使用JavaScript对象表示法访问json值 [英] Access json value using JavaScript object notation

问题描述

我无法访问json值

{"phone": [
{
    "@attributes": {
        "type": "cell",
        "ext": ""
    }
}, "[phone]", {
    "@attributes": {
        "type": "work",
        "ext": ""
    }
}
]}

使用以下JavaScript：psudo

using the following JavaScript: psudo

for each phone line ...

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

... end for

我预计以下输出：

cell
work [phone]

推荐答案

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

actually your json structure is not perfect, so here is the solution for your desired output

var json = {"phone": [
{
    "@attributes": {
        "type": "cell",
        "ext": ""
    }
}, "[phone]", {
    "@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);
