ASP.NET MVC Razor语法及实例

1.混合HTML与Razor脚本

知识点:(1).cshtml怎样引用访问数据, (2).if  for 与html嵌套

@using System.Data
@using CIIC.TCP.Entity;
@{
    List<taut_MenuEntity> MenuList = (List<taut_MenuEntity>)Session["NavigateMenu"];
}
<nav class="navbar-default navbar-static-side" role="navigation">
    <div class="sidebar-collapse">
        <ul class="nav" id="side-menu">
            <li class="nav-header">
                <div class="dropdown profile-element">
                    @Html.ActionLink("Xxx平台", "..\\Login\\FirstPage", new { id = "", loginUserId = ViewBag.loginUserId as string }, new { style = "font-size:large;font-weight:bold" })
                </div>
                <div class="logo-element">
                    IN+
                </div>
            </li>
            <!--权限菜单开始-->
            @if (MenuList != null)
            {
                foreach (taut_MenuEntity item in MenuList)
                {
                    if (item.Level == 1)
                    {
                       <li class="">
                           <a href="@item.Url">
                                <i class="fa fa-th-large"></i><span class="nav-label" data-i18n="nav.dashboard">@item.ModuleName</span><span class="fa arrow"></span>
                           </a>
                           <ul class="nav nav-second-level collapse">
                            @{
                                List<taut_MenuEntity> SubMenuList = MenuList.FindAll(t => t.ModuleName == item.MenuName && t.Level.Value==2 ).OrderBy(t=>t.OrderId).ToList();
                                foreach (var subItem in SubMenuList)
                                {
                                    <li class=""><a href="@subItem.Url">@subItem.MenuName</a></li>
                                }
                            }
                           </ul>
                       </li>
                    }
                }
            }
            <!--权限菜单结束-->
        </ul>
    </div>
</nav>

2.布局相关方法 @RenderSection

部分一:在_Layout.cshtml 中定义待插入的"子模块"占位符

<script type="text/javascript">
   @RenderSection("HeadScript", false)
</script>

部分二:在Xxx.cshtml中定义对应的填充块

@section HeadScript{
    function del_comfire()
    {
        if(confirm("确定删除?"))
        {
           return true;
        }
        else{
            this;
        }
    }
}

3.模板中的常用方法

@{
  ViewBag．Xxx;
}

@Url.Content("Xxx")"  //仅仅生成链接文本
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script>

4.Html助手方法

@Html.ActionLink("Create New", "Create")

<li>@{Html.RenderAction("CartSummary", "ShoppingCart");}</li>  //参考PartialViewResult

@{Html.RenderPartial(“SomePartial”);//注意有大括号

参考

@{
   string message = “<strong>This is bold!</strong>”;
}
<span>@Html.Raw(message)</span>

5.PartialViewResult技术

在模板中调用其它Controller和Action,将其返回结果填充模板,参考Html.RenderAction()方法

6.模板中的小括号语法

如果直接写@rootName.Models将会有编译错误

//视图cshtml中的实验代码和语法现象
@{
    string rootName="MyApp";
}
<span>@(rootName).Models</span>

7.Razor的原生Href方法

8.Switch条件判断例子

9.Razor的模板的注释语法以及模板字面值直接输出

10.HTML编码即@HTML.Raw()方法

11.JavaScript编码即@Ajax.JavaScriptEncode()方法

12.在页面里获取当前Action字面值

@{
    var curActionName = ViewContext.RouteData.Values["action"] == null ? "" : ViewContext.RouteData.Values["action"].ToString();
    ViewBag.Title = "顾问详细信息";
}
