Topic: Finding number of options selected in multiple choice

Hi i want to know how we can find out number options selected in multiple choice button.

Multiple-choice button as in a set of checkboxes? Or as in a SELECT element that allows multiple selections?

and you didn't think that this was a sloved problem and the solution was already all over the interNets ?

I assume you are talking about SELECT item (you mentioned "options")

function countSelectedItems(id){
              var opts=document.getElementById(id).options;
              var ret=0;
              for(var i=0;i<opts.length;i++) 
                  ret+=(opts[i].selected)?1:0;
              return ret;
          }
