Creating an array from a script then alert the contents

I've created a script to create a new array called spots, here is the script:
main();
function main() {
var doc = app.activeDocument;
var selectedSwatches = doc.swatches.getSelected();
var pageNumber = 1;
var count = 0;
if (selectedSwatches.length > 0) {
var text = 'var spots = new Array(\n';
for (var i = 0; i < selectedSwatches.length; i++) {
var swatch = selectedSwatches[i]
var color = swatch.color;
// Spot
if (color.typename == "SpotColor") {
count++;
text += '"' + color.spot.name + '", ' + "\n";
color = color.spot.color;
if (count % 10 == 0)
pageNumber++;
}
}
var textend = ');';
var textArray = text + textend;
alert(textArray);
} else {
alert("No Swatches Selected.");
}
}
This script alerts the following:
var spots = new Array(
"Yellow 012 C",
"Bright Red C",
);
How do I now alert the contents of that array i.e. Yellow 012 C, Bright Red C
I have tried using:
alert(spots);
But I get the error undefined maybe because the array is created on the fly and its not placed in the script?
UPDATE:
As per the comments, I have edited the script adding:
var spots = [];
spots.push(color.spot)
alert(spots);
I now get the following error: undefined is not an object
Here's the full script
main();
function main() {
var doc = app.activeDocument;
var selectedSwatches = doc.swatches.getSelected();
var pageNumber = 1;
var count = 0;
if (selectedSwatches.length > 0) {
var text = 'var spots = new Array(\n';
for (var i = 0; i < selectedSwatches.length; i++) {
var swatch = selectedSwatches[i]
var color = swatch.color;
// Spot
if (color.typename == "SpotColor") {
count++;
text += '"' + color.spot.name + '", ' + "\n";
color = color.spot.color;
if (count % 10 == 0)
pageNumber++;
}
}
var textend = ');';
var textArray = text + textend;
var spots = [];
spots.push(color.spot)
alert(spots);
} else {
alert("No Swatches Selected.");
}
}

Try
function main() {
//var doc = app.activeDocument;
var selectedSwatches
= [{"color":{"spot":{"color":"#ff0000","name":"red"},"typename":"SpotColor"}}
,{"color":{"spot":{"color":"#000000","name":"black"},"typename":"SpotColor"}}];
// = doc.swatches.getSelected();
var pageNumber = 1;
var count = 0;
var spots = [];
if (selectedSwatches.length > 0) {
for (var i = 0; i < selectedSwatches.length; i++) {
var swatch = selectedSwatches[i]
var color = swatch.color;
// Spot
if (color.typename == "SpotColor") {
count++;
spots.push(color.spot.name);
color = color.spot.color;
if (count % 10 == 0)
pageNumber++;
}
}
alert(spots.toString());
} else {
alert("No Swatches Selected.");
}
}
<button onclick="main()">Main</>

How can get only the last element from an array javascript

I'm trying to get the only last visited page by the user, it should update on every page. I tried to save the URL in session cookie from there I'm retrieving the last visited page.
This is my code:
function getSecondCookie(cSname) {
var name = cSname + "=";
var ca = document.cookie.split(';');
for ( var i = 0; i < ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name) == 0)
return c.substring(name.length, c.length);
}
return "";
}
function checkHistory(targetId) {
var history = getSecondCookie("history");
var htmlContent = '';
if (history != "") {
var insert = true;
var sp = history.toString().split(",");
for ( var i = sp.length - 1; i >= 0; i--) {
htmlContent += '<a class="previous_url" href="'
+ sp[i]
+ '">'
+ sp[i].substring(sp[i].lastIndexOf('/') + 1) + '</a><br>';
if (sp[i] == document.URL) {
insert = false;
}
document.getElementById(targetId).innerHTML = htmlContent;
console.log(sp[i]);
}
if (insert) {
sp.push(document.URL);
}
setSecondCookie("history", sp.toString(), 30);
} else {
var stack = new Array();
stack.push(document.URL);
setSecondCookie("history", stack.toString(), 30);
}
}
This is working fine how it has to.
At the moment it is showing like this:
https://www.example.com,https://www.example.com/about.html
and so on.
But I want here show only last element from an array. How can I do this?

let lastItem = array[array.length-1];

You can also do:
const last = array.slice(-1)[0]

