javascript - DataTables+Datepicker 按日期范围过滤表格

问题描述

尝试使用两个有界日期选择器按日期范围实现 DataTables 过滤器。

我在 SO 看到过几个类似的问题，但没有一个有答案的人对我有用。

到目前为止，我设法实现了界面元素，但不知道如何将它们组合在一起以进一步进行。任何帮助表示赞赏。

var myTableData = 
  [
    {
      "id": "1",
      "name": "Tiger Nixon",
      "position": "System Architect",
      "salary": "$320,800",
      "start_date": "2011/04/25",
      "office": "Edinburgh",
      "extn": "5421"
    },
    {
      "id": "2",
      "name": "Garrett Winters",
      "position": "Accountant",
      "salary": "$170,750",
      "start_date": "2011/07/25",
      "office": "Tokyo",
      "extn": "8422"
    },
    {
      "id": "3",
      "name": "Ashton Cox",

$('.datepicker').datepicker();

var myDataTable = $('#staff').DataTable({

解决方案

我对你的代码做了一些修改。请参阅下面 JavaScript 片段中的注释，其中大部分位于底部，在您的var myDataTable = $('#staff').DataTable()声明下：

// I changed some of the start_date values to be more recent, just for testing.
var myTableData = [{
    "id": "1",
    "name": "Tiger Nixon",
    "position": "System Architect",
    "salary": "$320,800",
    "start_date": "2017/04/25",
    "office": "Edinburgh",
    "extn": "5421"
  },
  {
    "id": "2",
    "name": "Garrett Winters",
    "position": "Accountant",
    "salary": "$170,750",
    "start_date": "2018/07/25",
    "office": "Tokyo",
    "extn": "8422"
  },
  {
    "id": "3",
    "name": "Ashton Cox",
    "position": "Junior Technical Author",
    "salary": "$86,000",
    "start_date": "2019/01/12",
    "office": "San Francisco",
    "extn": "1562"
  },
  {
    "id": "4",
    "name": "Cedric Kelly",
    "position": "Senior Javascript Developer",
    "salary": "$433,060",
    "start_date": "2018/03/29",
    "office": "Edinburgh",
    "extn": "6224"
  },
  {
    "id": "5",
    "name": "Airi Satou",
    "position": "Accountant",
    "salary": "$162,700",
    "start_date": "2018/11/28",
    "office": "Tokyo",
    "extn": "5407"
  },
  {
    "id": "6",
    "name": "Brielle Williamson",
    "position": "Integration Specialist",
    "salary": "$372,000",
    "start_date": "2018/12/02",
    "office": "New York",
    "extn": "4804"
  },
  {
    "id": "7",
    "name": "Herrod Chandler",
    "position": "Sales Assistant",
    "salary": "$137,500",
    "start_date": "2018/08/06",
    "office": "San Francisco",
    "extn": "9608"
  }
];

var myDataTable = $('#staff').DataTable({
  sDom: 't',
  data: myTableData,
  columns: [{
      title: 'Name',
      data: 'name'
    },
    {
      title: 'Position',
      data: 'position'
    },
    {
      title: 'Office',
      data: 'office'
    },
    {
      title: 'Hire date',
      data: 'start_date'
    },
    {
      title: 'Salary',
      data: 'salary'
    }
  ]
});

// I instantiate the two datepickers here, instead of all at once like before.
// I also changed the dateFormat to match the format of the dates in the data table.
$("#startdate").datepicker({
  "dateFormat": "yy/mm/dd",
  "onSelect": function(date) {  // This handler kicks off the filtering.
    minDateFilter = new Date(date).getTime();
    myDataTable.draw(); // Redraw the table with the filtered data.
  }
}).keyup(function() {
  minDateFilter = new Date(this.value).getTime();
  myDataTable.draw();
});

$("#enddate").datepicker({
  "dateFormat": "yy/mm/dd",
  "onSelect": function(date) {
    maxDateFilter = new Date(date).getTime();
    myDataTable.draw();
  }
}).keyup(function() {
  maxDateFilter = new Date(this.value).getTime();
  myDataTable.draw();
});

// The below code actually does the date filtering.
minDateFilter = "";
maxDateFilter = "";

$.fn.dataTableExt.afnFiltering.push(
  function(oSettings, aData, iDataIndex) {
    if (typeof aData._date == 'undefined') {
      aData._date = new Date(aData[3]).getTime(); // Your date column is 3, hence aData[3].
    }

    if (minDateFilter && !isNaN(minDateFilter)) {
      if (aData._date < minDateFilter) {
        return false;
      }
    }

    if (maxDateFilter && !isNaN(maxDateFilter)) {
      if (aData._date > maxDateFilter) {
        return false;
      }
    }

    return true;
  }
);

<label>Start date:</label>
<input id="startdate" class="date_range_filter" />
<label>End date:</label>
<input id="enddate" class="date_range_filter" />
<table id="staff"></table>

我还删除了“过滤器”按钮，因为在此实现中不需要它。当您从日期选择器中选择日期时，该表应自动更新。
