Silverlight Javascript - Access and setting value of xaml's textbox in javascript

I have a text box named myTextbox in 开发者_JAVA技巧my xaml page, my question is how can i set it's text through javascript from my aspx page.

Create a public string property in the silverlight side, mark it with the ScriptableMemberAttribute, and bind the textbox text property to this public property. The property marked with the ScriptableMemberAttribute is visible to javascript.

The code to access a silverlight property from javascript depends on the names you have used for those objects, but you have examples here on how to access them:
