to open the PayPal payment window and complete your payment. If you have any trouble, please make sure any pop up blockers are disabled and reload this page.<br /><br />
            </li>
        </ul>
</fieldset>

现在，当用户单击超链接“Click Here”时，“OpenPaymentWindow 实际上已被处理，但“fsCreditCard.Visible= false; fsAfterCreditCard.Visible = true;"命令未完成。它们似乎不是 javascript 命令，它们存在于 C# 代码中的其他位置。您有什么建议？

Answer 1

将显示/隐藏元素的逻辑移至 OpenPaymentWindow JavaScript 函数中并使用 jQuery 选择器，如下所示:

function OpenPaymentWindow() {
    // Logic to open payment window here

    // Show/hide DOM elements here
    $('#fsCreditCard').hide();
    $('#fsAfterCreditCard').show();
    $('#fsPaymentOptions').hide();
}
