为什么我不能在对象数组中的for-in循环中访问对象属性？ [英] Why can’t I access object properties in a for-in loop over an array of objects?

问题描述

我目前正在使用SheetSU API从Google表格文件中读取数据。

I am currently utilizing the SheetSU API to read data from a Google Sheets file.

var members = Sheetsu.read("URL", {}, successFunc);

现在， successFunc 是一个函数将输入 data 输入 console.log（）给我。

For now, the successFunc is a function that takes the input data to console.log() to me.

数据导入如下：（14）{{..}，{..}，{..} ....} 和每个对象在这本词典中看起来像这样：

The data imports like this: (14){{..},{..},{..}....} and each object within this dictionary looks something like this:

0: {Name: "First Last", ID: "12536723", Status: "Member"}
1: {Name: "First Last", ID: "12371238", Status: "Member"}
...
14: {Name: "First Last", ID: "12341228", Status: "Member"}

我需要提取值姓名和 ID ，但是：

I need to pull out the values of Name and ID, however:

for (var x in data) {
    console.log(x)
}

= 0,1,2，...，14 （因为不是对象）

= 0, 1, 2, ..., 14 (as ints not objects)

for (var x in data) {
    console.log(x.Name)
}

= undefined，undefined，...，undefined

推荐答案

x 不是值它是索引比如0,1 ... 14，您可以使用的，或者在<$内使用 data [x] C $ C>在。

x is not a value It is a index like 0,1 ...14, you can use of for that or use data[x] inside in.

var data = [{
        Name: "First Last",
        ID: "12536723",
        Status: "Member"
    }, {
        Name: "First Last",
        ID: "12371238",
        Status: "Member"
    },
    {
        Name: "First Last",
        ID: "12341228",
        Status: "Member"
    }
]

for (var x in data) {

    console.log(data[x].Name); //x is not a value It is a index like 0,1 ...14

}

for (var x of data) {

    console.log(x.Name); // use of which prints x as object not index

}
