Filter an array based on an object property

rated 0 times [ 5] [ 1] / answers: 1 / hits: 87656 / 8 Years ago, fri, february 5, 2016, 12:00:00

I have an array of objects, something as follows:

var events = [

  { date: 18-02-2016, name: event A },

  { date: 22-02-2016, name: event B },

  { date: 19-02-2016, name: event C },

  { date: 22-02-2016, name: event D }

];

And I have a date, for example 22-02-2016. How can I get an array with all object which date is the same as the given date? So in this example I would get events B and D.

You could use array's filter() function:

function filter_dates(event) {

    return event.date == 22-02-2016;

}



var filtered = events.filter(filter_dates);

The filter_dates() method can be standalone as in this example to be reused, or it could be inlined as an anonymous method - totally your choice =]

A quick / easy alternative is just a straightforward loop:

var filtered = [];

for (var i = 0; i < events.length; i++) {

    if (events[i].date == 22-02-2016) {

        filtered.push(events[i]);

    }

}
