Question

我正在使用此帖子在点击时禁用我的按钮：

Prevent multiple form submits in MVC 3 with validation

这是我渲染后的页面来源：

<!DOCTYPE html>

<html>
  <head>


    <title>Do not bookmark this page.</title>
    <link href="/Content/reset.css" rel="stylesheet" type="text/css" />

    <script language="javascript" type="text/javascript">
      $(function () {
        $('form').submit(function () {
          if ($(this).valid()) {
            $('input[type="submit"]').attr('disabled', 'disabled');
          }
        });
      });
    </script>

  </head>
  <body>

    <div class="page">

这适用于大多数表单，但这是我使用此代码的主要原因。

任何人都明白为什么这个不起作用？

Answer 1

而不是写这个： -

$('input[type="submit"]').attr('disabled', 'disabled');

你应该这样写： -

$('input[type="submit"]').prop('disabled','true');

单击后按钮不禁用
