我正在尝试为我的网站创建一个注册表单，在那里它要求用户输入一次密码，当他们点击提交时，会弹出一个JavaScript框并再次向用户询问并检查旧框和如果它们不相同，它将保留在加入页面上并告诉它们密码不匹配。我该怎么做呢？
这是我的HTML文档：
<h2>New Account Registration.</h2>
<table width="600" cellpadding="1" style="text-align:center;">
<form action="join.php" method="get" >
<tr>
<td colspan="1"><font color="#FF0000"></font></td>
</tr>
<tr>
<td>Company Name:</td>
</tr>
<tr>
<td><input style="background-color: #FFF;" name="companys_name" type="text" placeholder="Google" required /></td>
</tr>
<tr>
<td>First Name:</td>
</tr>
<tr>
<td ><input style="background-color: #FFF;" name="admin_first_name" type="text" placeholder="John" required />
</td>
</tr>
<tr>
<td>Last Name: </td>
</tr>
<tr>
<td>
<input style="background-color: #FFF;" name="admin_last_name" type="text" placeholder="Doe" required />
</td>
</tr>
<tr>
<td>Phone Number:</td>
</tr>
<tr>
<td><input style="background-color: #FFF;" type="tel" name="admin_phone" pattern="[0-9]{3}-?[0-9]{3}-?[0-9]{4}" required placeholder="123-123-1231"></td>
</tr>
<tr>
<td>Website: </td>
</tr>
<tr>
<td><input style="background-color: #FFF;" type="url" id="orderWebsite" placeholder="http://domain.com" /></td>
</tr>
<tr>
<td>Email: </td>
</tr>
<tr>
<td><input style="background-color: #FFF;" type="email" id="orderEmail" placeholder="name@domain.com" required /></td>
</tr>
<tr>
<td> Password: </td>
</tr>
<tr>
<td> <input style="background-color: #FFF;" name="admin_password" type="password" required />
</td>
</tr>
<tr>
<td><input type="submit" name="Submit" value="Register!" onclick="register()" /></td>
</tr>
</form>
</table>
这是它连接到的PHP页面：
<?php
$errorMsg = "";
// First we check to see if the form has been submitted
if (isset($_POST['companys_name'])){
//Connect to the database through our include
include_once "connect_to_mysql.php";
// Filter the posted variables
$companys_name = preg_replace("[^A-Za-z0-9]", "", $_POST['companys_name']); // filter everything but numbers and letters
$admin_first_name = preg_replace("[^A-Za-z]", "", $_POST['admin_first_name']); // filter everything but letters
$admin_phone = preg_replace("[^0-9]", "", $_POST['admin_phone']);// Filters everything except numbers
$admin_email = preg_replace("[^A-Z a-z0-9]", "", $_POST['admin_email']); // filter everything but spaces, numbers, and letters

$admin_last_name = preg_replace("[^A-Z a-z]", "", $_POST['admin_last_name']); // filter everything but spaces, numbers, and letters
$admin_email = stripslashes($_POST['admin_email']);
$admin_email = strip_tags($admin_email);
$admin_email = mysql_real_escape_string($admin_email);
$admin_password = preg_replace("[^A-Za-z0-9]", "", $_POST['admin_password']); // filter everything but numbers and letters
// Check to see if the user filled all fields with
// the "Required"(*) symbol next to them in the join form
// and print out to them what they have forgotten to put in
if((!$companys_name) || (!$admin_first_name) || (!$admin_phone) || (!$admin_last_name) || (!$admin_email) || (!$admin_password)){
$errorMsg = "You did not submit the following required information!<br /><br />";
if(!$companys_name){

} else {

// Add user info into the database table, claim your fields then values
$sql = mysql_query("INSERT INTO toc_companys (companys_name, admin_first_name, admin_phone, admin_url, admin_last_name, admin_email, admin_password )

exit(); // Exit so the form and page does not display, just this success message

我的老师希望我这样做，当有人点击注册时，会弹出一个JavaScript框，要求用户重新输入他们的密码，这样它就可以检查输入框，如果它们是相同的，它会创建他们的帐户如果不是它不会离开页面但它会告诉他们他们的密码不一样。

通过JQuery伪代码：
$('#submit').click(function(){
$('#box').show();
});
$('#box > #confirm').click(function(){
var firstInput = $('#firstInput').val();
var secondInput = $('#secondInput').val();
if(!firstInput.equal(secondInput)) {
//do something if they are not the same
}
});

为您的表单设置ID，然后添加一个框：
<form id="myform" action="join.php" method="get" >
...
</form>
<div id="box" style="display: none; width: 100px; height: 100px; backgournd-color: #FFFFFF;">
<input id="confirmPassword"/>
<span id="info"></span>
<button id="confirm">confirm</button>
</div
在.html
的底部添加脚本$('#myform').submit(function(){
$('#box').show();
return false; // cancel the submit action
});
$('confirm').click(function(){
if($('input[value="admin_password"]').val().equal($('#confirmPassword').val())) {
$('#myform').submit(); // to submit the form here
} else {
$('#info').text("passwords are not the same!").show().fadeOut(1000);
}
});
