vue.js搭建用户管理系统练手（五）----嵌入弹窗组件

当我们添加用户成功后，希望能弹出一个窗口信息告诉用户添加成功。

首先在components中新建Alert.vue:

<template>
<div class="alert alert-warning alert-dismissible" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
   {{message}}
</div>
</template>

<script>
export default {
  name: 'alert',
  props:["message"],
  data () {
    return {

    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>

这里是通过props的message来进行组件的通信的！

然后在Customers.vue中引用这个Alert.vue组件：

<template>
  <div class="customers container">
  <Alert v-if="alert" v-bind:message="alert"></Alert>
  <h1 class="page-header">用户管理系统</h1>
  <table class="table table-striped">
    <thead>
        <tr>
            <th>姓名</th>
            <th>电话</th>
            <th>邮箱</th>
            <th></th>
        </tr>
    </thead>
     <tbody>
        <tr v-for="customer in customers">
            <td>{{customer.name}}</td>
            <td>{{customer.phone}}</td>
            <td>{{customer.email}}</td>
            <td></td>
        </tr>
     </tbody>
  </table>

  </div>
</template>

<script>
import Alert from "./Alert"
export default { 
  name: 'customers',
  data () {
    return {
        customers:[],
        alert:""
    }
  },
  methods:{
    fetchCustomers(){
        this.$http.get("http://localhost:3000/users")
            .then(function(response){
               //console.log(response);
               this.customers = response.body;
            })
    }
  },
    created(){
        if(this.$route.query.alert){
            this.alert = this.$route.query.alert;//将获得的message赋值给alert，再通过v-bind:message="alert"进行父子组件信息的传递
        }
        this.fetchCustomers();
    },
    updated(){
        this.fetchCustomers();
    },
  components:{
    Alert
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>

最后在添加用户成功后去传递窗口要弹出的信息message:

<template>
  <div class="add container">
    <h1 class="page-header">添加用户</h1>
    <form v-on:submit="addCustomer">
        <div class="well">
            <h4>用户信息</h4>
            <div class="form-group">
                <label>姓名</label>
                <input type="text" class="form-control" placeholder="name" v-model="customer.name">
            </div>
            <div class="form-group">
                <label>电话</label>
                <input type="text" class="form-control" placeholder="phone" v-model="customer.phone">
            </div>
            <div class="form-group">
                <label>邮箱</label>
                <input type="text" class="form-control" placeholder="email" v-model="customer.email">
            </div>
            <div class="form-group">
                <label>学历</label>
                <input type="text" class="form-control" placeholder="education" v-model="customer.education">
            </div>
            <div class="form-group">
                <label>毕业学校</label>
                <input type="text" class="form-control" placeholder="graduationschool" v-model="customer.graduationschool">
            </div>
            <div class="form-group">
                <label>职业</label>
                <input type="text" class="form-control" placeholder="profession" v-model="customer.profession">
            </div>
            <div class="form-group">
                <label>个人简介</label>
                <!-- <input type="text" class="form-control" placeholder="profile" v-model="customer.profile"> -->
                <textarea class="form-control" rows="10" v-model="customer.profile"></textarea>
            </div>
            <button type="submit" class="btn btn-primary">添加</button>
        </div>
    </form>
  </div>
</template>

<script>
export default {
  name: 'add',
  data () {
    return {
      customer:{}
    }
  },
  methods:{
    addCustomer(e){
        // console.log(123);
        if (!this.customer.name || !this.customer.phone || !this.customer.email) {
             console.log("请添加对应的信息!");
        }else{
            let newCustomer = {
                name:this.customer.name,
                phone:this.customer.phone,
                email:this.customer.email,
                education:this.customer.education,
                graduationschool:this.customer.graduationschool,
                profession:this.customer.profession,
                profile:this.customer.profile
            }

            this.$http.post("http://localhost:3000/users",newCustomer)
                .then(function(response){
                    // console.log(response);
                    this.$router.push({path:"/",query:{alert:"用户信息添加成功"}});
                })
            e.preventDefault();
        }
        e.preventDefault();
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>

就是修改了this.$router.push({path:"/",query:{alert:"用户信息添加成功"}});
这一行代码！
