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}}" style="margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";"> <!--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
/* components/dialog/dialog.wxss */.dialog-custom { width: 100vw; height: 100%; position: absolute; left: 0; top: 0; z-index: 9999;}.dialog-mask { position: fixed; top: 0; left: 0; right: 0; bottom: 0; z-index: 10000; width: 100vw; height: 100%; background: rgba(0, 0, 0, 0.3);}.dialog-main { position: fixed; z-index: 10001; top: 50%; left: 0; right: 0; width: 85vw; height: auto; margin: auto; transform: translateY(-50%);}.dialog-container { margin: 0 auto; background: #fff; z-index: 10001; border-radius: 3px; box-sizing: border-box; padding: 40rpx;}.dialog-container__title { width: 100%; height: 50rpx; line-height: 50rpx; margin-bottom: 20rpx; position: relative;}.dialog-container__title .title-label{ display: inline-block; width: 100%; height: 50rpx; line-height: 50rpx; font-size: 36rpx; color: #000; text-align: center;}.dialog-container__title .title-icon{ width: 34rpx; height: 50rpx; position: absolute; top: 0; right: 0;}.dialog-container__title .title-icon image{ width: 34rpx; height: 34rpx;}.dialog-container__body { padding-top: 10rpx; font-size: 32rpx; line-height: 50rpx;}.dialog-container__footer { height: 76rpx; line-height: 76rpx; font-size: 32rpx; text-align: center; border-top: 1px solid #f1f1f1; position: absolute; bottom: 0; left: 0; right: 0;}.dialog-container__footer .dialog-container__footer__cancel { width: 50%; color: #999; display: inline-block;}.dialog-container__footer .dialog-container__footer__cancel::after{ position: absolute; right: 50%; bottom: 0; content: ''; width: 2rpx; height: 76rpx; background: #f1f1f1;}.dialog-container__footer .dialog-container__footer__confirm { color: #3B98F7; width: 50%; display: inline-block; text-align: center;}
