Comparing JPG files with Photoshop Layers

Is it possible to compare filenames for a set of files that are imported as Photoshop layers ?
I have a folder of 50 jpg images which I have used in a PSD file.
Now I want to check whether all the JPG files are used or not ?
Is it possible to do so ?

As I've said, Photoshop scripting can help you achieve this by using File Objects and basic javascript knowledge. I've modified my old script as you've desired and now it should work well with any nested groups and images.
I highly encourage you to learn scripting and ask questions here wherever you feels confused.
Save below code as 'Script.jsx' and run it from 'File > Scripts > Browse'
Update 2 : Now it saves log.txt file too as per you requested. P.S. Learn from this script and tweak it to your desired result.
// Managing Document
var docs = app.documents;
// Progress Bar
var win = new Window("window{text:'Progress',bounds:[100,100,400,150],bar:Progressbar{bounds:[20,20,280,31] , value:0,maxvalue:100}};");
// assigning activeDocument
if (docs.length != 0) {
var docRef = app.activeDocument;
// Defining the folder
alert("You will be prompted for the folder containing your images.\n" +
"Files will be selected with a '.png'/'.jpg/.jpeg' on the end in the same folder.");
var folder = Folder.selectDialog();
if (!folder) {
exit;
}
var photoFiles = folder.getFiles(/\.(jpg|jpeg|png)$/i);
var matchFiles = [];
var photoFilesName = [];
//Searching for used images
var increment = parseFloat(0);
var divider = parseFloat(100/photoFiles.length);
win.show();
for (var i = 0; i < photoFiles.length; i++) {
increment = increment + divider;
var indexPhotoName = removeExtension(photoFiles[i].displayName);
photoFilesName.push(indexPhotoName);
var doc = activeDocument;
var curLayer;
goThroughLayers(doc, indexPhotoName);
}

if(!missFolder.exists){
missFolder.create();
}
for (var y = 0; y < photoFiles.length; y++) {
var photoTrimName = removeExtension(photoFiles[y].displayName);
for( var x = 0; x < missItems.length ; x++){
if(photoTrimName == missItems[x]){
photoFiles[y].copy(new File(missFolder+'/'+photoFiles[y].displayName));
}
}
};
win.close();
alert("You've missed total " + missItems.length + " files. Press OK to open folder containing missing files. Log report is generated wherever PSD is saved.");
var FileStr = "";
for(var m=0; m<missItems.length; m++){
FileStr = FileStr + '\n' + (m+1) + '. ' + missItems[m];
}
var str = "Your missed files are : " + FileStr;
saveTxt(str);
missFolder.execute();
} else {
win.close();
saveTxt('All Photos are used');
alert('All Photos are used');
}
} else {
alert('Open atleast one document');
}
function saveTxt(txt)
{
var Name = "LogReport_" + 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();
}

In Javascript, it is possible to get some information related to PSD file layers using PSD.js library

Jquery ajax send json

Javascript:
function add_content(count)
{
var result = {};
var row = new Array();
for (i = 0; i < count; i++)
{
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}
$.ajax({
url: "ajax-functions.php",
data: {json_data: JSON.stringify(row)},
type: 'post',
success: function (output) {
alert(output);
}
})
}
Php:
$img_desc = json_decode($_POST['json_data'],TRUE);
$count = count($img_desc);
echo 'count:'.$count;
print_r($img_desc);
I want to send json to from JS to PHP. This above code works well, but it send the last data of the for loop is set in all the objects.
How to fix it? Is this right way?
Thanks.

Push a new object on each round of the loop into to the array
for (var i = 0; i < count; i++) {
row.push({
"img_src": $("#img_" + i).attr('src'),
"desc": $("#desc_" + i).val()
});
}
fiddle

Move result declaration inside for:
var row = new Array();
for (i = 0; i < count; i++)
{
var result = {};
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}
or it can be done more elegantly:
var row = new Array();
var result;
for (i = 0; i < 10; i++)
{
result = row[ row.push({}) - 1 ];
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
}

You can make the keys of result array also dynamic
Since you are not making it dynmamic, its getting over ridden in the next loop
EDIT:
for (i = 0; i < count; i++)
{
var result = {};
result['img_src'] = $("#img_" + i).attr('src');
result['desc'] = $("#desc_" + i).val();
row.push(result);
}

Transfer data from php as json, then store it in global object

I have the following code:
PHP code:
$data = array();
$data[0]['name'] = "Kj";
$data[0]['age'] = 30;
$data[0]['country'] = "Italy";
$data[1]['name'] = "Dn";
$data[1]['age'] = 18;
$data[1]['country'] = "USA";
$data[2]['name'] = "Jo";
$data[2]['age'] = 22;
$data[2]['country'] = "Switzerland";
$data[3]['name'] = "Ro";
$data[3]['age'] = 34;
$data[3]['country'] = "UAE";
$data[4]['name'] = "Lc";
$data[4]['age'] = 13;
$data[4]['country'] = "UK";
echo json_encode($data);
Javascript code:
var jsonData = {};
$(document).ready(function () {
$.get('page.php', function (data) {
jsonData = jQuery.parseJSON(data);
});
});
for (var i = 0; i < jsonData.length; i++) {
$('ul').append("<li>" + jsonData[i].name + "</li>");
}
The problem is when put the for loop inside the $.get callback works fine like as the following.
$.get('page.php', function (data) {
jsonData = jQuery.parseJSON(data);
for (var i = 0; i < jsonData.length; i++) {
$('ul').append("<li>" + jsonData[i].name + "</li>");
}
});
But when put the for loop outside the $.get callback does not print out anything, but the data has been received successfully, but without print it.
Now, how can store the data that has been received in global variable to print it in anywhere ?

