vue-router 2.0 跳转之router.push()用法说明

// 字符串
router.push('home')

// 对象
this.$router.push({path: '/login?url=' + this.$route.path});

// 命名的路由
router.push({ name: 'user', params: { userId: 123 }})

// 带查询参数，变成/backend/order?selected=2
this.$router.push({path: '/backend/order', query: {selected: "2"}});

// 设置查询参数
this.$http.post('v1/user/select-stage', {stage: stage})
   .then(({data: {code, content}}) => {
      if (code === 0) {
        // 对象
        this.$router.push({path: '/home'});
      }else if(code === 10){
        // 带查询参数，变成/login?stage=stage
        this.$router.push({path: '/login', query:{stage: stage}});
      }
});

// 设计查询参数对象
let queryData = {};
if (this.$route.query.stage) {
  queryData.stage = this.$route.query.stage;
}
if (this.$route.query.url) {
  queryData.url = this.$route.query.url;
}
this.$router.push({path: '/my/profile', query: queryData});

this.$router.push({path: '/home', replace: true})
//如果是声明式就是像下面这样写：
<router-link :to="..." replace></router-link>
// 编程式:
router.replace(...)

beforeRouteLeave (to, from, next) {
  if (to.name === 'login') {
    next(false)// 不跳转
  } else {
    next() // 跳转到另一个路由
  }
}
