弹出框--模态框

创建Modal组件

<template>
    <div>
      <div class="md-modal modal-msg md-modal-transition" v-bind:class="{'md-show':mdShow}">
        <div class="md-modal-inner">
          <div class="md-top">
            <button class="md-close" @click="closeModal">Close</button>
          </div>
          <div class="md-content">
            <div class="confirm-tips">
              <slot name="message"></slot>
            </div>
            <div class="btn-wrap">
              <slot name="btnGroup"></slot>
            </div>
          </div>
        </div>
      </div>

      <div class="md-overlay" v-if="mdShow" @click="closeModal"></div>
    </div>
</template>
<script>
    export default{
        props:["mdShow"],
        data(){
            return{
                msg:'hello vue'
            }
        },
        methods:{
          closeModal(){
            this.$emit("close");
          }
        }
    }
</script>
<style scoped>
</style>

引入父组件中

<template>
  <div class="hello">
    <div>
      <button @click="addCart">点击弹出</button>
    </div>
    <Modal :mdShow="mdShow" @close="closeModal">
          <p slot="message">
             请先登录,否则无法加入到购物车中!
          </p>
          <div slot="btnGroup">
              <a class="btn btn-m" @click="closeModal">关闭</a>
              <!-- <a href="javascript:;" class="btn btn-m" @click="closeModal">继续购物</a>
              <router-link href="javascript:;" class="btn btn-m" to="/cart" >查看购物车</router-link> -->

          </div>
    </Modal>
  </div>
</template>

<script>
import Modal from "./Modal"
export default {
  name: 'HelloWorld',
  components:{
    Modal
  },
  data () {
    return {
      mdShow:false
    }
  },
  methods:{
    addCart(){
      this.mdShow=true
    },
    closeModal(){
      this.mdShow=false
    }
  },
  
}
</script>
