Photoshop Extendscript - 文件被锁定 - 无法保存

Question

I can't save my file with javascript. The error when trying to save the file via my script is:

Could not save a copy as "..." because the file is locked, you do not have necessary permissions, or another program is using the file. Use the "properties" command in the Windows Explorer to unlock the file.

If I press ok, my script tells me "User abort".

I already successfully wrote a few.jsx with the extendscript toolkit to automate photoshop but this is the first time reading.psd paths from a csv list and opening them in photoshop.

I think the problem is because "var docRef = app.activeDocument;" is created in my savePng function while still in the loop reading my.csv

Here is a part of my code where I am looping all my photoshop files and trying to save them as.png

I do a few functions here to process my automation.

for (var i = 0; i <= lineslength - 2; i++){
    if(typeof lines[i] !== "undefined")
    {
        app.open(new File(lines[i]));
        var docname = app.activeDocument;
        var filenamelong = docname.name
        var filename = filenamelong.substring(4, filenamelong.length - 4);
        clickonlayer()
        createlayer()
        isolate()
        maskinput("image_mask")
        try {
            maskadd("image2_mask")
            maskadd("image3_mask")
            maskadd("image4_mask")
        }
        catch(error){
        }
        setcolor()
        deselect()
        savePng(filename)
        activeDocument.close(SaveOptions.DONOTSAVECHANGES);
        filenew.writeln(lines[i] + "        EXPORTED")
    } 
}

Here is my savePng function:

function savePng(psdname) {
var docRef = app.activeDocument;
var exppath = "C:/Users/Jeremy/Documents/export";
var filepath = psdname + '.png'
var file = new File(filepath);
var opts = new PNGSaveOptions();
docRef.saveAs(file, opts, true);
}

Usually in my photoshop scripts I open a file and create the app.activeDocument variable but this time it needs to be created after the file will be opened via the script.

I appreciate any help.

Answer 1

var filepath = psdname + '.png'

I belive there should be

var filepath = exppath + "/" + psdname + '.png'
