读取数组中每个对象的所有键值对

// 假设数组名为data
var data = [
  { name: 'Alice', age: 25, gender: 'female' },
  { name: 'Bob', age: 30, gender: 'male' },
  { name: 'Charlie', age: 35, gender: 'male' }
];

// 遍历数组
for (var i = 0; i < data.length; i++) {
  var obj = data[i];
  
  // 遍历对象的键值对
  for (var key in obj) {
    var value = obj[key];
    console.log(key + ': ' + value);
  }
}

name: Alice
age: 25
gender: female
name: Bob
age: 30
