这里有一例供你参考: var _list = {}; for (var i = 0; i < checkedRow.length; i++) { _list["selectedIDs[" + i + "]"] = checkedRow[i].ID; } $.ajax({ url: '@Url.Action("SetCallBackStatus")', //data: { "selectedIDs": _list }, data: _list, dataType: "json", type: "POST", //traditional: true, success: function (responseJSON) { // your logic alert('Ok'); } });
