使用Ajax将Daterangepicker参数传递给JQuery DataTable

Question

我已经使用带有Ajax的Jquery Datatable创建了一个表，它工作得很好，我创建了一个daterangepicker来过滤数据表。

我怎么能传递daterangepicker值筛选我的DataTable？

Answer 1

我在我的环境中重新创建了日期范围内的东西，但做了一个小改动。 我添加了一个数据范围更改事件来强制数据表运行ajax。

<script type="text/javascript"> 
    $(function() 
    { 
     var startdate = moment().subtract(29, 'days'); 
     var enddate = moment(); 
     function cb(startdate, enddate) { 
      $('#reservation span').html(startdate.format('YYYY-MM-DD') + ' ~ ' + enddate.format('YYYY-MM-DD')); 

此cb函数是一个回调函数，所以这是我认为是造成您的问题。没有办法保证它的第一次调用和数据表的ajax调用之间的时间。

由于每次更改日期时都会调用此函数，所以我摆脱了事件处理程序，并使用它来触发数据表ajax调用。

      $('#example').DataTable().draw(); 
     } 
     $('#reservation').daterangepicker({ 
      start: startdate, 
      end: enddate, 
      ranges: { 
       'Today': [moment(), moment()], 
       'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')], 
       'Last 7 Days': [moment().subtract(6, 'days'), moment()], 
       'Last 30 Days': [moment().subtract(29, 'days'), moment()], 
       'This Month': [moment().startOf('month'), moment().endOf('month')], 
       'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')] 
      } 
     }, cb) 

如上所述，我删除了最初放在这里的事件处理程序。

 cb(startdate, enddate); 

    }); 
</script> 

但因为我们要传递的日期即使其他的东西，如文本在搜索框中输入的，我真的不通过的日期在该事件处理程序。我在数据表ajax调用中获取日期。

<script type="text/javascript" charset="utf-8"> 
    $(document).ready(function() 
    { 
     // DataTable 
     $('#Show-Tables').DataTable({ 
      "processing": true, 
      "serverSide": true, 

我添加了延期加载。这意味着数据表已创建，但第一次获取数据的调用会被延迟，直到被其他操作触发为止。这使得在数据被提取之前创建日期选择器的时间。

      "deferLoading":0, 
      "pagingType": "full_numbers", 
      "ajax": { 
       "url": "dt-json-data.php", 
       "type": "POST", 
       //// Addded section to get the dates based on daterangepicker documentation 
       data: function (dtParms) { 
        var start = $('#reservation').data('daterangepicker').startDate.format(); 
        var end = $('#reservation').data('daterangepicker').endDate.format(); 
        // I put the dates in the search object but you can put it where you want inside the object. 
        dtParms.search.startDate = start; 
        dtParms.search.endData = end; 
        return dtParms; 
       }, 
       "dataSrc": "records" 
      }, 
      "columns": [ 
       { "data": "Tanggal" }, 
       { "data": "CustomerNo" }, 
       { "data": "CustomerName" }, 
       { "data": "Branch" }, 
       { "data": "Tot_Menit" }, 
       { "data": "Tot_call" } 
      ], 
      "autoWidth": true 
     }); 
    }); 
</script>I tested this against my environment so make sure I did not make misstates to make it fit yours.
