JavaFX Applet Launch JavaScript
To make JavaFX applet deployment easier and portable across browsers, Sun has
developed a JavaScript function for launching JavaFX applets. This JavaScript
function is defined as
javafx(launchParams, appletParams)
. The second param-
eter,
appletParams
, is optional. To include this JavaScript code into your HTML
page, you must first reference it. The standardized location for this JavaScript
code is
http://dl.javafx.com/dtfx.js.
An example of using this in an HTML page is
<script src="http://dl.javafx.com/dtfx.js"></script>
Including this script provides JavaScript functions for automatic checking for the
correct Java version and defines the JavaScript function for loading the appropri-
ate JavaFX runtime archive files.
To use the JavaFX launch function,
javafx()
,
in an HTML page, include it
within a JavaScript section as shown in Listing 9.2.
Listing 9.2

<script>
javafx(
{
archive: "NasaImageBrowser.jar",
width: 500,
height: 500,
code: "nasaimagebrowser.Main",
name: "NasaImageBrowser"
}
);
</script>
Listing 9.3 shows using the JavaFX Applet launcher function in an HTML page.
The JavaScript code for the applet is shown in bold and includes two script sections.
