<p>I obtained the following objects using AJAX and stored them in an array: </p> <pre class="brush:php;toolbar:false;">var homes = [ { "h_id": "3", "city": "Dallas", "state": "Texas", "zip": "75201", "price": "162500" }, { "h_id": "4", "city": "Beverly Hills", "state": "California", "zip": "90210", "price": "319250" }, { "h_id": "5", "city": "New York", "state": "New York State", "zip": "00010", "price": "962500" } ];</pre> <p>How can I create a function using JavaScript that sorts objects in ascending<strong> or </strong>descending order using only the <code>price</code> property? </p>

const sort_by = (field, reverse, primer) => {

  const key = primer ?
    function(x) {
      return primer(x[field])
    } :
    function(x) {
      return x[field]
    };

  reverse = !reverse ? 1 : -1;

  return function(a, b) {
    return a = key(a), b = key(b), reverse * ((a > b) - (b > a));
  }
}


//现在您可以按任何字段排序...

const homes=[{h_id:"3",city:"Dallas",state:"TX",zip:"75201",price:"162500"},{h_id:"4",city:"Bevery Hills",state:"CA",zip:"90210",price:"319250"},{h_id:"5",city:"New York",state:"NY",zip:"00010",price:"962500"}];

// 按价格从高到低排序
console.log(homes.sort(sort_by('price', true, parseInt)));

// 按城市排序，不区分大小写，按A-Z排序
console.log(homes.sort(sort_by('city', false, (a) =>  a.toUpperCase()
)));

homes.sort(function(a, b) {
    return parseFloat(a.price) - parseFloat(b.price);
});

homes.sort((a, b) => parseFloat(a.price) - parseFloat(b.price));

homes.sort((a, b) => parseFloat(b.price) - parseFloat(a.price));
