超赞 React.js 桌面端自定义弹窗组件RLayer

看名称就能联想到前端界有名的弹窗layer.js,其实在设计开发之初就有借鉴layer插件实现思想。

超赞 React.js 桌面端自定义弹窗组件RLayer

功能

  • 提供函数式调用方法 rlayer({…})
  • 12 弹框类型 (toast | footer | actionsheet | actionsheetPicker | android/ios | contextmenu | drawer | iframe | message | notify | popover)
  • 7 种弹窗动画 (scaleIn | fadeIn | footer | fadeInUp | fadeInDown | fadeInLeft | fadeInRight)

引入组件

在需要使用组件的页面引入rlayer组件。

// 引入弹框组件RLayer
import rlayer from \'./components/rlayer\'

快速使用

引入后即可通过函数rlayer({…})来调用即可。

支持超过30 个参数自由搭配,快速实现定制化的各种效果。

// msg消息
const showMsg = () => {
    rlayer({
        content: "这是一条msg消息提示",
        shadeClose: false,
        xclose: false,
        time: 2
    })
}

// confirm询问框
const showConfirm = () => {
    let $el = rlayer({
        title: \'询问标题\',
        content: "
确认框(这里是确认框提示信息,这里确认框提示信息,这里是确认框提示信息)
",
        shadeClose: false,
        zIndex: 1001,
        lockScroll: false,
        resize: true,
        dragOut: true,
        btns: [
            {
                text: \'取消\',
                click: () => {
                    $el.close()
                }
            },
            {
                text: \'确定\',
                style: {color: \'#61dafb\'},
                click: () => {
