隱藏部分

Question

我只是試圖讓一個javascript自動爲Photoshop的過程，但我不希望這些零件在我的歷史顯示，一旦我做了。怎麼做？我的意思是並非所有的歷史記錄都應該清除。只有由腳本執行的那些。

謝謝

您無法通過腳本清除最近的文件列表。你也不能通過腳本刪除它recentFiles是隻讀的。

但是，您可以使最近的文件的副本，畢竟你的處理負載返回該列表（按照相反的順序），所以最近的文件列表是完全一樣的，你發現了它。

// recentFiles.length = 0; // doesn't work 


// get only existing recent files 
var myRecentItems = []; 
var s= ""; 
var len = recentFiles.length -1; 
var myTempDirectoryName = "c:\\temp"; 


for (var i = 0; i < recentFiles.length; i++) 
{ 
    var r = recentFiles[i]; 
    if (r.exists) 
    { 
     // alert(r + " exists!"); 
     myRecentItems.push(r); 
     s+= r + "\n"; 
    } 
} 

alert(myRecentItems.length); 

// set to zero 
set_recent_file_length(0); 

// DO STUFF HERE 
// or in this case create small images 
// with random names to pad out the recent files list 

// create new images 
for (var i = 0; i < myRecentItems.length; i++) 
{ 
    var n = get_random_string(8) + ".psd"; 
    create_new_document(10,10, 72, n); 
    // Set savePath and fileName to source path 
    var PSDfile = myTempDirectoryName + "\\" + n; 
    save_psd(PSDfile); 
} 

// END DO STUFF 


// Load the lrecent files list as we found it 
// get the old images back 
for (var i = len; i >= 0; i--) 
{ 
    var r = recentFiles[i]; 
    // open the files in reverse order 
    open_image(r); 
    //close that document without saving 
    app.activeDocument.close(SaveOptions.DONOTSAVECHANGES); 
} 

set_recent_file_length(len);
