How to access json object key with space
提问by user3210416
I have a json file and the key of almost each object has a space between them, for their first and last name. So every time I try and call the value of that key it says 'undefined. How do I get the values to show?
我有一个 json 文件，几乎每个对象的键之间都有一个空格，用于他们的名字和姓氏。因此，每次我尝试调用该键的值时，它都会显示“未定义”。我如何获得要显示的值？
