问题：
在用户名的textbox 里按回车键，焦点如何跳转到密码的textbox里？
回复讨论(解决方案)
<script> <br /> var usernameObj = document.getElementById("username"); <br /> usernameObj.onkeydown = function(event) { <br /> e = event ? event :(window.event ? window.event : null); <br /> // 按下回车键且输入框值非空时 <br /> if(e.keyCode==13 && usernameObj.value){ <br /> document.getElementById("password").focus(); <br /> } <br /> } <br /> </script>
