微信小程序封裝自定義彈窗的實現(xiàn)代碼

 更新時間:2019年05月08日 09:14:11   作者:Indus_wang  
這篇文章主要介紹了微信小程序封裝自定義彈窗的實現(xiàn)代碼,非常不錯,具有一定的參考借鑒價值,需要的朋友可以參考下

 最近在做小程序的登錄,需要同時獲取用戶手機號和頭像昵稱等信息,但是小程序又不支持單個接口同時獲取兩種數(shù)據(jù),因此想到自定義一個彈窗,通過彈窗按鈕觸發(fā)獲取手機號事件。記錄一下。

具體代碼如下:

業(yè)務(wù)代碼中:

  在業(yè)務(wù)代碼中引入dialog組件即可

<dialog visible="{{dialogVisible}}" showFooter="{{footerVisible}}" title="測試一下">
    <view class='dialog-body' slot="dialog-body">
      <view class='dialog-content'>申請獲取你微信綁定的手機號</view>
      <view class='dialog-footer' slot="dialog-footer">
        <button class='cancel-btn' bindtap="close">取消</button>
        <button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber" class='confirm-btn'>授權(quán)</button>
      </view>
    </view>
  </dialog>

dialog組件:

component下面新建dialog。注意是 component 不是 page ,因為要作為組件引入到頁面中

  dialog.wxml:

  需要傳入四個屬性

    visible:是否顯示彈窗

    title :標題

    showClose:是否顯示右上角關(guān)閉按鈕

    showFooter:是否顯示底部按鈕

<!--components/dialog/dialog.wxml-->
<view class='dialog-custom' wx:if="{{visible}}">
  <view class='dialog-mask' bindtap="clickMask"></view>
    <view class="dialog-main">
      <view class="dialog-container">
        <view class='dialog-container__title' wx:if="{{title.length>0}}">
          <view class='title-label'>{{ title }}</view>
          <view class='title-icon'>
            <image wx:if="{{showClose}}" bindtap='close' src='/images/close-btn.png'></image>
          </view>
        </view>
      <view class='dialog-container__body'>
        <slot name="dialog-body"></slot>
      </view>
      <view class='dialog-container__footer' wx:if="{{showFooter}}">
        <view class='dialog-container__footer__cancel' bindtap="close">取消</view>
        <view class='dialog-container__footer__confirm' bindtap='confirm'>確定</view>
      </view>
    </view>
  </view>
</view>

dialog.js

 

Component({
/**
* 組件的屬性列表
*/
properties: {
  visible: {
    type: Boolean,
    value: false
  },
  width: {
    type: Number,
    value: 85
  },
  position: {
    type: String,
    value: 'center'
  },
  title: {
    type: String,
    value: ''
  },
  showClose: {
    type: Boolean,
    value: true
  },
  showFooter: {
    type: Boolean,
    value: false
  },
},
/**
* 組件的初始數(shù)據(jù)
*/
data: {
},
options:{
  multipleSlots: true
},
/**
* 組件的方法列表
*/
methods: {
  clickMask() {
    this.setData({ visible: false });
  },
  close(){
    this.setData({ visible: false });
  },
  cancel() {
    this.setData({ visible: false });
    this.triggerEvent('cancel');
  },
  confirm() {
    this.setData({ visible: false });
    this.triggerEvent('confirm');
  }
}
})

dialog.json:聲明是組件就行 

{
  "component": true,
  "usingComponents": {}
}

dialog.wxss

  css可以根據(jù)自己喜好的樣式調(diào)整,注意mask遮罩層的z-index高一點,確保在最上層
