在这里你去

var e = jQuery.Event("keypress"); 
e.which = 43; // # Some key code value 
$(document).trigger(e);

Answer 2

$(document).on('keypress',function(e) { 
    if (e.keyCode == 43 || e.which == 43) { 
     var identifier = e.target.id; 
     console.log(e.target.id); 
     $('#' + identifier).click(); 
    } 
});
