使用JavaScript for Automation取消选择Finder中的全部

Question

使用JavaScript进行自动化时，发现自己无法在AppleScript中执行非常简单的操作。 （令人震惊的，我知道。）

这个的AppleScript：

tell application "Finder" to set selection to {} 

清除在Finder中选择。

我只是无法弄清楚如何在JXA中做同样的事情。

这是我已经试过：

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？

[编辑]这里的另一种 “变通”，你可能会考虑更好。 这将通过osascript脚本的AppleScript的版本，称为经由JXA（把戏当然是拿到转义字符右）做外壳：

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

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

------------原来的回答-------------

好吧，我很确定我应该为这个答案道歉，但是，好吧，它确实工作，通过一个奇怪的解决办法，因为我可以在玩了几个小时后没有得到更优雅的解决方案。谁知道，也许你会发现这个优雅。我几乎。或者，也许有人会用更好的一个加入。另外，我只在脚本编辑器中一直搞这个。 [编辑]哦，还有，我还在10.10.5

//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);
