google spreadsheet script changes comma to full-stop upon reading from a cell?

So, I'm trying to read data from a cell in Google Spreadsheet's script and something's not right for me. I made a quick test function that takes the data from the cell, turns it to a string and returns the result, like so:
function TEST(str)
{
return str.toString();
}
Then I made two test cells:
A1 with "17"
A2 with "135,136"
A3 with "1,11,29,43,68,74,109,122"
Then I called my function and I'm baffled by results
TEST(A1) returns "17"
TEST(A2) returns "135.136"
TEST(A3) returns "1,11,29,43,68,74,109,122"
So it seems that if there is exactly one comma it gets cast to a full-stop instead but if there are multiple none of them get replaced. What is going on and how can I read data from a cell as a string with 100% certainty that it won't get changed in any way?

Issue:
Some locations use , as decimal separator. So, 135,136 is a valid number(=135.136). But, 1,11,29,43,68,74,109,122 is not. Valid numbers are by default aligned to the right of the cell(Clear cell formatting to witness).
Solution(s):
Set your locale properly, if you're going to use ,s as commas and not as decimal separators OR
Input numbers as text. Use ' before inputting data in each cell. '135,136 OR
Send inputs as Text. =TEST(TO_TEXT(A1)) OR
Use range#getDisplayValues() instead.

The A Column where this data is stored, it's format should be changed and that would solve the issue.
Select A Column --> Format --> Number -- Plain Text. Changing the format will serve the purpose.
Hope it could help!.

Best way to concatenate multiple strings?

I have a project, where user can put in drop-down values that can be selected. One can select multiple values at a time. So, we have to store the selection and get it on edit mode.
First thought
Let's store them as comma separated in DB.
f.e.
If suggestions are A , B , C and user selects A and B, I was going to store A,B in DB and while getting back the value split it with comma.
Problem arises when user has genuine "comma" in the field, for an instance first,option & second,option. At that time joining with comma won't work.
Second thought
I can think of another option to store it in a stringified array format and parse it while getting back.
For the above instance, it would store the data as ["first,option","second,option"]. It seems to be a good (and only) option for me.
Even though I have a bit of hesitation doing so (which lead me questioning here!) because my users can access the api/DB value directly and for them it doesn't look good.
So, Is there any other way to address this issue to benefit both parties, developers and users? Thanks in advance!!

I'd suggest using a standardized format such as JSON, XML etc.
Serialize and parse and with a widely used library so all escaping of reserved / special characters is done for you. Rolling your own here will cause you problems!
Better yet, use different fields for each suggestion, this is a better design in general. As long as the number of potential fields is finite this will work, e.g. 1-10 suggestions.
If you're going down the JSON route, we can do this in JavaScript like this:
let suggestions = ['Choice A, commas are not, a problem, though punctuation is.', 'Choice B', 'Choice C'];
let json = JSON.stringify(suggestions);
// Save to DB
saveToDB(json);
let jsonFromDB = loadFromDB();
let deserializedSuggestions = JSON.parse(jsonFromDB);
console.log(deserializedSuggestions);

we use semicolon (;) for this exact use case in our current project.
So, as per your question, they will be stored in the DB as option1;option2;option3
and when we get it back from the DB we can use the split() method on it to convert it into an array of substrings.
var str = "option1;option2;option3";
var res = str.split(";");
console.log(res);
which would result in (3) ["option1", "option2", "option3"] in the console.
hope this helps.

Javascript - Update to pipe delimiter with array that contains commas

I've been looking through stack overflow and the internet in general for hours with no solution in site yet...
I'll explain what I'm attempting to do - I'm building a list, then using php explode command by comma so I can loop through it, and insert each record into the database.
However, I'm building the array javascript, and the values I'm building the array off of, contain commas, separating first name and last name (Format Ex: Firstname, Lastname).
I'm a beginner and I'm still learning, so any help to point in the right direction would be greatly appreciated. I'm wondering if I need to do math to count the commas on the php side in order to separate based off the comma count, or if this is achievable in javascript using regex..
Everything I've been looking at seems like I may have to learn some regex to resolve this... Perhaps there's a built in jQuery command to change delimiter that I haven't been able to find?
var labels = $('.list-left ul li.active').map(function(){
return $(this).text().split(',').join('|');
}).get();

