How to write to next column when running a loop?

I would like to extract all links from a folder in google drive and write two columns, one containing the link, and the next column containing the file name.
I'm new to google scripting and wrote this code:
function myFunction() {
var ss=SpreadsheetApp.getActiveSpreadsheet();
var s=ss.getActiveSheet();
var c=s.getActiveCell();
var fldr=DriveApp.getFolderById("0B37vVx5p-eGMTmJmTF9JOUwxZnc");
var files=fldr.getFiles();
var names=[],f,str;
while (files.hasNext()) {
f=files.next();
str='=hyperlink("' + f.getUrl() + '")';
names.push([str]);
}
s.getRange(c.getRow(),c.getColumn(),names.length).setFormulas(names);
}
function myFunction() {
var ss=SpreadsheetApp.getActiveSpreadsheet();
var s=ss.getActiveSheet();
var c=s.getActiveCell();
var fldr=DriveApp.getFolderById("0B37vVx5p-eGMTmJmTF9JOUwxZnc");
var files=fldr.getFiles();
var names=[],f,str;
while (files.hasNext()) {
f=files.next();
str='=" + f.getName() + "';
names.push([str]);
}
s.getRange(c.getRow(),c.getColumn(),names.length).setFormulas(names);
}
The problem is that after writing the links in the first column, it overwrites it with the names in the first column. How can I specify what column the second piece of code should be written to?

There's no real reason to grab these in separate functions, you could just push them both to the same array then insert into the sheet, the code below should do what you're expecting:
function getFolders() {
var ss=SpreadsheetApp.getActiveSpreadsheet();
var s=ss.getActiveSheet();
var c=s.getActiveCell();
var fldr=DriveApp.getFolderById("0B37vVx5p-eGMTmJmTF9JOUwxZnc");
var files=fldr.getFiles();
var names=[],f,url,name;
while (files.hasNext()) {
f=files.next();
url='=hyperlink("' + f.getUrl() + '")';
name='="' + f.getName() + '"';
names.push([url,name]);
}
s.getRange(c.getRow(),c.getColumn(),names.length, 2).setFormulas(names);
}
I had to tweak name='="' + f.getName() + '"'; because the quotes weren't quite in the right place, it was pushing that string itself to the array rather than the filename.
Pushing both of the values to the array like this means you don't need to offset the range because the array will span 2 columns when you use setValues(), hence why I had to add 2 for numColumns in the setValues() too.

On a Google Apps Script project each function should have unique names otherwise only the last function in the order that they are loaded at execution time will be executed. So, in first place, the hyperlink formulas aren't never written.
By the other hand, as was mentioned on a previous answer, there is no need to have separate functions to write on each column, one single function could fill both columns at the same time.
On this code line:
names.push([str]);
The argument por push is an array having a single value. Replace this argument by an array incluiding the values for both columns. To make the minimum changes to you first function, rename the str variable, add a second code line for the second column with a proper and unique variable name , i.e. (as was shown on the previous answer):
url='=hyperlink("' + f.getUrl() + '")';
name='=" + f.getName() + "';
names.push([url,name]);
And lastly, add the number of columns to the last statement
s.getRange(c.getRow(),c.getColumn(),names.length, 2).setFormulas(names);
Don't forget to delete the second function named myFunction

Use Range.offset:
Returns a new range that is offset from this range by the given number of rows and columns (which can be negative). The new range is the same size as the original range.

Javascript ID Extracted From String Not Working

Here's the situation:
function STP() { var LOC = window.location.href;
var CSV = LOC.substring(LOC.indexOf(',')+1);
var ARR = CSV.split(',');
var STR = ARR[ARR.length -1 ];
var POS = window.document.getElementById(STR).offsetTop;
alert( STR ); };
Explained:
When the page loads, the onload calls the script.
The script gets the location.href and Extracts the element ID by
creating an array and referencing the last one.
So far so good.
I then use that to reference an element ID to get its position.
But it doesn't work.
The STR alert indicates the proper value when it's placed above POS, not below. The script doesn't work at all below that point when the STR var reference is used.
However if I do a direct reference to the ID ('A01') no problem.
Why does one work and not the other when both values are identical? I've tried other ways like using a hash instead of a comma and can extract the value that with .location.hash, but it doesn't work either.

The problem is that when you do
LOC.substring(LOC.indexOf(',') + 1);
you're putting everything after the , into the CSV variable. But there is a space between the comma and the 'A01'. So, the interpreter reduces it to:
var POS = window.document.getElementById(' A01').offsetTop;
But your ID is 'A01', not ' A01', so the selector fails.
function STP() {
var LOC = 'file:///M:/Transfers/Main%20Desktop/Export/USI/2018/Catalog/CAT-Compilations-01a.htm?1525149288810, A01';
var CSV = LOC.substring(LOC.indexOf(',') + 1);
var ARR = CSV.split(',');
var STR = ARR[ARR.length - 1];
console.log(`'${STR}'`);
}
STP();
To solve this, you can increase the index by one:
LOC.substring(LOC.indexOf(',') + 2);
But it would probably be better not to put spaces in URLs when not necessary - if possible, send the user to 'file:///M:/Transfers/Main%20Desktop/Export/USI/2018/Catalog/CAT-Compilations-01a.htm?1525149288810,A01' instead.

