CHAPTER 11

Steps 3 and 4: Importing and executing the JSF

Flash panels pass JSF to Fireworks via the MMExecute() method in ActionScript. When an exported

SWF is run inside Fireworks as a Flash panel, MMExecute() passes the JavaScript directly to Fireworks.

Fireworks then executes the JavaScript and returns the resulting value to Flash (if any):

var result = MMExecute(jsfCode);

The JavaScript is passed to MMExecute() as a string, which means you must escape quotation marks

and potentially double- escape text that has already been escaped in JavaScript strings. That sounds

more confusing than it actually is. The following example executes the setFillColor() line of code

in Flash using MMExecute():

MMExecute("fw.getDocumentDOM().setFillColor(\"#99cc33\");");

Notice that the entire string is wrapped with quotation marks, and the inner quotes surrounding

#99cc33 have been escaped: \"#99cc33\". For single lines of JavaScript, this method of execution

works well. As your JavaScript grows in complexity, however, escaping large sequences of code

becomes laborious and introduces the potential for error.

One way around this for simple commands is to paste the JSF into a Flash TextField. Let’s use this

approach for our Draw Rect example:

1. Create a new TextField on the stage.

2. Change its text type to Dynamic Text and give it an instance name of jsfCode_txt (see

Figure 11-3).

3. Move this TextField off the stage so that it is not visible at runtime.

4. Paste the contents of the Draw Rect command directly into this TextField.

The Fireworks JavaScript is now available to you directly within the Flash document, accessible via

jsfCode_txt.text, and you didn’t have to make any modifications to the code at all.
