基于React18 Hooks实现手机端弹框组件RcPop
react-popup 基于react18+hook自定义多功能弹框组件。整合了msg/alert/dialog/toast及android/ios弹窗效果。支持20+自定义参数、组件式+函数式调用方式，全方位满足各种弹窗场景需求。
引入组件
在需要使用弹窗的页面引入组件。
// 引入自定义组件
import RcPop, { rcpop } from './components/rcpop'
RcPop支持 组件式+函数式 两种调用方式。
组件写法
<RcPop
visible={visible}
title="标题"
content="弹窗内容"
type="android"
shadeClose="false"
closeable
:btns="[
{text: '取消', click: () => setVisible(false)},
{text: '确认', style: {color: '#09f'}, click: handleOK},
]"
@onOpen={handleOpen}
@onClose={handleClose}
/>
<div>这里是自定义弹窗内容，优先级高于content内容。</div>
</RcPop>
函数写法
function handlePopup() {
rcpop({
title: '标题',
content: `<div style="padding:20px;">
<p>函数式调用：<em style="color:#999;">rcpop({...})</em></p>
</div>`,
btns: [
{
text: '取消',
click: () => {
// 关闭弹窗
rcpop.close()
}
},
{
text: '确认',
style: {color: '#09f'},
click: () => {
rcpop({
type: 'toast',
icon: 'loading',
content: '加载中...',
opacity: .2,
time: 2
})
}
}
]
})
}
- msg类型
- 自定义多按钮
rcpop({
title: '标题',
content: `<div style="color:#f90">
<p>显示自定义弹窗内容</p>
</div>`,
btns: [
{ text: '稍后提示' },
{ text: '取消', click: () => rcpop.close() },
{
text: '立即更新',
style: {color: '#09f'},
click: () => {
// ...
}
}
]
})
- ios弹窗类型
- android弹窗类型
- 长按/右键菜单
- 自定义内容
<RcPop
visible={visible}
closeable
xposition="top"
content="这里是内容信息"
btns={[
{text: '确认', style: {color: '#00d8ff'}, click: () => setVisible(false)},
]}
onOpen={()=> {
console.log('弹窗开启...')
}}
onClose={()=>{
console.log('弹窗关闭...')
setVisible(false)
}}
>
<div style={{padding: '15px'}}>
<img src={reactLogo} width="60" onClick={handleContextPopup} />
<h3 style={{color:'#f60', 'paddingTop':'10px'}}>当 content 和 自定义插槽 内容同时存在，只显示插槽内容。</h3>
</div>
</RcPop>
function handleContextPopup(e) {
let points = [e.clientX, e.clientY]
rcpop({
type: 'contextmenu',
follow: points,
opacity: 0,
btns: [
{text: '标记备注信息'},
{
text: '删除',
style: {color:'#f00'},
click: () => {
rcpop.close()
}
}
]
})
}
这次主打的是学习 React Hooks 开发自定义弹窗，之前也有开发过类似的弹层组件。

