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