这篇文章主要介绍了.NET的Ajax请求数据提交实例,较为详细的分析了Ajax请求、数据的提交以及参数的传递技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了.NET的Ajax请求数据提交实现方法。分享给大家供大家参考。具体如下:

复制代码 代码如下:

            } 
        }); 
        $('.loginBtn').on('click', function () { 
            $(".warn").hide(); 
            var pwd = $('.passwordStyle').val(); 
            if (pwd == '') { 
                $(".warn").show().html('请输入密码'); 
                return false; 
            } 
            var data = $("#formData").serialize(); 
            $.post("/login/checkLoginInfo", data, function (ajaxObj) { 
                //回传内容{status: 1(success)/0(fail),} 
                if (ajaxObj.status == 0 || status == null) { 
                    $(".warn").show().html('用户名或密码错误!'); 
                } else {

                } 
            }, "json");
