簡介
RLayer.js 基於react.js開發的一款輕量級仿layer.js自定義彈窗元件。支援流暢拖拽、縮放、全屏及最大化
等功能。擁有精美UI及簡易API,讓複雜的彈窗互動變得簡單化。
rlayer支援Alert、Dialog、Message、Notification、ActionSheet、Toast、Popover、Popconfirm
等多種彈窗型別。
開發靈感來自之前分享的一個Vue.js彈框元件。

快速引入
// 引入彈窗元件RLayer
import rlayer from './components/rlayer'
通過rlayer({...})
即可快速呼叫一個彈窗例項。
const showConfirm = () => {
let $el = rlayer({
title: '標題內容',
content: "<div style='color:#0956f0;padding:30px;'>彈窗內容</div>",
shadeClose: true,
zIndex: 1111,
lockScroll: true,
resize: false,
dragOut: true,
btns: [
{
text: '關閉',
click: () => {
$el.close()
}
},
{
text: '確定',
style: {color: '#09f'},
click: () => {
// ...
}
}
]
})
}
一睹效果
提供了非常豐富的彈窗應用場景,滿足前端多樣化需求。

由於在react.js種動態操作class不是很方便,這裡就抽離了classnames類庫中的方法。
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(' ');
}
呼叫上面的方法就可以很容易的動態操作類了。
classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'
// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'
// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'
rlayer.js預設標題區是可以拖拽的,不過也可以根據需要自定義拖拽手柄drag: '#xxxx'
,或者設定drag: false
來禁止彈窗拖拽功能。設定dragOut: true
還可以將彈窗拖拽到瀏覽器外部。
設定fullscreen: true
預設顯示全屏彈窗。maximize: true
開啟最大化按鈕。
