在Javascript / AngularJS中获取HashMap的Key和Value(get Key and Value of HashMap in Javascript/AngularJS)

在Javascript / AngularJS中获取HashMap的Key和Value(get Key and Value of HashMap in Javascript/AngularJS)

我在前端有这个HashMap从后端获取：

var myVar = {"24":{"amount":2,"minutes":30},"32":{"amount":3,"minutes":30}}

有谁知道我可以如何获得JavaScript / AngularJS中的键和值？ 我努力了

{{myVar.24}} {{myVar.next()}}

但没有任何工作。

I have this HashMap in Frontend getting from Backend:

var myVar = {"24":{"amount":2,"minutes":30},"32":{"amount":3,"minutes":30}}

Does anyone know how I can get the keys and the values in Javascript/AngularJS? I have tried

{{myVar.24}} {{myVar.next()}}

but nothing works.

这是javascript中的一个对象，在这里你使用数字字符串作为关键字，以便使用此语法访问对象值myVar [key] ; 看下面的例子

var myVar = {"24":{"amount":2,"minutes":30},"32":{"amount":3,"minutes":30}}
console.log(myVar['24']); 
  
 
This is an object in javascript and here you use number string as a key so to access the object values use this syntax myVar[key] ; look at the example below 
 
 
 
  
  
var myVar = {"24":{"amount":2,"minutes":30},"32":{"amount":3,"minutes":30}}
console.log(myVar['24']);
