学用MVC4做网站六后台管理:6.1.3管理员修改密码

6.1.3修改密码

需要两个action。一个是点击修改密码的链接要显示修改密码的分部视图（对话框形式）；另一个是提交的处理action。

1、打开【AdministratorController】添加返回分部视图[ChangePassWord()]action

/// <summary>

        /// 修改密码

        /// </summary>

        /// <returns></returns>

        [AdminAuthorize]

        public PartialViewResult ChangePassWord()

        {

            return PartialView();

        }

添加视图

<div class="fs_wapper">

    @using (Html.BeginForm("ChangePassWord", "Administrator", FormMethod.Post, new { id = "admincha_form" }))

    {

        @Html.AntiForgeryToken()

        @Html.ValidationSummary()

        

        <table>

            <tr>

                <th>原密码</th>

                <td>

                    <input id="oldPwd" name="oldPwd" type="password" class="easyui-validatebox" data-options="required:true,validType:['length[6,256]']" />

                    </td>

            </tr>

            <tr>

                <th>新密码</th>

                <td>

                    <input id="newPwd" name="newPwd" type="password" class="easyui-validatebox" data-options="required:true,validType:['length[6,256]']" />

                    </td>

            </tr>

            <tr>

                <th>重复密码</th>

                <td>

                    <input id="confirmPwd" name="confirmPwd" type="password" class="easyui-validatebox" validType="equalTo['#newPwd']" />

                    </td>

            </tr>

        </table> 

    }

</div>

<div style="margin:20px;">

    <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-ok" onclick="AdminCPwdSave()">保存</a>

</div>

2、添加修改密码处理action[ChangePassWord(string oldPwd,string newPwd)],返回JsonData类型。

[AdminAuthorize]

        [HttpPost]

        public JsonResult ChangePassWord(string oldPwd,string newPwd)

        {

            JsonData _jdata = new JsonData();

            if (ModelState.IsValid)

            {

                var _admin = AdministratorController.AdminInfo;

                if (_admin == null)

                {

                    _jdata.Success = false;

                    _jdata.Msg = "登录已超时，请重新登录！";

                }

                else if (Common.Sha256(oldPwd) != _admin.PassWord)

                {

                    _jdata.Success = false;

                    _jdata.Msg = "原密码错误！";

                }

                else

                {

                    _admin.PassWord = Common.Sha256(newPwd);

                    if (adminRsy.Modify(_admin))

                    {

                        _jdata.Success = true;

                        _jdata.Msg = "保存成功√！";

                    }

                    else

                    {

                        _jdata.Success = false;

                        _jdata.Msg = "数据未能保存到数据库！";

                    }

                }

            }

            else

            {

                var _eItem = ModelState.Where(m => m.Value.Errors.Count > 0);

                foreach (var i in _eItem)

                {

                    _jdata.MsgLsit.Add(i.Key, "验证失败！");

                }

            }

            return Json(_jdata);

        }

3、打开Administrator.js添加两个函数，ShowChangePwdDlg(url)用户显示修改密码的对话框url就是对话框加载的视图url，AdminCPwdSave()用来进行提交的客户端处理。

//显示修改密码窗口

function ShowChangePwdDlg(url) {

    $(document.body).append("<div id='cPwdDlg'></div>");

    $('#cPwdDlg').dialog({

        title: "修改密码",

        width: 480,

        height: 260,

        closed: false,

        cache: false,

        href: url,

        modal: true,

        onClose: function () { $(this).dialog("destroy"); }

    });

}

//修改密码保存

function AdminCPwdSave() {

    $('#admincha_form').form('submit', {

        success: function (data) {

            

            var rt = jQuery.parseJSON(data);

            if (rt.Success) {

                $.messager.alert("保存成功", rt.Msg, "", function () {

                    location.href = $("#btn_Logout").attr("href");

                    $("#cPwdDlg").dialog("destroy");

                    

                });

            }

            else {

                var msg = "";

                if (rt.MsgLsit != undefined) {

                    $.each(rt.MsgLsit, function (i, val) {

                        msg += "<li>" + i + ":" + val + "</li>";

                    });

                }

                if (msg != "") msg = rt.Msg + "<br /> <p> 原因如下：" + "<ul>" + msg + "</ul></p>";

                else msg = rt.Msg;

                $.messager.alert("保存失败", msg, "error");

            }

        }

    });

}

待续！
