What are the several ways for vue to create components

1. Use Vue.extend to create global Vue components

<div id="app">
    <!-- 如果要使用组件,直接,把组件的名称,以 HTML 标签的形式,引入到页面中,即可 -->
    <mycom1></mycom1>
  </div>
  <script>
    // 1.1 使用 Vue.extend 来创建全局的Vue组件
    // var com1 = Vue.extend({
    //   template: &#39;<h3 id="这是使用-nbsp-Vue-extend-nbsp-创建的组件">这是使用 Vue.extend 创建的组件</h3>&#39; // 通过 template 属性,指定了组件要展示的HTML结构
    // })
    // 1.2 使用 Vue.component(&#39;组件的名称&#39;, 创建出来的组件模板对象)
    // Vue.component(&#39;myCom1&#39;, com1)
    // 如果使用 Vue.component 定义全局组件的时候,组件名称使用了 驼峰命名,则在引用组件的时候,需要把 大写的驼峰改为小写的字母,同时,两个单词之前,使用 - 链接;
    // 如果不使用驼峰,则直接拿名称来使用即可;
    // Vue.component(&#39;mycom1&#39;, com1)
    // Vue.component 第一个参数:组件的名称,将来在引用组件的时候,就是一个 标签形式 来引入 它的
    // 第二个参数: Vue.extend 创建的组件  ,其中 template 就是组件将来要展示的HTML内容
    Vue.component(&#39;mycom1&#39;, Vue.extend({
      template: &#39;<h3 id="这是使用-nbsp-Vue-extend-nbsp-创建的组件">这是使用 Vue.extend 创建的组件</h3>&#39;
    }))
    // 创建 Vue 实例,得到 ViewModel
    var vm = new Vue({
      el: &#39;#app&#39;,
      data: {},
      methods: {}
    });
  </script>

2. Use Vue.component to create directly

  <div id="app">
    <!-- 还是使用 标签形式,引入自己的组件 -->
    <mycom2></mycom2>
  </div>
  <script>
    // 注意:不论是哪种方式创建出来的组件,组件的 template 属性指向的模板内容,必须有且只能有唯一的一个根元素
    Vue.component(&#39;mycom2&#39;, {
      template: &#39;<div><h3 id="这是直接使用-nbsp-Vue-component-nbsp-创建出来的组件">这是直接使用 Vue.component 创建出来的组件</h3><span>123</span></div>&#39;
    })
    // 创建 Vue 实例,得到 ViewModel
    var vm = new Vue({
      el: &#39;#app&#39;,
      data: {},
      methods: {}
    });
  </script>

3. Outside the controlled #app, use the template element to define the HTML template structure of the component

<div id="app">
    <mycom3></mycom3>
    <!-- <login></login> -->
  </div>
  <div id="app2">
    <mycom3></mycom3>
    <login></login>
  </div>
  <!-- 在被控制的 #app 外面,使用 template 元素,定义组件的HTML模板结构  -->
  <template id="tmpl">
    <div>
      <h1 id="这是通过-nbsp-template-nbsp-元素-在外部定义的组件结构-这个方式-有代码的只能提示和高亮">这是通过 template 元素,在外部定义的组件结构,这个方式,有代码的只能提示和高亮</h1>
      <h4 id="好用-不错">好用,不错!</h4>
    </div>
  </template>
  <template id="tmpl2">
    <h1 id="这是私有的-nbsp-login-nbsp-组件">这是私有的 login 组件</h1>
  </template>
  <script>
    Vue.component(&#39;mycom3&#39;, {
      template: &#39;#tmpl&#39;
    })
    // 创建 Vue 实例,得到 ViewModel
    var vm = new Vue({
      el: &#39;#app&#39;,
      data: {},
      methods: {}
    });
    var vm2 = new Vue({
      el: &#39;#app2&#39;,
      data: {},
      methods: {},
      filters: {},
      directives: {},
      components: { // 定义实例内部私有组件的
        login: {
          template: &#39;#tmpl2&#39;
        }
      },
    })
  </script>
