Global variable not updating as expected

I am building a small tool using Apps Script. I can't seem to get the global variable (URL) to update to include the docId.
What I expect
Run the App function, which first creates a Google Doc and sets the global variable for the documentId (docId). Second it calls myOnClickhandler, which should take the global url variable that includes the updated docId.
What is happening:
The variable 'url' in myClickHandler is not updated to the value of 'docId' set in the createProject function.
var docId = "";
var url = "https://docs.google.com/document/d/" + docId + "/";
function doGet() {
var output = HtmlService.createHtmlOutputFromFile('MyUI');
return output;
}
function createProject(test="test"){
const doc = DocumentApp.create(test);
docId = doc.getId();// <-- Update global docId variable. Doesn't seem to be working.
Logger.log("Doc ID is: " + docId);
}
function myOnClickHandler(){
const myList = ["Hello from the server", url]
Logger.log("URL is: " + url);
}
function app(){
createProject();
myOnClickHandler();
}
Probably a simple mistake on my part, but I am banging my head against the wall on this one. Screenshot attached.

In JavaScript, strings are immutable. Use an arrow function and a template literal instead of a static text string, like this:
let docId;
const getUrl_ = (docId) => `https://docs.google.com/document/d/${docId}/`;
function test() {
docId = 'testString';
const url = getUrl_(docId);
console.log(url);
}

addPreSearch filter not applying

I am trying to use the addPreSearch function to add a custom filter to a lookup field, but the function does not seem to execute fully before the results of the lookup are displayed. The code for this looks something like this:
function onFieldChange(executionContext) {
var formContext = executionContext.getFormContext();
formContext.getControl("test_code").removePreSearch(testFunctionFilter);
formContext.getControl("test_code").addPreSearch(testFunctionFilter);
}
function testFunctionFilter(executionContext) {
var formContext = executionContext.getFormContext();
var record1 = formContext.getAttribute("test_record1_link").getValue(); //get linked record
var record1FullId, record1Id, stringRecordId, idLength, record1Guid = "0";
if (record1 != null) {
record1Id = record1[0].id;
record1Id = record1FullId.slice(1, -1);
stringRecordId = record1FullId.toString();
idLength = stringRecordId.length;
//Guid when retrieved from tablet does not have parenthesis on each end
if (idLength == 36) {
record1Guid = record1FullId;
} else {
record1Guid = recordId;
}
}
var fieldValue;
Xrm.WebApi.retrieveRecord("test_record1", record1Guid, "?$select=test_field1")
.then(function(result1) {
fieldValue = result1.test_field;
var options = generateOptions(executionContext, fieldValue); //creates option string using retrieved fieldValue
Xrm.WebApi.retrieveMultipleRecords("test_record2", options)
.then(function(result) {
var codes = getCodes(result2, fieldValue);
filter = generateFilter(codes, record1Guid); //creates custom filter using provided parameters
console.log(filter); //displays filter correctly
formContext.getControl("test_codelookup").addCustomFilter(filter, "test_coderecord"); //not working?
});
});
}
The filter is generated correctly using the functions used above whose definitions aren't shown. That isn't the issue. I've tried creating a separate test function where I hard coded one of the filters that the function above generated, and the lookup displayed the correct results. The testFunctionFilter should run to completion before the results of the lookup are displayed, correct? Because the filter is logged to the console after the results of the lookup appear. Are the nested asynchronous Xrm.WebApi calls somehow causing the issue? I'm not quite sure what is wrong. Please advise.

You are right. Xrm.WebApi calls are always Asynchronous, which is unusable in this case of adding dynamic filter using addCustomFilter.
You have to use XMLHttpRequest and make that call as Synchronous by setting third parameter as false like below:
var req = new XMLHttpRequest();
req.open("GET", Xrm.Utility.getGlobalContext().getClientUrl() +
"/api/data/v9.0/test_record1?$select=test_field1", false);

In order to work around the async delay, I think you're going to have to reorganise your code:
Add a form OnLoad event and execute the query to retrieve test_field1 and cache the results in a parameter
In the OnChange event, remove the presearch filter, re-execute the query to retrieve test_field1 and update the same parameter (from onload)
In testFunctionFilter use the cached results rather than building the presearch filter from scratch

In Karate DSL, calling a javascript file returns java.lang.RuntimeException

I have a javascript file I want to call. contents are below. When I tried calling the file, I keep getting a "no variable found with name: response" even though there is clearly a variable defined. The file executes fine within command-line using node so the javascript function is valid. Any thoughts? I attached the error message in a screenshot.
Javascript content in snippet below.
Karate script:
Scenario: Call JavaScript:
* def sample = read('classpath:reusable/gen-data.js')
* print someValue
function createTestData(sampleJson, fieldsToChange, numRecords) {
var testData = [];
for (var i = 0; i < numRecords; i++) {
var copy = JSON.parse(JSON.stringify(sampleJson));
fieldsToChange.forEach(function(fieldToChange) {
copy[fieldToChange] = copy[fieldToChange] + i;
});
testData.push(copy);
}
return {content: testData};
}
var testData = {
"country": "US",
"taskStatusCode" : "Closed",
"facilityCode" : "US_203532",
};
function getTestData() {
String testData = JSON.stringify(createTestData(testData, ["taskStatusCode", "facilityCode"], 1), null, 1);
console.log("all done getTestData()");
console.log("test data: \n" + testData);
return testData;
};
console.log("calling getTestData()");
getTestData();

