Consider the array of objects below,
const resource = [
{
id: 'tony',
shiftday: [
{active: '1', code: 'Sun'},
{active: '1', code: 'Mon'},
{active: '1', code: 'Tue'},
{active: '1', code: 'Wed'},
{active: '1', code: 'Thu'},
{active: '1', code: 'Fri'},
{active: '1', code: 'Sat'},
]
},
{
id: 'alex',
shiftday: [
{active: '0', code: 'Sun'},
{active: '1', code: 'Mon'},
{active: '1', code: 'Tue'},
{active: '0', code: 'Wed'},
{active: '1', code: 'Thu'},
{active: '1', code: 'Fri'},
{active: '0', code: 'Sat'},
]
},
{
id: 'trey',
shiftday: [
{active: '0', code: 'Sun'},
{active: '1', code: 'Mon'},
{active: '0', code: 'Tue'},
{active: '1', code: 'Wed'},
{active: '0', code: 'Thu'},
{active: '1', code: 'Fri'},
{active: '0', code: 'Sat'},
]
},
]
I need to get all values that has active day set to 1 (selected) and match it to the other id's. And to be able to say that which id's have matching active days.
Here is how you can achieve it. I just printed activeDays, instead, you can store it in a separate array, and reuse it after the loop.
const neededArrayOfIds = ['trey']; // <- Declare array of needed IDs
resource.forEach(elm => {
if (neededArrayOfIds.includes(elm.id)) {
const activeDays = elm.shiftday.filter(day => day.active == 1)
console.log(activeDays)
}
})
It give active day array of object.
const activeDays = resource.map(item => item.shiftday.filter(day => day.active === '1'));
console.log(activeDay);
Just use:
const filteredArr = resource.map((item) => {
const filteredShiftDays = item.shiftday.filter((state) = state.active === '1');
return {
id: item.id,
active: filteredShiftDays
};
});
It returns all active days including the ID which days belongs to whom.
