假设我有这个 json

{"widget": {
    "debug": "on",
    "window": {
        "title": "Sample Konfabulator Widget",
        "name": "main_window",
        "width": 500,
        "height": 500
    },
    "image": { 
        "src": "Images/Sun.png",
        "name": "sun1",
        "hOffset": 250,
        "vOffset": 250,
        "alignment": "center"
    },
    "text": {
        "data": "Click Here",
        "size": 36,
        "style": "bold",
        "name": "text1",
        "hOffset": 250,
        "vOffset": 100,
        "alignment": "center",
        "onMouseUp": "sun1.opacity = (sun1.opacity / 100) * 90;"
    }
}}

我有这些对象的列表并像这样放入变量

var myobjects = data

其中包含上述对象的列表

现在工作正常，但现在我有一个问题。我现在有一个包含这些对象的父对象，而不是直接获取对象列表

"id": "21"
"myobject": 
{
{"widget": {
    "debug": "on",
    "window": {
        "title": "Sample Konfabulator Widget",
        "name": "main_window",
        "width": 500,
        "height": 500
    },
    "image": { 
        "src": "Images/Sun.png",
        "name": "sun1",
        "hOffset": 250,
        "vOffset": 250,
        "alignment": "center"
    },
    "text": {
        "data": "Click Here",
        "size": 36,
        "style": "bold",
        "name": "text1",
        "hOffset": 250,
        "vOffset": 100,
        "alignment": "center",
        "onMouseUp": "sun1.opacity = (sun1.opacity / 100) * 90;"
    }
}}
}

而不是获取子对象列表，我现在有父对象列表data

如何像以前一样从父对象列表中获取子对象列表

就像是

var childobjects = data.childobjects

我想要那个，因为我已经编码了模板，只有当我有对象的直接列表时才可以使用

你想展平对象数组吗？

// suppose data is like this:
var data = [
    { id: 1, myobject: {widgets:'',whatever:''}},
    { id: 5, myobject: {widgets:'',whatever:''}},
    { id: 23, myobject: {widgets:'',whatever:''}}
]

然后这段代码：

var myobjects = [];

for (key in data) {
  myobjects.push(data[key].myobject);
}

将离开myobjects等于：

[
    {widgets:'',whatever:''},
    {widgets:'',whatever:''},
    {widgets:'',whatever:''}
]

我认为这是你需要的：

<script type="text/javascript">
var parents = [{"id": "21",
                "myobject": 
                 {"widget": {
                  "debug": "on",
                  "window": {
                             "title": "Sample Konfabulator Widget",
                              "name": "main_window",
                              "width": 500,
                              "height": 500
                             },
