Question

$("#action_button").click(function() {

How would I bind an onEnter event with a different selector to the same code above?

Answer 1

move the logic to a common method and call that from everywhere.for onenter event,bind keyup and check for keycode 13.

$("#new_selector").keyup(function(event){
    var keyCode = event.keyCode || event.which; // browser compatible
    if(keyCode === 13){
        do_something();
    }
});

$("#action_button").click(function() {
   do_something();
});

function do_something(){
//
}