Stop iterating and return true when a match is found between two arrays

I have two datasets, one in indexedDB and one in PouchDB (yes I know PouchDB is an implementation of indexedDB).
The one in indexedDB is a list of rooms, stored in indexedDB via a previous page, and displayed on the current page.
The one in PouchDB is the log of room usage recorded by a room auditor. I want to iterate through the first list, and check if each item appears in the list of audited rooms. If it does appear, I want to set a flag to indicate that.
Here's my Javascript. (I have run this in a browser and it does return true at some point in the process, because the console log output shows that, but the flag doesn't get set against the list item.)
I am wondering if it continues to loop through the audit records and overwrites the "true" value?
this is the function that queries indexedDB and calls the function that queries PouchDB:
function getRoomsInRoute() {
var routeNumber = $.jStorage.get('currentRoute', '');
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;
openRequest = window.indexedDB.open("rooms", 1);
openRequest.onupgradeneeded = function() {
var db = openRequest.result;
var itemStore = db.createObjectStore("rooms", {keyPath: "room_id"});
var index = itemStore.createIndex("rooms", ["route_number"]);
};
openRequest.onerror = function(event) {
console.error(event);
};
openRequest.onsuccess = function (event) {
var db = openRequest.result;
db.onerror = function(event) {
// Generic error handler for all errors targeted at this database's requests
console.error(event.target);
console.log("Database error: " + event.target.error.name || event.target.error || event.target.errorCode);
};
var transaction = db.transaction(['rooms'], "readwrite");
var itemStore = transaction.objectStore("rooms");
var index = itemStore.index("rooms", ["route_number"]);
console.log('DB opened');
var intRouteNumber = parseInt(routeNumber);
//var range = IDBKeyRange.only(intRouteNumber);
itemStore.openCursor().onsuccess = function(event) {
var cursor = event.target.result;
if(cursor) {
var audited;
if(cursor.value.route_number == routeNumber) {
if (checkIfAudited(cursor.value.room_seq)) {
var audited = ' <span class="checked"><i class="fa fa-check"></i></span>';
} else {
var audited = "";
}
$('#mylist').append("<li id="+ cursor.value.room_id +" rel="+ cursor.value.room_seq +"> " + '<small>'+ cursor.value.room_seq + '. </small>' + cursor.value.room_name + ''+audited+'</li> ');
}
cursor.continue();
} else {
console.log('Entries all displayed.');
if(!($.jStorage.get('reverseroute', ''))) {
reverseroute = 'asc';
} else {
reverseroute = $.jStorage.get('reverseroute', '');
}
appendHref(reverseroute);
}
};
// Close the db when the transaction is done
transaction.oncomplete = function() {
db.close();
};
};
}
and this is the function that queries PouchDB to see if it has been audited:
function checkIfAudited(roomseq) {
var today = new Date();
if(is_BST(today) == true) {
var currentHour = today.getHours()+1;
} else {
var currentHour = today.getHours();
}
var currentDay = today.getDate();
var currentMonth = today.getMonth();
options = {},
that = this,
pdb = new PouchDB('pouchroomusage');
options.include_docs = true;
var pouchOpts = {
skipSetup: true
};
var opts = {live: true};
pdb.allDocs(options, function (error, response) {
response.rows.some(function(row){
var auditTime = new Date(row.doc.timestamp);
var auditHour = auditTime.getUTCHours();
var auditDay = auditTime.getDate();
var auditMonth = auditTime.getMonth();
if(row.doc.sequence == roomseq && currentHour == auditHour && currentDay == auditDay && currentMonth == auditMonth) {
var isAudited = true;
console.log('RoomSeq: ' + roomseq + '; auditHour: ' + auditHour + '; currentHour: ' + currentHour + '; auditDay: ' + auditDay);
console.log('currentDay: ' + currentDay + '; auditMonth: ' + auditMonth + '; currentMonth: ' + currentMonth + '; isAudited: ' + isAudited);
} else {
var isAudited = false;
console.log('No matches');
}
return isAudited;
});
});
}
I have read a number of other questions and answers about comparing two arrays.
I don't know how to use a for loop with pdb.allDocs though :(
Here is the output from console.log:
49 No matches
RoomSeq: 1; auditHour: 14; currentHour: 14; auditDay: 16
currentDay: 16; auditMonth: 0; currentMonth: 0; isAudited: true
2300 No matches
So how do I get the second function to stop and return true when it hits a matching record in PouchDB?

First, I wouldn't get too fancy with exploiting the short-circuiting behavior of Array.prototype.some. Use the native functionality available to you. indexedDB provides a built in way to stop advancing a cursor, or load only a limited number of objects from a store.
Second, you probably want to avoid loading all objects from a store when you are only interested a in a few of those objects. Use a cursor to walk the store. Since you appear to want to stop iterating when meeting some condition, simply do not call cursor.continue at that point.
Third, is that even if decide to load all objects from the store first, it would be far better to use a for loop than exploit some. By exploit I mean use the function in a way other than it was intended. I bet that if you revert to using a for loop with a break statement, the code will be clearer and therefore it will be simpler to understand why the loop does not break when you expect it to do so.
Fourth, is that I would take the time to append results of an indexedDB query to an intermediate data structure, like an array, rather than immediately interacting with the DOM. It will separate things more, and you will find the code simpler to debug.
Fifth is that you should be very careful when mixing async calls together with indexedDB. indexedDB is known to have problems when you interleave calls to other promises.

