微信小程序封装自定义弹窗的实现代码
2020-11-27
来源：榕意旅游网
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
