Question

我正在尝试使用for循环将数据添加到json对象中，但push方法无效，因为它将对象添加到json数组中，是否有想法将数据添加到json对象中？

我的代码：

    var data = [
        { Name: "Jake", Gender: "Male", Address: "Address1" },
        { Name: "Laura", Gender: "Female", Address: "Address2" },
    ];

    for (var i = 0; i < data.length; i++) {
        if (data[i].Gender == "Male") {
            data[i].push({ Icon: "image/male.png" });
        } else {
            data[i].push({ Icon: "image/female.png" });
        }
    }

    var result = data;

我需要结果为：

result = [
            { Name: "Jake", Gender: "Male", Address: "Address1", Icon: "image/male.png" },
            { Name: "Laura", Gender: "Female", Address: "Address2", Icon: "image/female.png" },
        ];

将根据if条件

在每个对象中添加数据Icon

Answer 1

只有一个Icon，因此您可以直接设置它：

for (var i = 0; i < data.length; i++) {
    if (data[i].Gender == "Male") {
        data[i].Icon = "image/male.png";
    } else {
        data[i].Icon = "image/female.png";
    }
}

之前，您应该在控制台中看到错误，因为data[i]是一个对象（不是数组）并且没有任何方法push

Answer 2

以下是您需要做的事情：

var data = [
        { Name: "Jake", Gender: "Male", Address: "Address1" },
        { Name: "Laura", Gender: "Female", Address: "Address2" },
    ];
    for (var i = 0; i < data.length; i++) {
        if (data[i].Gender == "Male") {
            data[i].Icon = "image/male.png";

        } else {
            data[i].Icon = "image/female.png";
        }
    }

    var result = data;
    alert(result[0].Icon);
    alert(result[1].Icon);
