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中迭代此对象.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进行操作.您首先使用dictionary.data获取数据数组，并将其分配给data变量.之后，您可以使用普通的for循环对其进行迭代.每行将是数组中的行对象.

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来迭代图像数组.

You can follow similar approach to iterate the image array.
