Checking if a cell is empty on google scripts

I'm trying to make a form in google sheets so that if on column E there's a name (or any non-null value), it checks that the rest of the fields have been filled on columns F, G, H, etc... for this I've made two arrays, one with the values of the column E and the other with the values on the row that is being checked. The problem I'm encountering is with the null condition in the second for iteration
var range = R13A.getRange("E7:E15");
var values = range.getValues();
var i = [];
for (var y = 0; y < values.length; y++)
{
if (values[y]!="" && values[y].toString().trim()!="") //here it checks if a name is there
{
i.push(y);
var valRow = Number(i)+Number(range.getRow());
var range1 = R13A.getRange("G"+valRow+":T"+valRow);
var values1 = range1.getValues();
for (var x=0;x<values1.length;x++)
{
SpreadsheetApp.getUi().alert(values1[x]); // this part is just to check what values there are on the cells, it always returns ",,,,,,,," which means the cells actually are empty
if (values1[x]=="") // And here it should check if on the same row there are any blank cells. **THIS IS THE CONDITION THAT ISN'T BEING MET, WHETHER THE CELL HAS SOMETHING WRITTEN ON IT OR NOT**
{
validator = validator+" "+R13A.getRange(String.fromCharCode(7+y)+5).getValue(); //this saves the field names that need to be filled
}
}
}
}
If I check for the values of the cells separately rather than in an array, it does work, which I guess means the problem I have is with my array of data.
Thanks in advance

I tried to check what is the value of values1[x] and upon testing, it seems it returns an array.
since getValues do return a 2D array, you need to access values1[x] as values1[0][x] instead since we are always sure that there is only a single row and traverse the columns.
Since your validator variable as of now doesn't work, I did simplify it with printing we have blank cells instead.
this is the code I tested.
for(var y = 0; y < values.length; y++){
if (values[y] && values[y].toString().trim()) {
i.push(y);
var valRow = Number(y) + Number(range.getRow()); // you used Number(i) here but it should be Number(y)
var range1 = R13A.getRange("G" + valRow + ":T" + valRow);
var values1 = range1.getValues();
for (var x = 0; x < values1[0].length; x++) { // changed values1 to values1[0] instead
if (!values1[0][x] && !values1[0][x].toString().trim()) { // changed values1 to values1[0] instead
Logger.log("we have blank cells");
}
}
}
}
As you can see, I simplified some checking on my part, feel free to use or modify it on yours.
Here is the sample sheet:
Where cells painted with red are blank (8 in total)
and here is the output of the code:
As we can see in the output, we were able to count them properly.
If you have any more questions, feel free to ask me.

Return an array of (edited) matched items of two other arrays and (unedited) non-matched items

