Javascript “如何隐藏”一词；提交；一旦表单成功发送，是否单击按钮？

当表单成功发送时，我想隐藏表单的“提交”按钮。我试图添加

$（'#submit'）.hide（2000）紧跟在
$（'.success'）.fadeIn（1000）之后
但是没有成功。
谢谢

HTML:

启动ajax成功函数时，隐藏按钮

$this.find('input:submit').hide();

你的代码变成了

$(document).ready(function () {
    $("#contactfrm").submit(function (e) {
        var $this =$(this);//added this code here
        e.preventDefault();
        var name = $("#name").val();
        var email = $("#email").val();
        var message = $("#message").val();
        var dataString = 'name=' + name + '&email=' + email + '&message=' + message;

        function isValidEmail(emailAddress) {
            var pattern = new RegExp(/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i);
            return pattern.test(emailAddress);
        };

        if (isValidEmail(email) && (message.length > 10) && (name.length > 1)) {
            $.ajax({
                type: "POST",
                url: "sendmessage.php",
                data: dataString,
                success: function () {
                    $('.success').fadeIn(1000);
                    $this.find('input:submit').hide();//added this code here
                }
            });
        } else {
            $('.error').fadeIn(1000);
        }

        return false;
    });
});

试试这个：

success: function(){
      $('.success').fadeIn(1000);
      $('input[name="submit"]').hide();
    }

但我建议您将提交的html更改为：

<input type="submit" value="Envoyer" name="submit" id="submit">

改变

  <input type="submit" value="Envoyer" name="submit">



到

这将隐藏页面上的所有提交按钮。
<input type="submit" value="Envoyer" name="submit" id="submit">

success: function(){
          $('.success').fadeIn(1000);
          $('#submit').hide();
        }

  <input type="submit" value="Envoyer" name="submit">

    <input type="submit" value="Envoyer"  id="submit" name="submit">
