AngularJS將子對象添加到Json對象

Question

當我嘗試將Children添加到Json Object時出現問題：

TypeError：ctrl.otsact.tests.push不是函數

劇本：

function addOTSACT() {
        var data = {
            'date': '',
            'subjects': angular.copy(ctrl.otsactSubjectsCopy)
        }
        $('.dateField').datepicker({
        changeMonth: true,
        changeYear: true
        });
        ctrl.otsact.tests.push({});
    }

傑森對象：

   "ACT":{  
      "name":"ACT",
      "tests":{  
         "73":{

我想增加75個孩子來測試孩子

Answer 1

您的tests屬性是...一個object ，而不是一個array 。 測試應該是tests: [] ，而不是tests: {} 。

Answer 2

在您的JSON測試中，不是數組而是對象，因此您不能推送到對象。 所以這行是錯誤的：

ctrl.otsact.tests.push({});

您必須將其更改為：

ctrl.otsact.tests[MYNEWID] = MYNEWOBJECT;
