Question

当我尝试将Children添加到Json对象时我遇到了一个问题：

TypeError：ctrl.otsact.tests.push不是函数

脚本：

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

Json对象：

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

我想添加75个孩子来测试孩子

Answer 1

您的tests媒体资源是...... object，而不是array。测试应该是tests: []，而不是tests: {}。

Answer 2

在您的JSON测试中，不是数组而是对象，并且您无法推送到对象。所以这一行是错误的：

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

您必须将其更改为：

ctrl.otsact.tests[MYNEWID] = MYNEWOBJECT;

Angularjs将一个子对象添加到Json对象
