How do I pause/resume in Photoshop with a JS code script?

I'm currently trying to automate a certain task in Photoshop (the latest version) with a JS code script. The each process is that 1. load an image -> 2. do something -> 3. implement an action -> 4. save the image -> 5. repeat this. Pretty simple, right? Cut to the chase, it's my code snippet below.
var opts;
opts = new ExportOptionsSaveForWeb();
opts.format = SaveDocumentType.PNG;
opts.PNG8 = false;
for(var i = 1; i < 6; i ++){
var filename = '/Users/abcde/Desktop/ap/' + i.toString() + '.PNG';
var file = File(filename);
var document = app.open(file);
// do something in Photoshop manually !!
app.doAction('bbbb', 'aaaa');
var savename = '/Users/abcde/Desktop/ap_save/' + i.toString() + '.PNG';
var savefile = new File(savename)
app.activeDocument.exportDocument(savefile, ExportType.SAVEFORWEB, opts);
}
So, my question is how do I pause the program when it loaded an image and do something, and get an input key like 'w' and resume the entire process again?
With my question, the code snippet is going to be like below
var opts;
opts = new ExportOptionsSaveForWeb();
opts.format = SaveDocumentType.PNG;
opts.PNG8 = false;
for(var i = 1; i < 6; i ++){
var filename = '/Users/abcde/Desktop/ap/' + i.toString() + '.PNG';
var file = File(filename);
var document = app.open(file);
// pause this code script (which type of code can I put in here?)
// do something(I'm going to do something manually in the Photoshpp when this script's been paused, this part doesn't has to be written in code)
// resume when it gets a key input(I want to type 'w' when that something task has been done, again.. which type of code function can I put?)
app.doAction('bbbb', 'aaaa');
var savename = '/Users/abcde/Desktop/ap_save/' + i.toString() + '.PNG';
var savefile = new File(savename)
app.activeDocument.exportDocument(savefile, ExportType.SAVEFORWEB, opts);
}
Please help me.
If either it's impossible to build or I need to clarify this question more let me know too.
Thanks.

I would restructure the script to run the export first (in case there is already a file open and then open the next document. Then, when the script is finished, the user can do something with the open document in Photoshop. Once they are done with that, they run the script again.
This needs a bit of extra checking if there is a document already open and also if there are any files left to handle. But it would basically look like this:
// set export options
var opts;
opts = new ExportOptionsSaveForWeb();
opts.format = SaveDocumentType.PNG;
opts.PNG8 = false;
// find out, which destination files already exists, to know which new one to open
// increase i until it finds an index that does not exist yet
var i = 1;
while( File('/Users/abcde/Desktop/ap_save/' + i.toString() + '.PNG').exists ) {
i++;
}
// if a document is already open, run the action on it and export it
if(app.documents.length) {
app.doAction('bbbb', 'aaaa');
var savename = '/Users/abcde/Desktop/ap_save/' + i.toString() + '.PNG';
var savefile = new File(savename)
app.activeDocument.exportDocument(savefile, ExportType.SAVEFORWEB, opts);
app.activeDocument.close();
// increase i once more to jump to the next file
i++;
}
// try to open a new source file, if there is one left
var srcFile = File('/Users/abcde/Desktop/ap/' + i.toString() + '.PNG)'
if(!srcFile.exists) {
// no further source file does exist, exit the script
exit();
}
var document = app.open(file);
// script ends here and the user can do stuff
// and then use a hot key to run the script again

