前言
RLayer.js 一个 react 构建的桌面 PC 端 自定义 Dialog 组件 。 内置 30+ 参数配置、10+ 弹框类型、7+ 动画成果
,提供极简的接口及清新的皮肤。领有顺滑般 最大化 / 缩放 / 拖拽
体验!
RLayer在设计及开发上参考了之前的 VLayer 弹出框组件。在成果上放弃一致性。
vlayer一款 vue2.x 开发的网页弹框组件,感兴趣的能够去看看这篇文章。

引入应用
在须要用到弹出框的页面引入 rlayer 组件即可。
// 引入 RLayer
import rlayer from './components/rlayer';
提供了十分繁难的调用写法 rlayer({...})
showConfirm = () => {
let $rlayer = rlayer({
title: '题目信息',
content: "<div style='color:#0070f3;padding:50px;'> 显示弹窗内容。</div>",
shadeClose: true,
zIndex: 2021,
lockScroll: true,
resize: true,
dragOut: false,
btns: [
{
text: '勾销',
click: () => {$rlayer.close()
}
},
{
text: '确定',
style: {color: '#09f'},
click: () => {// ...}
}
]
})
}
留神:如果弹框类型为 message|notify|popover
,则须要应用如下调用形式。
rlayer.message({...})
rlayer.notify({...})
rlayer.popover({...})
一睹成果
编码实现

动静 className
在 react.js 中动静绑定 class 类名。有如下几种罕用办法。
// 字符串拼接
<i className={["rlayer"+" "+item.icon]} ></i>
// 判断
<i className={["rlayer",isOK ? item.icon : ''].join('')} ></i>
// ES6 模板字符串
<i className={`rlayer ${isOK ? item.icon : ''}`} ></i>
这种办法简略的还行,简单的拼接就麻烦,而且会生成很多莫名的空格。
这里采纳了 React classnames 库。
看看如下的应用办法,就晓得有多不便。
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 组件反对自定义拖拽把手 drag:'#aaa'
,是否能够拖动到窗口内部 dragOut:true
。
另外还反对 iframe 弹框,只需设置 type:'iframe'
,content 传入网址就行。
配置 fullscreen:true
即可关上弹框就显示全屏。
好了,基于 React.js 开发 pc 端弹窗组件就分享到这里。心愿对大家有些帮忙哈!✍✍
