How can I dynamically index through datalayer tags in GTM?

I'm using the DuracellTomi datalayer plugin to push cart data from woocommerce to a GTM model to handle some tracking.
The DuracellTomi plugin pushes content to the transactionProducts[] array in the following format:
transactionProducts: Array[1]
0 : Object
category:""
currency:"USD"
id:8
name:"Test"
price:100
quantity:"1"
sku:8
I'd like to loop through this array and unstack it into three separate arrays, pricelist, skulist, and quantitylist. Currently I anticipate doing so as some variation on
//Get Product Information
if(stack = {{transactionProducts}}){
for(i = 0; i < stack.length; i++) {
if(stack.i.sku){
skulisttemp.i = stack.i.sku;
}
if(stack.i.price){
pricelisttemp.i = stack.i.price;
}
if(stack.i.sku){
quantitylisttemp.i = stack.i.quantity;
}
}
{{skulist}} = skulisttemp;
{{pricelist}} = pricelisttemp;
{{quantitylist}} = quantitylisttemp;
}
Obviously this is not going to work because of how the tag referencing is set up, but I'm wondering if anyone has dealt with this and knows what the best way to index through these arrays might be. (For those who don't know, the square bracket array call doesn't work with GTM variables and instead the . format is used instead.)

You would need to create 3 variable type custom javascript function that picks your required value from dataLayer and returns it in an array.
Something like
function(){
var products = {{transactionProducts}};
var skuArray = [];
for(i = 0; i < products.length; i++) {
if(products[i].sku){
skuArray.push(products[i].sku)
}
}
return skuArray
}
hope this helped you :)

How to get the 'Value' using 'Key' from json in Javascript/Jquery

I have the following Json string. I want to get the 'Value' using 'Key', something like
giving 'BtchGotAdjust' returns 'Batch Got Adjusted';
var jsonstring=
[{"Key":"BtchGotAdjust","Value":"Batch Got Adjusted"},{"Key":"UnitToUnit","Value":"Unit To Unit"},]

Wow... Looks kind of tough! Seems like you need to manipulate it a bit. Instead of functions, we can create a new object this way:
var jsonstring =
[{"Key":"BtchGotAdjust","Value":"Batch Got Adjusted"},{"Key":"UnitToUnit","Value":"Unit To Unit"},];
var finalJSON = {};
for (var i in jsonstring)
finalJSON[jsonstring[i]["Key"]] = jsonstring[i]["Value"];
You can use it using:
finalJSON["BtchGotAdjust"]; // Batch Got Adjusted

As you have an array in your variable, you have to loop over the array and compare against the Key-Property of each element, something along the lines of this:
for (var i = 0; i < jsonstring.length; i++) {
if (jsonstring[i].Key === 'BtchGotAdjust') {
console.log(jsonstring[i].Value);
}
}
By the way, I think your variable name jsonstring is a little misleading. It does not contain a string. It contains an array. Still, the above code should give you a hint in the right direction.

Personally I would create a map from the array and then it acts like a dictionary giving you instantaneous access. You also only have to iterate through the array once to get all the data you need:
var objectArray = [{"Key":"BtchGotAdjust","Value":"Batch Got Adjusted"},{"Key":"UnitToUnit","Value":"Unit To Unit"}]
var map = {}
for (var i=0; i < objectArray.length; i++){
map[objectArray[i].Key] = objectArray[i]
}
console.log(map);
alert(map["BtchGotAdjust"].Value)
alert(map["UnitToUnit"].Value)

accessing nested properties based on structure

Could anyone please give me an alternate syntax to the following
var id = '-JLxSeCPUCVN13FxifTY';
var ResultsContainer = results[id];
var i=0;
for(var k in ResultsContainer)
{
var TheArrayOfObjectsThatIneed = ResultsContainer[Object.keys(ResultsContainer)[i]];
console.log(TheArrayOfObjectsThatIneed);
//loop the TheArrayOfObjectsThatIneed do the processing
i++;
}
as you see in the image i have an array within an object within an object and i have no idea what the property names are but the structure is always the same {results:{id:{idthatidontknow:[{}]}}} and all i need is to access the arrays
the above code is working nicely but i am new to javescript and i was wondering if there is a nicer syntax and if i am doing it the right way

Perhaps something like this?
var id = '-JLxSeCPUCVN13FxifTY';
var ResultsContainer = results[id];
for(var k in ResultsContainer) {
if (ResultsContainer.hasOwnProperty(k)) {
var TheArrayOfObjectsThatIneed = ResultsContainer[k];
console.log(TheArrayOfObjectsThatIneed);
//loop the TheArrayOfObjectsThatIneed do the processing
}
}

Javascript regular expressions for Query Builder

This may have been asked in the past but I couldnt find a suitable answer. What I am looking for is a method to extract parameters from an sql query such as below. The queries will always be an EXEC statement followed by the query name, and possible parameters.
Here is an example of what I may recieve
EXEC [dbo].[myProcedure] #Param1
This could also be as follows
EXEC [dbo].[myProcedure] #Param1, #Param2, #Param3
Those are the only types of queries that the input will take. As for why I am doing this, well thats another question all together, and I am pretty set on going down this route.
What I am looking for is to be able to take the above strings and produce an array of values such as
['#Param1','#Param2','#Param3',....]
I originally tried to just parese using a simple while statement but I seem to have huge issues there.
I hope this question makes sense,
Cheers,
Nico
[Edit]
Sorted this by using the following statement
function eParams(e) {
var i = e.indexOf('#');
if (i <= 0)
return;
e = e.substring(i);
var p = e.split(',');
var eList = [];
var s = '';
for (var i = 0, j = p.length - 1; i <= j; i++) {
var sP = p[i].trim();
if (sP.indexOf('#') < 0)
continue;
eList.push(sP);
}
}

var str = 'EXEC [dbo].[myProcedure] #Param1, #Param2, #Param3';
(str).match(/(#[^\s,]+)/g);
will return an array.

var s = "EXEC [dbo].[myProcedure] #Param1, #Param2, #Param3";
var i = s.indexOf('#');
var a = s.substr(i).split(/\s*,\s*/);
(error checking omitted)

Accessing and updating an object variable,or associative array

This is my script, which I manged to put together using code on this link :
Setting up a variable length two-dimensional array
stringWithSeper = "Panther^Pink,Green,Yellow|Dog^Hot,Top";
var blocks = stringWithSeper.split("|");
for (var i = 0; i < blocks.length; i++) {
temp = blocks[i].split("^");
result[temp[0]] = temp[1].split(",");
}
I'm confused. What's the structure of "result" ? Is it
result = {"Panther":{"Pink","Green","Yellow"}, "Dog":{"Hot","Top"}}
If not, what is it? I've been breaking my head over this for the past 3 days.

Here is your answer: alert(JSON.stringify(result))
Result: {"Panther":["Pink","Green","Yellow"],"Dog":["Hot","Top"]}