My goal
I'm trying to link rows in two different sheets in the same spreadsheet according to a value in a cell. The basic idea is that if a value in column B in Sheet1 has a matched value in column B in Sheet2, an hyperlink should be added to the cell with the matched value in Sheet1 linking to the whole row of the matched value in the Sheet2.
What I did
As you can see from the code below, it looks for the matches, if it's found, it edits the matched values to add the hyperlinks. I don't only want to push the "linked" matched values into the new array, I also want the non-matched values without the link. The idea is that the link will be added if a match is found, otherwise the value will still be added, just without the link.
function linkToContacts(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var Sheet1 = ss.getSheetByName("Sheet1");
var Sheet2 = ss.getSheetByName("Sheet2");
var Sheet2ID = Sheet2.getSheetId();
var arrSheet1 = Sheet1.getRange(4,2,Sheet1.getLastRow()-3).getValues(); // -3 because I have 3 row as headers before the data, which start in row 4 col B
var arrSheet2 = Sheet2.getRange(4,2,Sheet2.getLastRow()-3).getValues(); // -3 because I have 3 row as headers before the data, which start in row 4 col B
var arrOutput = [];
for(var i = 0; i<arrSheet1.length;i++){
for(var j = 0; j<arrSheet2.length;j++) {
if(arrSheet1[i][0] === arrSheet2[j][0]){
arrOutput.push(['=HYPERLINK("#gid=' + Sheet2ID + '&range=' + Sheet2.getRange(j+4,2,1,Sheet2.getLastColumn()-1).getA1Notation() + '";"' + arrSheet1[i][0] + '")']);
} else {
arrOutput.push([arrSheet1[i][0]]);
}
}
}
Sheet1.getRange(4,2,Sheet1.getLastRow()).clearContent();
Sheet1.getRange(4,2,arrOutput.length).setValues(arrOutput);
}
The problem
The two arrays contain only unique values respectively. The problem is that, because of the double loop, each item is checked by the length of arrSheet2. So for instance let's imagine this scenario:
var arrSheet1 = [apple,avocado,banana];
var arrSheet2 = [apple,banana,mango,];
the arrOutput will result in:
arrOutput = [
apple(link),apple,apple,
avocado,avocado,avocado,
banana(link),banana,banana
];
In a quick, probably unelegant, way to solve the issue I've tried to delete the duplicates frm arrOutput but obviously the value with the link and the values without are different so the best it can get with this solution is this:
arrOutput = [
apple(link),apple,
avocado,
banana(link),banana
];
Question
Is there a smarter/more efficient way to get to
arrOutput = [apple(link),avocado,banana(link)];
or in case what I'm doing actually makes sense, what I should do to get to the result above?

You could use Array.prototype.filter to create a new array that contains only matching elements. If no elements are found this will return an empty array.
var arrSheet1 = ['apple','avocado','banana'];
var arrSheet2 = ['apple','banana','mango'];
var intersect = arrSheet1.filter(function (element) {
return arrSheet2.includes(element);
});
// ['apple','banana']
Or without an Array.prototype.includes polyfill:
var intersect = arrSheet1.filter(function (element) {
return arrSheet2.indexOf(element) !== -1);
})

Issue:
Double looping and pushing array elements multiple times
Solution:
Use break and conditional if statements to control logic
Flow:
If hyperlink is pushed, break the second sheet loop
Only push Sheet1 element if there's no hyperlinks in Sheet2(i.e., Wait till the last element of Sheet2 is iterated)
Snippet:
for(var i = 0; i<arrSheet1.length;i++){
for(var j = 0, k = arrSheet2.length-1; j<=k; j++) {// modified
if(arrSheet1[i][0] === arrSheet2[j][0]){
arrOutput.push(['=HYPERLINK("#gid=' + Sheet2ID + '&range=' + Sheet2.getRange(j+4,2,1,Sheet2.getLastColumn()-1).getA1Notation() + '";"' + arrSheet1[i][0] + '")']);
break; //break j loop to continue next i loop
} else if(j === k){//push sheet1 only on the last element
arrOutput.push([arrSheet1[i][0]]);
}
}
}
Note:
Use of objects {} might be better. Convert sheet2 array to object {val1:hash,val2:hash,...}. Then you can easily check if sheet1 elements are present in sheet2 using in

Looping through a Google App script and setting multiple nonconsecutive values

This was difficult to title without examples and context. Here goes...
I have a Google app script which searches through a column of student ids (column A on the compiledDATA sheet) and then sets a value (an award) in column B of the same row. This works fine for a single student id, but I need the script to loop and set the same award value for all of the students in the GroupAwardIDs range which is located on a separate sheet called Group Awards.
Here's a link to my sample spreadsheet.
The values to be set are nonconsecutive, and in actual use there may be over a thousand to be set at a time.
How can I achieve this in a quick and efficient way without running into quota issues?
Here's the script (please excuse all the comments - it helps me keep track):
function AwardGroup() {
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var StarLog = sheet.getSheetByName("compiledDATA");
var GroupAward = sheet.getRangeByName("GroupAward").getValue();
var GroupAwardIDs = sheet.getRangeByName("GroupAwardIDs").getValue(); // THESE ARE THE IDS OF STUDENTS WHO WILL RECEIVE THE AWARD. HOW DO SET VALUES FOR ALL AND ONLY THESE IDS?
var IDs = sheet.getRangeByName("StudentIDs").getValues(); // all of the student IDs
for (var i = 0; i < IDs.length; i++) {
if (IDs[i] == "123461") { // THIS WORKS IF HARDCODE A SINGLE ID
var rowNumber = i+3; // find row and add 3 to compensate for GroupAward range staring at row 3
var StarLogCurrent = StarLog.getRange("B"+rowNumber).getValue(); // locates students award log cell using A1 notation
var appendAward = GroupAward.concat(StarLogCurrent); // prepends new award to previous awards
StarLog.getRange("B"+rowNumber).setValue(appendAward); //write new star log
}
}
}

