Question

我一直在搜索stackoverflow问题，试图了解如何通过多个匹配值过滤数组。

我的阵列：

[{"time":"2016-11-30 02:45:00","signal":"Buy","symbol":"AUDNZDecn","price":"1.04605","timeframe":"M15","epoch":"1480473900","candel":"M151480481100"},{"time":"2016-11-30 02:41:00","signal":"Sell","symbol":"AUDJPYecn","price":"84.08700","timeframe":"M1","epoch":"1480473660","candel":"M11480480860"},{"time":"2016-11-30 02:24:59","signal":"Buy","symbol":"EURNZDecn","price":"1.48820","timeframe":"M5","epoch":"1480472699","candel":"M51480479900"}]

您可以看到有3个时间范围：M1，M5，M15

我可以使用以下代码按单个“时间范围”进行过滤：

var j = j.filter(function(el) {
            return el.timeframe == timeframe;
});

注意： j等于来自AJAX查询的JSON解析服务器响应，该查询与php脚本对话，后者传回JSON响应，即上面的数组。

目标：我想要了解的方法是一次过滤数组的多个“时间帧”值，以便当用户点击任意组合的复选框时三个时间帧，我可以从复选框中提取值，并通过用户选择的任意复选框组合过滤数组。恩。 “M1”，“M5”，“M15”，“M1，M5”或M1，M15“或M5，M15”或“M1，M5，M15”等。

返回/过滤的新数组将传递给每个循环的jquery，然后将遍历数据并将数据附加到div。（我已经有了这部分工作）

感谢任何指导！

您可以合并Array.prototype.filter和Array.prototype.some来过滤结果 - 请参阅下面的演示：

＆＃13;

var array = [{"time":"2016-11-30 02:45:00","signal":"Buy","symbol":"AUDNZDecn","price":"1.04605","timeframe":"M15","epoch":"1480473900","candel":"M151480481100"},{"time":"2016-11-30 02:41:00","signal":"Sell","symbol":"AUDJPYecn","price":"84.08700","timeframe":"M1","epoch":"1480473660","candel":"M11480480860"},{"time":"2016-11-30 02:24:59","signal":"Buy","symbol":"EURNZDecn","price":"1.48820","timeframe":"M5","epoch":"1480472699","candel":"M51480479900"}];

function filterResults(arr) {
  return array.filter(function(el) {
    return arr.some(function(e) {
      return el.timeframe == e;
    });
  });
}

// pass the required timeframes to filter here
var result = filterResults(['M1','M5']);

console.log(result);

＆＃13;

.as-console-wrapper{top:0;max-height:100%!important;}
