Using ActionScript in Flex applications 95

The following example declares a variable and a function:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>

<![CDATA[

public var z:Number;

public function doSomething():void {

z = z + 1; // This must be in a function.

}

]]>

</mx:Script>

</mx:Application>

Using special characters in ActionScript

Special characters are any characters that might confuse the XML parser. The contents of

<mx:Script> tags are treated as XML by Flex, but Flex does not parse text in a CDATA

construct so that you can use XML-parsed characters such as angle brackets (< and >) and

ampersand (&). For example, the following script that includes a less than (<) comparison in

the for statement must be in a CDATA construct:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>

<![CDATA[

public function changeText():void {

for (var i:int=1; i<10; i++) {

ta1.text += "Hello world\n";

}

]]>

</mx:Script>

<mx:TextArea id="ta1" width="100" height="300"/>

<mx:Button id="b1" label="Click Me" click="changeText()"/>

</mx:Application>
