移动端悬浮框可移动，可回弹，Vue and React

一，首先讲 React的悬浮框

示例，可参照链接

Demo文档，可参照链接

 

1. 安装

?

1	npm install suspend-button -S

2. 使用

?

import React, { Component } from 'react' import ReactDOM from 'react-dom' import SuspendButton from 'suspend-button'   class App extends Component {   render() {     return (       <SuspendButton></SuspendButton>     )   } }   ReactDOM.render(   <App />,   document.getElementById('container') )

　　

二，Vue的悬浮框 (可直接将代码进行拷贝到页面组件中)
