在jquery中，可以通过如下的方法，检测是否按下了回车键
$('#someTextBox').keypress(function(event){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == ''){
alert('You pressed a "enter" key in textbox');
}
});
$(document).keypress(function(event){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == ''){
alert('You pressed a "enter" key in somewhere');
}
});
注意，firefox是支持 event.which去获得键的ascii码，而ie是同时支持
event.keyCode和 event.which的
