Multiple methods of using SilverLight to call javascrip

Although silverlight is sufficient for developing various page types, we consider the following scenario: What should we do if we want to obtain the browser width? In silverlight, this method is not available for direct use, but we know how to use webpage special effects to get the browser width. I will introduce two methods to call javascript.

1. execute javascript in silverlight

First, add the namespace: system. windows. browser;

Htmlpage. window. eval ("alert ('javascript executed ')");

 

2. Call the javascript function on the host page:

For example, we have the following javascript Functions on the host page:

 

Function prompt (){
Alert ("executed host js ");
}
 

 

Add the following code to silverlight:

 

Scriptobject urivirtual = htmlpage. window. getproperty ("prompt") as scriptobject;
Urivirtual. invokeself ();

 

In this way, the prompt function on the host page is called.
