Question

我希望在ajax函数完成后调用另一个函数。成功注册用户后，我想要一个回调函数，但是当我尝试时，我的注册功能停止工作：

<?php
include('connection.php');
$firstname = "";
$lastname = "";
$email = "";
$contact = "";
$message = "";
$sql = "";
$table = "comments";
if (isset($_REQUEST['firstname']) && isset($_REQUEST['lastname']) &&    isset($_REQUEST['email']) && isset($_REQUEST['contact']) && isset($_REQUEST['message'])) {
//echo "Hi";
$firstname = "'" . $_REQUEST['firstname'] . "'";
$lastname = "'" . $_REQUEST['lastname'] . "'";
$email = "'" . $_REQUEST['email'] . "'";
$contact = $_REQUEST['contact'];
$message = "'" . $_REQUEST['message'] . "'";
$sql = "INSERT INTO {$table} VALUES (NULL,{$firstname},{$lastname},{$email},{$contact},{$message})";
if (mysqli_query($conn, $sql)) {


    echo "<div class='alert alert-success' ><h4>Your message has successfully been sent.</h4></div>

        <div class=\"text-right\">
                    <button class=\"btn btn-danger\" data-dismiss=\"modal\">Close</button>

        </div>";
} else {
    echo "<div class='alert alert-danger' ><h4> Message sending failed.</h4></div>

        <div class=\"text-right\">
                    <button class=\"btn btn-danger\" data-dismiss=\"modal\">Close</button>

        </div>";
}
} else {
echo "<div class='alert alert-danger' ><h4>Message sending failed.</h4></div>

        <div class=\"text-right\">
                    <button class=\"btn btn-danger\" data-dismiss=\"modal\">Close</button>

        </div>";
}

编辑你的$(document).ready(function()..不应该在另一个函数中，因为这样只会在调用该函数时调用它，并且可能不是你想要的那样，因为我不知道你如何使用signUp（）函数，我无法真正说出来。

您可以使用这种方式制作ajax请求

function signUp(){
$(document).ready(function() {
    $("#register").click(function() {
        var name = $("#name").val();
        var email = $("#email").val();
        var password = $("#password").val();
        var cpassword = $("#cpassword").val();

        if (name == '' || email == '' || password == '' || cpassword == '') {
            alert("Please fill all fields...!!!!!!");
        } else if ((password.length) < 8) {
            alert("Password should atleast 8 character in length...!!!!!!");
        } else if (!(password).match(cpassword)) {
            alert("Your passwords don't match. Try again?");
        } else {
            $.ajax({
                    type: "POST", 
                    url: "http://localhost:5000/your/endpoint",
                    data: {
                        name1: name,
                        email1: email,
                        password1: password
                    },
                    success: function (data, status, xhr) {
                        // function called when it has succeeded 
                        // Do what you want here in case of success
                        // The best way to do this should be used with statusCode because basically you
                        // only want to know that your post was OK.

                    },
                    statusCode: {
                        // Add more status code if you want to do something for each
                        200: function(){
                             $("form")[0].reset();
                             alert('You have Successfully Registered.....');
                        },
                        500: function(){
                            // In case of server error you should do something also
                        }
                    }
                    error: function(xhr, msg, err){
                        // Function called when error happens
                    }
            })

        }
    });
});

}

您甚至可以定义在给定状态代码作为响应时调用的函数，您可以在http://api.jquery.com/jquery.ajax/上找到完整的参考
