基于Taro多端实践TaroPop:自定义模态框|dialog对话框|msg消息框|Toast提示
taro自定义弹出框支持编译到多端H5/小程序/ReactNative,还可以自定义弹窗类型/弹窗样式、多按钮事件/样式、自动关闭、遮罩层、弹窗显示位置及自定义内容模板
用法
▍在相应页面引入组件
import TaroPop from ‘@components/taroPop‘
import Taro from ‘@tarojs/taro‘ import { View, Text } from ‘@tarojs/components‘ // 引入自定义弹窗组件 import TaroPop from ‘@components/taroPop‘ export default class TaroPopDemo extends Taro.Component { ... render() { return ( <View className="taro-container"> ... {/* 引入弹窗模板 */} <TaroPop ref="taroPop" /> </View> ); } }
通过ref方式调用组件内show、close方法
this.refs.taroPop.show({...options})
this.refs.taroPop.close()
▍自定义弹窗模板内容(如下图)
只需把页面上的模板写成如下即可,调用方式还和上面一样
<TaroPop ref="taroPopTpl">
...
</TaroPop>
支持多种参数配置:
/** * @ 弹窗默认配置 */ static defaultProps = { isVisible: false, //弹窗显示 title: ‘‘, //标题 content: ‘‘, //内容 contentStyle: null, //内容样式 style: null, //自定义弹窗样式 skin: ‘‘, //弹窗风格 icon: ‘‘, //弹窗图标 xclose: false, //自定义关闭按钮 shade: true, //遮罩层 shadeClose: true, //点击遮罩关闭 opacity: ‘‘, //遮罩透明度 time: 0, //自动关闭时间 end: null, //销毁弹窗回调函数 position: ‘‘, //弹窗位置显示 btns: null, //弹窗按钮 [{...args}, {...args}] }
/** * 显示弹窗事件 */ show = (options) => { this.setState({ ...this.props, ...options, isVisible: true }) } /** * 关闭弹窗事件 */ close = () => { this.setState({...this.props}) this.timer && clearTimeout(this.timer) delete this.timer typeof this.state.end === ‘function‘ && this.state.end.call(this) } /** * 点击遮罩关闭 */ shadeClick = () => { if(!this.state.shadeClose) return this.close() }
◆ msg消息框提示
this.refs.taroPop.show({ content: ‘Taro自定义模态Modal弹窗‘, shadeClose: false, style: {backgroundColor: ‘rgba(0,0,0,.7)‘, borderRadius: 6}, contentStyle: {color: ‘#fff‘, fontSize: 12, padding: 12}, time: 3, opacity: .2, })
◆ Toast轻提示效果(success | error | info | loading四种图标)
let taroPop = this.refs.taroPop taroPop.show({ skin: ‘toast‘, content: ‘loading‘, icon: ‘loading‘, //success | info | error | loading shade: false, time: 3 })
◆ android弹窗效果
let taroPop = this.refs.taroPop taroPop.show({ skin: ‘android‘, title: ‘邮件提醒‘, content: ‘系统检测到你未开启新邮件提醒功能,为了保证新邮件能及时收到提醒,请前往系统 [设置] - [应用] 中开启‘, shadeClose: false, btns: [ { text: ‘取消‘, onClick() { taroPop.close() } }, { text: ‘前往设置‘, style: {color: ‘#4eca33‘}, onClick() { console.log(‘您点击了前往设置!‘) } } ] })
emmmm,看了如上展示及调用方式,是否觉得还不错哟!哈哈哈,这可是花了无数个日夜采坑的结果。
尤其是编译到reactNative端,各种千奇百怪的问题,有些抓狂~~
另外对于不同端的一些兼容性处理,需要判断各端环境并渲染相应模板,对于RN,则使用Modal
let taroEnv = process.env.TARO_ENV // 渲染窗体 if (taroEnv === ‘rn‘) { return ( <Modal transparent={true} visible={isVisible} onRequestClose={this.close}> {renderTpl} </Modal> ) }else if (taroEnv === ‘h5‘ || taroEnv === ‘weapp‘){ return isVisible && renderTpl }
另外在样式处理上也需注意RN端兼容性。

好了,以上就是taro自定义弹窗组件实现方式,希望能有帮助??~~
