带分页的 Vuejs 网格 (Pagination)

  • 772

官方示例中有一个Grid：
How can I make it "paginated"？
数据总是可以是不同的数量。

Vue.component('demo-grid', {
  template: '#grid-template',
  props: {
    data: Array,
    columns: Array,
    filterKey: String
  },
  data: function () {
    var sortOrders = {}
    this.columns.forEach(function (key) {
      sortOrders[key] = 1
    })
    return {
      sortKey: '',
      sortOrders: sortOrders
    }
  },
  computed: {
    filteredData: function () {
      var sortKey = this.sortKey
      var filterKey = this.filterKey && this.filterKey.toLowerCase()
      var order = this.sortOrders[sortKey] || 1
      var data = this.data
      if (filterKey) {
        data = data.filter(function (row) {
          return Object.keys(row).some(function (key) {
            return String(row[key]).toLowerCase().indexOf(filterKey) > -1
          })
        })
      }
      if (sortKey) {
        data = data.slice().sort(function (a, b) {
          a = a[sortKey]
          b = b[sortKey]
          return (a === b ? 0 : a > b ? 1 : -1) * order
        })
      }
      return data
    }
  },
  filters: {
    capitalize: function (str) {
      return str.charAt(0).toUpperCase() + str.slice(1)
    }
  },
  methods: {
    sortBy: function (key) {
      this.sortKey = key
      this.sortOrders[key] = this.sortOrders[key] * -1
    }
  }
})

    @OlegShleif 的变体适用于 vue2：

    // register the grid component
Vue.component('demo-grid', {
  template: '#grid-template',
  props: {
    data: Array,
    columns: Array,
    filterKey: String,
    rowsPerPage: Number
  },
  data: function() {
    var sortOrders = {}
    this.columns.forEach(function(key) {
      sortOrders[key] = 1
    })
    return {
      sortKey: '',
      sortOrders: sortOrders,
      startRow: 0
    }
  },
  computed: {
    filteredData: function() {
      var sortKey = this.sortKey
      var filterKey = this.filterKey && this.filterKey.toLowerCase()
      var order = this.sortOrders[sortKey] || 1
      var data = this.data

      this.startRow = 0 // reset to start

      if (filterKey) {
        data = data.filter(function(row) {

  2. 下午好尤金，这是一个分页的例子

    HTML

    <table>
  <thead>
    <tr>
      <th v-for="key in columns">
        {{key | capitalize}}
      </th>
    </tr>
  </thead>
  <tbody>
    <tr v-for="entry in data | limitBy rowsPerPage startRow">
      <td v-for="key in columns">
        {{entry[key]}}
      </td>
    </tr>
  </tbody>
</table>
<div id="page-navigation">
  <button @click=movePages(-1)>Back</button>
  <p>{{startRow / rowsPerPage + 1}} out of {{Math.ceil(data.length / rowsPerPage)}}</p>
  <button @click=movePages(1)>Next</button>
</div>

    JS

    var baseData = [{
  name: 'Chuck Norris',
  power: Infinity
}, {
  name: 'Bruce Lee',
  power: 9000
}, {
  name: 'Jackie Chan',
  power: 7000
}, {
  name: 'Jet Li',
  power: 8000
}];
var gridData = Array(100).fill(null).map(function() {
  return Object.assign({}, baseData[Math.floor(Math.random() * 4)]);
});

// register the grid component
Vue.component('grid', {
  template: '#grid-template',
  props: {
    data: Array,
    columns: Array,
    movePages: Function,
    startRow: Number,
    rowsPerPage: Number
  }
});

// Create the view-model
var gridViewModel = new Vue({
  el: '#grid-view-model',
  data: {
    searchQuery: '',
    gridColumns: ['name', 'power'],
    gridData: gridData,
    startRow: 0,
    rowsPerPage: 10
  },
  methods: {
    movePages: function(amount) {
      var newStartRow = this.startRow + (amount * this.rowsPerPage);
      if (newStartRow >= 0 && newStartRow < gridData.length) {
        this.startRow = newStartRow;
      }
    },
    resetStartRow: function() {
      this.startRow = 0;
    }
  },
  filters: {
    orderByBusinessRules: function(data) {
      return data.slice().sort(function(a, b) {
        return a.power - b.power;
      });
    }
  }
})
