jquery how to catch enter key and change event to tab

Here is a solution :

$('input').on("keypress", function(e) {
            /* ENTER PRESSED*/
            if (e.keyCode == 13) {
                /* FOCUS ELEMENT */
                var inputs = $(this).parents("form").eq(0).find(":input");
                var idx = inputs.index(this);

                if (idx == inputs.length - 1) {
                    inputs[0].select()
                } else {
                    inputs[idx + 1].focus(); //  handles submit buttons
                    inputs[idx + 1].select();
                }
                return false;
            }
        });

Why not something simple like this?

$(document).on('keypress', 'input', function(e) {

  if(e.keyCode == 13 && e.target.type !== 'submit') {
    e.preventDefault();
    return $(e.target).blur().focus();
  }

});

This way, you don't trigger the submit unless you're focused on the input type of "submit" already, and it puts you right where you left off. This also makes it work for inputs which are dynamically added to the page.

Note: The blur() is in front of the focus() for anyone who might have any "on blur" event listeners. It is not necessary for the process to work.

This works perfect!

 $('input').keydown( function(e) {
        var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
        if(key == 13) {
            e.preventDefault();
            var inputs = $(this).closest('form').find(':input:visible');
            inputs.eq( inputs.index(this)+ 1 ).focus();
        }
    });
