JQuery - 留言之后，不重新加载数据，直接显示发表内容

留言板中，发表信息的时候，使用Ajax存储到后台数据库，如果存储成功，不重新加载数据库，直接显示发表内容。

代码：

var Nicehng = '';
var kkimgpath = '';
var text = '';

$(function () {
    if ($(document).scrollTop() != 0) {
        //刷新之后，回到顶部
        $('body,html').animate({ scrollTop: 0 }, 300);
    }
    //点击发表留言
    $("#submit").click(function () {
        editor.sync();
        text = $.trim($('#KindEditor').val());//获取KindEditor的内容
        if (text == "") {
            art.dialog({ id: 'TS', width: 325, height: 170, content: '请输入内容！' });//显示提示文本框
        }
        else {

            Nicehng = $.trim($("#NiCheng").val());
            if (Nicehng == "") {
                Nicehng = '匿名';
            }
            var IgP = Imgpath();
            kkimgpath = "../Images/demopage/image-" + IgP + ".jpg";

            $.ajax({
                type: "POST",
                url: "Handeler/Ajax.ashx",
                data: "NiCheng=" + Nicehng + "&Imgpath=" + kkimgpath + "&text=" + text + "",
                success: function (msg) {
                    if (msg == "Null") {
                        art.dialog({ id: 'TS', width: 325, height: 170, content: '参数为空，请联系管理员！' });
                    }
                    if (msg == "True") {
                        PageBindData();//当数据库存储成功时，在前台显示发表内容。
                        //清空
                        $("#NiCheng").val();
                        $("#Radio1").attr("checked","checked");
                        $("#KindEditor").val();
                        //回到顶部
                        $('body,html').animate({ scrollTop: 0 }, 500);
                    }
                    if (msg == "False") {
                        art.dialog({ id: 'TS', width: 325, height: 170, content: '发表失败！' });
                    }
                }
            });
        }
    })

    //获取Radio选中图片的值
    function Imgpath() {
        var val = $('input:radio[name="Img"]:checked').val();
        if (val == null) {
            return "";
        }
        else {
            return val;
        }
    }

    function PageBindData() {
        var mydate = new Date();
        var t = mydate.toLocaleString();
        var imgpath = kkimgpath;
        var name = Nicehng;
        var ip = '121.123.123.12';
        var content = text;
        var time = t;
        //$("#newcontent").prepend("<div><ul><li><div><img src='" + kkimgpath + "'/></div></li><li><div><span>" + name + "</span></div></li><li><div><span>" + ip + "</span></div></li></ul></div><div><div>" + content + "</div><div><ul><li ><span >2楼</span></li><li ><span>" + time + "</span></li><li><a href='####' >回复</a></li></ul></div></div>");
