Question

这是我的register.jsp页面。这是我使用javascript验证表单的地方

  <script>
        function validateForm()
        {

            var x = document.forms["myForm"]["firstname"].value;
            if (x === null || x === "")
            {
                alert("First name must be filled out");
                return false;
            }

            var x = document.forms["myForm"]["lastname"].value;
            if (x === null || x === "")
            {
                alert("Second name must be filled out");
                return false;
            }

            var x = document.forms["myForm"]["username"].value;
            if (x === null || x === "")
            {
                alert("User name must be filled out");
                return false;
            }

            var x = document.forms["myForm"]["password"].value;
            if (x === null || x === "")
            {
                alert("Password must be filled out");
                return false;
            }


            var x = document.forms["myForm"]["username"].value;
            for (var i = 0; i < username.length; i++) {

                if (username[i] === newName)

                {

                    alert("USER");

                    success = false;

                    //stop further program execution

                    return false;

                }
            }
        }

    </script>

以下是用户填写的表单。

在此注册：

            <form class="form" name="myForm" id="loginForm" action="regServlet" method="doPost" onsubmit="return validateForm();" >

                <input id="name" name="firstname"  placeholder="Firstname" class="element text medium" type="text" maxlength="255" value=""/> 


                <br>

                <p class="contact">

                <input id="element_4" name="password" placeholder="Password" class="element text medium" type="password" maxlength="255" value=""/> 



                <br>
                <p class="contact">

                <p> Press To Submit </p>


                <input id="loginButton" class="uname" type="hidden" name="action" value="register" />
                <input type="submit" value="register" />
                </ul>
            </form>

我希望能够弹出一个说明用户已成功注册的内容。我该怎么做呢？

Answer 1

在servlet中，您可以设置一个请求属性，然后转发回register.jsp页面，在那里您可以恢复它并显示弹出窗口

用户注册成功后弹出消息
