String 如果Objectsname取自字符串，如何使用Objects.function

我想知道这个概念是否可行：

情景： 一个阶段上的4个区域非常相似（例如网络摄像机会议，每个区域具有相同的功能）

按钮对象已编号（例如区域1有playbutton1、mutebutton1、namebutton1、namelabel1等）

每个区域都有一个关闭按钮，用于关闭/关闭该区域。（关闭1、关闭2、关闭3…）

我想归档以下内容：

if(close1.isPressed){
function invisall(1);
}

/*
 * instead of writing
 * if(close1.isPressed){
 * playbutton1._visible=false;
 * mutebutton1._visible=false;
 * }else if(close2.isPressed){
 * playbutton2._visible=false;
 * mutebutton2._visible=false;
 * etc. resulting in an enormous block.

 * the interesting part. buttonNr gets added via String to become a real buttonname(eg
 * playbutton1 as mentioned above).*/

function invisall(int buttonNr){
String newPlayButtonObjectName="playbutton"+buttonNr;
newPlayButtonObjectName._visible=false;

String newMuteButton="mutebutton"+buttonNr;
newMuteButton._visible=false;
}

this should do the trick via dynamic Nr at the end of each default button(eg
playbutton)
but ofc
"playbutton1"._visible=false;
doesnt work because playbutton1 is still a String.
how can i take the String as a Buttonname/ButtonObject?
do i need to write an new function? this would destroy the purpose of less code.

也许你喜欢这个主意。现在我将把这个区域分割成我放在舞台上的框架。这应该会有帮助

干杯

我希望这就是你想要的

function invisall(int buttonNr){
  this["playbutton"+buttonNr]._visible=false;
  this["mutebutton"+buttonNr]._visible=false;
}
