推荐答案

做这样的事情并像这样传递你的值，你可以检查你的 profile.php 页面......在这里你不能检查 if(isset($_POST['submit']))，但是你可以检查if(isset($_POST['name']))

Do something like this and pass your values like this and you can check in your profile.php page....Here you cannot check if(isset($_POST['submit'])), but you you can check if(isset($_POST['name']))

    <form method="post" name="form" enctype="multipart/form-data">
    <input type="text" name="name" id="name" placeholder="Name" required/>
    <input type="email" name="email" id="email" placeholder="Email" required/>
    <input type="password" name="pass" id="pass" placeholder="Password" required/>
    <input type="submit" name="submit" value="Send" onclick="myFunction()"/>
    </form>
    
  <script>
    function myFunction() {
    var name = document.getElementById("name").value;
    var email = document.getElementById("email").value;
    var password = document.getElementById("password").value;
    $.ajax({
            type : "POST",  //type of method
            url  : "profile.php",  //your page
            data : { name : name, email : email, password : password },// passing the values
            success: function(res){  
                                    //do what you want here...
                    }
        });
    }
    </script>
