how to use jsx script in adobe Photoshop

Question

I found this piece of script offer by a solution on exactly what I try to do here. But I have no idea and can find no related info about this jsx script. I wonder where should I put it or use it in Adobe Photoshop CS6? I tried to use the script with Script->browse and double click on the file named script.jsx where I pasted the code below for export each layer into a file that has SAME background layer applied instead of the default transparent background. However, after I used it, nothing really happened and no error pop up. So I am not sure if anything I have done is not correct.

// variables
var destination = "C:/Users/...../"
var doc = app.activeDocument;
var artlayers = new Array();

// jpeg options
var options = new ExportOptionsSaveForWeb();
options.quality = 80;
options.format = SaveDocumentType.JPEG; 

// loop through all layers
var x = 0;
var a = 0;
while (x < doc.layers.length) {
    // check if the layer is a item
    if (doc.layers[x].kind == LayerKind.NORMAL) {
        // add to array
        artlayers[a] = x;
        a++;
    }
    x++;
}

var x = 0;
var a = 0;

for  (x=0; x < artlayers.length; x++)

{
doc.layers[artlayers[x]].visible = true;
// export as jpeg
try { doc.backgroundLayer.visible = true; } catch (e) {}
file = new File(destination + doc.layers[artlayers[x]].name +".jpg");
doc.exportDocument(file, ExportType.SAVEFORWEB, options); 
doc.layers[artlayers[x]].visible = false;
}

Thanks!

The script does work if you mess around with it a bit. And yes, joojaa is correct, it is a JSX.

Line 2 needs to be changed to an actual destination using slashes instead of backslashes, plus a semicolon at the end. I.e.,

 var destination = "C:/Users/USERNAME/FOLDER/";

You could also alter line 9 to

 options.quality = 100;

if you aren't actually saving for web and want to retain as much of the file's original quality as you can since this script is turning your PSD into a bunch of JPGs instead of PNGs.

I think you'll have to use the Browse function to utilize the script. PS doesn't seem to recognize its existence if you put it into Presets\Scripts.

That's as far as I can take it. I'm not a coder.
