用vue2.x註冊一個全局的彈窗alert組件、confirm組件

1、在實際的開發當中,彈窗是少不了的,默認系統的彈窗樣式太醜,難以知足項目的實際需求,因此須要本身定義彈窗組件,把彈窗組價定義爲全局的,這樣減小每次使用的時候引入麻煩,節省開發時間。本文將分享如何定義一個全局的彈窗組件。下邊開始上代碼。css

2、實際代碼以下:vue

1.在components目錄下的public目錄新建一個文件夾alert,而後新建兩個文件alert.vue和alert.scss。組件的樣式代碼我喜歡跟組件放到一塊兒,這樣按模塊去劃分管理。公共的樣式就放到公共的樣式文件裏就好了。web

2.alert.vue代碼以下sass

<template>
  <div class="alertModal" ref="alert">
    <!--social post彈框-->
      <transition name="fade">
          <div v-if="modelFlag==1" class="alertbox">
            <div class="alert-dialog">
              <div class="alert-content">
                <div class="alert-header">
                    <span  class="alertclose" @click="close">×</span>
                    <span class="alert-title">
                       {{modelTitle}}
                    </span>
                </div>
                <div class="alert-body">
                    {{modelContent}}
                </div>
                <div class="alert-footer">
                    <button class="alertbtn"  @click="close">{{modelClose}}</button>
                    <button class="alertbtn alert-info" @click="submit">{{modelSave}}</button>
                </div>
              </div>
            </div>
        </div>
      </transition>
      <div v-if="modelFlag==1" class="modal-backdrop"></div>
  </div>
</template>

<script>

export default {
    data(){
        return{
            modelFlag:0,//0爲消失,1爲顯示
            modelTitle:'Alert',//彈窗標題
            modelClose:'取消',//取消按鈕文字
            modelContent:'',//彈窗內容
            modelSave:'肯定',//肯定按鈕文字
            callBack:null,//是否須要回調函數
        }
    },
    methods:{
        //回調函數
        doCallBack(){
            if(typeof this.callBack == 'function'){
                this.callBack()
                this.callBack=null;
            }
        },
        //關閉彈窗,數據重置
        close(){
           this.modelFlag=0;
           this.modelTitle='Alert';
           this.modelClose='取消';
           this.modelContent='';
           this.modelSave='肯定';
           this.callBack=null;
        },
        //點擊肯定按鈕彈窗消失
        submit(){
this.doCallBack()
this.close() }, //顯示彈窗,記性複製 show(options){ if(this.modelFlag==1){return}; this.modelTitle=options.modelTitle||this.modelTitle; this.modelContent=options.modelContent; this.modelFlag=1; this.modelSave=options.modelSave||this.modelSave; this.modelClose=options.modelClose||this.modelClose; if(options.callBack){ this.callBack=options.callBack; } }, }, watch:{ } } </script> <!-- Add "scoped" attribute to limit CSS to this component only --> <style lang="sass" scoped> @import 'alert.scss' </style>

3.在App.vue中引入組件並註冊,函數

import alert from 'components/public/alert/alert.vue'
mounted(){
        Vue.prototype.$alert=this.$refs.alert;
    },
  components:{
      alert
  }
<alert ref='alert'></alert>

在外層div下加上組件。post

4.使用彈窗this

好比我在一個頁面那裏點擊一個button而後調用顯示這彈窗,則:spa

<button @click="showalert">show alert</button>
methods:{
        showalert(){
               this.$alert.show({modelTitle:"Alert Msg",
                          modelContent:'Please Check!'})
        }
    },

this.$alert.show({modelTitle:"Alert Msg",modelContent:'Please Check!'}),show方法裏邊傳一個對象,裏邊是相應的配置。prototype

這樣就能夠使用啦!code

5.使用confirm功能,在對象里加入callBack回調函數:

showalert(){
               this.$alert.show({modelTitle:"Alert Msg",modelContent:'你肯定刪除嗎?',callBack:()=>{
                   alert(1)
               }})
        }

結果以下:

 

6.最後附上樣式代碼

.modal.fade .alert-dialog {
  -webkit-transition: -webkit-transform .3s ease-out;
       -o-transition:      -o-transform .3s ease-out;
          transition:         transform .3s ease-out;
  -webkit-transform: translate(0, -25%);
      -ms-transform: translate(0, -25%);
       -o-transform: translate(0, -25%);
          transform: translate(0, -25%);
}

}


.fade-enter-active, .fade-leave-active {

    bottom: 0;

    z-index: 1040;
    background-color: #000;
    opacity: 0.5;
}

.el-icon-date{
    cursor: pointer;
}
.alert-header{
    
}
.alert-title{
    font-size: 18px;
    line-height: 1;
    color: #2d2f33;
}
.alert-body{
    padding: 10px 0px;
    color: #5a5e66;
    font-size: 14px;
    line-height: 17px;
}
.alertbtn{
    text-align: center;
    font-weight: 500;
    cursor: pointer;
    padding: 9px 15px;
    font-size: 12px;
    border-radius: 3px;
    line-height: 1;
    background: #fff;
    border: 1px solid #d8dce5;
    border-color: #d8dce5;
    color: #5a5e66;
}
.alert-info{
    color: #fff;
    background-color: #409eff;
    border-color: #409eff;
}
.alertclose{
    float: right;
    cursor: pointer;
}
