c# - 澄清暂时禁用提交按钮几秒钟，然后重新启用它？

Question

这与提出的另一个问题类似，但表单不会提交。

基本上，我在这里尝试实现的是，一旦用户单击“提交”btn，该btn就会被禁用，直到页面重定向，以避免用户多次单击提交btn。

用户重定向到的页面将不会显示表单中的信息。在我介绍禁用和启用功能之前，它确实可以正常工作。

提供的代码确实禁用了 btn，甚至将文本更改为“正在提交”，但不会重定向到摘要页面，甚至当我通过选项卡导航到摘要页面时，信息也不存在。非常感谢任何帮助...

Answer 1

您需要更改脚本才能执行以下操作:

function disable() {
    x = document.getElementById("submit");
    x.form.submit();
    x.disabled = true;
    x.textContent = "Submitting...";
    setTimeout(enable, 5000);
}

function enable() {
    x = document.getElementById("submit");
    x.disabled = false;
    x.textContent = " Submit";
}

然而，禁用该按钮可能会导致回发失败。
