How to filter the $scope.Data based on what i click ( Today , Week and Month )

Please help

Answer 1

For filtering the data you can do something along the lines of:

// Set the start and end dates for the search. Limit to one day, week, etc.
const startDate = new Date(2018, 9, 4);
const endDate = new Date(2018, 9, 6);

// Filter by comparing the dates
const filteredData = $scope.Data.filter(e => {
    const date = new Date(e.date);
    return date.getTime() >= startDate.getTime() && date.getTime() <= endDate.getTime();
});

console.log(filteredData);

And bind as applicable to the button clicks.
