RLayer.js 一款基于react.js构建的pc桌面端自定义弹出层组件。拥有精致的UI及极简的调用方式,支持顺滑拖拽、缩放及最大化
等功能,让复杂的弹框场景变得简单化。
支持Alert、Dialog、Message、Notification、ActionSheet、Toast、Popover、Popconfirm
等弹窗类型。
灵感来源于之前开发的一款vue pc端自定义弹框组件VLayer。
基于Vue.js PC桌面端弹出框组件|vue自定义弹层组件|vue模态框
// 引入组件RLayer
import rlayer from './components/rlayer'
使用rlayer({...options})
即可快速调用一个弹框实例。
const showAlert = () => {
let $el = rlayer({
title: '标题',
content: "<div style='color:#09f;padding:50px;'>弹窗内容信息</div>",
shadeClose: true,
zIndex: 2121,
lockScroll: true,
resize: false,
dragOut: true,
btns: [
{
text: '取消',
click: () => {
$el.close()
}
},
{
text: '确定',
style: {color: '#09f'},
click: () => {
// ...
}
}
]
})
}
提供了非常多的常用弹窗应用场景。

有些react.js中动态操作class不是很方便,没有像vue中操作那么简单。
这里特意抽离了classnames库中的classNames类。
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(' ');
}
下面就很容易的实现各种动态class操作了。
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'
好了,到这里就基本介绍差不多了。后面有个实例项目也会用到弹窗功能,届时也会分享出来。✍💪
最后附上一个vue.js自定义组件
