I am new to JS. I want to apply filter on array based on other arrays. For example : Filter data
array based on property names from colNames
and values from Values
array. The colNames
and Values
arrays can have any length (not always 2).
var data = [{ "name": "Tiger Nixon", "position": "System Architect", "salary": "320800", "start_date": "2011/04/25", "office": "Edinburgh", "rating": "5421" }, { "name": "Garrett Winters", "position": "Accountant", "salary": "170750", "start_date": "2011/07/25", "office": "Tokyo", "rating": "8422" }, { "name": "Garrett Winters", "position": "Analyst", "salary": "170750", "start_date": "2011/07/25", "office": "Tokyo", "rating": "8422" }, { "name": "Ashton Cox", "position": "Junior Technical Author", "salary": "86000", "start_date": "2009/01/12", "office": "San Francisco", "rating": "1562" }, { "name": "Cedric Kelly", "position": "Senior Javascript Developer", "salary": "433060", "start_date": "2012/03/29", "office": "Edinburgh", "rating": "6224" } ] var colNames = ['name', 'position'] var Values = ['Garrett Winters', 'Accountant']
Expected Outcome
[{ "name": "Garrett Winters", "position": "Accountant", "salary": "170750", "start_date": "2011/07/25", "office": "Tokyo", "rating": "8422" }]

Answer
You could filter with the iteration of all keys and check with the values.
const data = [{ name: "Tiger Nixon", position: "System Architect", salary: "320800", start_date: "2011\/04\/25", office: "Edinburgh", rating: "5421" }, { name: "Garrett Winters", position: "Accountant", salary: "170750", start_date: "2011\/07\/25", office: "Tokyo", rating: "8422" }, { name: "Garrett Winters", position: "Analyst", salary: "170750", start_date: "2011\/07\/25", office: "Tokyo", rating: "8422" }, { name: "Ashton Cox", position: "Junior Technical Author", salary: "86000", start_date: "2009\/01\/12", office: "San Francisco", rating: "1562" }, { name: "Cedric Kelly", position: "Senior Javascript Developer", salary: "433060", start_date: "2012\/03\/29", office: "Edinburgh", rating: "6224" }], cols = ['name', 'position'], values = ['Garrett Winters', 'Accountant'], result = data.filter(o => cols.every((k, i) => o[k] === values[i])); console.log(result);
