取消选择所有在Finder使用JavaScript的自动化

Question

在使用JavaScript实现自动化时，我发现自己无法用AppleScript做一些非常简单的事情。（令人震惊，我知道。）

这个AppleScript：

tell application "Finder" to set selection to {}

清除Finder中的选择。

我只是不知道如何在JXA中实现同样的功能。

这是我尝试过的：

var finder = Application("Finder")
finder.includeStandardAdditions = true
  //this selects files in the front window...
finder.select( [...array of file paths...] )
  //so you'd think this might work to deselect all...
finder.select( [] )
  //...but it doesn't do anything

//then I tried each of these in turn...

finder.select( null )
  //Error -10010: Handler can't handle objects of this class.

finder.selection = null
  //Error -10010: Handler can't handle objects of this class.

finder.selection = []
  //Script Editor crashes

//...but none were successful

有什么建议吗？

（macOS Sierra，脚本编辑器2.9）

Answer 1

这是另一个你可以更好地考虑的“工作”。这将通过do shell通过JXA调用的osascript发送脚本的AppleScript版本（诀窍当然是正确地获取转义字符）：

var app = Application.currentApplication();
app.includeStandardAdditions = true;

app.doShellScript('osascript -e "tell application \\"Finder\\" to set selection to {}"');

------------原始答案-------------

好吧，我很确定我应该为这个答案道歉，但是，好吧，它确实有效，通过一个奇怪的工作环境，因为在玩了几个小时后，我无法得到一个更优雅的解决方案。谁知道呢，也许你会觉得这很优雅。我几乎做到了。或者也许有人会加入一个更好的。而且，我只是在脚本编辑器中处理过这个问题。[编辑]哦，还有，我还在10.10.5上

//this allows use of JXA version of do shell script later
var app = Application.currentApplication();

app.includeStandardAdditions = true;
var thefinder = Application("Finder");
//Would advise using if/then here to check if there's at least one window, like:
//    if (thefinder.windows.length != 0) {

//gets front window (where selection is, always)
var fWin = thefinder.windows[0];

//gets the "target", which is the folder ref
var fWinTarget = fWin.target();

//gets the url of the target
var winU = fWinTarget.url();

//makes that a path
var winUPath = Path(winU);

//closes the original finder window (ref)
fWin.close();

//opens it up again! no more selection!
app.doShellScript("open " + winU);