Maybe like this:
var test='test1,test2,test3,test4';
var test_new=test.replace(new RegExp(',','g'), '|');
console.log(test_new);

xPath in selenium with multiple premises in multiple node layers

I am having a little problem with xpath in seleniumdriver.
I would like an xpath locator to narrow down its selection via two variables using exact matching at different points of the node hiearchy. This part is done.
You may imagine my case as addressing a two dimensional array in the xml with xPath, with each dimension being given as the two variables I have in it(they are standard text searches via js variables, not xpath variables).
What I'm struggling with is the resulting construction does not tell the difference between the elements of the first dimension, so as long as the given variable value is one of the dimensions, it will address every element in the second dimension fine. I can not assume they are unique or they are in any order. I am using it for testing so this is not acceptable.
How can I form an expression that will not doesn't do the same mistake?
I have tried the 'and' expression but both selenium and xpath tools say the value is '1' for 'found' but it doesn't give me a node locator to work with.
Example, my structure looks similar, so addressing it properly by x1/y1 for example looks fine.
//x1//y1
//x1//y2
//x2//y3
//x2//y4
//x3//y5
//x3//y6
Should work, works ok.
//x1x//y1
//x1x//y2
//x2x//y3
//x2x//y4
//x3x//y5
//x3x//y6
(Giving nonexistent input as 1st dimension.) My input is not fault tolerant, I look for exact value so the tests fail here as they should.
//x2//y1
//x2//y2
//x3//y3
//x3//y4
//x1//y5
//x1//y6
DING, the locator finds y values here when it should not(the y vales are on different leaves of the node tree). I need help with this.
Here is the locator in question:
return element(by.xpath(".//div[#name='typeList']//div[.//text()='" + moduleName + "']//div[./text()='" + typeName + "']")).getText();
TypeList is the name of the owner element, it does not make any differnece if I remove it, but please keep it in mind when giving me examples.

In the end, it was indeed a syntactical problem, before the text keywords.
I was trying this
//div[./text()='Zero']//div[./text()='Number']
Instead, I needed something like this.
//div[.//text()='Zero']/div[.//text()='Number']
Apparently the first one does looks for 'Number' regardless the value of the first constraint as long as every is defined in my file(does not have to be in its upward xnode path.)
As a final note, I advise against using the chrome xpath helper as its behavior is near random, it gives different results after deleting and replacing the same expression. Ugh. The only other one for chrome is adware... I figured my result out by trial and error with the firefox xpath checker tool.
1, I ended up needing to additionally add an node upwards for the element for angular select ui tool(we use selectize.js, a searchable select box), else it was confused what to return, but this is unrelated to the original question as I tried that before with the original expression.
2, I also had to add a node between the first and second text search, else it would look for the second expression in the first one too, eg. looking for Number in Zero, and treat it like a valid value if found. The problem still occurs the other way around, this can be fixed too by applying additional type/name constraints in the first one(not in final example to save space).
So this is what I ended up with:
.//div[#name='typeList']//div/div[.//text()='Zero']/div/div/div[.//text()='Number']

jQuery tablesorter - sorting a column with mixed text and numbers

I have a table with a column of data that is mixed text and numbers. I'm sorting it using jQuery and the tablesorter plugin. The data that won't sort correctly is equipment tags, for example, "AHU-1", "AHU-2", "AHU-10". The problem is, given those example values, AHU-10 will be placed between AHU-1 and AHU-2. I've found forcing a 'digit' sort doesn't solve the problem.
Here's my question: 1) Does anyone know of an existing parser that I can use in this situation? If there isn't one then I'll need to write my own parser, in which case 2) How should I write the parser? Should I try and translate every letter to a number and do a numeric sort? That's my initial thought.
One more thing, I don't know for sure that a hyphen will be the delimiter. "AHU-1" could also be "AHU1", or "AHU 1", or "AHU:1", or something else.

You do need to write your own parser. What you are looking for is called "natural sort". There are plenty of javascript natural sort algorithms out there. I couldn't find one prewritten for the tablesorter plugin, but googling turns up quite a few.

Assuming all you need to do is sort any string of the pattern AAA-1 as AAA-01 you could do the following:
var myTextExtraction = function(node)
{
// extract data from markup and return it
return node.childNodes[0].childNodes[0].innerHTML
.replace(/([A-Z]{3}-)(\d)/,'$1-0$2');
}
$(document).ready(function()
{
$("#myTable").tableSorter( {textExtraction: myTextExtraction} );
}
);
