javascript - 使用 JavaScript 对象表示法访问 json 值

Question

我无法访问 json 值

{"phone": [
{
    "@attributes": {
        "type": "cell",
        "ext": ""
    }
}, "(123) 456 7890", {
    "@attributes": {
        "type": "work",
        "ext": ""
    }
}
]}

使用以下 JavaScript:psudo

for each phone line ...

console.log(["@attributes"].type);
console.log(this); 
console.log(["@attributes"].ext);

... end for

我期望以下输出:

cell
work (123) 456 7890

Answer 1

实际上你的json结构并不完美，所以这里是你想要的输出的解决方案

var json = {"phone": [
{
    "@attributes": {
        "type": "cell",
        "ext": ""
    }
}, "(123) 456 7890", {
    "@attributes": {
        "type": "work",
        "ext": ""
    }
}
]};
 console.log(json['phone'][0]['@attributes'].type);
 console.log('<br/>'+json['phone'][1]);
 console.log('<br/>'+json['phone'][2]['@attributes'].type);