It seems to me that the pouchdb method alldocs is asynchronous.
But you test audition in a synchronous way. Therefore whatever the pdb.alldocs callback function returns will be returned after the checkIfAudited is already returned. Therefore checkIfAudited always returns undefined.
In my opinion, you should create the pouchdb instance only once in temStore.openCursor().onsuccess. Then you need to properly return audit state in checkIfAudited function.
For example, you could do something like the following:
itemStore.openCursor().onsuccess = function(event) {
var cursor = event.target.result;
if (cursor) {
if (cursor.value.route_number == routeNumber) {
var audited;
options = {},
pdb = new PouchDB('pouchroomusage');
options.include_docs = true;
pdb.allDocs(options, function (error, allDocsResponse) {
if (checkIfAudited(allDocsResponse, cursor.value.room_seq)) audited = ' <span class="checked"><i class="fa fa-check"></i></span>'
else audited = "";
$('#mylist').append("<li id="+ cursor.value.room_id +" rel="+ cursor.value.room_seq +"> " + '<small>'+ cursor.value.room_seq + '. </small>' + cursor.value.room_name + ''+audited+'</li> ');
});
};
cursor.continue();
} else {
console.log('Entries all displayed.');
if(!($.jStorage.get('reverseroute', ''))) reverseroute = 'asc'
else reverseroute = $.jStorage.get('reverseroute', '');
appendHref(reverseroute);
};
};
And for checkIfAudited:
function checkIfAudited(allDocs, roomseq) {
var today = new Date();
if(is_BST(today) == true) {
var currentHour = today.getHours()+1;
} else {
var currentHour = today.getHours();
}
var currentDay = today.getDate();
var currentMonth = today.getMonth();
for (i=0; i<allDocs.rows.length; i++) {
var row = allDocs.rows[i];
var auditTime = new Date(row.doc.timestamp);
var auditHour = auditTime.getUTCHours();
var auditDay = auditTime.getDate();
var auditMonth = auditTime.getMonth();
if(row.doc.sequence == roomseq && currentHour == auditHour && currentDay == auditDay && currentMonth == auditMonth) {
console.log('RoomSeq: ' + roomseq + '; auditHour: ' + auditHour + '; currentHour: ' + currentHour + '; auditDay: ' + auditDay);
console.log('currentDay: ' + currentDay + '; auditMonth: ' + auditMonth + '; currentMonth: ' + currentMonth + '; isAudited: ' + isAudited);
return true; ///// <---- return that it is audited
} else {
console.log('No matches');
};
});
return false ///// <---- return false if no iteration has matched
}

This is what I ended up with after much tweaking.
Now it adds <span class="checked"><i class="fa fa-check"></i></span> more than once per <li> but at least it adds to every <li>.
So I did a little hack to the CSS to only display one span.checked:
.checked {
color: #fff;
background-color: #006338;
border-radius: 50%;
padding: 2px 3px;
}
/* only display the first instance of checked */
li > span.checked ~ .checked {
display: none;
}
(I also found and fixed another error in my script, where I wasn't setting route_number or room_id.)
function getRoomsInRoute() {
var routeNumber = $.jStorage.get('currentRoute', '');
var indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB || window.shimIndexedDB;
openRequest = window.indexedDB.open("rooms", 1);
openRequest.onupgradeneeded = function() {
var db = openRequest.result;
var itemStore = db.createObjectStore("rooms", {keyPath: "room_id"});
var index = itemStore.createIndex("rooms", ["route_number"]);
};
openRequest.onerror = function(event) {
console.error(event);
};
openRequest.onsuccess = function (event) {
var db = openRequest.result;
db.onerror = function(event) {
// Generic error handler for all errors targeted at this database's requests
console.error(event.target);
console.log("Database error: " + event.target.error.name || event.target.error || event.target.errorCode);

}
cursor.continue();

