通过键值从数组中查找和删除对象

Question

This is very similar to existing threads but not quite the same:

Find object by id in an array of JavaScript objects

From this thread I know that I can find an Object via $.grep :

var events = [
                {startTime: 5, endTime: 20}, 
                {startTime: 15, endTime: 22}, 
                {startTime: 30, endTime: 31}
             ];

var results = $.grep(events, function(e){ 
   return (e.startTime == 15 && e.endTime == 22); });
return results[0]; // 1 result guaranteed

But how would I remove this found object from the events array? In order to use splice , do I need an index along with $.grep ?

I need to find the Object in the Array by Key/Value, and then remove it.

 var events = [ {startTime: 5, endTime: 20}, {startTime: 15, endTime: 22}, {startTime: 30, endTime: 31} ]; var results = $.grep(events, function(e){ return (e.startTime == 15 && e.endTime == 22); }); console.log(results[0]); //console.log(events); // 1 result guaranteed

Answer 1

var events = [
    {startTime: 5, endTime: 20}, 
    {startTime: 15, endTime: 22}, 
    {startTime: 30, endTime: 31}
];

var filteredEvents = events.filter(function(item) {
    return item.prop !== undersirableValue;
});

Answer 2

Just use filter and negate the search

 var events = [{ startTime: 5, endTime: 20 }, { startTime: 15, endTime: 22 }, { startTime: 30, endTime: 31 } ]; events = events.filter(e => !(e.startTime == 15 && e.endTime == 22)); console.log(events);
