javascript - 外部接口(interface)错误

Question

这是我用来在 javascript 中调用函数 calc 的代码:

import flash.external.ExternalInterface;

ExternalInterface.addCallback("asFunc", this, asFunc); 

function asFunc(str:String):Void {
    out.text = "JS > Hello " + str;
}

send_btn.addEventListener(MouseEvent.CLICK, clickListener);

function clickListener(eventObj:Object):Void {
    trace("click > " + mean.text);
    ExternalInterface.call("calc", mean.text);
}

但我收到以下错误:

1046: Type was not found or was not a compile-time constant: Void.

我在这里做错了什么？ (我修改了实时文档中的示例。)

Answer 1

Void 应该是小写。

像这样:

void
