        "url": "http://github.com/nicklockwood/FXForms/"
    }],
    "licensetext": "text"
}],
"isProjectComplete": "true"
};

我可以得到 name、URL 和 license，但不知道如何让 @name 显示在顶部，例如 "Apache License 2.0".

这是当前状态：jsfiddle

Answer 1

使用bracket notation，像这样

console.log(lic['@name']);

Example

Answer 2

如果我没理解错的话，你的问题是你不能在 JS 属性名称中使用像 @ 这样的特殊字符。

只需使用括号：json['@name']
