The wrapper's HTML page includes the following:

<script> block 

The script block embeds the JavaScript file. This JavaScript file defines the <object> and <embed> tags that embed the SWF file in the HTML page. This block is for users who have enabled JavaScript in their browser.

<noscript> block 

The code in the <noscript> block uses <object> and <embed> tags to embed the SWF file in the HTML page for users who have disabled JavaScript in their browser. The <noscript> block is useful if your application requires JavaScript (for example, if you use the ExternalInterface API in your application). You can use this block to warn users that they will have limited functionality, or redirect them to another site. For a simple application, however, your <noscript> block typically contains identical tags as they are defined in the JavaScript file. For more complex wrappers that include support for Express Install, the <script> block can include a considerable amount of JavaScript code.
