bpflash_embed.js
Implementation of JavaScript functions useful for embedding the
BioPassword Flash client control in a web page.
The bpInsertFlash function embeds the Flash client on a web page. In order
to bypass the 'Press SPACEBAR or ENTER to activate and use this control'
message in the updated IE version, this function must exist in a seperate
".js" file.
To use functions found in this file, you should include the following line
somewhere in the '' portion of your HTML file:
(Note that the path to this file may need to be modified in the 'src' value)
Usage example:
