我是一个PHP初学者。所以我正在做一个小任务，我想做一个表格，里面有MCQS，上面有一个10分钟的倒计时计时器。当倒数计时器上升时，表单应该过期，并应该自动显示结果。我已经使表单编码如下，但我不知道该怎么做，这样我就可以在这个代码中添加定时器，使表单过期，并显示正确选择的答案的结果。

您需要JavaScript来实现这种行为，假设您使用以下JS:
window.setTimeout(function() {
document.forms['form_name'].submit();
}, 2000);
form_name应该是表单的名称。即
<form name = "form_name" ... >
</form>
这将以毫秒(2秒)为单位延迟发布，然后它应该带你到另一个可以显示正确答案的页面。
