Question

I have object with bad indexes. I can’t edit this, because i application this working ok.

var object = { "aaa": 1, "aaa": 2, "aaa" : 3, "aaa" : 4};
$.each(object, function(key, value){

});

how can i remove all values where value = 2 and 4?

Answer 1

You can’t. Every value overwrites the previous one in the literal.

$> ({ "aaa": 1, "aaa": 2, "aaa" : 3, "aaa" : 4});
Object
    aaa : 4
$>

You will have to ensure that the object literal is well-formed, then use something like this (ES5) :

var filteredObject = Object.keys( yourObject ).reduce( function ( target, key ) {
    if ( yourObject[ key ] !== 2 && yourObject[ key ] !== 4 )
        target[ key ] = yourObject[ key ];
    return target;
}, { } );
