织梦网站做好了自定义表单后如何禁用提交按钮?禁用的表单样式怎么写?

如何30秒后可以提交?

经过测试找到了一个*简单的代码

<!DOCTYPE html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>js点击按钮后,倒计时N秒后才能再次点击提交</title>
</head>
<body>
    <input type="button" id="btn" value="免费获取验证码" />
    <script type="text/javascript">
         var wait = 60;
         function time(obj) {
                      if (wait == 0) {
                          obj.removeAttribute("disabled");
                          obj.value = "免费获取验证码";
                          wait = 60;
                      } else {
                          obj.setAttribute("disabled", true);
                          obj.value = "重新发送(" + wait + ")";
                          wait--;
                          setTimeout(function () {
                              time(obj)
                          },
                              1000)
                      }
                  }
         document.getElementById("btn-form1").onclick = function () { time(this); }
    </script>
</body>
</html>
