Question

除了偶尔的jQuery选择器和元素修改之外，我在javascript上也不是很好。对于我遇到的问题，我需要按日期过滤掉一个javascript对象。我的结构看起来像这样：

Object { version: "3.1.1", released_on: "2016-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 }

我希望在"2016-08-21T00:00:00.000Z"和"2010-08-21T00:00:00.000Z"之间找到10年以来的所有对象。我遇到的问题是released_on:字段是字符串而不是日期。我是否需要创建一个new Date()对象将其转换为字符串，然后使用.filter或者我会相反，将字符串转换为日期然后过滤。有人曾尝试过这样的事吗？

您可以执行以下操作;

var data = [{ version: "3.1.1", released_on: "2016-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2011-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2009-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2006-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2013-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2017-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
            { version: "3.1.1", released_on: "2015-08-21T00:00:00.000Z", high_vulns: 15, medium_vulns: 10, low_vulns: 5 },
           ],
      ed = new Date("2016-08-21T00:00:00.000Z").getTime(),
      sd = new Date("2010-08-21T00:00:00.000Z").getTime(),
  result = data.filter(d => {var time = new Date(d.released_on).getTime();
                             return (sd < time && time < ed);
                            });
console.log(result);

如何在两个日期之间过滤对象数组？
