Asp.net MVC 3实例学习之ExtShop（三）——完成首页
首页主要包括两部分，主体部分显示15个最新的的商品，右边则显示10条最新的优惠信息。主体部分可以直接使用传入的数据生成，也可以通过分类列表的方法生成，看个人喜好。而优惠信息则使用分类的方法生成。
在完成首页前，需要做点准备功夫，因为需要显示评价，所以首先到地址“http://plugins.jquery.com/project/Star_Rating_widget ”下载一个名称为“jQuery UI Stars”的插件。插件下载后，将jquery.ui.stars.css文件添加到Content文件夹，jquery.ui.stars.min.js文件添加到Scripts文件夹，而jquery.ui.stars.gif则放到images文件夹。最后还需要修改一下jquery.ui.stars.css文件中背景图片的路径。
在母版页_Layout.cshtml的head中增加以下文件的引用：
| 1 | < link href = " @Url.Content( " ~ / Content / jquery . ui . stars . css " ) " rel = " stylesheet " type = " text/css " / > |
| 2 | < script src = " @Url.Content( " ~ / Scripts / jquery - ui . min . js " ) " type = " text/javascript " > < / script > |
| 3 | < script src = " @Url.Content( " ~ / Scripts / jquery . ui . stars . min . js " ) " type = " text/javascript " > < / script > |
| 4 |
现在要完成首页的整体布局，打开Index.cshtml，讲ViewBag.Title修改为“首页——Ext商店”，然后加入以下代码：
| 1 | < div id = " contentMain " > |
| 2 | < span class = " header " > 最新产品 < / span > |
| 3 | @ { Html . RenderAction ( " Homepage " , " Product " ) ; } |
| 4 | < / div > |
| 5 | < div id = " contentRight " > |
| 6 | < span class = " header " > 优惠信息 < / span > |
| 7 | @ { Html . RenderAction ( " RightList " , " News " ) ; } |
| 8 | < / div > |
| 9 |
代码中，最新产品和优惠信息的数据都将从partial视图获取。下面在Site.css中加入以下css：
| 1 | #contentMain { float : left ; width : 580px ; display : block ; border-left : 1px solid #d3d3d3 ; border-right : 1px solid #d3d3d3 ; border-bottom : 1px solid #d3d3d3 ; } |
| 2 | #contentMain .header { width : 570px ; height : 28px ; background : url(/images/bk.gif) repeat-x ; line-height : 28px ; display : block ; color : #000 ; font-size : 14px ; margin : 0px ; padding-left : 10px ; } |
| 3 | #contentMain ul { float : left ; width : 180px ; display : block ; padding : 0 0 10px 10px ; } |
| 4 | #contentMain li { list-style-type : none ; } |
| 5 | #contentMain .title { height : 56px ; line-height : 14px ; width : 170px ; display : block ; font-size : 12px ; } |
| 6 | #contentMain .rating -title { float : left ; } |
| 7 | #contentMain .rating { float : left ; width : 90px ; } |
| 8 | #contentMain img { border : 0px ; width : 170px ; height : 190px ; } |
| 9 | #contentMain a { text-decoration : none ; color : #000 ; } |
| 10 | #contentMain a:hover { text-decoration : underline ; } |
| 11 | #contentMain a:visited { text-decoration : none ; color : #000 ; } |
| 12 | #contentRight { float : right ; width : 200px ; display : block ; border : 1px solid #d3d3d3 ; padding : 1px ; } |
| 13 | #contentRight .header { background : url(/images/leftHeader.jpg) repeat-x ; height : 28px ; line-height : 28px ; width : 190px ; display : block ; color : #fff ; font-size : 14px ; margin : 0px ; } |
| 14 | #contentRight span { width : 180px ; display : block ; height : 20px ; line-height : 20px ; background : transparent url(/images/point02.jpg) no-repeat scroll 0 10px ; padding-left : 10px ; margin-left : 5px ; } |
| 15 | #contentRight a { color : #000 ; } |
| 16 | #contentRight a:hover { text-decoration : underline ; } |
| 17 | #contentRight a:visited { color : #000 ; } |
| 18 |
现在要完成最新产品的显示。在Controllers文件夹添加一个“ProductController”的控制器，首先加入对“Extshop.Models”的引用，然后添加以下代码：
| 1 | [ ChildActionOnly ] |
| 2 | public ActionResult Homepage ( ) |
| 3 | { |
| 4 | var q = dc . T_Products . OrderByDescending ( m = > m . CreateTime ) . Take ( 15 ) ; |
| 5 | return PartialView ( q ) ; |
| 6 | } |
| 7 |
代码只是很简单的从数据库取出15条记录，然后返回Partial视图。在“Homepage”上单击鼠标右键，然后创建一个Partial视图，在视图中添加以下代码：
| 1 | @ model IEnumerable < Extshop . Models . T_Products > |
| 2 | @ { |
| 3 | foreach ( var c in Model ) |
| 4 | { |
| 5 | < ul > |
| 6 | < li > < a href = ' @ Url . Action ( " Details " , " Product " , new { id = c . ProductID } ) ' > < img src = ' / Images / products / @ c . SamllImageUrl ' alt = " @c.Title " / > < / a > < / li > |
| 7 | < li class = ' title ' > < a href = ' @ Url . Action ( " Details " , " Product " , new { id = c . ProductID } ) ' > @ c . Title < / a > < / li > |
| 8 | < li > 市场价： < del > @ c . MarketPrice . ToString ( " C " ) < / del > < / li > |
| 9 | < li > 当前价： @ c . UnitPrice . ToString ( " C " ) < / li > |
| 10 | < li > < span class = " rating-title " > 评 价： < / span > |
| 11 | < div class = ' rating ' id = " @c.ProductID.ToString( " rat - 0 " ) " > |
| 12 | < input name = " @c.ProductID.ToString( " Star0 " ) " type = " radio " class = " star " disabled = " disabled " value = " 1 " @ ( c . TotalRating = = 1 ? " checked='checked' " : " " ) / > |
| 13 | < input name = " @c.ProductID.ToString( " Star0 " ) " type = " radio " class = " star " disabled = " disabled " value = " 2 " @ ( c . TotalRating = = 2 ? " checked='checked' " : " " ) / > |
| 14 | < input name = " @c.ProductID.ToString( " Star0 " ) " type = " radio " class = " star " disabled = " disabled " value = " 3 " @ ( c . TotalRating = = 3 ? " checked='checked' " : " " ) / > |
| 15 | < input name = " @c.ProductID.ToString( " Star0 " ) " type = " radio " class = " star " disabled = " disabled " value = " 4 " @ ( c . TotalRating = = 4 ? " checked='checked' " : " " ) / > |
| 16 | < input name = " @c.ProductID.ToString( " Star0 " ) " type = " radio " class = " star " disabled = " disabled " |
