Multiple id's in a single JavaScript click event

Question

In JavaScript I am using click event to change chart data. Below is a method for click event.

$(\'#pro1\').click(function () {
            chart.series[0].up         


        

Answer 1

Use a class.

$('.pro').click(function () {
 chart.series[0].update({
   data: $(this).attr('id');
 });
});

And then on each of the #pro1, #pro2, #pro3 elements add a class of 'pro'
