学学前端框架vue,之前学的太浅了,之前一小时写完后端,得用4个小时调试前端,太痛苦了

于是打算系统地从头开始学一学vue

今日代码

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>day01</title>
</head>

<body>
    <div id="app">
        <button @click="cnt++">+</button>
        <span>{{cnt}}</span>
        <button @click="cnt--">-</button>
        <button @click="fn()">log</button>
        <input type="text" v-model="username">
        <span>{{username}}</span>
        <li v-for="(item, index) in list" >{{item}}</li>
    </div>

    <script src="https://cdn.jsdelivr.net/npm/vue@2/dist/vue.js"></script>
    <script>

        const app = new Vue({
            el: '#app',
            data: {
                msg: 'hhhh',
                cnt: '123',
                list:['西瓜' , '急急急' , '看看'],
                username:'',
            },
            methods: {
                //methods中的this指向vue实例 
                //v-bind: 可以简写成:
                //v-for = "(item,index) in 数组"
               fn(){
                console.log('123');
               }
            },
            
        })
    </script>
</body>

</html>