You want to put GroupAward ("'Group Awards'!B3") to the column "B" of "compiledDATA" with the same row, when StudentIDs ("compiledDATA!A3:A1000") and GroupAwardIDs ("'Group Awards'!B7:B1002") are the same. If my understanding is correct, how about this modification? I think that there are several solutions for your situation. So please think of this as one of them.
Modification points :
Retrieve all GroupAwardIDs.
Remove empty elements in GroupAwardIDs.
Search IDs using GroupAwardIDs and put GroupAward when the IDs is the same with GroupAwardIDs.
Put the values with GroupAward.
Modified script :
Please modify as follows.
From :
var GroupAwardIDs = sheet.getRangeByName("GroupAwardIDs").getValue(); // THESE ARE THE IDS OF STUDENTS WHO WILL RECEIVE THE AWARD. HOW DO SET VALUES FOR ALL AND ONLY THESE IDS?
var IDs = sheet.getRangeByName("StudentIDs").getValues(); // all of the student IDs
for (var i = 0; i < IDs.length; i++) {
if (IDs[i] == "123461") { // THIS WORKS IF HARDCODE A SINGLE ID
var rowNumber = i+3; // find row and add 3 to compensate for GroupAward range staring at row 3
var StarLogCurrent = StarLog.getRange("B"+rowNumber).getValue(); // locates students award log cell using A1 notation
var appendAward = GroupAward.concat(StarLogCurrent); // prepends new award to previous awards
StarLog.getRange("B"+rowNumber).setValue(appendAward); //write new star log
}
}
To :
var GroupAwardIDs = sheet.getRangeByName("GroupAwardIDs").getValues(); // Modified
var IDs = sheet.getRangeByName("StudentIDs").getValues();
// I modified below script.
GroupAwardIDs = GroupAwardIDs.filter(String);
var res = IDs.map(function(e){
return GroupAwardIDs.filter(function(f){
return f[0] == e[0]
}).length > 0 ? [GroupAward] : [""];
});
sheet.getRange("compiledDATA!B3:B1000").setValues(res);
If I misunderstand your question, please tell me. I would like to modify it.
Edit :
You want to add GroupAward to the original values at column B. I understood what you want to do like this. If my understanding is correct, please modify to as follows. In this sample, I used ", " as the delimiter.
var GroupAwardIDs = sheet.getRangeByName("GroupAwardIDs").getValues(); // Modified
var IDs = sheet.getRangeByName("StudentIDs").getValues();
// I modified below script.
var columnB = sheet.getRange("compiledDATA!B3:B1000");
var valColB = columnB.getValues();
GroupAwardIDs = GroupAwardIDs.filter(String);
var res = IDs.map(function(e, i){
return GroupAwardIDs.filter(function(f){
return f[0] == e[0]
}).length > 0 ? [valColB[i][0] ? GroupAward + ", " + valColB[i][0] : GroupAward] : [valColB[i][0]]; // Modified
});
columnB.setValues(res);

