IFrame实现的无刷新(仿ajax效果)...

<iframe style="display:none;" name="gg"></iframe>
        <form action="/demo/add" method="post" target="gg">
            <table class="info_form table table-striped">
                <tr>
                    <td>姓名</td>
                    <td><input name="name" /></td>
                </tr>
                <tr>
                    <td>年龄</td>
                    <td><input name="age" /></td>
                </tr>
                <tr>
                    <td>颜值</td>
                    <td><input name="yz" /></td>
                </tr>
            </table>
            <button class="btn btn-default" type="submit">确定</button>
        </form>
<script>
function call_back(){
　　alert("睡你妈逼，起来嗨！");
}
</script>
注意:form的target属性。设置为iframe的name属性值。这样的话后台返回的view会显示在iframe中

public ActionResult Add()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Add(my m)
        {
            testEntities t = new testEntities();
            t.my.Add(m);
            t.SaveChanges();
            return Content("<script>parent.call_back();</script>");
        }
