推荐答案

首先，您的对象中没有名为97433的键

Firstly, there is no key named 97433 in your object

第二，即使您不能使用带有数字开头的对象键的属性修饰符.您需要使用方括号表示法.

Secondly, even if there was you cannot use property accesors with object keys which begin with a number. You need to use bracket notation.

最后，使用console.log()进行调试，因为alert()强制类型并阻止UI逻辑.

Lastly, use console.log() for debugging as alert() coerces types and blocks the UI logic.

var myVariable = obj['97433'];
console.log(myVariable);
