新老客户大回馈,云服务器低至5折

最近在做小程序的登录,需要同时获取用户手机号和头像昵称等信息,但是小程序又不支持单个接口同时获取两种数据,因此想到自定义一个弹窗,通过弹窗按钮触发获取手机号事件。记录一下。

具体代码如下:

业务代码中:

  在业务代码中引入dialog组件即可

  <dialog visible="{{dialogVisible}}" showFooter="{{footerVisible}}" title="测试一下">
    <view class='dialog-body' slot="dialog-body">
      <view class='dialog-content'>申请获取你微信绑定的手机号</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'>授权</button>
      </view>
    </view>
  </dialog>

dialog组件:

component下面新建dialog。注意是 component 不是 page ,因为要作为组件引入到页面中

  dialog.wxml:

  需要传入四个属性

    visible:是否显示弹窗

    title :标题

    showClose:是否显示右上角关闭按钮

    showFooter:是否显示底部按钮

<!--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'>确定</view>
      </view>
    </view>
  </view>
</view>
 
dialog.js
  
Component({
/**
* 组件的属性列表
*/
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
  },
},

/**
* 组件的初始数据
*/
data: {
 
},
options:{
  multipleSlots: true
},
/**
* 组件的方法列表
*/
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:声明是组件就行
 
{
  "component": true,
  "usingComponents": {}
}
 
 
dialog.wxss
  css可以根据自己喜好的样式调整,注意mask遮罩层的z-index高一点,确保在最上层
