I have a form with 10 multiple choice questions, the input for each option is a radio button.

Following a few guides and posts from this forum, on form submit I have been able to serialze the values from each selected radio butoon and show the values within a results div. So for example on submit the values "1 2 1 1 4 4 1 1 6 1" might be displayed.

What I'd like to do is just show the most commonly occuring value. (in the above example that would be 1.

Based on links supplied, I've worked out some of what I need to do but am now stuck again!

function showValues() {
    var store = $( ":radio" ).serializeArray(); 
    var frequency = {};  // array of frequency.
    var max = 0;  // holds the max frequency.
    var result;   // holds the max frequency element.
    for(var v in store) {
            frequency[store[v]]=(frequency[store[v]] || 0)+1; // increment frequency.
            if(frequency[store[v]] > max) { // is this frequency > max so far ?
                max = frequency[store[v]];  // update max.
                result = store[v];          // update result.
            }
    }   
    alert(result);
}

returns "Object object" in the alert?

What have I missed?

What do you expect for ties? – A. Wolff Jan 19 '16 at 13:08
Im sorry I dont understand the question? – bigdave Jan 19 '16 at 13:11
I meant if you get "1 2 3", all occurences appearing one time – A. Wolff Jan 19 '16 at 13:12
The event of a tie woud be really unlikely but if it happened then simply displaying the first value that appears most often would be suitable. – bigdave Jan 19 '16 at 13:16

From that link, how would I implement that into my script? – bigdave Jan 19 '16 at 13:32
