import Vue from 'vue'
import TodoList from './TodoList'

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  components: { TodoList },
  template: '<TodoList/>'
})

TodoList.vue

<template>
  <div id="app">
    <!--<img src="./assets/logo.png">
    <HelloWorld/>-->
    <input v-model="inputValue" />
    <button @click="handleSubmit">提交</button>
    <ul>
      <todo-item 
        v-for="(item,index) of list"
        :key="index"
        :content="item"
        :index="index"
        @delete="handleDelete"
      ></todo-item>
    </ul>
  </div>
</template>

<script>
// import HelloWorld from './components/HelloWorld'
import TodoItem from './components/TodoItem'
export default {
  // name: 'App',
  components: {
    TodoItem
  },
  data(){
    return{
      inputValue : '',
      list : [],
    }
  },
  methods: {
    handleSubmit(){
      this.list.push(this.inputValue);
      this.inputValue = '';
    },
    handleDelete(index){
      this.list.splice(index,1);
    }
  }
}
</script>

<style>
/*#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}*/
</style>

TodoItem.vue

<template>
  <li class="item" v-on:click="handleDelete">{{content}}</li>
</template>

<script>
export default {
  name: 'HelloWorld',
  props: ['content','index'],
  data () {
    return {

    }
  },
  methods: {
    handleDelete(){
      this.$emit('delete',this.index);
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.item{
  color: green;
}
</style>
