In some of your applications you may need to use Flash movies and JavaScript directly, without any prepackaged APIs such as FlashSound JavaScript API. You will enjoy more features, methods, and properties, but you'll have to take care of all the tiny details that are taken for granted when using FlashSound API, for example.

One of the "tiny" details is embedding the Flash object. The JavaScript file flashmoviecheck.js does exactly this, as well as other stuff. For example, it checks whether a Flash player exists (Flash plug-in or ActiveX control), and whether its version is higher than the minimum required by the application.

Use the Flash method PercentLoaded() to find out the percentage of the Flash movie already loaded. The syntax is:

 PercentLoaded()
This method returns the percent of the Flash Player movie that has streamed into the browser so far. Possible values are from 0 to 100. We still did not find a Flash movie that will yield PercentLoaded() less than 100%.

Use the following links to play, rewind, zoom in, zoom out, and find Percent Loaded:

Rewind | Play | Zoom In by 2x | Zoom Out by 2x | Percent Loaded

Here is the code:

<SCRIPT LANGUAGE="JavaScript" SRC="flashmoviecheck.js"></SCRIPT>
<A href="javascript://" onclick="javascript:mySwf.Rewind(); return false">Rewind</A> | 
<A href="javascript://" onclick="javascript:mySwf.Play(); return false">Play</A> |
<A href="javascript://" onclick="javascript:mySwf.Zoom(50); return false">Zoom In by 2x</A> | 
<A href="javascript://" onclick="javascript:mySwf.Zoom(200); return false">Zoom Out by 2x</A> | 
<A href="javascript://" onclick="javascript:alert(mySwf.PercentLoaded()); return false">Percent Loaded</A>
<SCRIPT LANGUAGE="JavaScript">
  Flash_embedSWF("swift3d.swf");
  var mySwf = window.document.sonify;
</SCRIPT>
