react18 hooks自定义移动端Popup弹窗组件RcPop

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
                    })
                }

    </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

react18 hooks自定义移动端Popup弹窗组件RcPop

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
}

    useEffect(() => {
        props.visible && open()
        !props.visible && close()
    }, [props.visible])

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