Parsing JSON w/ @ at sign symbol in it (arobase)
提问by user823596
My JSON object evaluates to:
我的 JSON 对象评估为：
{ "@io": IO, "@type": XXX }
If this variable is called my_json, how do I access the @typevalue of XXX? I tried my_json.@type, but this is giving errors. Help appreciated. Thanks,
如果调用此变量my_json，我如何访问@typeXXX的值？我试过my_json.@type，但这是给出错误。帮助表示赞赏。谢谢，

Use square bracket notation with a string:
对字符串使用方括号表示法：
var XXXValue = my_json['@type'];
The same can be used when you have a property name in a variable. Using your same example:
当变量中有属性名称时，也可以使用相同的方法。使用相同的示例：
var propertyName = '@type';
var XXXValue = my_json[propertyName];

As you've discovered, you can't use an @ symbol in a Javascript variable name, my_json.@typeis invalid.
正如您所发现的，您不能在 Javascript 变量名称中使用 @ 符号，这my_json.@type是无效的。
The good news for you is that you can access your variables as array subscripts. You would do it like this:
对您来说好消息是您可以将变量作为数组下标访问。你会这样做：
my_json["@type"]
Hope that helps.
希望有帮助。

If it ends up evaluating you can take the object and probably grab it by the key.
如果它最终评估你可以拿走对象并可能通过钥匙抓住它。
ie obj["@type"]. But something does seem a bit off.
即 obj["@type"]。但似乎有些不对劲。
