ASP Razor Syntax and examples

1. Mixed HTML and razor scripts

Knowledge Points: (1). cshtml How to reference Access data, (2). If for and HTML nesting

@using system.data@using CIIC. Tcp. entity;@{List<taut_menuentity>Menulist = (List<taut_menuentity>) session["Navigatemenu"];}<navclass= "Navbar-default navbar-static-side"role= "Navigation">    <Divclass= "Sidebar-collapse">        <ulclass= "NAV"ID= "Side-menu">            <Liclass= "Nav-header">                <Divclass= "Dropdown profile-element">@Html. ActionLink ("XXX Platform", ".. \\Login\\FirstPage ", new {id =" ", Loginuserid = Viewbag.loginuserid As String}, new {style =" Font-size:large;font-wei Ght:bold "})</Div>                <Divclass= "Logo-element">in+</Div>            </Li>            <!--Permissions Menu Start -@if (menulist! = null) {foreach (taut_menuentity item in menulist) {if (item. level = = 1) {<Liclass="">                           <ahref= "@item. Url ">                                <Iclass= "fa Fa-th-large"></I><spanclass= "Nav-label"data-i18n= "Nav.dashboard">@item. ModuleName</span><spanclass= "FA Arrow"></span>                           </a>                           <ulclass= "Nav nav-second-level collapse">@{List<taut_menuentity>submenulist = menulist.findall (t = = T.modulename = = Item. MenuName && t.level.value==2). (T=>t.orderid).                                ToList (); foreach (var subitem in submenulist) {<Liclass=""><ahref= "@subItem. Url">@subItem. MenuName</a></Li>                                }                            }                           </ul>                       </Li>                    }                }            }            <!--Permission Menu End -        </ul>    </Div></nav>

2. Layout-related methods @RenderSection

Part One: Define the "submodule" placeholder to be inserted in _layout.cshtml

<type= "Text/javascript">   @RenderSection (" Headscript "  false</script>

Section Two: defining the corresponding fill block in the xxx.cshtml

Headscript {    function Del_comfire ()    {        if (Confirm ("OK delete?"))        {           return true;        }        Else{this;}}    }

3. Common methods in templates

@{  ViewBag. Xxx;}

@Url. Content ("Xxx") "  //Generate only link text <href=" @Url. Content ("~/ Content/site.css ")" rel= "stylesheet"  type= "text/css"/>< src = "@Url. Content ("~/scripts/jquery-1.4.4.min.js ")" Type    = "Text/javascript"></script>

4.Html helper Methods

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

< Li >@{html.renderaction ("Cartsummary", "ShoppingCart");} </ Li >  //reference Partialviewresult 

@{html.renderpartial("somepartial");//note with curly braces

@{   String message = "<strong>this is bold!  </strong>";} < span >@Html.Raw(message)</span>

5.PartialViewResult Technology

Call the other controller and action in the template, return it to the result fill template, refer to the Html.renderaction () method

6. Parentheses syntax in a template

If you write directly @rootname.models there will be a compile error

//View cshtml The experimental code and Syntax phenomena @{    string rootname= "MyApp";} < span >@ (rootname). Models</span>

7.Razor Native href method 8.Switch condition to judge example 9.Razor template annotation syntax and template literal output 10.HTML encoding is @html. Raw () Method 11. JavaScript encoding is the @ajax.javascriptencode () method
