看起来您发布了 php。

无论如何，看看sort功能:

var numbers = [{
  age: 10,
  salary: {
    gbp: 10,
    eur: 0,
    usd: 0
  }
}, {
  age: 2,
  salary: {
    gbp: 0,
    eur: 345,
    usd: 0
  }
}, {
  age: 100,
  salary: {
    gbp: 0,
    eur: 0,
    usd: 23
  }
}, {
  age: 50,
  salary: {
    gbp: 0,
    eur: 432,
    usd: 0
  }
}];

numbers.sort(function(a, b) {
  // Get the sum of salaries in the a object
  let aAmt = Object.values(a.salary).reduce((s, v) => s + v, 0)
  // Get the sum of salaries in the b object
  let bAmt = Object.values(b.salary).reduce((s, v) => s + v, 0)
  // Calculate the difference
  return bAmt - aAmt
})

console.log(numbers);
