RSS Reader code implemented using jQuery's ajax function_jquery

Let’s take a look at the effect first:

First, an ascx page is needed to bind the content of the rss source to a ListView through an XDocument. The code is as follows:

Copy code The code is as follows:

protected void Page_Load(object sender, EventArgs e )
{
// For demo purposes.
System.Threading.Thread.Sleep(1000);

XDocument feedXML =
XDocument.Load("http://feeds .feedsky.com/csdn.net/dujingjing1230");

var feeds = from feed in feedXML.Descendants("item")
select new
{
Title = feed.Element ("title").Value,
Link = feed.Element("link").Value,
Description = feed.Element("description").Value
};

PostList.DataSource = feeds;
PostList.DataBind();
}

Copy code The code is as follows:

<asp:ListView runat="server" ID="PostList">
<LayoutTemplate>
<ul>
<asp :PlaceHolder runat="server" ID="itemPlaceholder" />
</ul>
</LayoutTemplate>
<ItemTemplate>
<li><a href= '<%# Eval("Link") %>'><%# Eval("Title") %></a><br />
<%# Eval( "Description") %>
</li>
</ItemTemplate>
</asp:ListView>

Next you need to create an aspx page to Display RSS content. Of course, this page uses jQuery's AJAX to get the above data.
HTML page code:

JS to implement ajax function:

Copy code The code is as follows :

$(document).ready(function() {
$.ajax({
type: "POST",
url: "RSSReader.asmx/GetRSSReader" ,
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$('#RSSContent').removeClass('loading');
$('#RSSContent').html(msg.d);
}
});
});

Finally is the content of the web service RSSReader.asmx:

Copy code The code is as follows:

public class RSSReader : System.Web.Services.WebService {
[WebMethod]
public string GetRSSReader()
{
Page page = new Page();
UserControl ctl =
(UserControl)page.LoadControl("~/RSSReaderControl.ascx");
page.Controls.Add(ctl);
StringWriter writer = new StringWriter();
HttpContext .Current.Server.Execute(page, writer, false);
return writer.ToString();
}
}

There is also an image used in the page, here it is No more uploading.
