将分页号放在网址Vuejs中 [英] Place pagination number in url Vuejs

问题描述

我使用(Laravel，Vuejs和Bootstrap-Vue)进行分页，但是我需要在url中添加页码以使用历史记录.(用于后退按钮).这就是我到目前为止所拥有的.目标是地点页面nr.在网址中添加一个后退按钮.

I have an working pagination,using (Laravel,Vuejs and Bootstrap-Vue), but I need to add the page number in url to use history. (for back button). That's what I have till now. The goal is place page nr. in url,to have a back button.

{
    path: "/",  //here I will change it with "/:id"
    name: "Home",
    component: Home,
},

<b-pagination
    v-model="currentPage"
    :per-page="perPage"
    :total-rows="totalRows"
>
</b-pagination>   //this is my pagination nav, that takes currentPage from get Request

axios.get('/list',{
    params: {
        'page': this.currentPage,
        'per_page': this.perPage,
    },
})
.then(response => {
    this.perPage = response.data.per_page;
    this.totalRows = response.data.total;
})
.catch(function (error) {
    console.log('Error');
})  //and this is the get request

更新

我在响应中添加 router.push({path:"/"，query:{页面:this.currentPage}}); .我有路径，但是当我尝试访问页面2时，它在2和1中再次更改了id.我得到了重复的错误.

I add router.push({ path: "/", query: { page: this.currentPage } }); on my get response. I have the path ,but when I try to access page 2 , the id it'changed in 2, and in 1 again. and I got an error of duplicate.

NavigationDuplicated {_name:"NavigationDuplicated"，名称:"NavigationDuplicated"，消息:导航到当前位置("/?page = 1")不允许"

NavigationDuplicated {_name: "NavigationDuplicated", name: "NavigationDuplicated", message: "Navigating to current location ("/?page=1") is not allowed"

更新2 我几乎做到了，唯一无法使用的是活动类，在分页中，始终第1页是活动的.(内容，网址和currentPage变量已更改)

UPDATE 2 I almost made it, the only thing that don't work yet is active class, on pagination, always page 1 is active. (content,url and currentPage variable are changed)

watch:{
    currentPage() {
      this.$router
        .push({
          query: {
            ...this.$route.query,
            page: this.currentPage
          }
        })
        .catch(() => {});
    },
}

//In reseponse from axios:
this.currentPage = response.data.current_page;

推荐答案

基于

Based on this answer on how to replace the current query with another, and this answer on how you can simply ignore the error, i came up with the solution below.

当当前页面更改时，我使用计算属性自动更改URL，并根据答案添加一个空的 .catch 来抑制错误，因为该错误仍会导航很好.

I use a computed property to automatically change the URL when our current page changes, and based on the answer i add an empty .catch to our push to suppress the error, since it still navigates just fine.

修改

它完全忘记了用于更改URL的 b-pagination-nav 组件.我认为文档中的第一个示例可能对您很有用，因为这会通过?page = n 查询更改当前页面.

It completely forgot about the b-pagination-nav component, which is designed to change the URL. I think the first example in the documentation might be of use to you, since that changes the current page with a ?page=n query.

<template>
  <b-pagination
    v-model="currentPage"
    :per-page="perPage"
    :total-rows="totalRows"
  >
  </b-pagination>
  <b-table :items="items" :current-page="currentPage" :per-page="perPage">
  </b-table>
</template>

<script>
export default {
  created() {
    // Save the page for later use.
    // If our query isn't found, we default to page 1.
    const page = this.$route.query.page || 1;

    // fetch our data, this fetches all records and uses clientside pagination.
    fetch("https://example.com/movies.json")
      .then(resp => resp.json())
      .then(data => {
        this.items = data;

        // since b-pagination will change the currentPage to 1,
        // we need to change it back to the actual page after fetching our items.
        this.$nextTick(() => {
          this.currentPage = page;
        });
      });
  },
  computed: {
    totalRows() {
      return this.items.length;
    },
    currentPage: {
      get() {
        return this.$route.query.page || 1;
      },
      set(newPage) {
        // You could alternatively call your API here if you have serverside pagination

        this.$router
          .push({ query: { ...this.$route.query, page: newPage } })
          .catch(() => {});
      }
    }
  },
  data() {
    return {
      perPage: 5,
      items: []
    };
  }
};
</script>