编码开发
在components目录下新建rcpop文件夹。
rcpop支持如下参数配置
// 弹窗默认参数
const defaultProps = {
// 是否显示弹出层
visible: false,
// 弹窗唯一性标识
id: null,
// 弹窗标题
title: '',
// 弹窗内容
content: '',
// 弹窗类型(toast | footer | actionsheet | actionsheetPicker | ios | android | androidSheet | contextmenu)
type: '',
// toast图标(loading | success | fail)
icon: '',
// 是否显示遮罩层
shade: true,
// 点击遮罩层关闭
shadeClose: true,
// 遮罩透明度
opacity: '',
// 自定义遮罩层样式
overlayStyle: {},
// 是否圆角
round: false,
// 是否显示关闭图标
closeable: false,
// 关闭图标位置(left | right | top | bottom)
closePosition: 'right',
// 关闭图标颜色
closeColor: '',
// 动画类型(scaleIn | fadeIn | footer | fadeInUp | fadeInDown)
anim: 'scaleIn',
// 弹窗出现位置(top | right | bottom | left)
position: '',
// 长按/右键弹窗(坐标点)
follow: null,
// 弹窗关闭时长，单位秒
time: 0,
// 弹窗层级
zIndex: 2023,
// 弹窗按钮组(text | style | disabled | click)
btns: null,
// 指定挂载的节点(仅对标签组件有效)
// teleport = () => document.body,
teleport: null,
// 弹窗打开回调
onOpen: () => {},
// 弹窗关闭回调
onClose: () => {},
// 点击遮罩层回调
onClickOverlay: () => {},
// 自定义样式
customStyle: {},
// 类名
className: null,
// 默认插槽内容
children: null
}
弹窗组件模板
const renderNode = () => {
return (
<div ref={ref} className={classNames('rc__popup', options.className, {'rc__popup-closed': closed})} id={options.id} style={{'display': !opened.current ? 'none' : undefined}}>
{/* 遮罩层 */}
{ isTrue(options.shade) && <div className="rcpopup__overlay" onClick={handleShadeClick} style={{'opacity': options.opacity, 'zIndex': oIndex-1, ...options.overlayStyle}}></div> }
{/* 窗体 */}
<div className="rcpopup__wrap" style={{'zIndex': oIndex}}>
<div
ref={childRef}
className={classNames(
'rcpopup__child',
{
[`anim-${options.anim}`]: options.anim,
[`popupui__${options.type}`]: options.type,
'round': options.round
},
options.position
)}
style={popStyles}
>
{ options.title && <div className="rcpopup__title">{options.title}</div> }
{ (options.type == 'toast' && options.icon) && <div className={classNames('rcpopup__toast', options.icon)} dangerouslySetInnerHTML={{__html: ToastIcon[options.icon]}}></div> }
{/* 内容 */}
{ options.children ? <div className="rcpopup__content">{options.children}</div> : options.content ? <div className="rcpopup__content" dangerouslySetInnerHTML={{__html: options.content}}></div> : null }
{/* 按钮组 */}
{ options.btns &&
<div className="rcpopup__actions">
{
options.btns.map((btn, index) => {
return <span className={classNames('btn', {'btn-disabled': btn.disabled})} key={index} style={btn.style} dangerouslySetInnerHTML={{__html: btn.text}} onClick={e => handleActions(e, index)}></span>
})
}
</div>
}
{ isTrue(options.closeable) && <div className={classNames('rcpopup__xclose', options.closePosition)} style={{'color': options.closeColor}} onClick={close}></div> }
</div>
</div>
</div>
)
}

// 暴露指定的方法给父组件调用
useImperativeHandle(ref, () => ({

return renderTeleport(options.teleport || mergeProps.teleport, renderNode())
})
react动态设置className，于是抽离封装了classNames函数。
// 抽离的React的classnames操作类
function classNames() {
var hasOwn = {}.hasOwnProperty
var classes = []
for (var i = 0; i < arguments.length; i++) {
var arg = arguments[i]
if (!arg) continue
var argType = typeof arg
if (argType === 'string' || argType === 'number') {
classes.push(arg)
} else if (Array.isArray(arg) && arg.length) {
var inner = classNames.apply(null, arg)
if (inner) {
classes.push(inner)
}
} else if (argType === 'object') {
for (var key in arg) {
if (hasOwn.call(arg, key) && arg[key]) {
classes.push(key)
}
}
}
}
return classes.join(' ')
}
非常方便的实现各种动态操作className类。
通过 createRoot 将弹窗组件挂载到body，实现函数式调用。
/**
* 函数式弹窗组件
* rcpop({...}) | rcpop.close()
*/
let popRef = createRef()
function Popup(options = {}) {
options.id = options.id || 'rcpopup-' + Math.floor(Math.random() * 10000)
// 判断id唯一性
let rnode = document.querySelector(`#${options.id}`)
if(options.id && rnode) return
const div = document.createElement('div')
document.body.appendChild(div)
const root = createRoot(div)
root.render(
<RcPop
ref={popRef}
visible={true}
{...options}
onClose={() => {
let node = document.querySelector(`#${options.id}`)
if(!node) return
root.unmount()
document.body.removeChild(div)
}}
/>
)
return popRef
}
