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]);
}
}
event.date == "..." conditional would need to change to event.date.includes('2016') (alternatively, you could also use .indexOf('2016'))User Array.prototype.filter() as follows:.
var filteredEvents = events.filter(function(event){
return event.date == '22-02-2016';
});
array filter
