Vue 提示框组件

OK，首先看看效果：

一、子组件（alert.vue）

<template>
  <transition name="alert">
    <div class="alert-all">
      <div class="alert-wraper determine">
        <p class="close-alert">
          <!-- <i class="fa fa-times" aria-hidden="true" title="关闭" @click="close()"></i> -->
        </p>
        <p :class="[{fail: ifFail}, 'title']">{{title}}</p>
        <div class="btn_wrapper">
          <!--<div class="cancel" @click="ok(false)">取消</div>-->
          <div class="ok" @click="ok(true)">确定</div>
        </div>
      </div>
    </div>
  </transition>
</template>
<script>
  export default {
    name: 'alert',
    props: {
      title: {
        type: String,
        default () {
          return {}
        }
      },
      type: {
        type: String,
        default () {
          return {}
        }
      },
      autoHide: {
        type: Boolean,
        default () {
          return true
        }
      }
    },
    data () {
      return {
        ifFail: ''
      }
    },
    methods: {
      ok: function (flag) {
        let data = {
          show: flag,
          type: this.type
        }
        this.$emit('okAlert', data)
      }
    },
    mounted () {
      if (this.type === 'fail') {
        this.ifFail = true
      } else {
        this.ifFail = false
      }
    }
  }
</script>
<style lang="less" scoped>
  .alert-all{
    position:fixed;
    100%;
    height:100%;
    top:0;
    left:0;
    z-index:9;
    .alert-wraper{
      400px;
      height:160px;
      background:#fff;
      position:absolute;
      top:0;
      left:0;
      right:0;
      bottom:0;
      margin:auto;
      box-shadow:0px 0px 20px #ddd;
      .close-alert{
        height:30px;
        height:30px;
        100%;
        background:#4499ee;
        position:relative;
        z-index:9;
        i{
          position:absolute;
          right:0;
          30px;
          height:30px;
          font-size: 20px;
          cursor:pointer;
          color:#fff;
        }
        i::before{
          position:absolute;
          left:6px;
          top:4px;
        }
        i:hover{
          background:#6db2f8;
        }
      }
      .fail{
        color:red;
      }
      .title{
        box-sizing: border-box;
        padding: 0 10px;
        100%;
        height:130px;
        line-height: 25px;
        font-size:14px;
        font-weight: normal;
        text-align:center;
        display: flex;
        justify-content: center;
        align-items: center;
      }
    }
    .determine{
      height: 220px;
    }
    .btn_wrapper{
      text-align: center;
    }
    .cancel, .ok{
      display: inline-block;
       80px;
      height: 30px;
      border-radius: 20px;
      border: 1px solid #4499ee;
      text-align: center;
      line-height: 30px;
      color: #4499ee;
      margin:0 20px;
    }
    .cancel:hover, .ok:hover{
      cursor: pointer;
      box-shadow: 0 0 4px #4499ee;
    }
  }
  .alert-enter-active,.alert-leave-active{
    transition: all .4s
  }
  .alert-enter, .alert-leave-to{
    opacity: 0;
    transform: translateY(-60px);
  }
</style>

二、父组件中引用子组件（alert.vue）

<template>
  <div class="container">
      <alerter 
      v-if="alertManager.show" 
      :type="alertManager.type"
      :title="alertManager.title">
    </alerter>
  </div>
</template>

三、父组件中定义变量

export default {
  data () {
    return {
     alertManager: {
        show: false,
        type: '',
        title: ''
      }    
    }
}

四、父组件中写弹出框方法

 methods: {
    alert (show, type, title, autoHide) {
      this.alertManager = {
        show: show,
        type: type,
        title: title
      }
      if (autoHide === true) {
        let that = this
        setTimeout(function () {
          that.alertManager.show = false
        }, 2000)
      }
    }
}

五、调用方法

that.alert(true, 'success', '提交成功', true)
