经常用到的一个功能，当我们输入完账号密码后直接按回车进入下个页面，比拿起鼠标再去点击“登录”略显人性化 做的一个测试页，代码： <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www./TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www./1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>测试</title> <script type="text/javascript"> function on_return() { if(window.event.keyCode == 13) //13,代表回车按键 { if (document.all('sub')!=null){ document.all('sub').click(); } } } function check() { var user = document.getElementById("user").value; var pwd = document.getElementById("pwd").value; if(user == 'aa' && pwd == 'bb') { alert("success"); } } </script> </head> <body onkeydown="on_return();"> <form> <input type="text" name="username" id="user" />username <br /> <input type="text" name="pass" id="pwd" />password <br /> <input type="submit" id="sub" value="sub" onClick='check()' /> </form> </body> </html> |
