how to combine jquery commands?

Question

I have code like this

    $(document).on('click', '.addtocart .plus, .addtocart .minus', function () {
        var num = $('a.account span').text();
        .........
            .........
     });

Same code applies for

$(document).on('change','.addtocart .qty', function () {
        var num = $('a.account span').text();
        .........
            .........
 });

Can anyone tell me how to combine these click and change events?

Finally figure out it was the if/else?? check in your deleted question? — epascarello

The simplest solution is to define a function

function f() {
     var num = $('a.account span').text();
     ...
}
$(document).on('click', '.addtocart .plus, .addtocart .minus', f)
.on('change','.addtocart .qty', f);

If you don't want to pollute the external namespace with this additional function, you may use an IIFE :

(function(){
  function f() {
     var num = $('a.account span').text();
     ...
  }
  $(document).on('click', '.addtocart .plus, .addtocart .minus', f)
  .on('change','.addtocart .qty', f);
})();
