解决vue页面刷新或者后退参数丢失的问题

export default {
    data () {
      return {
        searchForm:{
          project_name:'',
          status:'',
          city:'',
          round:'',
          fund:'',
          charge:'',
          page: 1
        },
      },
      beforeRouteLeave(to, from, next){
      //打开详情页（或者下一个任意界面）之前，把筛选条件保存到localStorage，如果离开列表页并且打开的不是详情页则清除，也可以选择不清除
      if (to.name == 'Detail') {
        let condition = JSON.stringify(this.searchForm)
        localStorage.setItem('condition', condition)
      }else{
        localStorage.removeItem('condition')
      }
      next()
    },
    created(){
      //从localStorage中读取条件并赋值给查询表单
      let condition = localStorage.getItem('condition')
      if (condition != null) {
       this.searchForm = JSON.parse(condition)
      }
      this.$http.get('http://example.com/api/test', {params: this.searchForm})
      .then((response)=>{
        console.log(response.data)
      }).catch((error)=>{
        console.log(error)
      })
    }
  }
}
