在javascript中，当将以下字符串转换为json对象时，我遇到一个错误，有人能帮我找到这个字符串的错误吗？

我应该怎么做才能将此字符串修复为vali1d javascript JSON对象

      txt = '{"Categories" : 
              [{"label":"petifores","id":"1"},
               {"label":"wedding cake","id":"2"},
               {"label":"shapes of cakes","id":"3"},
               {"label":"printable photos","id":"4","children":
               [{"label":"series","id":"7"},
                {"label":"kids","id":"8"},
                {"label":"animals","id":"9"},           
                {"label":"sport","id":"10"},
                {"label":"various pictures","id":"11"},
                {"label":"Cars","id":"12"},
                {"label":"girls","id":"13"},
                {"label":"artists","id":"14"}]
                {"label":"special events","id":"5"},
                {"label":"graduations","id":"6"}]}';

您缺少一个结束语

}

。我发现它是用

这是有效的

---

我删除了单引号。因此，如果要将其用作字符串，请将其再次添加

您缺少这些

}，

在

子项之后

将其更改为（请参见
}，
粗体）：

txt={“类别”：[{“标签”：“佩蒂弗雷斯”，“id”：“1”}，{“标签”：“婚礼蛋糕”，“id”：“2”}，{“标签”：“蛋糕形状”，“id”：“3”}，{“标签”：“可打印照片”，“id”：“4”，“儿童”：[{“标签”：“系列”，“id”：“7”}，{“标签”：“儿童”，“id”：“8”}，{“标签”：“动物”，“id”：“9”}，{“标签”：“运动”，“id”：“10”{“标签”：“各种图片”，“id”：“11”{“标签”：“汽车”，“id”：“id”：“12”}，{“标签”：“女孩”，“id”：“13”}，{“标签”：“艺术家”，“id”：“14”}]}，{“标签”：“特殊事件”，“id”：“5”}，{“标签”：“毕业”，“id”：“6”}]

检查以下位置的工作JSFIDLE:
我发现了您的错误，查看
{“标签”：“艺术家”，“id”：“14”}]{“标签”
并替换为
{“标签”：“艺术家”，“id”：“14”}]}，{“标签”

您可以使用此网站获取帮助：
是的，在关闭id 4的子项后，您错过了}

 "id":"14"}]  },  {"label":"special events","id":"5"}

您缺少id:14之后的结束}

{"Categories" : [{"label":"petifores","id":"1"},{"label":"wedding cake","id":"2"},{"label":"shapes of cakes","id":"3"},{"label":"printable photos","id":"4","children":[{"label":"series","id":"7"},{"label":"kids","id":"8"},{"label":"animals","id":"9"},{"label":"sport","id":"10"},{"label":"various pictures","id":"11"},{"label":"Cars","id":"12"},{"label":"girls","id":"13"},{"label":"artists","id":"14"}]},{"label":"special events","id":"5"},{"label":"graduations","id":"6"}]}

string now correct
在jsonlint.com上粘贴json对象，您将能够修复它。您可以在此处复制粘贴json:。我已经完成了，它说有错误。
