您好我有一个主类

//main.as

package {
    public class main {
    	public var testGlobal:string = "testValue";

    }
}


//pop.as

package {
    public class pop {
    	function pop():void {
    		trace("testGloabl from main.as" + testGlobal);
    	}
    }
}

我怎样才能在pop.as的testGlobal值宽出使用一个主类对象。 是否有全局变量??

How can i get the testGlobal value on pop.as width out using a main class Object. Is there any method of Global variables??

如何在AS3中使用全局变量。

How to use global variables in AS3 .

推荐答案

如果你绝对肯定必须有在AS3一个全局变量，你总是可以创建这样的源文件夹的顶层文件：

If you absolutely positively have to have a global variable in as3, you could always create a file in the top-level of your source folder like this:

MULTIPLIER.as

MULTIPLIER.as

package
{
    public var MULTIPLIER:int = 3;
}

然后，当你需要你事半功倍，你可以参考，无论你需要的是这样的：

Then, whenever you need your multiplier you could reference wherever you need it like this:

DoSomeMultiplying.as

DoSomeMultiplying.as

package multiplying
{
    public class DoSomeMultiplying
    {
        public function multiplyMe(n:int):int
        {
            var m:int = n * MULTIPLIER;
            MULTIPLIER = m;
            return m;
        }
    }
}

不过，我的的强烈建议你不要这样做！的这是可怕的不好的做法，可怕的缓慢，那么，就可怕！

但是它是，它可以创建在默认包一个全局变量或常数充当全局常量或变量

But there it is, it is possible to create a global variable or constant in the default package to act as a global constant or variable.

声明全局函数在AS3

请注意，您也可以以同样的方式创建全局的功能，而你并不需要使用的import语句（类似内置跟踪功能）：

Note that you can also create global functions in the same way, and you don't need to use an import statement for (similar to the built-in trace function):

greet.as

package {
  public function greet():String { return "Hello World" }
}

类似于全局变量，该全局函数是从任何地方访问，无需导入语句：

Similar to the global variable, this global function is accessible from anywhere without an import statement:

package bar {
    public class foo
    {
        public function foo():void
        {
            trace("New foo says: "+greet()+", no import necessary");
            // New foo says: Hello World, no import necessary
        }
    }
}
