javascript - 数组不遍历每个元素

Question

下面是后端的响应:

results = [{
    "name": "FantasticBeasts",
    "count": 546809,
  },

  {
    "name": "SSIPOS",
    "count": 16257,
  },

  {
    "name": "xyz",
    "count": 16257,
  }
]

for (var i = 0; i <= results.length; i++) {
  console.log('result ==>', results[i]);
}

我的最终目标是从数组的每个元素中获取名称。但在此之前，我需要遍历数组元素。但是我无法遍历数组元素。

result ==> undefined

Answer 1

应该是i < results.length因为有 <=您正在比较一个额外的不存在的值。

results = [{
    "name": "FantasticBeasts",
    "count": 546809,
  },

  {
    "name": "SSIPOS",
    "count": 16257,
  },

  {
    "name": "xyz",
    "count": 16257,
  }
]

for (var i = 0; i < results.length; i++) {
  console.log('result ==>', results[i]);
}