Unable to Get Output From While Loop in Javascript

I'm working on my final project of the Winter 2017 quarter to demonstrate how to use Regular Expressions in both C# and JavaScript code behind pages. I've got the C# version of my demonstration program done, but the JavaScript version is making me pull what little hair I have left on my head out (no small achievement since I got a fresh buzz cut this morning!). The problem involves not getting any output after applying a Regular Expression in a While loop to get each instance of the expression and printing it out.
On my HTML page I have an input textarea, seven radio buttons, an output textarea, and two buttons underneath (one button is to move the output text to the input area to perform multiple iterations of applying expressions, and the other button to clear all textareas for starting from scratch). Each radio button links to a function that applies a regular expression to the text in the input area. Five of my seven functions work; the sixth is the one I can't figure out, and the seventh is essentially the same but with a slightly different RegEx pattern, so if I fix the sixth function, the seventh function will be a snap.
(I tried to insert/upload a JPG of the front end, but the photo upload doesn't seem to be working. Hopefully you get the drift of what I've set up.)
Here are my problem children from my JS code behind:
// RegEx_Demo_JS.js - code behind for RegEx_Demo_JS
var inputString; // Global variable for the input from the input text box.
var pattern; // Global variable for the regular expression.
var result; // Global variable for the result of applying the regular expression to the user input.
// Initializes a new instance of the StringBuilder class
// and appends the given value if supplied
function StringBuilder()
{
var strings = [];
this.append = function (string)
{
string = verify(string);
if (string.length > 0) strings[strings.length] = string;
}
this.appendLine = function (string)
{
string = verify(string);
if (this.isEmpty())
{
if (string.length > 0) strings[strings.length] = string;
else return;
}
else strings[strings.length] = string.length > 0 ? "\r\n" + string : "\r\n";
}
this.clear = function () { strings = []; };
this.isEmpty = function () { return strings.length == 0; };
this.toString = function () { return strings.join(""); };
var verify = function (string)
{
if (!defined(string)) return "";
if (getType(string) != getType(new String())) return String(string);
return string;
}
var defined = function (el)
{
// Changed per Ryan O'Hara's comment:
return el != null && typeof(el) != "undefined";
}
var getType = function (instance)
{
if (!defined(instance.constructor)) throw Error("Unexpected object type");
var type = String(instance.constructor).match(/function\s+(\w+)/);
return defined(type) ? type[1] : "undefined";
}
}
Within the code of the second radio button (which will be the seventh and last function to complete), I tested the ScriptBuilder with data in a local variable, and it ran successfully and produced output into the output textarea. But I get no output from this next function that invokes a While loop:
function RegEx_Match_TheOnly_AllInstances()
{
inputString = document.getElementById("txtUserInput").value;
pattern = /(\s+the\s+)/ig; // Using an Flag (/i) to select either lowercase or uppercase version. Finds first occurrence either as a standalone word or inside a word.
//result = pattern.exec(inputString); // Finds the first index location
var arrResult; // Array for the results of the search.
var sb = getStringBuilder(); // Variable to hold iterations of the result and the text
while ((arrResult = pattern.exec(inputString)) !==null)
{
sb.appendLine = "Match: " + arrResult[0] ;
}
document.getElementById("txtRegExOutput").value = sb.toString();
/* Original code from C# version:
// string pattern = #"\s+(?i)the\s+"; // Same as above, but using Option construct for case insensitive search.
string pattern = #"(^|\s+)(?i)the(\W|\s+)";
MatchCollection matches = Regex.Matches(userTextInput, pattern);
StringBuilder outputString = new StringBuilder();
foreach (Match match in matches)
{
string outputRegExs = "Match: " + "\"" + match.Value + "\"" + " at index [" + match.Index + ","
+ (match.Index + match.Length) + "]" + "\n";
outputString.Append(outputRegExs);
}
txtRegExOutput.Text = outputString.ToString();
*/
} // End RegEx_Match_The_AllInstances
I left the commented code in to show what I had used in the C# code behind version to illustrate what I'm trying to accomplish.
The test input/string I used for this function is:
Don’t go there. If you want to be the Man, you have to beat The Man.
That should return two hits. Ideally, I want it to show the word that it found and the index where it found the word, but at this point I'd be happy to just get some output showing every instance it found, and then build on that with the index and possibly the lastIndex.
So, is my problem in my While loop, the way I'm applying the StringBuilder, or a combination of the two? I know the StringBuilder code works, at least when not being used in a loop and using some test data from the site I found that code. And the code for simply finding the first instance of "the" as a standalone or inside another word does work and returns output, but that doesn't use a loop.
I've looked through Stack Overflow and several other JavaScript websites for inspiration, but nothing I've tried so far has worked. I appreciate any help anyone can provide! (If you need me to post any other code, please advise and I'll be happy to oblige.)

how to add numbers with an infinite number of digits using column addition?

