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 /* 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; }
