The following is a sample that yields the desired output.
const data = [
{ itemID: '300', status: 'active', inventoryFlag: true, certifiedFlag: false, donateFlag: true },
{ itemID: '400', status: 'inactive', inventoryFlag: true, certifiedFlag: true, donateFlag: false },
{ itemID: '500', status: 'active', inventoryFlag: false, certifiedFlag: false, donateFlag: false },
{ itemID: '600', status: 'active', inventoryFlag: false, certifiedFlag: true, donateFlag: true },
{ itemID: '700', status: 'inactive', inventoryFlag: false, certifiedFlag: true, donateFlag: false }
];
document.getElementById("data").innerText = JSON.stringify(data.filter(o => o.inventoryFlag || o.donateFlag));<textarea id="data" rows="50" cols="100"></textarea>I'm trying to find a way to list the filter-by flags in a separate array and then use that in the .filter() somehow to get the same result set as the above code.
For example, here are the flags to use for filtering AND at least one of the values must be true in the object to be included in the final dataset -
const flags = ['inventoryFlag', 'donateFlag'];
As a start, I tried this but it didn't do anything:
const filteredData = data.filter(o => flags.includes(Object.keys(o)));
Inside of the filter, use the some method to detect if any of the property keys of an entry, that are contained in the flags array, have the a value of true.
const data = [
{ itemID: '300', status: 'active', inventoryFlag: true, certifiedFlag: false, donateFlag: true },
{ itemID: '400', status: 'inactive', inventoryFlag: true, certifiedFlag: true, donateFlag: false },
{ itemID: '500', status: 'active', inventoryFlag: false, certifiedFlag: false, donateFlag: false },
{ itemID: '600', status: 'active', inventoryFlag: false, certifiedFlag: true, donateFlag: true },
{ itemID: '700', status: 'inactive', inventoryFlag: false, certifiedFlag: true, donateFlag: false }
];
const flags = ['inventoryFlag', 'donateFlag'];
const result = data.filter(entry =>
flags.some(flag => entry[flag] === true)
);
console.log(result);
