MVC 知识点学习1

1、@Scripts.Render("~/bundles/kindeditor");@Styles.Render("~/Css/")   //(加载)引用bundles/kindeditor/kindeditor.js文件   @using System.Web.Optimization

2、@Html.TextArea("Information", new { style = "width:800px;height:400px" })   (@Html.Raw())

3、HashTable hash=new HashTable();    

     hash["id"]=1;   hash["url"]="../Home/Index";  

     return  Json(hash,""text/html;charset=UTF-8"");

4、$.post(‘@Url.Action("GetSth")‘,{},function(data) {   标注：GetSth为相同Controler下面的方法

       if (data.msg) {
            alert("请求成功一次");
       } else {
            alert("请求次数过多");
       }
   });

5、异步表单：

1>>>>>

@using (Ajax.BeginForm("GetDateTime", "Html", new AjaxOptions()
{
     HttpMethod = "post", //传输方式
     OnSuccess = "suc", //加载成功调用的js方法
     OnFailure="err", //出错调用的js方法
     LoadingElementId = "imgLoad" //请求所现实的元素
}))
{
<input type="text" name="txtName" />
<input type="submit" />
<div id="imgLoad">loding....</div>
}

2>>>>>

<script type="text/javascript">

function suc(resText) {
      alert(resText);
}; 

var xhr=new XMLHttpRequest();//ActiveXObject("Msxml2.XmlHttp");  ActiveXObject("Microsoft.XmlHttp");
function err(xhr) {
       alert(xhr.readyState)
}
</script>

3>>>>>

public ActionResult GetDateTime()

{
     string str =Request.Form["txtName"];
     System.Threading.Thread.Sleep(2000);
     return Content(DateTime.Now + "," + str);
}

IEnumerable<T> sources.Skip(pageSize * (pageIndex - 1)).Take(pageSize).ToList();
