gfs-loadingbar

状态加载

安装

    npm instsall gfs-loadingbar --save

使用

组件提供了多种loadingbar呈现方式，包括

• MaskBar 类似蒙层在页面中剧中展示加载状态效果，加载状态内容可自定义文字、图片均可

• LoadingBar 仿YouTube页面加载状态效果

    //引入loadingbar
    import {LoadingBar,MaskBar} from 'gfs-loadingbar'

    //初次使用需实例化loadingbar
    let loadingbar = new LoadingBar()

    //显示和隐藏loadingbar状态
    loadingbar.run()
    loadingbar.end()

React调用方式

与原生方式不同的是，此方式提供了redux middleware中间件、store状态机；并且能够与gfs-fetch、gfs-redux-bind-react配合使用；具体请参考例子：react-redux的使用方式

例子

• react+redux的使用方式

    //redux-react
    
    import React, { Component } from 'react'
    import ReactDom from 'react-dom'

    import LoadingBarComponent,{LoadingBar} from 'gfs-loadingbar/lib/react/LoadingBar'
    import {fetching} from 'gfs-loadingbar/lib/react/fetching'
    import {Connect} from 'gfs-loadingbar/lib/react/Connect'
    import FetchMiddleware from 'gfs-loadingbar/lib/react/FetchMiddleware'

    //或者这样

    //import {LoadingBarComponent,fetching,FetchMiddleware,LoadingBar,Connect} from 'gfs-loadingbar/lib/index.react';

    import { Provider,connect } from 'react-redux'
    import { createStore,applyMiddleware,combineReducers } from 'redux'


    //loadingbar实例，且页面中只能有一个
    let loadingbar = new LoadingBar()

    //action
    function fetchingAction(){
        
        //开始获取数据时显示loadingbar
        loadingbar.run()
        setTimeout( ()=>{
            //数据请求完成关闭loadingbar
            loadingbar.end()
        },2000)
    }

    //将组建内部写好的store合并到redux store中，并将提供的中间件注册好
    let store = createStore(combineReducers({fetching:fetching}),applyMiddleware(FetchMiddleware) )

    class Page extends Component {
        constructor(props) {
            super(props)
            
            fetchingAction()
        }

        render() {
            
            return (
                <Provider store={store}>
                    <div>
                        <Connect>
                            <LoadingBarComponent />
                        </Connect>
                    </div>
                </Provider>
            
            )
        }
    }

    export default function append(){
        window.onload = function(){
            let root = document.getElementById('root')
            if(root){
                ReactDom.render( <Page /> ,root)
            }
            
        }
    }
    

• 普通调用方式

    import {MaskBar,LoadingBar} from 'gfs-loadingbar'

    let $ = function() {
        return document.querySelectorAll(arguments[0])
    }

    let loadingBar = new LoadingBar()

    let maskBar = new MaskBar({
        text: '拼命加载中'
    })

    let timeout = null
    let masktimeout = null

    if ($('#j-loadingbar').length > 0) {
        $('#j-loadingbar')[0].onclick = function() {

            clearTimeout(timeout)
            //渲染loadingbar
            loadingBar.run()
            timeout = setTimeout(() => {
                //结束
                loadingBar.end()
            }, 4000)
        }
        $('#j-maskbar')[0].onclick = function() {
            clearTimeout(masktimeout)
            //渲染loadingbar
            maskBar.run()
            masktimeout = setTimeout(() => {
                //结束
                maskBar.end()
            }, 4000)
        }

    }
