I am working with a JavaScript array that looks like this:
{id: 'ZM', name: "Zambia"},
{id: 'MZ', name: "Mozambique"},
{id: 'BW', name: "Botswana"},
{id: 'NA', name: "Namibia"},
{id: 'MW', name: "Malawi"},
{id: 'ZW', name: "Zimbabwe"},
I need to fetch specific array records based on the ids ('BW', 'MW'). How can I achieve this? For example, after fetching, I want the array records to be as follows:
{id: 'BW', name: "Botswana"},
{id: 'MW', name: "Malawi"}
If you're looking for a similar solution, here's an example:
function retrieve(array, identifiers) {
return array.filter(function (element) {return identifiers.indexOf(element.id) !== -1;});
}
This function will filter the array to only include objects with IDs that match those in the identifiers array. You can use it like this:
var countries = [ {id: 'ZM', name: "Zambia"},
{id: 'MZ', name: "Mozambique"},
{id: 'BW', name: "Botswana"},
{id: 'NA', name: "Namibia"},
{id: 'MW', name: "Malawi"},
{id: 'ZW', name: "Zimbabwe"}];
function retrieve(array, identifiers) {
return array.filter(function (element) {return identifiers.indexOf(element.id) !== -1;});
}
retrieve(countries, ["BW", "MW"]);//Result: [{id: 'BW', name: "Botswana"},{id: 'MW', name: "Malawi"}]
