如何在javascript中过滤具有多个条件的数组？

Question

So my example array as follows,

{
    "available": [
        {
            "AC": "false",
            "availableSeats": "18",
            "avlWindowSeats": "10",
            "bookable": "true",
            "nonAC": "true",
            "seater": "false",
            "sleeper": "true",
            "zeroCancellationTime": "0",
            "mTicketEnabled": "true"
        },
        {
            "AC": "false",
            "availableSeats": "18",
            "avlWindowSeats": "10",
            "bookable": "true",
            "nonAC": "true",
            "seater": "true",
            "sleeper": "true",
            "zeroCancellationTime": "0",
            "mTicketEnabled": "true"
        },
        ....
    ]
}

And my filter data as follows,

var filters = {
            nonAC: [
                "true"
            ],
            seater: [
                "true"
            ],
            sleeper: [
                "true"
            ],
        };

And i have created a query builder which helps to finalize the query !

buildFilter = (filter) => {
        let query = {};
        for (let keys in filter) {
            if ( (filter[keys].constructor === Object) || (filter[keys].constructor === Array && filter[keys].length > 0)) {
                query[keys] = filter[keys];
            }
        }
        return query;
    };

And finally my filter function as follows,

filterData = (data, query) => {
        const filteredData = data.filter( (item) => {
            for (let key in query) {
                if (item[key] === undefined || !query[key].includes(item[key])) {
                    return false;
                }
            }
            return true;
        });
        return filteredData;
    };

If you notice my filter conditions it says

seater: [
                "true"
            ],
            sleeper: [
                "true"
            ],

Which obliviously means that if seater and sleeper is true then filter that, but the problem is i need the result as "seater or sleeper" so, if any one is true it should filter that,

So how to change my filter function which accepts as seater or sleeper.

The result should give both the array as result not the second one alone as output !

Answer 1

You coiuld get the entries of filters and filter if one of the filter is true .

 const available = [{ AC: "false", availableSeats: "18", avlWindowSeats: "10", bookable: "true", nonAC: "true", seater: "false", sleeper: "true", zeroCancellationTime: "0", mTicketEnabled: "true" }, { AC: "false", availableSeats: "18", avlWindowSeats: "10", bookable: "true", nonAC: "true", seater: "true", sleeper: "true", zeroCancellationTime: "0", mTicketEnabled: "true" }], filters = { nonAC: ["true"], seater: ["true"], sleeper: ["true"] }, filterEntries = Object.entries(filters), result = available.filter(object => filterEntries.some(([key, values]) => values.includes(object[key])) ); console.log(result);
