<script type = "text/javascript" src = "js/js_functions.js"> </script>  
<form method="post" onsubmit = "return testAjax();" />
    <input   type="email" placeholder="email" name="email" required maxlength = "50"><br>

signup.html:

<script type = "text/javascript" src="js/js_functions.js"></script>
<form method="post" onsubmit="return ajaxTest();"/>
            <input   type="text" placeholder="username" name="username"     required = "required" maxlength = "15"><br>
            <input  type="password" placeholder="password" name="password" required = "required" pattern = "(?=.*\d)(?=.*[A-Z]).{10,}"><br>
            <input  type="password" placeholder="re-enter password"name="repassword" required = "required"><br>
            <p class = "passwordreq">Password must:</p>

            <input type="submit" value="sign up"> <input type="button" value="go back"  onclick="window.location='index.html'">
        </form>

js_函数

var username, password;
function setUsrandPass(form)
{
if(form.password.value != form.repassword.value)
{
    alert("Passwords do not match");

}

else {
    username = form.username.value;
    password = form.password.value; 

    window.location = 'verifyemail.html';

}

return false; 
}

function ajaxTest()
{
if(form.email.value != form.reemail.value)
{
    alert("Emails do not match");

}

else
$.ajax({
    type: 'GET',
    url: 'signup_script.php',
    data: {usr: username, pass: password, em: form.email.value},
});

return false; 
}

PHP 脚本:

<?php 

include 'profile_Functions.php';

$username = $_GET['usr'];
$password = $_GET['pass'];
$email = $_GET['em'];

echo "got here!";

createUser($username,$password,$email);
?>

对于来自不同页面的内容来说这是不可能的。他们需要向 PHP 脚本发出相同的请求来提供这两种数据。

您可以通过使用 PHP 写入某种数据存储(即文件或数据库)来规避此问题，然后等待其他脚本也写入，然后 PHP 可以进行所需的任何处理。