Scraping table from website, with javascript:subOpen href link

I would like to scrape for each link on this page the page details page behind.
I can get all informations on this page: PAGE
However, I would like to get all info's on the details page, but the href link looks like that, for example:
href="javascript:subOpen('9ca8ed0fae15d43dc1257e7300345b99')"
Here is my sample spreadsheet using the ImportHTML function to get the general overview.
Google Spreadsheet
Any suggestions how to get the details pages?
UPDATE
I implemented the method the following:
function doGet(e){
var base = 'http://www.ediktsdatei.justiz.gv.at/edikte/ex/exedi3.nsf/'
var feed = UrlFetchApp.fetch(base + 'suche?OpenForm&subf=e&query=%28%5BVKat%5D%3DEH%20%7C%20%5BVKat%5D%3DZH%20%7C%20%5BVKat%5D%3DMH%20%7C%20%5BVKat%5D%3DMW%20%7C%20%5BVKat%5D%3DMSH%20%7C%20%5BVKat%5D%3DGGH%20%7C%20%5BVKat%5D%3DRH%20%7C%20%5BVKat%5D%3DHAN%20%7C%20%5BVKat%5D%3DWE%20%7C%20%5BVKat%5D%3DEW%20%7C%20%5BVKat%5D%3DMAI%20%7C%20%5BVKat%5D%3DDTW%20%7C%20%5BVKat%5D%3DDGW%20%7C%20%5BVKat%5D%3DGA%20%7C%20%5BVKat%5D%3DGW%20%7C%20%5BVKat%5D%3DUL%20%7C%20%5BVKat%5D%3DBBL%20%7C%20%5BVKat%5D%3DLF%20%7C%20%5BVKat%5D%3DGL%20%7C%20%5BVKat%5D%3DSE%20%7C%20%5BVKat%5D%3DSO%29%20AND%20%5BBL%5D%3D0').getContentText();
var d = document.createElement('div'); //assuming you can do this
d.innerHTML = feed;//make the text a dom structure
var arr = d.getElementsByTagName('a') //iterate over the page links
var response = "";
for(var i = 0;i<arr.length;i++){
var atr = arr[i].getAttribute('onclick');
if(atr) atr = atr.match(/subOpen\((.*?)\)/) //if onclick calls subOpen
if(atr && atr.length > 1){ //get the id
var detail = UrlFetchApp.fetch(base + '0/'+atr[1]).getContentText();
response += detail//process the relevant part of the content and append to the reposnse text
}
}
return ContentService.createTextOutput(response);
}
However, I get an error when running the method:
ReferenceError: "document" is not defined. (line 6, file "")
What is the document an object of?
I have update the Google Spreadsheet with a webapp.

You can use Firebug in order to inspect the page contents and javascript. For instance you can find that subOpen is actually an alias to subOpenXML declared in xmlhttp01.js.
function subOpenXML(unid) {/*open found doc from search view*/
if (waiting) return alert(bittewar);
var wState = dynDoc.getElementById('windowState');
wState.value = 'H';/*httpreq pending*/
var last = '';
if (unid==docLinks[0]) {last += '&f=1'; thisdocnum = 1;}
if (unid==docLinks[docLinks.length-1]) {
last += '&l=1';
thisdocnum = docLinks.length;
} else {
for (var i=1;i<docLinks.length-1;i++)
if (unid==docLinks[i]) {thisdocnum = i+1; break;}
}
var url = unid + html_delim + 'OpenDocument'+last + '&bm=2';
httpreq.open('GET', // &rand=' + Math.random();
/*'/edikte/test/ex/exedi31.nsf/0/'+*/ '0/'+url, true);
httpreq.onreadystatechange=onreadystatechange;
// httpreq.setRequestHeader('Accept','text/xml');
httpreq.send(null);
waiting = true;
title2src = firstTextChild(dynDoc.getElementById('title2')).nodeValue;
}
So, after copying the function source and modifying it in firebug's Console tab to add a console.log(url) before the http call, like this:
var url = unid + html_delim + 'OpenDocument'+last + '&bm=2';
console.log(url)
httpreq.open('GET', // &rand=' + Math.random();
/*'/edikte/test/ex/exedi31.nsf/0/'+*/ '0/'+url, true);
You can execute the function declaration in firebug's Console tab and overwrite subOpen with the modified source.
Clickin in the link then will show that the invoked url is composed of the id passed as parameter to subOpen prefixed by '0/', so in the example you posted it would be a GET to:
http://www.ediktsdatei.justiz.gv.at/edikte/ex/exedi3.nsf/0/1fd2313c2e0095bfc1257e49004170ca?OpenDocument&f=1&bm=2
You could also verify this by opening the Network tab in firebug and clicking the link.
Therefore, in order to scrape the details page you'd need to
Parse the id passed to subOpen
Make a GET call to '0/'
Parse the request response
Looking the request response in firebug's Network Tab shows that probably you'll need to do similar parsing to actually get the showed contents, but I haven't looked deep into it.
UPDATE
The importHTML function is not suitable for the kind of scraping you want. Google's HTML or Content Services are better suited for this. You'll need to create a web app and implement the doGet function:
function doGet(e){
var base = 'http://www.ediktsdatei.justiz.gv.at/edikte/ex/exedi3.nsf/'
var feed = UrlFetchApp.fetch(base + 'suche?OpenForm&subf=e&query=%28%5BVKat%5D%3DEH%20%7C%20%5BVKat%5D%3DZH%20%7C%20%5BVKat%5D%3DMH%20%7C%20%5BVKat%5D%3DMW%20%7C%20%5BVKat%5D%3DMSH%20%7C%20%5BVKat%5D%3DGGH%20%7C%20%5BVKat%5D%3DRH%20%7C%20%5BVKat%5D%3DHAN%20%7C%20%5BVKat%5D%3DWE%20%7C%20%5BVKat%5D%3DEW%20%7C%20%5BVKat%5D%3DMAI%20%7C%20%5BVKat%5D%3DDTW%20%7C%20%5BVKat%5D%3DDGW%20%7C%20%5BVKat%5D%3DGA%20%7C%20%5BVKat%5D%3DGW%20%7C%20%5BVKat%5D%3DUL%20%7C%20%5BVKat%5D%3DBBL%20%7C%20%5BVKat%5D%3DLF%20%7C%20%5BVKat%5D%3DGL%20%7C%20%5BVKat%5D%3DSE%20%7C%20%5BVKat%5D%3DSO%29%20AND%20%5BBL%5D%3D0').getContentText();
var response = "";
var match = feed.match(/subOpen\('.*?'\)/g)
if(match){
for(var i = 0; i < match.length;i++){
var m = match[i].match(/\('(.*)'\)/);
if(m && m.length > 1){
var detailText = UrlFetchApp.fetch(base + '0/'+m[1]);
response += //dosomething with detail text
//and concatenate in the response
}
}
}
return ContentService.createTextOutput(response);

