Question

i have a dynamic data each time there could be dynamically different key value pair to be filtered in different data. how can we filter it with multiple key,value in lodash. i w

Answer 1

You could use plain Javascript and iterate the keys of the filterBy and the values.

var data = [{ VOTER: 1012, PARTY: "REPUBLICAN", PRECINCT: 2408, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 51, BALLOT_STATUS: "PERM" }, { VOTER: 1013, PARTY: "REPUBLICAN", PRECINCT: 2411, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 50, BALLOT_STATUS: "PERM" }, { VOTER: 1014, PARTY: "DEMOCRAT", PRECINCT: 2424, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 50, BALLOT_STATUS: "PERM" }, { VOTER: 1015, PARTY: "DEMOCRAT", PRECINCT: 2418, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 50, BALLOT_STATUS: "POLL" }, { VOTER: 1109, PARTY: "AMERICAN INDEP", PRECINCT: 2404, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 34, BALLOT_STATUS: "POLL" }, { VOTER: 1111, PARTY: "DECLINED", PRECINCT: 2414, AGE_GROUP: "71 +", LAST_VOTED: "08/2006", YEARS_REG: 34, BALLOT_STATUS: "POLL" }],
    filterBy = { PARTY: ["REPUBLICAN", "DEMOCRAT"], BALLOT_STATUS: ["PERM", "POLL"] },
    result = data.filter(function (o) {
        return Object.keys(filterBy).every(function (k) {
            return filterBy[k].some(function (f) {
                return o[k] === f;
            });
        });
    });

console.log(result);

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