You should change your approach when you work with asynchronous operations (AJAX, timeouts). Something like this:
function GetData(callback) {
$.get('page.php', function (data) {
callback(jQuery.parseJSON(data));
});
}
GetData(function (data) {
for (var i = 0; i < data.length; i++) {
$('ul').append("<li>" + data[i].name + "</li>");
}
});

Your code already stores data in a global variable correctly.
Type jsonData into F12-javascript console and you will see it.
The question is rather about the control flow, what is the other event that will trigger usage of jsonData?

generate list of variables from a FOR loop

var select = [];
for (var i = 0; i < nameslots; i += 1) {
select[i] = this.value;
}
This is an extract of my code. I want to generate a list of variables (select1, select2, etc. depending on the length of nameslots in the for.
This doesn't seem to be working. How can I achieve this? If you require the full code I can post it.
EDIT: full code for this specific function.
//name and time slots
function gennametime() {
document.getElementById('slots').innerHTML = '';
var namelist = editnamebox.children, slotnameHtml = '', optionlist;
nameslots = document.getElementById('setpresentslots').value;
for (var f = 0; f < namelist.length; f += 1) {
slotnameHtml += '<option>'
+ namelist[f].children[0].value
+ '</option>';
};
var select = [];
for (var i = 0; i < nameslots; i += 1) {
var slotname = document.createElement('select'),
slottime = document.createElement('select'),
slotlist = document.createElement('li');
slotname.id = 'personname' + i;
slottime.id = 'persontime' + i;
slottime.className = 'persontime';
slotname.innerHTML = slotnameHtml;
slottime.innerHTML = '<optgroup><option value="1">00:01</option><option value="2">00:02</option><option value="3">00:03</option><option value="4">00:04</option><option value="5">00:05</option><option value="6">00:06</option><option value="7">00:07</option><option value="8">00:08</option><option value="9">00:09</option><option value="10">00:10</option><option value="15">00:15</option><option value="20">00:20</option><option value="25">00:25</option><option value="30">00:30</option><option value="35">00:35</option><option value="40">00:40</option><option value="45">00:45</option><option value="50">00:50</option><option value="55">00:55</option><option value="60">1:00</option><option value="75">1:15</option><option value="90">1:30</option><option value="105">1:45</option><option value="120">2:00</option></optgroup>';
slotlist.appendChild(slotname);
slotlist.appendChild(slottime);
document.getElementById('slots').appendChild(slotlist);
(function (slottime) {
slottime.addEventListener("change", function () {
select[i] = this.value;
});
})(slottime);
}
}

You'll have to close in the iterator as well in that IIFE
(function (slottime, j) {
slottime.addEventListener("change", function () {
select[j] = this.value;
});
})(slottime, i);
and it's only updated when the element actually change

The cool thing about JavaScript arrays is that you can add things to them after the fact.
var select = [];
for(var i = 0; i < nameSlots; i++) {
var newValue = this.value;
// Push appends the new value to the end of the array.
select.push(newValue);
}

passing page scraped data in the URL

In my Chrome extension, I'm trying to scrape information from the current tab (in content.js) and send it as parameter to the provided URL (background.js). It seems like I can scrape everything from the tab and append it to the URL except the values of input tags. Here's my code:
content.js:
var elements = new Array("form","h1","input","td","textarea","time","title","var");
//declare an array for found elements
var foundElements = new Array();
//declare an array for found ids
var foundIds = new Array();
//this counter is used to hold positions in the element array.
var elementCounter = 0;
//this counter is used to hold positions in the foundIds array
var idsCounter = 0;
//this counter is used to hold positions in the classCounter array.
var classCounter = 0;
//and we're going to output everything in a giantic string.
var output = "URL=" + document.URL;
//scrape the page for all elements
for (var i = 0; i < elements.length; i++)
{
var current = document.getElementsByTagName(elements[i]);
if(current.length>0)
{
for (var z=0; z<current.length; z++)
{
var inTxt = current[z].innerText;
output += "&" + elements[i] + "=" + inTxt;
}
elementCounter++;
//now that we have an array of a tag, check it for IDs and classes.
for (var y = 0; y<current.length; y++)
{
//check to see if the element has an id
if(current[y].id)
{
//these should be unique
var hit = false;
for (var x = 0; x<foundIds.length; x++)
{
if(foundIds[x]==current[y].id)
{
hit=true;
}
}
//if there was no hit...
if(!hit)
{
foundIds[idsCounter]=current[y].id;
idsCounter++;
var currVal = current[y].value;
output+="&" + current[y].id + "=" + currVal;
}
}
//now we pull the classes
var classes = current[y].classList;
if(classes.length>0)
{
for (var x = 0; x<classes.Length; x++)
{
var hit = false;
for (var z = 0; z<foundClasses.length; z++)
{
if(foundClasses[z]==classes[x])
{
hit=true;
}
}
//if there was not a hit
if(!hit)
{
foundClasses[classCounter]=classes[x];
classCounter++;
output+="&" + classes[x] + "=";
}
}
}
}
}
}
chrome.runtime.sendMessage({data: output});
background.js:
var output2;
chrome.extension.onMessage.addListener(function(request, sender, sendResponse) {
output2 = "text_input1=";
output2 += request.data;
});
chrome.browserAction.onClicked.addListener(function() {
chrome.tabs.create({url: "http://www.google.com?" + output2}, function(tab) {
chrome.tabs.executeScript(tab.id, {file: "content.js"}, function() {
sendMessage();
});
});
});
Does anyone know why the input tags values are passed as blank?

Because you're trying to get the input text by using current[z].innerText.
However, you have to use current[z].value for inputs.
