参考书籍《Vue.js快跑:构建触手可及的高性能Web应用》第1章 Vue.js基础-----1-5模板中的循环(v-for)

另外一个我经常使用的指令是v-for,这个指令通过遍历一个数组或者对象,将指令所在的元素循环输出到页面上。

<!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>模板中的循环</title>
</head>

<body>
  <div id="app">
    <ul>
      <li v-for="book in books">{{book}}</li>
    </ul> 
  </div>
  <script src="https://unpkg.com/vue"></script>
  <script>
    new Vue({
      el: "#app",
      data: {
        path: location.pathname,
        books:["《茶馆》", "《龙须沟》", "《四世同堂》", "《骆驼祥子》"]
      }
    })
  </script>
</body>

</html>

用来遍历对象:

<!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>模板中的循环</title>
</head>

<body>
  <div id="app">
    <ul>
      <li v-for="book in books">{{book.name}}的价格为:{{book.price}}元</li>
    </ul>
  </div>
  <script src="https://unpkg.com/vue"></script>
  <script>
    new Vue({
      el: "#app",
      data: {
        path: location.pathname,
        books: [
          { name: "《茶馆》", price: "10.20" },
          { name: "《龙须沟》", price: "10.00" }, 
          { name: "《四世同堂》", price: "5.25" }, 
          { name: "《骆驼祥子》", price: "3.5" }]
      }
    })
  </script>
</body>

</html>