Get String Value of Blob Passed to e.parameter in Apps Script

I'm using this code to get a blob passed to a function:
function submit(e){
var arrayBlob = e.parameter.arrayBlob;
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
This is the error I get:
Execution failed: TypeError: Can not find getDataAsString function in
the Blob object.'arrayBlob'
How do I get the string value of this blob?
Here is my code:
function showList(folderID) {
var folder = DocsList.getFolderById(folderID);
var files = folder.getFiles();
var arrayList = [];
for (var file in files) {
file = files[file];
var thesesName = file.getName();
var thesesId = file.getId();
var thesesDoc = DocumentApp.openById(thesesId);
for (var child = 0; child < thesesDoc.getNumChildren(); child++){
var thesesFirstParagraph = thesesDoc.getChild(child);
var thesesType = thesesFirstParagraph.getText();
if (thesesType != ''){
var newArray = [thesesName, thesesType, thesesId];
arrayList.push(newArray);
break;
}
}
}
arrayList.sort();
var result = userProperties.getProperty('savedArray');
arrayList = JSON.stringify(arrayList);
var arrayBlob = Utilities.newBlob(arrayList);
Logger.log("arrayBlob #1 = " + arrayBlob.getDataAsString()); // Here it`s OK
var mydoc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setWidth(550).setHeight(450);
var panel = app.createVerticalPanel()
.setId('panel');
panel.add(app.createHidden('arrayBlob', arrayBlob));
var label = app.createLabel("Selecione os itens desejados").setStyleAttribute("fontSize", 18);
app.add(label);
arrayList = JSON.parse(arrayList);
panel.add(app.createHidden('checkbox_total', arrayList.length));
for(var i = 0; i < arrayList.length; i++){
var checkbox = app.createCheckBox().setName('checkbox_isChecked_'+i).setText(arrayList[i][0]);
Logger.log("arrayList[i][0] = " + arrayList[i][0]);
Logger.log("arrayList[i] ====> " + arrayList[i]);
panel.add(checkbox);
}
var handler = app.createServerHandler('submit').addCallbackElement(panel);
panel.add(app.createButton('Submit', handler));
var scroll = app.createScrollPanel().setPixelSize(500, 400);
scroll.add(panel);
app.add(scroll);
mydoc.show(app);
}
function submit(e){
var arrayBlob = e.parameter.arrayBlob;
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
// Continues...
}
I'd like the solution worked with more than one user simultaneous using the script.

