如何在 JavaScript 中迭代对象? [英] How to iterate object in JavaScript?

问题描述

我有这个对象.我想在 JavaScript 中迭代这个对象.这怎么可能?

I have this object. I want to iterate this object in JavaScript. How is this possible?

var dictionary = {
    "data": [
        {"id":"0","name":"ABC"},
        {"id":"1","name":"DEF"}
    ],
    "images": [
        {"id":"0","name":"PQR"},
        {"id":"1","name":"xyz"}
    ]
};

推荐答案

您可以使用以下代码来完成.您首先使用 dictionary.data 获取数据数组并将其分配给数据变量.之后，您可以使用普通的 for 循环对其进行迭代.每一行都是数组中的一个行对象.

You can do it with the below code. You first get the data array using dictionary.data and assign it to the data variable. After that you can iterate it using a normal for loop. Each row will be a row object in the array.

var data = dictionary.data;

for (var i in data)
{
     var id = data[i].id;
     var name = data[i].name;
}

您可以按照类似的方法迭代图像数组.

You can follow similar approach to iterate the image array.
