如何在Action Script 2中将变量传递给内联函数 [英] How to pass variables into inline functions in Action Script 2

问题描述

我具有以下功能，但似乎无法将myVar变量添加到内联函数中。我在这里做错了什么？我想发生的是，当我单击myMc时，它应该将myVar打印到控制台（ hello computer）。

I have the following function, but I can't seem to get the myVar variable into the inline function. What am I doing wrong here? What I would like to have happen is when I click on myMc, it should print myVar to the console ("hello computer").

function doSomething():Void
{   
    myVar = "hello computer";

    myMc.onRelease = function(){
        trace(myVar); //prints as "undefined"
    }
}

ps。 -我无法将myVar声明为全局变量或静态变量，因为在实际代码中，我正在解析XML，而myVar却在不断变化。

ps. - I cannot declare myVar as a global or static variable because in the real code, I'm parsing XML and the myVar is constantly changing.

推荐答案

这是一个范围问题-在as2中应用像这样的onRelease函数时，该函数的范围是您将函数应用于的MovieClip，而不是调用函数。

This is a scope issue - when you apply an onRelease function like this in as2, the scope of the function is the MovieClip you apply the function to, not the calling function.

由于您使用的是AS2并且MovieClip是动态的，因此可以直接将变量分配给MC：

Because you are using AS2 and MovieClip is dynamic, you can assign the variable to the MC directly:

function doSomething():Void
{   
    myMc.myVar = "hello computer";

    myMc.onRelease = function(){
        trace(this.myVar);
    }
}