}

ReferenceError: "PropertiesService" is not defined

From the following question, I try to use part of the following code in an Adwords script
function runMe() {
var startTime= (new Date()).getTime();
//do some work here
var scriptProperties = PropertiesService.getScriptProperties();
var startRow= scriptProperties.getProperty('start_row');
for(var ii = startRow; ii <= size; ii++) {
var currTime = (new Date()).getTime();
if(currTime - startTime >= MAX_RUNNING_TIME) {
scriptProperties.setProperty("start_row", ii);
ScriptApp.newTrigger("runMe")
.timeBased()
.at(new Date(currTime+REASONABLE_TIME_TO_WAIT))
.create();
break;
} else {
doSomeWork();
}
}
//do some more work here
}
but I got ReferenceError: "PropertiesService" is not defined. (line 170) from google-apps-script. How could I fix that issue? Can you tell me if it works for you in Adwords?
UPDATED
Here is the function I build in considering the previous function :
function adjustCPCmax() {

var minCPC = 0.50;
var accountIterator = MccApp.accounts().get();
var mccAccount = AdWordsApp.currentAccount();
while(accountIterator.hasNext()) {
var account = accountIterator.next();

MccApp.select(account)
var campaignIterator = AdWordsApp.campaigns().get();
while (campaignIterator.hasNext()) {
var campaign = campaignIterator.next();
try {
var maxCPC = getMaxCPC(account, campaign)
}
catch(e) {

}
var REASONABLE_TIME_TO_WAIT = 4*6000;
var MAX_RUNNING_TIME = 1*6000;
try {
var scriptProperties = PropertiesService.getScriptProperties();
}
catch(e){
Logger.log(e)

break;
}
}
}
}
}
}
MccApp.select(mccAccount);
}
From that function, what could I do to fix that problem? It is bizarre because I could find documentation on the subject.

You are using AdWords Script which is different from Google Apps Script even though they share many APIs. Google Apps Script has access to Properties Service, AdWords Script does not. Evidence: the AdWords Script reference (screenshot) does not include Properties Service among Script Services.
You are using script properties to store one number, the current row number. An alternative is to store it in a spreadsheet, since AdWords Script has access to Spreadsheet service. So, at the beginning of the script you would have
var ss = SpreadsheetApp.openByUrl('...'); // url of some spreadsheet
var sheet = ss.getSheets()[0]; // first sheet in it
var cell = sheet.getRange("A1"); // storing the number in A1 cell
and then within the body of the script, replace
var startRow = scriptProperties.getProperty('start_row');
by
var startRow = cell.getValue() || 1; // 1 by default
and also replace
scriptProperties.setProperty("start_row", ii);
by
cell.setValue(ii);
This should do it.

Javascript error after upgrade to Drupal 7

I posted a similar question at the Drupal Forum, but I haven't had much luck.
I'm upgrading a site from D6 to D7. So far it's gone well, but I'm getting a Javascript error that I just can't pin down a solution for.
This is a cut down version of the whole script:
(function($) {
function sign(secret, message) {
var messageBytes = str2binb(message);
var secretBytes = str2binb(secret);
if (secretBytes.length > 16) {
secretBytes = core_sha256(secretBytes, secret.length * chrsz);
}
var ipad = Array(16), opad = Array(16);
for (var i = 0; i < 16; i++) {
ipad[i] = secretBytes[i] ^ 0x36363636;
opad[i] = secretBytes[i] ^ 0x5C5C5C5C;
}
var imsg = ipad.concat(messageBytes);
var ihash = core_sha256(imsg, 512 + message.length * chrsz);
var omsg = opad.concat(ihash);
var ohash = core_sha256(omsg, 512 + 256);
var b64hash = binb2b64(ohash);
var urlhash = encodeURIComponent(b64hash);
return urlhash;
}
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
Date.prototype.toISODate =
new Function("with (this)\nreturn " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
function getNowTimeStamp() {
var time = new Date();
var gmtTime = new Date(time.getTime() + (time.getTimezoneOffset() * 60000));
return gmtTime.toISODate() ;
}
}(jQuery));
The part that keeps throwing an error I'm seeing in Firebug is at:
Date.prototype.toISODate =
new Function("with (this)\n return " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
Firebug keeps stopping at "addZero is not defined". JS has never been my strong point, and I know some changes have been made in D7. I've already wrapped the entire script in "(function($) { }(jQuery));", but I must be missing something else. The same script works perfectly on the D6 site.
Here is the "fixed" version of the whole code with #Pointy suggestion added. All I left out is the part of the script for making the hash that goes to Amazon, and some of my declared variables.

Here's a better version of your code:
Date.prototype.toISODate = function() {
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
var d = this;
return d.getFullYear() + '-' +
addZero(d.getMonth() + 1) + '-' +
addZero(d.getDate()) + 'T' +
addZero(d.getHours()) + ':' +
addZero(d.getMinutes()) + ':' +
addZero(d.getSeconds()) + '.000Z';
};
That moves "addDate" inside the extension function, and it avoids the horrid with statement.
