javascript - 我正在编写代码进行在线测试，在自动提交时遇到了问题

Question

我用过 PHP、JS、Mysql 和 Html 除了自动提交和计时器外，一切都在工作。

20 分钟后，它应该使用用户选择的选项自动提交并存储在 mysql 中。弹出窗口“超时并告诉您的答案已提交”。

但它弹出时间消息而不是自动提交和执行 php 代码以将值存储在 mysql 中。

<html>
<head>
</head>
<body>

<form action="" method="REQUEST">



<b>Enter Username:</b><input type="text" name="username" value=""/><br>

<b>Enter Password: </b><input type="password" name="password" value=""/><br>

<input type="submit" value="submit" name="submit"/>
<input type="reset" value="reset" name="reset"/>

</form>

<?php


if (isset($_REQUEST['submit'])) 
{

$username=$_REQUEST['username'];
$password=$_REQUEST['password'];

mysql_connect("localhost", "root", "") or die(mysql_error()); 

mysql_select_db("demo") or die(mysql_error()); 

$result=mysql_query("select * from employees where name='$username' and pass='$password'") 
 or die(mysql_error()); 


if(mysql_num_rows($result)==0)
{
print "<br/>";
print "<b>Incorrect Username/Password!!!</b>";
}
else
{
print "<br/>";
print "<b>Login successful!!!</b><br/><br/>";
print "<script>window.close()</script>";
print "<a href=hello.php><script>window.open('hello.php')</script></a>";

我希望以下代码可以帮助您自动提交表单。

只需将此代码复制粘贴到新页面并运行即可。

您会在 20 分钟后看到提交按钮将自动单击并显示一条消息。

从这个概念你不能在特定时间后自动提交

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" 
                 type="text/javascript"></script>

<script>

var submitForm = function() {
    $("input[name='submit']").click();
}

function waitSpecificTime(minute)
{
    setTimeout(submitForm, 1000*60*minute) //20 min
}

waitSpecificTime(20); // 20 min

</script>

<input type="submit" value="submit" name="submit" onclick="alert('test');"/>
