将新属性添加到Node中的现有JSON数组

I want to insert one or more attributes into the existing JSON. Here's the basic format.

我想在现有的JSON中插入一个或多个属性。这是基本格式。

var resultData = {
        "result" : "OK",
        "data" : [
            {"name1" : "value1"},
            {"name2" : "value2"}
        ]
    };

And I want to insert {"name3" : "value3"} into the end of the data field. The result should look like this.

我想在数据字段的末尾插入{“name3”：“value3”}。结果应该是这样的。

var resultData = {
        "result" : "OK",
        "data" : [
            {"name1" : "value1"},
            {"name2" : "value2"},
            {"name3" : "value3"}
        ]
    };

How do I do this? I know how to add an attribute to the resultData or resultData.result or resultData.data.name1 or etc. However, I couldn't find a way to add an attribute to the resultData.data.

我该怎么做呢？我知道如何将属性添加到resultData或resultData.result或resultData.data.name1等。但是，我找不到向resultData.data添加属性的方法。

You can do:

你可以做：

resultData.data[3] = {"name4" : "value4"}

That would add a new element on the 4th position. And like Sigorilla just answered before me, .push() will always add it one the end of your object.

这将在第4位增加一个新元素。就像Sigorilla刚刚在我面前回答的那样，.push（）总会在你对象的末尾添加它。

You don't need to do resultData["data"].push() though, as you can just use resultData.data.push() I think.

你不需要做resultData [“data”]。push（），因为你可以使用resultData.data.push（）我想。

#2

You can use push(): resultData["data"].push({"name3": "value3"});

你可以使用push（）：resultData [“data”]。push（{“name3”：“value3”}）;