qualtrics javascript: autopopulate matrix table using previous answers

I ask the same matrix table (multiple answer) question twice in my Qualtrics survey. When I display the question to the user the second time, I want the answers to be auto populated from the first time the user answered the question. I've looked at the code snippets in the documentation, so I know how to select the checkboxes in the current question, e.g.
for (var i = 1; i <= rows; i++) {
for (var j = 1; j <= cols; j++) {
this.setChoiceValue(i, j, true);
}
}
My issue is that I can't figure out how to get the selected answers from the previous question. I have tried something like this but it doesn't work (cannot read property 'attr' of null):
var isChecked = $("#QR~QID2~" + i + "~" + j").attr('checked');
This page from the documentation suggests using piped text, something along the lines of:
var selectedChoice = "${q://QID2/ChoiceGroup/SelectedChoices}";
This seems to give me the unique statements in the rows of the survey that have been selected, but I need to get the selected answer (col) for each statement (row) in the question. I'm not sure how to formulate the correct piped text.
Any advice would be much appreciated! Thanks.
Edit 1: Here is the code I ended up using.
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place Your Javascript Below This Line*/
var numChecks = $(this.getQuestionContainer()).select('input[type="checkbox"]');
var numCols = 4;
var numRows = numChecks.length / numCols;
var map = {};
//I won't have more than 20 rows in the matrix
map[1] = "${q://QID53/SelectedAnswerRecode/1}";
map[2] = "${q://QID53/SelectedAnswerRecode/2}";
map[3] = "${q://QID53/SelectedAnswerRecode/3}";
map[4] = "${q://QID53/SelectedAnswerRecode/4}";
map[5] = "${q://QID53/SelectedAnswerRecode/5}";
map[6] = "${q://QID53/SelectedAnswerRecode/6}";
map[7] = "${q://QID53/SelectedAnswerRecode/7}";
map[8] = "${q://QID53/SelectedAnswerRecode/8}";
map[9] = "${q://QID53/SelectedAnswerRecode/9}";
map[10] = "${q://QID53/SelectedAnswerRecode/10}";
map[11] = "${q://QID53/SelectedAnswerRecode/11}";
map[12] = "${q://QID53/SelectedAnswerRecode/12}";
map[13] = "${q://QID53/SelectedAnswerRecode/13}";
map[14] = "${q://QID53/SelectedAnswerRecode/14}";
map[15] = "${q://QID53/SelectedAnswerRecode/15}";
map[16] = "${q://QID53/SelectedAnswerRecode/16}";
map[17] = "${q://QID53/SelectedAnswerRecode/17}";
map[18] = "${q://QID53/SelectedAnswerRecode/18}";
map[19] = "${q://QID53/SelectedAnswerRecode/19}";
map[20] = "${q://QID53/SelectedAnswerRecode/20}";
for (var i = 1; i <= numRows; i++) {
//Get the recode values for row i
var rowValues = map[i].split(",");
//Loop through all the recode values for the current row
for (var c = 0 ; c < rowValues.length; c++) {
var val = parseInt(rowValues[c].trim());
//Select the current question's checkboxes corresponding to the recode values
this.setChoiceValue(i, val, true);
}
}
});
Edit 2:
I'm getting some strange behavior now. I'm trying to populate a table with only 3 rows, so I would think that
"${q://QID53/SelectedAnswerRecode/1}";
"${q://QID53/SelectedAnswerRecode/2}";
"${q://QID53/SelectedAnswerRecode/3}";
would give me the values for the first three rows from the previous table for question "QID53" . But actually those return empty strings, and it's not until calling
"${q://QID53/SelectedAnswerRecode/5}";
"${q://QID53/SelectedAnswerRecode/6}";
"${q://QID53/SelectedAnswerRecode/7}";
that I get the first three values.
For a table of 14 rows, nothing returns until calling
"${q://QID53/SelectedAnswerRecode/4}";
and it leaves the last 3 rows in the table empty.
Am I wrong in assuming that the number after "SelectedAnswerRecode" is the row number? Is there something about an offset that I'm missing?

