Question

I have a javascript object like the following:

var Numeric_values = {
US:  {01: "202-555-0151", 02: "202-555-0167", 03: "202-555-0150"},
CAD: {01: "613-555-0144", 02: "613-555-0192", 03:"613-555-0151"},
AUS: {01: "1900 654 321"}
};

I am attempting to access all of the values of this object and listing them out as a string like this:

"202-555-0151","202-555-0167", "202-555-0150"
"613-555-0144", "613-555-0192","613-555-0151"
"1900 654 321"

I have so far attempted to use Object.values(Numeric_Values) and

for (let key in Numeric_values){
      console.log(Numeric_values[key]);
  }

and these always return as [object,object], how can i fix this?

您可以通过Object.values和Array.forEach打印/访问它们：

var data = {
  US: {
    01: "202-555-0151",
    02: "202-555-0167",
    03: "202-555-0150"
  },
  CAD: {
    01: "613-555-0144",
    02: "613-555-0192",
    03: "613-555-0151"
  },
  AUS: {
    01: "1900 654 321"
  }
};

Object.values(data).forEach(x => console.log(...Object.values(x)))

您还可以递归地获取如下值：

var data = {
  US: {
    01: "202-555-0151",
    02: "202-555-0167",
    03: "202-555-0150"
  },
  CAD: {
    01: "613-555-0144",
    02: "613-555-0192",
    03: "613-555-0151"
  },
  AUS: {
    01: "1900 654 321"
  }
};

const flatten = (obj, a = []) => Object.values(obj)
  .reduce((r, c) => (typeof c == 'object' ? flatten(c, a) : r.push(c), r), a)

console.log(...flatten(data))

Javascript object values returning as [object,object]
