JavaScript代码

hash体式格局

class HashRoute {
    setRoute() {
        const commandObj = {
            one: 'page one',
            two: 'page two',
            three: 'page three'
        }
        const hashRoute = location.hash ? location.hash.slice(2) : 'one'
        let re = commandObj[hashRoute]

        document.getElementById('hashContent').innerHTML =  re ? re : 'page not find'
    }

    skip(path) {
        window.location.hash= `#/${path}`
    }

    init() {
        window.addEventListener('DOMContentLoaded', this.setRoute)

        // 1.直接变动浏览器地点，在最背面增添或转变#hash； 
        // 2.经由过程转变location.href 或 location.hash的值； 
        // 3.经由过程触发点击带锚点的链接； 
        // 4.浏览器行进退却能够致使hash的变化，条件是两个网页地点中的hash值差别
        window.addEventListener('hashchange', this.setRoute)
    }
}

const hashRoute = new HashRoute()

hashRoute.init()

history 体式格局

浏览器端代码

// 服务端有用
class HistoryRoute {
    constructor() {
        this.currentPath = ''
    }

    renderView(component) {
        const route = {
            pushStateOne: 'route pushState one',
            pushStateTwo: 'route pushState two',
            pushStateThree: 'route pushState three',
            replaceState: 'route replaceState',
            go: 'route go',
            forward: 'route forward',
            back: 'route back',
            notFind: 'not find',
        }
        document.getElementById('historyContent').innerHTML = route[component]
    }

    // 这里一切触及的跳转都用js体式格局，不采纳a标签(采纳a标签请设置阻拦)
    skip(path) {
        const commandObj = {
            pushStateOne: () => {
                history.pushState({ path }, path,path)
                this.renderView(path)
            },
            pushStateTwo: () => {
                history.pushState({ path }, path, path)
                this.renderView(path)
            },
            pushStateThree: () => {
                history.pushState({ path }, path, path)
                this.renderView(path)
            },
            replaceState: () => {
                // 是用来修正当前的history实体而不是建立一个新的,比方连转递次为1，2，3，1实行replaceState(2),再实行back()，返回1，而不是3
                history.replaceState({ path }, path, path)
                this.renderView(path)
            },
            go: () => {
                history.go(2)
                this.renderView('go')
            },
            forward: () => {
                history.forward()
                this.renderView('forward')
            },
            back: () => {
                history.back()
            },

        }

        this.currentPath = path;
        commandObj[path]()
    }

    init() {
        window.addEventListener('DOMContentLoaded', () => {
            // 针对F5革新题目:
            // 1.能够运用？背面跟参数情势
            // 2.一致进口应用疏忽地点体式格局（后端设置 /page/:path 疏忽page后跟的一切地点，经由过程前端去要求page后的对应路由数据，以下）

            const path = location.href.split('/page/') 
            this.skip(path[1])
        })

        // 挪用history.pushState()或history.replaceState()不会触发popstate。
        // 只要在用户点击行进回退按钮，(或history.back()，forward，go)
        window.addEventListener('popstate', (event) => {
            console.log('popstate', this.currentPath, event.state);
            const { state } = event
            if (state && state.path) {
                this.renderView(state.path)
            } else {
                this.renderView('404')
            }
        })
    }
}

const historyRoute = new HistoryRoute()

historyRoute.init();

服务器端

// 连系前端，能够用以下体式格局处置惩罚
router.get('/page/:path', (ctx, next) => {
    ctx.response.type = 'html';
    // 此处的singlePageRoute.html为单页面html容器，即安排本文中的一切代码文件
    ctx.response.body = fs.createReadStream('./dist/public/files/singlePageRoute.html');
    return next();
})
