I have array of object and object in which have to
check the arrobj code and obj value are same,
if above condition ok, then check the obj idtype and arrobj code
is same or obj.idtype value exists then return array list or return []
of object in javascript
var arrobj = [
{id:1, code: "brown", type: "FR"},
{id:3, code: "black", type: "SP"},
{id:4, code: "blue", type: "FR"}
]
var obj={
id:20, idtype: "SG", value: "blue"
}
Expected Output
// arrobj.code and obj.value matches, obj.idtype and arraobj.type not same
[]
var arrobj2 = [
{id:1, code: "brown", type: "FR"},
{id:3, code: "green", type: "SP"},
{id:4, code: "blue", type: "FR"},
{id:5, code: "blue", type: "SG"}
]
var obj2={
id:20, idtype: "SG", value: "blue"
}
Expected Output
// arrobj.code and obj.value matches, obj.idtype value exists in arraobj.type
[
{id:4, code: "blue", type: "FR"},
{id:5, code: "blue", type: "SG"}
]
If you want to filter a javascript object array (code: equal and type: non equal) you can use the filter method.
const sampleCars1 = [
{id: 1, code: "brown", type: "FR"},
{id: 2, code: "black", type: "SP"},
{id: 3, code: "green", type: "Y1"},
{id: 4, code: "blue", type: "FR"}
];
const sampleCars2 = [
{id: 1, code: "brown", type: "FR"},
{id: 2, code: "black", type: "X1"},
{id: 3, code: "green", type: "SP"},
{id: 4, code: "blue", type: "FR"},
{id: 5, code: "blue", type: "SG"},
{id: 6, code: "blue", type: "A1"},
{id: 7, code: "blue", type: "A2"}
];
const filterCars = (cars, desiredCode, undesiredType) => {
return cars.filter(item =>
item.code === desiredCode && item.type !== undesiredType);
}
const filterSampleLists = () => {
const filter = {id:20, type: "SG", code: "blue"};
const filteredSample1 = filterCars(sampleCars1, filter.code, filter.type);
const filteredSample2 = filterCars(sampleCars2, filter.code, filter.type);
console.log(filteredSample1);
console.log(filteredSample2);
}
