如何用Photoshop JavaScript将文本写入到文本文件中?

I took a look at Photoshop CS5 Scripting Guide and Photoshop CS5 JavaScript Reference, but I couldn't find out a method to write text to a plain text file. Is there any way to do that?

我查看了Photoshop CS5脚本指南和Photoshop CS5 JavaScript参考，但是我找不到一个方法将文本写入纯文本文件。有什么办法吗?

I want to record the value of bounds of each layer object in a document.

我想记录文档中每个层对象的界限值。

Any hint?

有提示吗?

File system access is documented in Adobe's JavaScript Tools Guide (PDF).

文件系统访问被记录在Adobe的JavaScript工具指南(PDF)中。

Download the PDF file and check out the "File System Access" section.

下载PDF文件并查看“文件系统访问”部分。

This works for me, saves text with the same name as original document, but with extension txt:

这对我来说是可行的，保存与原始文档同名的文本，但是扩展名txt:

function saveTxt(txt)
{
    var Name = app.activeDocument.name.replace(/\.[^\.]+$/, '');
    var Ext = decodeURI(app.activeDocument.name).replace(/^.*\./,'');
    if (Ext.toLowerCase() != 'psd')
        return;

    var Path = app.activeDocument.path;
    var saveFile = File(Path + "/" + Name +".txt");

    if(saveFile.exists)
        saveFile.remove();

    saveFile.encoding = "UTF8";
    saveFile.open("e", "TEXT", "????");
    saveFile.writeln(txt);
    saveFile.close();
}

I don't know how it works, photoshop scripting is a huge mess, I just kept mixing together a few scripts that I found until it worked.

我不知道它是如何工作的，photoshop脚本是一个巨大的混乱，我只是不断地混合一些我发现的脚本，直到它起作用。

Also, if anyone needs this, here is a script that also saves active document as png image:

另外，如果有人需要这个，这里有一个脚本，它也可以将活动文档保存为png图像:

function savePng()
{
    var Name = app.activeDocument.name.replace(/\.[^\.]+$/, '');
    var Ext = decodeURI(app.activeDocument.name).replace(/^.*\./,'');
    if (Ext.toLowerCase() != 'psd')
        return;

    var Path = app.activeDocument.path;
    var saveFile = File(Path + "/" + Name +".png");

    if(saveFile.exists)
        saveFile.remove();

    var o = new ExportOptionsSaveForWeb();
        o.format = SaveDocumentType.PNG;
        o.PNG8 = false;
        o.transparency = true;
        o.interlaced = false;
        o.includeProfile = false;
    activeDocument.exportDocument(saveFile, ExportType.SAVEFORWEB, o);
}

I found the docs lacking but came up with this as a method to create and write to a new file in CS6:

我发现文档中缺少文档，但我将它作为创建和写入CS6中的新文件的方法:

var s = "My string data here";
var file = new File();
var fileNew = file.saveDlg("Save new file");
fileNew.open("w");
fileNew.write(s);
fileNew.close();

I have read the docs and combined best parts of psycho brm's and corrin_m's answer.
MY ANSWER ALSO CHECKS FOR ERRORS.

我读过《精神病人brm》和《corrin_m的答案》的文章，并将它们的精华部分结合在一起。我的回答也检查错误。

It is not necessary to delete file if it exists because opening with "w" will overwrite existing file it.

如果文件存在，则不需要删除文件，因为打开“w”会覆盖现有的文件。

/* =======================================================
 * Saves file as text. Overwrites old file if exists.
 * Returns empty string if no errors, otherwise error message.
 * =======================================================*/
function saveAsTextFile(filePath, content) {
    var saveFile = new File(filePath);

    saveFile.encoding = "UTF8";
    saveFile.open("w");
    if (saveFile.error != "")
        return saveFile.error;

    saveFile.write(content);
    if (saveFile.error != "")
        return saveFile.error;

    saveFile.close();
    if (saveFile.error != "")
        return saveFile.error;

    return "";
}

This is how I am using the function in my scripts

这就是我在脚本中使用函数的方式

error = saveAsTextFile(filePath, content);
if (error === "") {
  alert(filePath + " saved OK.");
}
else {
  alert("Error saving " + filePath + "\n" + error);
}

BTW I am keeping this in separate file called commom-code.jsx and I can include it with following line (single line comments are intentional).

顺便说一句，我把它保存在一个名为commom-code的单独文件中。jsx和我可以将它包含在以下行中(单行注释是有意的)。

// @include 'common-code.jsx'

Here's what you need: It's pretty basic. It'll loop over the layers (no layersets!!) and save out the layer name and the layer bounds for each layer.

这是你需要的:它是非常基本的。它将循环遍历各层(没有层集!!)并保存每个层的层名和层界限。

app.preferences.rulerUnits = Units.PIXELS;
var srcDoc = app.activeDocument;
var numOfLayers = srcDoc.layers.length;
var results = "";
var fileName = srcDoc.name;
var docName = fileName.substring(0,fileName.length -4)
var theFile = srcDoc.path + "/" + docName + ".txt";

for (var i = 0; i < numOfLayers  ; i++)
{
  var theLayer = srcDoc.layers[i];
  var lb = getLayerBounds(theLayer).toString();
  results += theLayer.name + ": " + lb + "\n";
}

writeTextFile(theFile, results)
alert(results);

function getLayerBounds(alayer)
{
  var x1 = parseFloat(alayer.bounds[0])
  var y1 = parseFloat(alayer.bounds[1])
  var x2 = parseFloat(alayer.bounds[2])
  var y2 = parseFloat(alayer.bounds[3])
  return [x1,y1,x2,y2]
}

function writeTextFile(afilename, output)
{
  var txtFile = new File(afilename);
  txtFile.open("w"); //
  txtFile.writeln(output);
  txtFile.close();
}
