Question

I'm working with google charts using angularJs. The problem am facing is that the data used in the chart must be an array but the type of data I have is an object. So how can I convert it to an array. The data I have :

Object {Normale: 1129, urgente: 153}

The array am trying to have would be something like this:

[['priorite', 'nb'], ['urgente', 1129],['normale', 153]]

Thank you,

Answer 1

var myArray = [];
angular.forEach(function(obj) {
    myArray.push({"priorite": obj.Normale, "nb": obj.urgente});
});

Answer 2

You can use reduce on the Object.keys:

var o = {
  Normale: 1129,
  urgente: 153
};

var a = Object.keys(o).reduce((a, b) => a.concat({
  priorite: b,
  nb: o[b]
}), []);

console.log(a);

Answer 3

Lodash很容易做到这一点。

使用toPairs方法将对象转换为对
使用Array.unshift方法在第一个位置插入['priorite', 'nb']
这就是全部！ ;）

＆＃13;

var obj = {Normale: 1129, urgente: 153};
var arr = _.toPairs(obj);
arr.unshift(['priorite', 'nb']);

console.log(arr);

您也可以通过这些方式按其价值（首先是紧急，最后是非常低）订购优先顺序：

＆＃13;

var obj = {VeryLow: 100, Normal: 500, Urgent: 1000, Low: 250};
var arr = _.toPairs(obj);
arr = arr.sort(function compare(a, b) {
  if (a[1] > b[1])
     return -1;
  if (a[1] < b[1])
     return 1;
  return 0;
});
arr.unshift(['priorite', 'nb']);

console.log(arr);
