Filter array of multiple value-CodePudding

This is my issue, I try to get result of items base on my filter array.

const papaFilter=[
{type:'event', value: ['In Person']},
{type:'city', value: ['Boston', 'Miami', 'New York']}
]

const items = [
{city: 'Boston', type: 'In Person'},
{city: 'New Jersey', type: 'In Person'},
{city:'Boston', type:'Virtual'}
]

const filteredResults = items.filter(el => papaFilter.some(filterEl => el[filterEl.type] === filterEl.value));

I want the first object of my items because papafilter contain Boston and In Person.

I know in my condition filterEl.value is an array of multiple value so this condition doesn't work. Any Ideas?

CodePudding user response：

You could filter the array by iteratirn the entries of the object and the filter array.

This approach takes an object for replacing keys.

const
    replacements = { type: 'event' },
    filter = [{ type: 'event', value: ['In Person'] }, { type: 'city', value: ['Boston', 'Miami', 'New York'] }],
    items = [{ city: 'Boston', type: 'In Person' }, { city: 'New Jersey', type: 'In Person' }, { city: 'Boston', type: 'Virtual' }],
    result = items.filter(o => Object.entries(o).every(([k, v]) =>
        filter.some(({ type, value }) => type === (replacements[k] || k) && value.includes(v))
    ));

console.log(result);

I think you are looking for Array.includes. So, filterEl.value.includes(el[filterEl.type]) in the last block should give you the desired result.