I think you'll want to pipe in the recode values. Something like:
var r1ar = parseInt("${q://QID2/SelectedAnswerRecode/1}");
var r2ar = parseInt("${q://QID2/SelectedAnswerRecode/2}");
Then set the values:
this.setChoiceValue(1, r1ar, true);
this.setChoiceValue(2, r2ar, true);
Make sure your recode values match the column ids.
Edits/additions based on comments below:
Piped values in the javascript get resolved server side before the page is sent to the browser, so they are fixed values. There is no way to make them dynamic in javascript. If your question has a variable number of rows due to display logic or carryover, you'll have to include all the possible piped values in the javascript, then check them to see which ones are valid.
For a multiple answer matrix, you can convert the comma separated list into an array using str.split(',') then loop through the array. Qualtrics includes spaces after the commas in comma separated lists, so you'll have to trim() the strings in the array.

JavaScript: If statement not working inside Loop

I'm writing the following code (a test as of now) using Google Scripts to pass data from one spreadsheet to another. The passing of the code is working just fine, however my second For loop – which I intend to use to detect duplicate values and avoid passing those rows over – is not working.
Checking the logs I see that even though the "i" and "j" values are correctly being passed inside the If block, the "if(sheetsIDHome[i] == sheetsIDTarget[j])" statement is never triggering, even when I confirm that both values are the same.
Any help would be greatly appreciated, thank you in advance!
function move(){
var homeBook = SpreadsheetApp.getActiveSpreadsheet();
var sheet = homeBook.getSheets()[0];//Sheet where my Home data is stored
var limit = sheet.getLastRow(); //number of rows with content in them
var evento = sheet.getRange(2, 1, limit-1).getValues(); //Even titles array
var descript = sheet.getRange(2,2,limit-1).getValues(); //Event Descriptions array
var tags = sheet.getRange(2,3,limit-1).getValues(); //Tags array
var sheetsIDHome = sheet.getRange(2,4,limit-1).getValues(); //ID's array
var targetBook = SpreadsheetApp.openById("1t3qMTu2opYffLmFfTuIbV6BrwsDe9iLHZJ_ZT89kHr8"); // Traget Workbook
var target = targetBook.getSheets()[0]; //Sheet1, this is my Target sheet
if (target.getLastRow() > 1){
var sheetsIDTarget = target.getRange(2, 4,target.getLastRow()-1).getValues();}
else{
var sheetsIDTarget = target.getRange(2, 4, 1).getValues();}
var targetRow = target.getLastRow()+1; //Target row to start pasting content
for (var i = 0; i < evento.length; i++) { //Loops throught every value from my Home sheet in order to pass it to my Target Sheet
var isKlar = 1; //This works as a switch, data passing will not activate if isKlar set to 0
Logger.log("Switch is: "+isKlar);
for(var j = 0; j < sheetsIDTarget.length; j++){ //While having a certain "i" value in place, will loop though all my values in my target array using the counter "j"
if(sheetsIDHome[i] == sheetsIDTarget[j]){ //If the ID of my curent row from Home matches any of the values in my target sheet, my "isKlar" switch should turn off and the break loop will be exited.
Logger.log("If Activated");
isKlar = 0;
break;}
else{Logger.log("ID's: "+sheetsIDHome[i] + " vs " + sheetsIDTarget[j]);}
}
if(isKlar === 1){ //data passing will not activate if isKlar set to 0
//pass data to the Target sheet
target.getRange(targetRow,1).setValue(evento[i]);
target.getRange(targetRow,2).setValue(descript[i]);
target.getRange(targetRow,3).setValue(tags[i]);
target.getRange(targetRow,4).setValue(sheetsIDHome[i]);
targetRow++; //select the next available row in ny Target sheet
}
}
}
Edit. - Right now I'm testing both ID arrays with the same numbers (e.g. 1, 2, 3, 4). The log inside my else statement does show the correct values being read for both arrays... I thought it was a scope issue, but now I'm not sure where the problem is.

the issue is a sheet range.getValues() returns an array of arrays, not an array of values.
values[0] is the first row, and values[0][0] is the first value in that first row. rework your code knowing this.
