mvc area区域和异步表单,bootstrap简单实例

码农最怕眼高手低

今天来练习mvc Area技术和bootstrap以及异步表单的C#代码实现。

1.area区域架构对于建立复杂业务逻辑很有帮助,由  AreaRegistration.RegisterAllAreas()方法遍历路由表,获得所有注册的路由。参见

建立类库Common,下设一个文件夹BookStore

在其中建立model和controller。(注意引用System.Web.Mvc这个dll)

项目结构如图:

其中book.cs为model模型

namespace Common.BookStore
{
public class Book
{
public string bookName { get; set; }
public double price { get; set; }
public string bookType { get; set; }
public int num { get; set; }
}
}

注意controller中不要忘了继承Controller

namespace Common.BookStore
{
public class BookCurdController:Controller
{
    //添加页面
public ActionResult BookAdd()
{
return View();
}
    //模拟添加操作页面
public ActionResult _BookAdd(Book bookModel)
{
bookModel.num += ;
return View(bookModel);
}
}
}

2.建立一个基本mvc程序,我用的mvc4,在根目录下建立Areas文件夹,然后右键-添加-区域,输入我们的BookStore

这样我们添加了一个区域,删除其中的controller和model文件夹。

接着对生成的BookStoreAreaRegistration进行修改

    public class BookStoreAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
         //此为区域的名称,与我们的区域文件夹同名
return "BookStore";
}
} public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"BookStore_default",
"BookStore/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
//命名空间不可少
new string[] { "Common.BookStore" } );
}
}

生成Common类库,在web站点添加对其的引用。

3.现在进行页面部分的制作,我们先添加bootstrap文件,我从ExtJs源码中把bootstrap几个文件扣了出来,添加到web程序中,就像这样

接着,我们添加页面上的引用(或者你把它们放到一个局部视图或者模板视图中也行)

    <link href="@Url.Content("~/Content/bootstrap/css/bootstrap.css")" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery-1.7..js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.validate.min.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Content/bootstrap/js/jqBootstrapValidation.js")"></script>

套用一个bootstrap框架

<div class="container-fluid" style="margin-top:30px;">
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label class="control-label col-xs-4" for="bookName">书名:</label>
<div class=" col-xs-4">
<input id="bookName" class="form-control" type="text" name="bookName" value="" />
</div>
</div>
</div>
    </div>
</div>

在这里说明一下,bootstrap依循网格系统,分为12列,最基础的属性由less构建(所以想改造它,可以直接修改less),其中.col-xs-* 是针对小尺寸设备(<768px)的样式。具体参考

http://www.w3cschool.cc/bootstrap/bootstrap-grid-system.html

在设置完样式之后,我们引入异步代码

  @using (Ajax.BeginForm(
          //指定action,controller
          "_BookAdd", "BookCurd", null,
new AjaxOptions()
{
           //更新还是替换
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
//标记要更新的div,页面部分由jquery.validate.unobtrusive.js完成
UpdateTargetId = "showMsg",
//提交成功
OnSuccess = "OnSuccess",
//提交失败
OnFailure = "OnFailure",
//完成
OnComplete = "OnComplete"
},
//这个参数设置form表单的属性
htmlAttributes: new { name = "nbform", id = "nbform", @class = "form-horizontal" }))
{ .......
}

最后页面如下

@{
Layout = null;
} <!DOCTYPE html> <html>
<head>
<meta name="viewport" content="width=device-width" />
<title>图书添加</title>
<link href="@Url.Content("~/Content/bootstrap/css/bootstrap.css")" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery-1.7..js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.validate.min.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")"></script>
<script type="text/javascript" src="@Url.Content("~/Content/bootstrap/js/jqBootstrapValidation.js")"></script>
<script type="text/javascript">
$(function () {
$.AddCheckBoxRadioLinster("nbform");
});
function OnSuccess() {
alert("提交成功");
}
function OnFailure() {
alert("提交失败");
}
function OnComplete() { }
</script>
</head>
<body>
<div class="container-fluid" style="margin-top:30px;">
@using (Ajax.BeginForm("_BookAdd", "BookCurd", null,
new AjaxOptions()
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "showMsg",
OnSuccess = "OnSuccess",
OnFailure = "OnFailure",
OnComplete = "OnComplete"
},htmlAttributes: new { name = "nbform", id = "nbform", @class = "form-horizontal" }))
{ <div class="row">
<div class="col-xs-12">
<div class="form-group">
<label class="control-label col-xs-4" for="bookName">书名:</label>
<div class=" col-xs-4">
<input id="bookName" class="form-control" type="text" name="bookName" value="" />
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label class="control-label col-xs-4" for="price">价格:</label>
<div class="col-xs-4">
<input id="price" class="form-control" type="text" name="price" maxlength="" minlength="" data-validation-minlength-message="价格最少1位!" data-validation-required-message="不能为空!" required />
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label class="control-label col-xs-4" for="bookType">种类:</label>
<div class="col-xs-4"> <label class="checkbox-inline" >
<input type="checkbox" id="bookTypeCheckbox" name="bookTypeCheckbox" value="电子书"/>电子书
</label>
<label class="checkbox-inline" >
<input type="checkbox" name="bookTypeCheckbox" value="印刷版"/>印刷版
</label>
<input type="hidden" id="bookType" name="bookType" /> </div>
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
<label class="control-label col-xs-4" for="num">数量:</label>
<div class="col-xs-4">
<input id="num" class="form-control" type="text" name="num" maxlength="" minlength="" data-validation-required-message="不能为空!" required />
</div>
</div>
</div>
</div>
<div class="row" >
<div class="col-xs-3 col-md-offset-4">
<button type="submit" class="btn btn=default">提 交</button>
</div>
</div> }
</div>
<div class="container" id="showMsg"> </div>
</body>
</html>

效果如图:

这里还要说明一下,$.AddCheckBoxRadioLinster("nbform");这个是jqBootstrapValidation.js中的函数很好用。我们看一下他的内部实现

  $("#" + formId + " input[type='checkbox'],input[type='radio']").each(
function () {
$(this).change(function() {
var name = $(this).attr("name");
var value = "";
$("#" + formId + " input[name='" + name + "']:checked").each(function() {
value = value + ";" + $(this).val();
});
var length = $(this).attr("type") == "radio" ? : ;
if (value == "") {
$("#" + $(this).attr("name").substr(, $(this).attr("name").length - length)).val("-1");
} else {
$(this).parents(".form-group").first().removeClass("error");
$("#" + $(this).attr("name").substr(, $(this).attr("name").length - length)).attr("value",length == ? value.substr(, length) : value + ";");
}
});
}
);

以字符串拼接的方式来约束字段和处理,它不但可以动态绑定checkbox,radio还可以绑定select下拉框。。。。。。
