A preliminary study of Silverlight 5 (C #)

After a list, you have to use Silverlight 5来 to make a project, never touching this thing before, for work. It's up to you to bite the bullet. Groping for a night, big to sort out some of the items required in the following as a preliminary record:

Silverlight 5 How to talk to JavaScript

Silverlight 5 belongs to the client, and the client is communicating with the server, and the first thing I think about is the JavaScript-based Ajax adhesive. So start by interacting with JavaScript from Silverlight 5.

One, Silverlight 5 speaks, JavaScript listens

从Silverlight 5里向Javascript发送程序执行请求。
Silverlight 5端代码详细例如以下： 

HtmlPage.Window.Invoke("Javascript函数方式""传值-Oyiboy");

The code above is able to execute JavaScript script code directly in Silverlight 5 and send the necessary data out.

Second, JavaScript to speak. Silverlight 5 Listen

Javascript使用ajax获取server端数据后发送给Silverlight 5，以达到Silverlight 5与server端的交互效果。
Silverlight 5端代码详细例如以下：

        //设置值        [ScriptableMember()]//这行是关键。必须有这个javascript才干请求到这种方法        publicvoidsetVal(string D)        {            this.textView.Text = D;        }        //javascript主动要求返回值        [ScriptableMember()]        publicstringreturnVal()        {            returnthis.textView.Text;        }

Html代码调整：须要在Silverlight 5插件的object代码内里加入下面參数设置句。以达到插件在载入后获取siliverlight对象。

<param name="onLoad"value="siliverLoaded" />

Javascript代码详细例如以下：

        //siliverlight Object        varSiliverlightobj =NULL;//The Silverlight 5 onload event-triggered function set in the above HTML code         function siliverloaded(sender, args) {Siliverlightobj = Sender.gethost (); }//The. Buttonset and. Buttonreu in the code below are two buttons with these class. The button won't be written out in detail.        //This is the Setval method that executes within Silverlight 5$(". Buttonset"). Click ( function () {SiliverlightObj.Content.Main.setVal ("JavaScript passed in value-oyiboy"); })//This is the ReturnVal method that executes within Silverlight 5$(". Buttonreu"). Click ( function () {Alert (SiliverlightObj.Content.Main.returnVal ()); });

The above several ways, the flexible use of live basically completely conquer the Silverlight 5 and server side of the communication between, OK, although this article of the topic is Silverlight 5 and JavaScript. But finally the goal is Silverlight 5 and server side of the interaction, anyway Ajax is not a new thing, so it skipped.

Sentiment: Through the Silverlight 5 object SiliverlightObj.Content.Main this big channeling thing to see, Siliverlightobj still can do a lot of other things, detailed also must slowly grope, suppose later have need to use words. may also be out of this explanatory article, perhaps.

2015-07-10 Trap:
Main in SiliverlightObj.Content.Main refers to the name of the interview in the Application_Startup event App.xaml in Silverlight, with detailed code such as the following:

        privatevoidApplication_Startup(object sender, StartupEventArgs e)        {            thisnew MainPage();            System.Windows.Browser.HtmlPage.RegisterScriptableObject("Main"this.RootVisual);        }

From the code. Suppose there are multiple XAML pages. Just to register a different name here is to be able to refer to a JavaScript method that is declared within a different XAML page.
Just tidy up the code in App.xaml found this code just remember to give this to leak, today to fill back.
