vue data里面存儲數據

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <title>www.49028c.com vue data里面存儲數據</title>  <style>  </style>  <script src="https://cdn.bootcss.com/vue/2.4.4/vue.min.js"></script>  <script>    window.onload=function(){      new Vue({        el:'body',        data:{          msg:'welcome vue',          msg2:12,          msg3:true,          arr:['apple','banana','orange','pear'],          json:{a:'apple',b:'banana',c:'orange'}        }      });    };  </script></head><body>  <input type="text" v-model="msg">  <input type="text" v-model="msg">  <br>  {{msg}}  <br>  {{msg2}}  <br>  {{msg3}}  <br>  {{arr}}  <br>  {{json}}</body></html>

vue v-for循環

v-for循環:

v-for="name in arr"
{{value}} {{$index}}

v-for="name in json"
{{value}} {{index}} {{index}} {{key}}

v-for="(k,v) in json"
{{k}} {{v}} {{index}} {{index}} {{key}}
