Vue 中可以定义组件模版的几种方式

Vue.component("my-button", {
 data: function () {
 return {
  label: "是兄弟就来砍我"
 }
 },
 template: "<button>{{label}}</button>"
});

Vue.component("my-content", {
 data: function () {
 return {
  label: "是兄弟就来砍我",
  content: "刀刀暴击"
 }
 },
 template: `
 <div>
  <button>{{ label }}</button>
  <span>{{ content }}</span>
 </div>
 `
});

<my-label inline-template>
 <span>{{label}}</span>
</my-label>
Vue.component('my-label', {
 data: function () {
 return {
  label: "赶紧上车吧，兄die"
 }
 }
})

<script type="text/x-template" id="label-template">
 <span>{{label}}</span>
</script>
Vue.component('my-label', {
 template: "#label-template",
 data: function () {
 return {
  label: "赶紧上车吧，兄die"
 }
 }
})

Vue.component('my-label', {
 data: function () {
 return {
  items: ['来就送！', '来就送！', '来就送！']
 }
 },
 render: function (createElement) {
 if (this.items.length) {
  return createElement('ul', this.items.map(function (item) {
  return createElement('li', item)
  }))
 } else {
  return createElement('p', '活动结束')
 }
 }
})

Vue.component('my-label', {
 data: function () {
 return {
  label: ["活动结束"]
 }
 },
 render(){
 return <div>{this.label}</div>
 }
})

<template>
 <div>
 <ul>
  <li v-for="(item, index) in items" :key="index">{{item}}</li>
 </ul>
 </div>
</template>
<script>
export default {
 data() {
 return {
  items: ["我砍", "我砍", "我砍"]
 };
 }
};
</script>
