使用JS将具有匹配键值对的相似对象数组中的值数组组合在一起

function combineValues(objArray) {
  var combinedObj = {};

  objArray.forEach(function(obj) {
    var key = Object.keys(obj)[0];
    var value = obj[key];

    if (combinedObj.hasOwnProperty(key)) {
      combinedObj[key].push(value);
    } else {
      combinedObj[key] = [value];
    }
  });

  return Object.entries(combinedObj);
}

// 示例用法
var objArray = [
  { key1: 'value1' },
  { key2: 'value2' },
  { key1: 'value3' },
  { key3: 'value4' },
  { key2: 'value5' }
];

var combinedArray = combineValues(objArray);
console.log(combinedArray);

[
  ['key1', ['value1', 'value3']],
  ['key2', ['value2', 'value5']],
  ['key3', ['value4']]
]
