基於React.js實現PC桌面端自定義彈窗組件RLayer。html
前幾天有分享一個Vue網頁版彈框組件,今天分享一個最新開發的React PC桌面端自定義對話框組件。vue
RLayer 一款基於react.js開發的PC端自定義Layer彈出框組件。支持超過30+參數自由配置,經過輕巧的佈局設計、極簡的調用方式來解決複雜的彈出層功能,爲您呈上不同的彈窗效果。react
RLayer在設計開發之初有參考以前的VLayer組件,儘可能保持功能效果的一致性。android
如上圖:展現一些經常使用的基礎普通型彈窗功能。ios
在須要使用彈窗功能頁面引入rlayer組件。瀏覽器
// 引入組件RLayer import rlayer from './components/rlayer'
rlayer目前只支持函數式調用方式。 rlayer({...}) app
const showConfirm = () => { let $el = rlayer({ title: '標題信息', content: "<div style='color:#0070f3;padding:30px;'>這裏是確認框提示信息!</div>", shadeClose: false, zIndex: 1001, lockScroll: false, resize: true, dragOut: true, btns: [ { text: '取消', click: () => { $el.close() } }, { text: '肯定', style: {color: '#61dafb'}, click: () => { // ... } } ] }) }
注意:當彈窗類型爲 message | notify | popover 須要經過以下方式調用。dom
rlayer.message({...}) rlayer.notify({...}) rlayer.popover({...}) 函數
rlayer支持以下參數隨意搭配使用。佈局

其中utils/dom.js中是一些經常使用操做函數。
爲了方便在react.js中動態操做className,因而抽離了classnames函數。
classNames: function() { 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(' '); }
很是輕鬆方便的在react中實現各類動態操做className。
<div className="rlayer"></div> <div className={domUtils.classNames('rlayer', {'rlayer__closed': opt.close})}></div> <div className={domUtils.classNames('rlayer', opt.anim&&'anim-'+opt.anim)}></div> <div className={domUtils.classNames('rlayer', opt.icon)}></div>
...
react.js中經過ReactDOM.render方法將彈窗組件掛載到body上。
function RLayer(options = {}) { let $id = options.id let $dom = document.querySelector('#' + $id) if($id && $dom) return const div = document.createElement('div') const ref = React.createRef() document.body.appendChild(div) /* ReactDOM.render( <RLayerComponent {...options} remove={()=>{ ReactDOM.unmountComponentAtNode(div) document.body.removeChild(div) }} />, div ) */ ReactDOM.render(<RLayerComponent ref={ref} />, div) ref.current.open({ ...options, remove() { if(!ref.current) return ReactDOM.unmountComponentAtNode(div) document.body.removeChild(div) }}) // 返回彈框實例 return ref.current }
rlayer.js組件支持自定義拖拽區域 (drag:'#xxx'),是否拖動到窗口外 (dragOut:true)。還支持iframe彈窗類型 (type:'iframe')。
另外rlayer.js還支持彈窗置頂 (topmost:true),永遠保持當前窗口在最前。
好了,以上就是基於react.js開發PC端彈窗的相關介紹。但願你們能喜歡哈~~ ✍✍
