我有一个脚本（我没写）其中有一个app.addEventListener('afterOpen', addVariables);事件（addVariables是该函数的名称）。
我将它改为app.addEventListener('afterSave', addVariables);，除了它正在创建一个“永无止境”的循环之外，它的工作原理我想要它。
基本上发生的事情是脚本提取用户名（即：Tia）并将其作为可变文本添加到InDesign CC中的粘贴板上。使用“afterOpen”命令，只要我打开文档，名称就会更新;因为我想知道谁最后保存文件，而不是最后一次打开文件的人（这将永远是我），这打败了剧本的目的。该脚本与“afterSave”命令一起正常工作，因为它显示了上次保存它的人的姓名;但是，我现在已经创建了一个新问题，即每当有人试图保存文档时脚本都会循环*。
所以，我的问题是这样的：我可以告诉eventListener每个文档只运行一次吗？
我对javascript不熟悉 - 我对applecript有一个公平的理解。
感谢您的帮助！
iMac运行osx 10.8.4•Adobe InDesign CC•使用Adobe ExtendScipt Toolkit编辑
*它循环，因为一旦有人保存文档，脚本就会运行并更改文本变量，InDesign（正确地）将其注释为对文档的更改。所以现在文档被标记为“未保存”（文档名称旁边有一个星号）。如果我按命令+ s再次保存它以“清除”星号，那么eventListener会选择afterSave命令并再次更新文档，然后InDesign会将其作为更改进行选择并将其标记为未保存...所以你可以看看我的意思是它循环。您可以告诉文档关闭（命令+ w）并告诉它在关闭之前保存，然后关闭。但是，我更喜欢只保存文档一次，变量文本更新，然后如果对该文档进行任何进一步更改仍然打开，脚本将不会再次运行。显然，我希望脚本在每个新文档上运行一次。

您可以通过跟踪脚本是否更新了特定文档的用户名来解决此问题。如果我们已经更新了它，那么在我们再次更新之前停止。否则，请继续进行更新。
您的JavaScript将如下所示：
#targetengine "session"
(function(){
// Keep track of the files where we've updated
// the user's name onto the pasteboard.
var isUserNameUpdated = {};
app.addEventListener('afterSave', function(theEvent) {
var filename = theEvent.fullName;
if (isUserNameUpdated[filename] === true) {
return;
}
isUserNameUpdated[filename] = true;
// Put the rest of your code here
});
app.addEventListener('afterOpen', function(theEvent) {
// afterOpen fires twice: once when the document opens
// and once when the window loads. Only the first event
// has the fullName property. So don't run the second time,
// to avoid causing an error.
//
// See: http://forums.adobe.com/message/5410190
if (theEvent.target.constructor.name !== 'Document') {
return;
}
// If we've previously saved the file, closed it,
// then opened it again, then forget that we had
// saved it previously.
var filename = theEvent.properties.fullName;
isUserNameUpdated[filename] = false;
});
})();

问题确实是每个保存操作都会触发侦听器，从而导致需要无限保存的未保存文档。 解决方案是禁用侦听器，以便您可以在不触发事件的情况下强制保存并在之后启用它。

答案 2 :(得分：0)
至少在Applescript中，可以选择让事件监听器对beforeSave 上的作出反应：
tell application "Adobe InDesign CC 2017"
make event listener with properties {event type:"beforeSave", handler:myHandler}
end tell
这应该可以解决问题。
