我有一个使用xVal的MVC应用程序。我试图挂钩到jquery验证，以在表单有效后显示“加载”图形。当jquery验证表单时，我似乎找不到只显示qraphic的方法。
但是，它还会在单击按钮时禁用按钮，并且未经过验证会阻止用户重新提交表单，客户端错误将得到纠正。
有没有人有这方面的经验。

无论如何，我认为没有preventDefault（）你的提交肯定会被解雇。
$(function() { // make this code initialize when DOM loads
$('#frmXL').submit(function(e) {
e.preventDefault();
$('input[type="submit"]', this).replaceWith('<span id="loading"></span>'); //
});
});