Update:
Add a global variable OUTSIDE of any function:
var arrayBlob = Utilities.newBlob("dummy data");
function showList(folderID) {
Code here ....
};
Check that the code has access to the blob:
function submit(e){
Logger.log("arrayBlob.getDataAsString(): " + arrayBlob.getDataAsString());
//More Code . . .
}
This solution eliminates the need of embedding a hidden element in the dialog box with a value of the blob.
You won't need this line:
panel.add(app.createHidden('arrayBlob', arrayBlob));
There are other changes I'd make to the code, but I simply want to show the main issue.
Old Info:
In the function showList(), the method getDataAsString() works on the blob named arrayBlob.
Logger.log("arrayBlob #1 = " + arrayBlob.getDataAsString()); // Here it`s OK
In the function, submit(), the same method does not work.
var arrayBlob = e.parameter.arrayBlob;
In the function showList(), the code is assigning a newBlob to the variable arrayBlob. So arrayBlob is available to have the getDataAsString() method used on it.
var arrayBlob = Utilities.newBlob(arrayList);
In the function, submit(), you are trying to pass the arrayBlob blob variable into the submit() function, and reference it with e.parameter.
If you put a Logger.log() statement in the submit() function.
function submit(e){
Logger.log('e: ' + e);
Logger.log('e.parameter` + e.parameter);
var arrayBlob = e.parameter.arrayBlob;
Those Logger.log statements should show something in them. If there is nothing in e.parameter, then there is nothing for the .getDataAsString() to work on.
It looks like you are putting the arrayBlob into a hidden panel.
panel.add(app.createHidden('arrayBlob', arrayBlob));
But when the object is getting passed to the submit(e) function, the arrayBlob might not be getting put into that object.
So, what I'm saying is, the:
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
Line may be perfectly good, but there is no arrayBlob there to work on. This hasn't fixed your problem, but do you think I'm understanding part of what is going on?

I'm not sure why you are using Blob's here at all, you could simply work with JSON instead.
However, if you have a reason to use Blobs, you can pass the JSON data through your form and create the Blob in your handler, as the modified code below does:
function showList(folderID) {
var folder = DocsList.getFolderById(folderID);
var files = folder.getFiles();
var arrayList = [];
for (var file in files) {
file = files[file];
var thesesName = file.getName();
var thesesId = file.getId();
var thesesDoc = DocumentApp.openById(thesesId);
for (var child = 0; child < thesesDoc.getNumChildren(); child++){
var thesesFirstParagraph = thesesDoc.getChild(child);
var thesesType = thesesFirstParagraph.getText();
if (thesesType != ''){
var newArray = [thesesName, thesesType, thesesId];
arrayList.push(newArray);
break;
}
}
}
arrayList.sort();
var result = UserProperties.getProperty('savedArray');
//get JSON data pass through form.
var arrayBlob = JSON.stringify(arrayList);
var mydoc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setWidth(550).setHeight(450);
var panel = app.createVerticalPanel()
.setId('panel');
//include JSON Data in the form.
panel.add(app.createHidden('arrayBlob', arrayBlob));
var label = app.createLabel("Selecione os itens desejados").setStyleAttribute("fontSize", 18);
app.add(label);
panel.add(app.createHidden('checkbox_total', arrayList.length));
for(var i = 0; i < arrayList.length; i++){
var checkbox = app.createCheckBox().setName('checkbox_isChecked_'+i).setText(arrayList[i][0]);
Logger.log("arrayList[i][0] = " + arrayList[i][0]);
Logger.log("arrayList[i] ====> " + arrayList[i]);
panel.add(checkbox);
}
var handler = app.createServerHandler('submit').addCallbackElement(panel);
panel.add(app.createButton('Submit', handler));
var scroll = app.createScrollPanel().setPixelSize(500, 400);
scroll.add(panel);
app.add(scroll);
mydoc.show(app);
}
function submit(e){
var arrayBlob = Utilities.newBlob(e.parameter.arrayBlob);
Logger.log("arrayBlob #2 = " + arrayBlob.getDataAsString());
// Continues...
}
In the method you were using originally, the Blob itself was never included in the form, you were simply passing the string "Blob" around.
This is because the function createHidden(name, value); expects two strings as parameters, so it calls ".toString()" on the arrayBlob object, which returns the string "Blob".

