Question

我只想使用jquery和javascript使用复选框数组进行过滤。我们的过滤器在组模式下不起作用。如果我们使用多个过滤器，则过滤器将不起作用。您能帮我找到我的错误吗？我想过滤数组。我们的数组的名称是FlyList。我想单击几个复选框。为我们进行多重过滤。

let FlyList = [{
    id: "1",
    Airline_number: "961",
    Type_ticket: "systemi",
    Airline: "dubai",
    fly_time: "04:00-08:00",
    Class_type: "Economical"
  },
  {
    id: "2",
    Airline_number: "962",
    Type_ticket: "charteri",
    Airline: "frans",
    fly_time: "08:00-11:00",
    Class_type: "Commercial"
  },
  {
    id: "3",
    Airline_number: "963",
    Type_ticket: "systemi",
    Airline: "Emirates",
    fly_time: "11:00-14:00",
    Class_type: "Commercial"
  },
  {
    id: "4",
    Airline_number: "964",
    Type_ticket: "systemi",
    Airline: "Emirates",
    fly_time: "14:00-17:00",
    Class_type: "Economical"
  },
  {
    id: "5",

  }
];

function customFilter(list, field, value) {

    let val = e.target.value;
    console.log(field, val);
    customFilter(FlyList, field, val);
  }
}));

function getParents(el, parentSelector /* optional */ ) {

  // If no parentSelector defined will bubble up all the way to *document*
  if (parentSelector === undefined) {
    parentSelector = document;
  }

  var parents = [];
  var p = el.parentNode;

  while (p && (p !== parentSelector || p.parentNode)) {
    var o = p;
    parents.push(o);
    p = o.parentNode;
  }
  parents.push(parentSelector); // Push that parentSelector you wanted to stop at
  return parents;
}

function findFilterTypeElement(element, className) {

Answer 1

在此处不适合使用array.forEach。启用过滤器部分并失败后，该项目将被排除，您需要跳出循环。

这是方法的概述

function isEnabled(filterGroup){
  // todo check DOM for checked
}

function passes(filterGroup, item){
  return filterGroup.items.every(filterItem=>{
     // todo return true if item passes filterItem
  }
}

let itemsFiltered = itemsAll.filter(item=> {
   let pass=true
    for(let filterGroup of filterGroups) {
      if(isEnabled(filterGroup) && !passes(filterGroup, item)) {
          pass=false;
          break;
      }
    }
   return pass;
})

带有选中复选框和多个过滤器的过滤器项目
