Question

我的服务器端代码我正在尝试导出所选行。导出后，它导出所有记录但我想导出所选记录。对于选择我使用复选框

 while( $row=mysqli_fetch_array($queryRecords) )
     { 

             $nestedData=array();
     $nestedData[] = "<input type='checkbox' onclick='checkboxfn($(this));' 
       id='singleBox'  value='". 
              $index."'/>";
            $nestedData[]  = "<i class='mdi mdi-format-list-bulleted'></i>";
               $nestedData[]  = $index;
              $nestedData[] = $row["Designation"];
              $nestedData[] = $row["CompanyName"];
              $nestedData[] = $row["PersonalEmail"];
              $nestedData[] = $row["PersonalPhone"];
              $nestedData[] = $row["PersonalMobile"];
             $data[] = $nestedData;
             $index++;
      } 

      $json_data = array(
                  "draw"                => 1,  
                  "recordsTotal"    => intval( $totalRecords ), 
                    "recordsFiltered" => intval($totalRecords),
                   "data"            => $data   // total data array
                );
     echo json_encode($json_data);  // send data as json format

这是我的导出按钮代码。我可以导出所有记录而不选择任何记录，但我无法导出所选记录

 dom: 'lBfrtip',

buttons: [



    {
        extend: 'copyHtml5',

        exportOptions: {
            columns: [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21 ]
        }
    },
    {
        extend: 'excelHtml5',
        text: 'XLS',
        exportOptions: {
            columns: [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21]
        }
    },
    {
    extend:  'csvHtml5',
    exportOptions: 
    {
        columns: [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21]
    }
    },
    {
        extend: 'pdfHtml5',
        orientation: 'landscape',
    pageSize: 'A0',
        exportOptions: {
            columns: [7,8,9,10,11,12,13,14,15,16,17,18,19,20,21]
        }
    },

 ],


    columnDefs: [{
        "targets": 5,
        "orderable": true,


    }]

我的checkboxfn函数

    function checkboxfn(t)  
          { 

             if (t.is(':checked')) 
             {
                var index = rowIds.indexOf(t[0]['value']);  
                    if (index < 0) 
                    {
                        rowIds.push(t[0]['value']);

                    }   

             }else
             {  

                  var index = rowIds.indexOf(t[0]['value']);
                    if (index > -1) {
                        rowIds.splice(index, 1);
                    }            
            }

实际上，我在＆＃34; buttons.html5.min.js＆＃34;中找到了答案。我必须添加以下代码

对于CSV和复制，请添加以下代码

 for(i=0;i<l.length;i++)
      {

     if(rowIds.length != 0)
          {
     // I AM GETTING ERROR ON BELOW LINE
      var index = rowIds.indexOf(l[i].match(/\d+/)[0]);
console.log("Copy and CSV "+l[i].match(/\d+/)[0]);
console.log("Index "+index);

if (index < 0)
{
    //alert("dont export");
}
else
{

    l[i]=l[i].substr(l[i].indexOf(b.fieldSeparator) + 1);
    temp.push(l[i]);
}

}
  else
  {
 //removing the row id from the contact before export.
l[i]=l[i].substr(l[i].indexOf(b.fieldSeparator) + 1);
temp.push(l[i]);
  }

 }

并且对于Excel必须添加以下代码

 for (var f = 0, h = b.body.length; f < h; f++)

  if(rowIds.length != 0)
   {
  var index = rowIds.indexOf(b.body[f][0]);      
  console.log("Excel "+b.body[f][0]);
    if (index < 0)
    {
        //alert("dont export");
    }
    else
    {
        b.body[f].splice(0, 1);
        a += e(b.body[f]);
    }  
  }
 else
  {
   b.body[f].splice(0, 1);
   a += e(b.body[f]);
  }

 }
