路由传值及获取参数,路由跳转,路由检测,this.$route.query和this.$route.params接收参数...

配置动态路由参数id:

routes: [

        // 动态路径参数 以冒号开头

        { path: '/user/:id', component: User }

      ]

html路由跳转:

<router-link to="/demo53/8">路径参数跳转</router-link>

①不带参数写法:

<router-link to="home">点我</router-link>

<router-link v-bind:to="'home'">点我</router-link>

<router-link :to="'home'">Home</router-link>

<router-link :to="{ path: 'home' }">Home</router-link>

② 带参数写法:

A: <router-link :to="{ name: 'user', params: { userId: 123 }}">User</router-link>

批注:路由配置格式:

{ path: '/user/:userId', name: 'user', component: User }

导航显示:/user/123 

B: <router-link :to="{ path: 'register', query: { plan: 'private' }}">Register</router-link>

批注:带查询参数

导航显示:/register?plan=private

js中使用的方式:  

① this.$router.push('xxx')                                                                  //字符串,这里的字符串是路径path匹配噢,不是router配置里的name

② this.$router.push({ path: 'home' })                                             //对象

③ this.$router.push({ name: 'user', params: { userId: 123 }})         // 命名的路由 这里会变成 /user/123

④ this.$router.push({ path: 'register', query: { plan: 'private' }})       // 带查询参数,变成 /register?plan=private

 

vue之this.$route.query和this.$route.params接收参数
this.$route.query
A页面传递参数peng=0
registerInfoThis.$router.push("/hrhi/psninfo/dynamic/" + data.row.pk_psndoc + '?funcode=60070psninfo&peng=0');
B页面接收参数
created() {
    this.penga = this.$route.query["peng"];            
  },

‘http://localhost:8080/linkParamsQuestion?age=18’

let age = this.$route.query.age; //问号后面参数会被封装进 this.$route.query;

this.$route.params
1、router/index.js
{
        path:'/mtindex',
        component: mtindex,
        //添加路由
        children:[
             {
                 path:"/detail",
                 name:'detail',
                 component:guessdetail
             }
        ]        

 },

2、传参数( params相对应的是name query相对应的是path)
this.$router.push({
name: ‘detail’, params:{shopid: item.id}
});


3、获取参数
this.$route.params.shopid


4、url的表现形式(url中没带参数)
http://localhost:8080/#/mtindex

 

 3.检测路由 

  watch:{
    '$route': function (to,from) {
      // 对路由变化作出响应...
    }
  }
或者
watch: {
    "$route": "routeChange",
},

methods: {
    routeChange(){
        console.log(this.$route.path);
    }
    
}

在 router-view上加上一个唯一的key,来保证路由切换时都会重新渲染触发钩子了

 

<router-view :key="key"></router-view>

computed: {
    key() {
        return this.$route.name !== undefined? this.$route.name + +new Date(): this.$route + +new Date()
    }
 }

HttpGet请求拼接url参数

    const query = {
      client_id: state.auth.clientID,
      redirect_uri: location.href,
      scope: 'public_repo'
    }

    const queryString = Object.keys(query)
      .map(key => `${key}=${encodeURIComponent(query[key] || '')}`)
      .join('&')

    return `http://github.com/login/oauth/authorize?${queryString}`

 

    return vue.$http.get(`https://api.github.com/search/issues?q=${data.keyword}+state:open+repo:${vue.$store.getters.repo}${label}&sort=created&order=desc&page=${data.currentPage}&per_page=${data.pageSize}`, {
      headers: {
        'Accept': 'application/vnd.github.v3.html'
      }
    })

 

const queryParse = (search = window.location.search) => {
  if (!search) {
    return {}
  } else {
    const queryString = search[0] === '?' ? search.substring(1) : search
    const query = {}
    queryString
      .split('&')
      .forEach(queryStr => {
        const [key, value] = queryStr.split('=')
        if (key) {
          query[decodeURIComponent(key)] = decodeURIComponent(value)
        }
      })
    return query
  }
}

const queryStringify = query => {
  const queryString = Object.keys(query)
    .map(key => `${key}=${encodeURIComponent(query[key] || '')}`)
    .join('&')
  return queryString
}
