     使用示例:

    $("input[id='search_key']").bind("keypress", function () {
         if(event.keyCode==13)
          {
                   $("#search").click();
           }                                       
    });
    

    onkeypress 事件在用户按下并放开任何字母数字键时发生。但是系统按钮(例如:箭头键、功能键)无法得到识别。
    onkeydown 事件在用户按下任何键盘键(包括系统按钮)时发生。
    具体区别
    1. 一个放开一个没有放开,onkeydown 先于 onkeypress 发生。
    2.onkeypress 无法系统按钮。
    2.onkeydown 捕获的 keyCode 不区分字母大小,而 onkeypress 区分。
