JavaScript: 这段代码可以重构为更函数式的编程风格吗？

Question

能否将这段代码链接起来并抽象出 for 循环？使用地图和过滤器？

function listViewFilter(){ // test

  var DateFiltered = containerdata.filter(function (obj){ // remove dates of 010
    return !/010/.test(obj.EventDate); 
  });

  var NameFiltered = [];

  for (var i = 0; i < DateFiltered.length; i++){  // remove EventNames.Name if empty string
    if (DateFiltered[i].EventNames[0].Name == "") continue;
    else NameFiltered.push(DateFiltered[i]);
  }

  Filtered = NameFiltered;
}

Answer 1

当然，您的 for 循环只执行另一个过滤器：

function listViewFilter() {
  var DateFiltered = containerdata.filter(function(obj) { // remove dates of 010
    return !/010/.test(obj.EventDate); 
  });
  var NameFiltered = DateFiltered.filter(function(obj, i) { // remove EventNames.Name if empty string
    return obj.EventNames[0].Name != "";
  });
  Filtered = NameFiltered;
}

或者简而言之

function listViewFilter() {
  Filtered = containerdata.filter(function(obj) {
    return !/010/.test(obj.EventDate) && obj.EventNames[0].Name != "";
  });
}