Titanium passing data to createHTTPClient

I have a loop that parses a JSON from a request, and generates a table.
Now the images on that table need to be downloaded, which is why i use a createHTTPClient request to get the images.
The issue is, i want to update the rows live as the image is downloaded.
But due to createHTTPClient being async, it fails to do that... It always gets the last row...
How do i pass the current row to the onload event?
My code goes something like:
onload: function(e) {
asjson = JSON.parse(this.responseText);
for (var i=0;i<asjson.objects.length;i++){
var fname = asjson['objects'][i].photos[0].photo;
var file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, fname);
var row = Ti.UI.createTableViewRow({
title : asjson['objects'][i].name,
hasChild : true,
color: 'white',
albumid : asjson['objects'][i].id,
songid : asjson['objects'][i].id,
id : asjson['objects'][i].staff[0].id,
idtype : 1
});
if (!file.exists()) {
var c = Titanium.Network.createHTTPClient();
c.setTimeout(10000);
c.open('GET','http://localhost:8000/' + fname);
c.file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, fname);
c.onload = function(e){
file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, fname);
row.leftImage = f1 = Titanium.Filesystem.applicationDataDirectory + '/' + fname;
};
c.send();
}
}

So you have a couple of different options here. You could create all the rows ahead of time. Then once the images are loaded, loop over the table looking for the correct row and setting the images then.
However I would recommend the following approach. The JSLint website has a good explanation why adding functions is a bad idea inside of a loop. JSLint
onload: function(e){
var asJson = JSON.parse(this.responseText);
for(var i = 0, length = asJson.objects.length; i < length; i++){
var fileName = asjson.objects[i].photos[0].photo;
var file = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, fileName);
var fileId = asJson.objects[i].id;
var row = Ti.UI.createTableViewRow({
title : asJson.objects[i].name,
hasChild : true,
color: 'white',
albumid : fileId,
songid : fileId,
id : asJson.objects[i].staff[0].id,
idtype : 1
});
if(!file.exists()){
var c = Titanium.Network.createHTTPClient();
c.setTimeout(10000);
c.open('GET','http://localhost:8000/' + fileName);
c.file = Titanium.Filesystem.getFile(Titanium.FileSystem.applicationDataDirectory,fileName);
c.onload = rowImageOnLoadHandler(row,fileName);
c.send();
}
}
}
Notice the rowOnLoadHandler function. This function will allow you to keep a reference to the row the HTTPClient request is running for.
function rowImageOnLoadHandler(row,fileName){
return function(){
row.leftImage = Titanium.Filesystem.applicationDataDirectory + '/' + fileName;
};
}

So i got creative and came up with another answer.
Basically, i append the row number to the url:
c.open('GET','http://localhost:8000/' + fileName + '?i=' + i);
Then, i can access the location property by using this.location.
From there on, it's a matter of updating the row with the data...

createFile() in google Apps Script is not functioning properly

I am trying to create a file. It works fine when I run the following code segment from the debugger in apps script. However, when I run it real time from the spreadsheet, it says I do not have permission to call createfile. Everything that is logged is identical. The issue is not I do not have authority as I am the only one in the spreadsheet and am the owner. The purpose of the CSV is to move it from my google drive into data for BigQuery
function saveAsCSV(row) { //Doc to Csv
//row = 3; //when this is uncommented and ran from the debugger, it works.

}
}

You mention in your comment on my answer that you are using onEdit to trigger the script. Since this is a Simple Trigger, your current approach will not work. When you use simple triggers to run an Apps Script, it runs in a sandbox with reduced permissions.
See: https://developers.google.com/apps-script/guides/triggers/#restrictions
The best I can recommend is create a custom menu option with a UI popup asking for the row number to export. If the code is triggered from a menu by the user, it runs with full permission to access that users account.
Depending on your use-case, a scheduled trigger might work too. It could run every 10 minutes or every Hour and export any changes to the spreadsheet. In this case the Apps Script runs as you, with permission to access your account, and the resulting CSV would be created on your drive.
