Question

我的代码如下：

var demoList = new Vue({
  el: '#demoList',
  data: {
    items: [{
      "id": 1,
      "name": "Tom"
    }, {
      "id": 2,
      "name": "Kate"
    }, {
      "id": 3,
      "name": "Jack"
    }, {
      "id": 4,
      "name": "Jill"
    }, {
      "id": 5,
      "name": "aa"
    }, {
      "id": 6,
      "name": "bb"
    }, {
      "id": 7,
      "name": "cc"
    }, {
      "id": 8,
      "name": "dd"
    }, {
      "id": 1,
      "name": "Tom"
    }, {
      "id": 2,
      "name": "Kate"
    }, {
      "id": 3,
      "name": "Jack"
    }, {
      "id": 4,
      "name": "Jill"
    }, {
      "id": 5,
      "name": "aa"
    }, {
      "id": 6,
      "name": "bb"
    }, {
      "id": 7,
      "name": "cc"
    }, {
      "id": 8,
      "name": "dd"
    }, ],
    loading: false,
    order: 1,
    searchText: null,
    ccn: null,
    currentPage: 0,
    itemsPerPage: 2,
    resultCount: 0
  },
  computed: {
    totalPages: function() {
      console.log(Math.ceil(this.resultCount / this.itemsPerPage) + "totalPages");
      return Math.ceil(this.resultCount / this.itemsPerPage);

    }
  },
  methods: {
    setPage: function(pageNumber) {
      this.currentPage = pageNumber;
      console.log(pageNumber);
    }
  },
  filters: {
    paginate: function(list) {
      this.resultCount = this.items.length;
      console.log(this.resultCount + " Result count");
      console.log(this.currentPage + " current page");
      console.log(this.itemsPerPage + " items per page");
      console.log(this.totalPages + " Total pages 2");
      if (this.currentPage >= this.totalPages) {
        this.currentPage = Math.max(0, this.totalPages - 1);
      }
      var index = this.currentPage * this.itemsPerPage;
      console.log(index + " index");
      console.log(this.items.slice(index, index + this.itemsPerPage));
      return this.items.slice(index, index + this.itemsPerPage);
    }
  }
});

a {
  color: #999;
}
.current {
  color: red;
}
ul {
  padding: 0;
  list-style-type: none;
}
li {
  display: inline;
  margin: 5px 5px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.16/vue.js"></script>
<div id="demoList">
  <div class="containerTable">
    <table class="table">
      <thead>
        <tr class="header">
          <th>
            <div><a @click="sortvia('provider_name')">Provider</a>
            </div>
          </th>
        </tr>
      </thead>
      <tbody>
        <tr v-for="item in items | paginate">
          <td>{{item.name}}</td>
        </tr>
      </tbody>
    </table>
  </div>
  <ul>
    <li v-for="pageNumber in totalPages">
      <a href="#" @click="setPage(pageNumber)">{{ pageNumber+1 }}</a>
    </li>
  </ul>
</div>

我试图创建一个带有vuejs的寻呼机，所以我很想知道是否有人可以指定一个如何制作这样的寻呼机的例子，如果可能的话“1-2-3-4-5 ... 55”？？，再次感谢您的帮助。

Answer 1

查看此代码：

https://jsfiddle.net/os7hp1cy/48/

HTML：

<ul>
    <li v-for="pageNumber in totalPages" 
        v-if="Math.abs(pageNumber - currentPage) < 3 || pageNumber == totalPages - 1 || pageNumber == 0">
    <a href="#" @click="setPage(pageNumber)"  
       :class="{current: currentPage === pageNumber, last: (pageNumber == totalPages - 1 && Math.abs(pageNumber - currentPage) > 3), first:(pageNumber == 0 && Math.abs(pageNumber - currentPage) > 3)}">
       {{ pageNumber+1 }}</a>
    </li>
</ul>

的CSS：

a.first::after {
  content:'...'
}

a.last::before {
  content:'...'
}

基本上，它只显示当前页面2页内的分页。然后它还会显示第1页和最后一页，并使用CSS在数字之前或之后放置"..."。因此，如果您在第10页，它将显示：

1... 8 9 10 11 12 ...21

Answer 2

由于此过滤器迁移https://vuejs.org/v2/guide/migration.html#Filters-Outside-Text-Interpolations-removed，我已将@ Jeff的代码分叉并为Vue 2制作了可用的版本。

将paginate方法移动到computed：

for file in *; do
   sed -i 's/ //g' $file
done

警告：我没有应用文本过滤器，只是首先使用分页。
