无法读取属性＆＃39;长度＆＃39;未定义的Uncaught TypeError：？

Question

我正在尝试打印y中的对象名称有其键值但是出错。 请帮帮我......

这是我的java脚本代码

this.data

Answer 1

var object = {
name: "venu",
id: 99,
age: 100,
"x": [
    "balaji",
    22,
    11
],
/*>>>not inside the x>>>*/ "y": {
    name: "balu",
    id: 55,
    age: 22
}
};

var g = object.x;
for (var i = 0; i < g.length; i++) {
for (var k = 0; k < g[i].y.length; k++) { //object.x.y.length is undefined as y is not something in x
    console.log(g[i].y.name);
}
}
