Question

我正在尝试使用lodash删除标签并仅使用value数组形成一个新数组。我可以知道如何实现吗？

输入：

[
{label: "Campaign 3", value:3}
{label: "Campaign 1", value:1}
{label: "Campaign 4", value:2}
{label: "Campaign 6", value:5}
]

输出：

[3,1,2,5]

Answer 1

您不需要任何第三方插件和库，例如 lodash 和 jquery ，只需将 javascript map 回调函数用作以上在评论部分完成。如果要使用lodash进行相同操作，请按照以下步骤进行操作。

  var input = [
  {label: "Campaign 3", value:3},
  {label: "Campaign 1", value:1},
  {label: "Campaign 4", value:2},
  {label: "Campaign 6", value:5},
];


result = _.map(input, function(o) { return o.value; });

不需要Lodash。您可以使用内置的JavaScript nout:TestEspressoFastlane macbook$ bundle exec fastlane mylane [✔] ?

如何从数组中删除键，并使用javascript只在数组中存储数据？
