一个简单的登录页面_第1张图片

jsp代码
==>body部分,底部有js代码,使用的是vue.js的方法

<body>
    <div id="app">
        <form class="box" action="/login/do_login" method="post">
            <h1>login</h1>
            <input type="text" v-model="username" placeholder="Enter the Username">
            <input type="password" v-model="password" placeholder="Enter the Password">
            <input type="text" v-model="code" placeholder="Enter the code">
            <div>
                <img id="randomCode" alt="验证码" src="/random_code" onclick="changeImg()" style="cursor: pointer;">
            </div>
            <input type="submit" @click="login" value="Login">
            <input type="reset" @click="login" value="Reset">
        </form>
    </div>

    <script type="text/javascript" src="${pageContext.request.contextPath}/static/login/js/jquery.min.js"></script>
    <script type="text/javascript" src="${pageContext.request.contextPath}/static/login/js/vue/vue.min.js"></script>

    <script type="text/javascript">
        function changeImg() {
            // 拿到当前图片元素
            let randomCode = document.getElementById("randomCode");
            // 修改这张图片的src路径
            // 加上时间戳,因为如果访问路径和之前一样的话,浏览器为认为我们访问了相同的资源,就不会再刷新修改验证码图片
            randomCode.src = "/random_code?date=" + new Date();
        }

        let app = new Vue({
            el: "#app",
            data: {
                username: "",
                password: "",
                info: "",
                code: ""
            },
            methods: {
                login() {
                    let _this = this;
                    $.post("/login/do_login", {
                        username: this.username,
                        password: this.password,
                        code: this.code
                    }, function (data) {
                        if (data.success) {
                            location.replace("/admin/index");
                        } else {
                            if (data.msg) {
                                _this.info = "" + data.msg + "";
                            } else {
                                _this.info = "未知错误"
                            }
                        }
                    });
                },
                reset() {
                    this.username = "";
                    this.password = "";
                    this.code = "";
                }
            }
        })
    </script>
</body>

样式部分style.css
==>因为引入style.css失败,原因目前还没找到,就暂时写在页面style标签中了

<style type="text/css">
        body{//清除样式,设置字体和背景
            margin: 0;
            padding: 0;

总结:一个简单登录页面,主要是样式设置,js用的是vue.js,主要是加强css认识