I am trying to develop the addition program using column addition in javascript, For e.g: 53,22 , we add numbers from the right 3+2 and 5+2 finally results in 75, the main problem is with large numbers i am trying to develop a program which can implement addition of large numbers.so that i don't get gibberish like 1.26E+9, when adding large numbers. i tried doing it by defining the code like below
function add(a,b)
{
return (Number(a) + Number(b)).toString();
}
console.log(add('58685486858601586', '8695758685'));
i am trying to get the added number without getting the gibberish like 5.8685496e+16

You can add them digit by digit.
function sumStrings(a, b) { // sum for any length
function carry(value, index) { // cash & carry
if (!value) { // no value no fun
return; // leave shop
}
this[index] = (this[index] || 0) + value; // add value
if (this[index] > 9) { // carry necessary?
carry.bind(this)(this[index] / 10 | 0, index + 1); // better know this & go on
this[index] %= 10; // remind me later
}
}
var array1 = a.split('').map(Number).reverse(), // split stuff and reverse
array2 = b.split('').map(Number).reverse(); // here as well
array1.forEach(carry, array2); // loop baby, shop every item
return array2.reverse().join(''); // return right ordered sum
}
document.write(sumStrings('58685486858601586', '8695758685') + '<br>');
document.write(sumStrings('999', '9') + '<br>');
document.write(sumStrings('9', '999') + '<br>');
document.write(sumStrings('1', '9999999999999999999999999999999999999999999999999999') + '<br>');

I would keep all values as numbers until done with all the calculations. When ready to display just format the numbers in any way you want. For example you could use toLocaleString.

There are several libraries for that
A good rule of thumb is to make sure you do research for libraries before you actually go ahead and create you're own proprietary implementation of it. Found three different libraries that all solve your issue
bignumber.js
decimal.js
big.js
Example
This is how to use all three of the libraries, BigNumber coming from the bignumber.js library, Decimal from decimal.js and Big from big.js
var bn1 = new BigNumber('58685486858601586');
var bn2 = new BigNumber('8695758685');
console.log(bn1.plus(bn2).toString());
bn1 = new Decimal('58685486858601586');
bn2 = new Decimal('8695758685');
console.log(bn1.plus(bn2).toString());
bn1 = new Big('58685486858601586');
bn2 = new Big('8695758685');
console.log(bn1.plus(bn2).toString());
The console's output is :
58685495554360271
58685495554360271
58685495554360271

In Qualtrics surveys, how can you use JavaScript to dynamically set the range of a slider?

I was making a survey in Qualtrics, and needed to have my items show different values of the slider depending on a variable, in my case, the value from a loop and merge. That didn't seem like a thing that you could do with piped text, so I had to figure out how to do it in Javascript.
I'm just posting this as an opportunity to provide the answer I found on my own. As usual with Qualtrics, your mileage may vary, and this may need to be modified for your specific situation. In particular, the question IDs and postTags change depending on whether it is in a loop/merge, and perhaps on other factors.

Put the following code into the javascript section of the question:
// Set the slider range
// First define the function to do it
setSliderRange = function (theQuestionInfo, maxValue) {
var postTag = theQuestionInfo.postTag
var QID=theQuestionInfo.QuestionID
// QID should be like "QID421"
// but postTag might be something like "5_QID421" sometimes
// or, it might not exist, so play around a bit.
var sliderName='CS_' + postTag
window[sliderName].maxValue=maxValue
// now do the ticks. first get the number of ticks by counting the table that contains them
var numTicks = document.getElementsByClassName('LabelDescriptionsContainer')[0].colSpan
// do the ticks one at a time
for (var i=1; i<=numTicks; i++) {
var tickHeader='header~' + QID + '~G' + i
// the first item of the table contains the minimum value, and also the first tick.
// so we do some tricks to separate them out in that case.
var tickSpanArray = $(tickHeader).down("span.TickContainer").children
var tickSpanArrayLength=tickSpanArray.length
var lastTickIndex=tickSpanArrayLength - 1
var currentTickValue = tickSpanArray[lastTickIndex].innerHTML
currentTickValue=currentTickValue.replace(/^\s+|\s+$/g,'')
console.log('Tick value ' + i + ' is ' + currentTickValue)
// now get the new value for the tick
console.log('maxValue: ' + maxValue + ' numTicks: ' + numTicks + ' i: ' + i)
var newTickValue = maxValue * i / numTicks //the total number of ticks
tickSpanArray[lastTickIndex].innerHTML=newTickValue.toString()
console.log('Changed tick value to ' + newTickValue)
}
}
var currentQuestionInfo = this.getQuestionInfo()
var currentQuestionID = currentQuestionInfo.QuestionID
// Now call the function
setSliderRange(currentQuestionInfo, theMaxValueYouWant)
