推荐答案

此方法将更新对象中的所有数字类型自动。

This method will update all numeric types in your objects automatically.

let arr = [{
    "label": "Purok I",
    "y": "1"
  },
  {
    "label": "Purok II",
    "y": "1"
  },
  {
    "label": "Purok III",
    "y": "2",
    "example": "432.23"
  }
];

// Map over your array of objects
arr = arr.map(obj => {
  // Map over all the keys in your object
  Object.keys(obj).map(key => {
    // Check if the key is numeric
    if (!isNaN(obj[key])) {
      obj[key] = +obj[key];
    }
  })
  return obj;
});
console.log(arr);
