一篇文章带你深入浅出Vuex

作者:互联网

在写Vuex之前,我们先用一个简单的例子来实现一个小demo

大家都知道Vue的父传子用在很多场景,比如像这样:

父组件:

 <template>
  <div id="app">
    <product-list-one :msg='msg'></product-list-one>  
  </div>
  </template>
  <script>
  export default {
  name: 'app',
  components:{
    'product-list-one':ProductListOne,
  },
  data () {
    return {
      msg:'love'
    }
  }
}
</script>

 

子组件:

<template>
  <div id="product-list-one">
    <div>{{msg}}</div>
  </div>
</template>
<script>
props:['msg']
</script>

有父传子,当然也有子传父:

子组件:

<template>
  <div id="product-list-one">
    <button @click="but">点击</button>
  </div>
</template>
<script>
  data(){
    return {
      txt:'hello'
    }
  },
  methods:{
    but() {
      this.$emit('get',this.txt);
    }
  }
</script>

 

父组件:


<template>
  <div id="app">
    <product-list-one :msg='msg' @get='world'></product-list-one>  
  </div>
</template>
<script>
import ProductListOne from './components/ProductListOne.vue'
export default {
  name: 'app',
  components:{
    'product-list-one':ProductListOne
  },
  methods:{
    world(data){
      console.log(data)
    }
  }
}
</script>
