使用v-bind绑定class,实现动态的样式切换

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>绑定样式</title>
        <script src="vue.js"></script>
    </head>
    <body>

        <div id="app">
            <div v-bind:class="yellow"></div>
            <div v-bind:class="[yellow,red]"></div>
            <div v-bind:class="{yellow:status}"></div>
        </div>

        <style>
            
            .yellow {
                width: 200px;
                height: 200px;
                background: #ff0;
            }
            
            .red {
                width: 200px;
                height: 200px;
                background: red;
            }
            
        </style>

        <script>
            var vm = new Vue({

                el: '#app',
                data: {
                    yellow : 'yellow',
                    red    : 'red',
                    status : true
                }
            })
        </script>

    </body>
</html>
