Question

我几天来一直在解决问题。我想在没有页面刷新的情况下使用jquery验证和ajax调用。如果我只使用其中一个，代码工作正常但不在一起。我想要一个非常简单易懂的代码。

你可以帮助我解决问题吗？提前谢谢。

祝你好运，姿态

这样称呼：

$('#button_id').click(function(){
$("#myform").submit(function(e) {
  e.preventDefault();
}).validate({
  rules: {
            nev: {
              required: true,
              minlength: 2
            }
        },
        messages: {
            nev: {
              required: "We need your email address to contact you",
              minlength: 2
            }
        },
        submitHandler: function(form) {

                var nev=$("#nev").val();
                var action=$("#action").val();

                $.ajax({
                    type: "post",
                    url: "php.php",
                    data: "nev="+nev+"&action="+action,
                    success:function(result){
                        $("#nevem").html(result);
                    }
                });
            });
}); 
}); // no .submit() here
