当键是数字时，jquery访问json

Question

如果这是显而易见的或以前的回答，请原谅我的无知。我有一个像这样的字符串

var test = {"99":{"ttop":"0","lleft":"0","wwidth":"881","hheight":"78"},
"42":{"ttop":"91","lleft":"110","wwidth":"285","hheight":"26"},
"43":{"ttop":"91","lleft":"490","wwidth":"117","hheight":"26"},
"44":{"ttop":"91","lleft":"5","wwidth":"87","hheight":"26"},
"36":{"ttop":"91","lleft":"630","wwidth":"251","hheight":"26"}} 

我已经阅读了很多关于使用文本标识符访问的内容（例如“first-id”而不是“99”）但我认为我的问题是当我使用id作为id时出错。

非常感谢您的帮助

Answer 1

您需要使用bracket notation代替dot notation作为member operator

test['99']

Answer 2

当属性名称不是有效标识符时，请使用数组语法来访问它：

test["99"]
