【问题描述】：

我有一个需要删除的***数组，我正在使用 Angular7，但我不确定如何从该数组中提取子对象。我想摆脱“***”级别，这样您就可以拥有具有属性的对象。任何帮助将不胜感激。

    "toplevel": [
        
            "SetName": "name1",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        ,
        
            "SetName": "name2",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        
    ]

这是我正在寻找的东西：

[
        
            "SetName": "name1",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        ,
        
            "SetName": "name2",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        
    ]

【问题讨论】：

包括一个示例输出。不清楚“从这个数组中拉出子对象”是什么意思。

发布的输出示例

只访问对象属性？ obj.topLevel

我遇到的问题是，当我尝试在 Angular 中进行查找时，我变得不确定，因为它没有在下一个级别查找。

【参考方案1】：

var jsonObject = 
    "toplevel": [
        
            "SetName": "name1",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        ,
        
            "SetName": "name2",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        
    ]
;

var innerArray = jsonObject.toplevel;

console.log(innerArray);
