Vue.js 有没有办法在 VueJS 中使用 mixins 继承模板

发布于10月30日

有人知道如何用模板继承mixin吗？或者如何从mixin中注入微量元素或组件？

EDIT:

谢谢

mixin = {
  template: '<p>{{ foo }}</p>',
  data() {
    return {
      foo: 'Hello',
    };
  },
}

// This should  be <div><p>Hello</p><p>World!</p></div>
Vue.component('greeting', {
  mixins: [mixin],
  template: '<div><p>World!</p></div>'
});

var vm = new Vue({
  el: '#app'
});

<script src="https://cdn.jsdelivr.net/vue/1.0.16/vue.js"></script>
<div id="app">
  <greeting></greeting>
</div>

多年后，我可以想象一个优雅的解决方案，也许使用类、typescript或在mixin中创建组件super的注释会更优雅，但现在，问题已经部分解决了.

GreetingMixin = {
  data() {
    return {
      greeting: 'Hello',
    };
  },
  provide() { return {child: this}},
  components: {
    super: {
      inject: ['child'],
      template: '<div class="blue">{{ child.greeting }} <strong><slot /></strong></div>',
    }
  },
}


// This should be <div class="blue">Hello <strong>World!</strong></div>
Vue.component('welcomeWorld', {
  mixins: [GreetingMixin],
  template: '<super>World!</super>',
});

// This should be <div class="blue">Hi <strong><i>ali</i></strong></div>
Vue.component('welcomeName', {
  mixins: [GreetingMixin],
  props: ["name"],
  created() { this.greeting = "Hi" },
  template: '<super><i>{{ name }}</i></super>',
});

// This should be <h1><div class="blue">Hello <strong>World</strong></div></h1>
Vue.component('welcomeH1', {
  mixins: [GreetingMixin],
  props: ["name"],
  template: '<h1><super>{{ name }}</super></h1>',
});


var vm = new Vue({
  el: '#app'
});

.blue {
color: blue
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
  <welcome-world></welcome-world>
  <welcome-name name="Ali"></welcome-name>
  <welcome-h1 name="Ali"></welcome-h1>
</div>
