参考代码：

<!DOCTYPE html><html><head><script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js"></script><script type="text/javascript"> var countdown=60; function settime(obj) {     if (countdown == 0) {         obj.removeAttribute("disabled");            obj.value="免费获取验证码";         countdown = 60;         return;    } else {         obj.setAttribute("disabled", true);         obj.value="重新发送(" + countdown + ")";         countdown--;     } setTimeout(function() {     settime(obj) }    ,1000) }  </script><body> <input type="button" id="btn" value="免费获取验证码" onclick="settime(this)" />   </body></html>

实践例子：
