Question

I’m trying to build a questionnaire / personality test with jQuery.
I have an object in the end :

results = {
quality1 : 2,
quality2 : 3,
quality3 : 0,
quality4 : 3,
etc
}

I then want to retrieve the key with the higher value. No problem if there is only one matching result :

    topScore = 0;
    $.each(results, function(i,val) {
    if ( results[i] > topScore ) {
        topScore = results[i];
        topQuality = i;
    }
});
    console.log('Higher quality : ' + topQuality)

but what if there are many ? (for instance, in the example, quality2 and quality4)

I’m kind of lost, here…

Answer 1

topScore = 0;
var topQualityIndexes = [];
$.each(results, function(i,val) {
   if ( results[i] > topScore ) {
    topScore = results[i];
    topQualityIndexes = [i];     
   }else if( results[i] == topScore ){
    topQualityIndexes.push(i);
   }
});
//Printing 
console.log( 'Higher qualities: ' + topQualityIndexes.join(",") );
