Flex Builder中的动作script3跟踪
|
这是代码，我正在使用Flex Builder 4.5，
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<s:Application xmlns:fx=\"http://ns.adobe.com/mxml/2009\"
xmlns:s=\"library://ns.adobe.com/flex/spark\"
xmlns:mx=\"library://ns.adobe.com/flex/mx\" minWidth=\"955\" minHeight=\"600\">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<fx:Script>
<![CDATA[
public var ss:Array = [\"a\", \"b\", \"c\"];
trace(ss[0]);
public var str:String = \"Good Luck\";
trace(str);
]]>
</fx:Script>
</s:Application>

是字段声明，是代码执行流程中的动作。将放在适当的范围内（在函数aka方法中），它将被编译和执行而没有任何问题。窝头菊
public function debugString() : void { // declare a local property, only this, \'debugString\' function can acess // or modify this property - it is deleted when this function finishes. var myString : String = \"Hello World\"; trace(myString); }public class HelloWorld { // Define a Class member property; all functions in this Class will be // able to access, and modify it. This property will live for as long as the // Class is still referenced. public var myString : String = \"Hello World\"; public function debugString() : void { // notice how we did not declare the \'myString\' variable inside // this function. trace(myString); } }class HelloWorld { public var myString : String = \"Hello World\"; // This will not work, because you can only access static properties // outside of a function body. This makes sense because a member property // belongs to each instance of a given Class, and you have not constructed // that instance yet. trace(myString); // This is the Class Constructor, it will be called automatically when a // new instance of the HelloWorld class is created. public function HelloWorld() { trace(myString); } }public class HelloWorld { // Here we define a static property; this is accessible straight away and you // don\'t even need to create a new instance of the host class in order to // access it, for example, you can call HelloWorld.MY_STRING from anywhere in your // application\'s codebase - ie: trace(HelloWorld.MY_STRING) public static var MY_STRING : String = \"Hello World\"; }
