In javascript a map is acutally pretty much the same as a classical object:
在javascript中，map与经典的对象非常相似:
{ "1": "aaa", "2":"bbb","3":"ccc",... }
I am not 100% sure you can use numbers as keys...
我不能百分之百地肯定你能把数字当作钥匙……
an alternative would be to use a structure like this and have an array of objects:
另一种选择是使用这样的结构并拥有一系列对象:
[ {id:1,text:"aaa"},{id:2,text:"bbb"},{id:3,text:"ccc"},... ]
or to be more in the spirit of a map, you should name the fields "map-like":
或者更符合地图的精神，你应该把这些字段命名为“类似地图”:
[ {key:1,value:"aaa"},{key:2,value:"bbb"},{key:3,value:"ccc"},... ]
All 3 are valid json/javascript forms, which one suits you best depends on what you actually want to use it for.
这3种都是有效的json/javascript表单，哪个最适合您，取决于您实际想要使用它做什么。
