How to trigger input type button by pressing Enter key

In JSF 1.2 and I'm using h:commandButton type="button" but the button does not trigger when I tab on it and press enter. I tried using onkeypress="keyEnter(event)"

     function keyEnter(eve){
         if (eve.keyCode == 13) {
              document.getElementById(eve.target.id).click();
          }
          return false;
      }

and it triggers the button when enter key is pressed. Now here is my question, I have many h:commandButton elements with type button, what can I do in order to implement keyEnter(eve) to all the elements of type button?

Thanks in advance.

Try this

FULL CODE

function keyEnter(eve){
    var key = eve.keyCode || eve.which;
     if (key == 13) {
         document.getElementById(eve.target.id).click();
     }
      return false;
};

To bind all You can do this

$('input[type="button"]').on("keyenter",function(eve){
     var key = eve.keyCode || eve.which;
     if (key == 13) {
          $(this).click();
      }
      return false;        
});
