今天给小伙伴们分享一个全新开发的React自定义对话框最近RLayer。
rlayer 基于react.js开发的PC桌面端交互式弹出框组件。融合了Dialog、Message、Notification、ActionSheet、Toast、Popover、Popconfirm等多种功能。
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。
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: "<div style='color:#0070f3;padding:30px;'>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)</div>",
shadeClose: false,
zIndex: 1001,
lockScroll: false,
resize: true,
dragOut: true,
btns: [
{
text: '取消',
click: () => {
$el.close()
}
},
{
text: '确定',
style: {color: '#61dafb'},
click: () => {
handleInfo()
}
}
]
})
}

好了,以上就是基于React.js实现PC端弹出框组件,希望对大家有所帮助哈!
