我的代碼：

ajax: function (data, callback, settings) { 
    var out = []; 
    filterModel.Take = THERE_MUST_BE_FIRST_VALUE 
    filterModel.Skip = THERE_MUST_BE_SECOND_VALUE 
    var promise = filterService.getElectricityData(filterModel); 
    promise.then(function(data) { 
     for (var i = 0; i < data.length; i++) { 
      var model = []; 
      for (var j = 0; j < data[i].length; j++) { 
       model.push(data[i][j]); 
      } 
      out.push(model); 
     } 

Answer 1

您可以通過不同的方式

$.fn.dataTable.settings

// 240 
var start = $.fn.dataTable.settings[0]._iDisplayStart; 
// 5 
var size = $.fn.dataTable.settings[0]._iDisplayLength; 
// 245 
var end = start + size;

jQuery選擇$("datatableId_info").text()

/Showing (\d+) to (\d+) of (\d+) entries/.exec("Showing 241 to 245 of 744 entries"); 
Array [ "Showing 11 to 20 of 57 entries", "11", "20", "57" ] 

Answer 2

使用page.info()得到有關分頁表信息。

"ajax": function (data, callback, settings) { 
    var api = new $.fn.dataTable.Api(settings); 
    var info = api.page.info(); 

    filterModel.Take = info.start + 1; 
    filterModel.Skip = info.end; 

    // ... skipped ... 
}
