一 vue方法实现

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Vue方法与事件</title>
        <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
        <script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
    </head>
    <body>
        <div id="test">
            <button @click="sayHi">点击我</button> <!--这里使用@-->
        </div>
        <script type="text/javascript">
            var myVue = new Vue({
                el: '#test',
                methods: {      //这里使用methods
                    sayHi: function () {
                        alert('我被点击了')
                    }
                }
            })
        </script>
    </body>
</html>

 

二 方法传参

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Vue方法与事件</title>
        <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
        <script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
    </head>
    <body>
        <div id="test">
            <button @click="sayHi('你好')">说你好</button> <!--这里使用@-->
            <button @click="sayHi('我被点击了')">说我被点击了</button> <!--这里使用@-->
        </div>
        <script type="text/javascript">
            var myVue = new Vue({
                el: '#test',
                methods: {      //这里使用methods
                    sayHi: function (message) {
                        alert(message)
                    }
                }
            })
        </script>
    </body>
</html>

 

三 vue访问原生 DOM 事件

注意用$event获取

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Vue方法与事件</title>
        <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
        <script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
    </head>
    <body>
        <div id="test">
            <button @click="changeColor('你好',$event)">点击我</button> <!--这里使用@-->
            <div style="height: 100px;width: 100px;background-color: red;" @mouseover="over('鼠标从我上面滑过',$event)">
                鼠标从我上面滑过试试
            </div>
        </div>
        <script type="text/javascript">
            var myVue = new Vue({
                el: '#test',
                methods: {      //这里使用methods
                    changeColor: function (message, event) {
                        alert(message+event);    //弹出我被点击了,事件是[object MouseEvent]
                    },
                    over :function (message, event) {
                        alert(message+event);   //弹出鼠标从我上面滑过,事件是[object MouseEvent]
                    }
                }
            })
        </script>
    </body>
</html>

 

四 事件修饰符

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Vue方法与事件</title>
        <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
        <script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
    </head>
    <body>
        <div id="test">
            <button @click.stop="sayHi('你好')">说你好</button> <!-- 阻止单击事件冒泡 -->
            <button @click.prevent="sayHi('你好')">说你好</button> <!-- 提交事件不再重载页面 -->
            <button @click.stop.prevent="sayHi('你好')">说你好</button> <!-- 阻止单击事件冒泡和提交事件不再重载页面 -->
            <button @click.capture="sayHi('你好')">说你好</button>  <!-- 添加事件侦听器时使用 capture 模式 -->
            <button @click.self="sayHi('你好')">说你好</button>    <!-- 只当事件在该元素本身（而不是子元素）触发时触发回调 -->
            
            <div @keyup.13="sayHi('你好')">说你好</div>  <!-- 只有在 keyCode 是 13 时调用 vm.submit() -->
        </div>
        <script type="text/javascript">
            var myVue = new Vue({
                el: '#test',
                methods: {      //这里使用methods
                    sayHi: function (message) {
                        alert(message)
                    }
                }
            })
        </script>
    </body>
</html>
