1.进入目录DEOM，新建文件 8.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="lib/vue-2.4.0.js"></script>
</head>
<body>
    <div id="app">
        <h1 :style="{color:'red', 'font-weight':200}">这是一个h1</h1>
    </div>

    <script>
        var vm = new Vue({
            el:'#app',
            data:{},
            methods:{}
        });
    </script>

</body>
</html>

3.进入目录DEOM，修改文件 8.html，换一种写法

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="lib/vue-2.4.0.js"></script>
</head>
<body>
    <div id="app">
        <h1 :style="styleObj1">这是一个h1</h1>
    </div>

    <script>
        var vm = new Vue({
            el:'#app',
            data:{
                styleObj1:{color:'red', 'font-weight':200}
            },
            methods:{}
        });
    </script>

</body>
</html>

4.进入目录DEOM，修改文件 8.html，再换一种写法

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="lib/vue-2.4.0.js"></script>
</head>
<body>
    <div id="app">
        <!-- 对象就是无序键值对的集合 -->
        <!-- <h1 :style="styleObj1">这是一个h1</h1> -->

        <h1 :style="[styleObj1, styleObj2]">这是一个h1</h1>
    </div>

    <script>
        var vm = new Vue({
            el:'#app',
            data:{
                styleObj1:{color:'red', 'font-weight':200},
                styleObj2:{'font-style':'italic'}
            },
            methods:{}
        });
