使用 dtOptions 访问 angularjs 数据表中的 json 数据

Question

我正在使用 Angular 数据表和 jquery 数据表来填充我的 json 数据。我无法使用 DTColumnBuilder.withnewColumn() 访问 json 数据。试了好几次都搞不定，谁能帮帮我。

$scope.dtOptions = DTOptionsBuilder.fromFnPromise( multishiftService.fetchfunds())
.withPaginationType('extStyle')
.withDOM ( '<"top"iflp<"clear">>rt<"bottom"iflp<"clear">>' )
.withOption('bFilter', false)
.withOption('bInfo',false);



 $scope.dtColumns = [ 

    DTColumnBuilder.newColumn('contracts.contracts[0].productGroup').withTitle('Fund Name'),
    DTColumnBuilder.newColumn(null).withTitle('Transfer %')

  ];




  $scope.dtColumnDefs = [

        DTColumnDefBuilder.newColumnDef(0).renderWith(function(data, type, full) {
                return '<a href="#">' + data + '</a>';

        }),
        DTColumnDefBuilder.newColumnDef(1).renderWith(function(data, type, full) {
            return '<input class="inputs txtFunds dt-body-center" type="text"/> %';
        })
    ];

我的html代码是：

<table datatable="" dt-options="dtOptions" dt-columns="dtColumns" dt-column-defs="dtColumnDefs" cellspacing="0" width="100%" class="display fundsTable row-border hover">
   </table>

默认情况下，Angular-datatables 会寻找一个数组作为数据。 如果您的数据嵌套在一个对象中，那么您需要提供AjaxDataProp。

在您的情况下，您应该在 DT 选项中添加 withDataProp：

$scope.dtOptions = DTOptionsBuilder.fromFnPromise( multishiftService.fetchfunds())
    .withDataProp('contracts.contracts')
    .withPaginationType('extStyle')
    .withDOM ( '<"top"iflp<"clear">>rt<"bottom"iflp<"clear">>' )
    .withOption('bFilter', false)
    .withOption('bInfo',false);

此外，您在定义列时不需要指定嵌套属性：

$scope.dtColumns = [
    DTColumnBuilder.newColumn('productGroup').withTitle('Fund Name'),
    DTColumnBuilder.newColumn(null).withTitle('Transfer %')
];
