.NET 一般处理程序完成AJAX操作

        jQuery("#btn").click(function () {
            var commentMessahe = jQuery("#CommentNote").val();
            var num = jQuery("#CommentNote").val().length;
            if (username != "") {
                if (commentMessahe != "") {
                    if (falgText) {
                        if (isvalidatecode) {
                            jQuery.ajax({
                                type: "Post",
                                url: "http://www.taogujie.com/Handler/JDCommentlHander.ashx?jd=AddComment",
                                data: { AppraisalID: appraisalID, CommentNote: commentMessahe },
                                success: function (data) {
                                    if (data.isok) {
                                        if (data.result == 1) {
                                            alert("评论成功");
                                            jQuery("#message").val("");
                                            window.location.href = "jd-" + appraisalID + ".html";
                                        }
                                        else {
                                            alert("评论失败");
                                        }
                                    }
                                }, error: function (XMLHttpRequest, textStatus, errorThrown) {
                                    alert("错误");
                                },
                            });
                        }
                    }
                }
            }
        });