I think this error is thrown when the JavaScript is not correct. For example in my case this JS file:
/* Set the custom authentication header */
function fn() {
var authToken = karate.get('authToken');
var out = {};
out['Auth-Token'] = authToken
return out;
}
This file will produce the "no variable found with name: response".
The reason is because "the right-hand-side (or contents of the *.js file if applicable) should begin with the function keyword." according to the karate docs (link).
Now by moving the comment and making the function keyword the first bit of text it works as expected:
function fn() {
/* Set the custom authentication header */
var authToken = karate.get('authToken');
var out = {};
out['Auth-Token'] = authToken
return out;
}
In the OP, the function keyword is the first thing in the file, but there is javascript outside the original function -- which I don't think is legal for karate syntax. In other words, everything has to be in the outer function.

My workaround was to use java instead of JavaScript.

Getting array values from multidimensional array in JavaScript

I'm in need of some minor assistance. I'm having trouble getting an array (larray3) populated with two other array objects (larray1 and larray2) to pass both from data.js into the subsequent model.js and view.js. Data.js correctly builds the multidimensional array however when the results are received in model.js/view.js I only receive the results for larray1. Because only the first values come thru I cannot tell if both larray1 and larray2 are actually passing thru. Can someone please tell me how I should alter my syntax in either model.js or view.js to access both array values or what else I could change? Thank you in advance.
data.js.
function getCountries(done) {
var sqlite3 = require('sqlite3').verbose();
var file = 'db/locations.sqlite3';
var db = new sqlite3.Database(file);
var larray1 = [];
var larray2 = [];
var larray3 = [];
db.all('SELECT * FROM Country', function(err, rows) {
// This code only gets called when the database returns with a response.
rows.forEach(function(row) {
larray1.push(row.CountryName);
larray2.push(row.CountryCode);
})
larray3.push(larray1);
larray3.push(larray2);
return done(larray3[0], larray3[1]);
});
db.close();
}
model.js
function Countries(done) {
//Pull location values from data
return getCountries(done);
}
view.js
function viewCountries() {
var viewCou = Countries(function(results) {
// Code only gets triggered when Countries() calls return done(...);
var container = document.getElementById('country-select');
var fragment = document.createDocumentFragment();
results.forEach(function(loc, index) {
var opt = document.createElement('option');
opt.innerHTML = loc;
opt.value = loc;
fragment.appendChild(opt);
});
container.appendChild(fragment);
})
}

In data.js you send two arguments to the done callback:
return done(larray3[0], larray3[1]);
This done function is passed through in your model.js:
return getCountries(done);
And that done is passed in from view.js:
Countries(function(results) { // ...
So it is this anonymous function (function(results) {...}) that is called in data.js. But notice that this function only has one parameter, so you're doing nothing with the second argument that data.js sends. result gets the value of larray3[0], but larray3[1] is not captured anywhere.
You could solve this in different ways. Personally, I think the design with two arrays is wrong from the start. I would not separate data that belongs in pairs (name and code) into two different arrays.
Instead make an array of objects, and pass that single array around:
In data.js:
rows.forEach(function(row) {
larray1.push({
name: row.CountryName,
code: row.CountryCode
});
})
return done(larray1);
In view.js:
opt.textContent = loc.name;
opt.value = loc.code;
Side-note: .textContent is preferred over .innerHTML when assigning plain text.

Passing result from .getJSON() to another function results in undefined

Good day everyone,
I am pulling back some data from a database (via a PHP script) using jQuery's .getJSON() method. This is all well and good, the data comes back just fine and as expected. The problem occurs when I try to pass the data to a secondary function, no matter how I try to access the values of that data they come back as undefined. I have a feeling I am overlooking something very simple but after a lot of trial and error I come to SO asking for an extra set of eyes.
Here is a simple example of the JavaScript code.
function fnCheck_Vis(Row, sField, sMode)
{
sField = sField+"_vis";
sTest = Row.sField.val();
alert(sTest); // Comes back as undefined.
}
$(document).ready(function()
{
$("#btnSearch").click(function()
{
$("#divResults").empty();
var ssearch = $("#ssearch").val();
var i = 0;
$.getJSON("get_results.php?keywords=" + ssearch,
function(Data)
{
var iRec = 0;
$.each(Data, function(i, Row)
{
fnCheck_Vis(Row, "slinkpic1", "Int");
var content = Row.slast;
$("#divResults").append(content);
iRec++;
});
alert(iRec + " records retrieved using AJAX.");
});
});
});
The first piece of the fnCheck_Vis() function works fine and "_vis" is appended to the field name, this is proper behavior. No matter how I try to access that member in the dataset (Row) I can not get a value back.
I really appreciate any insight that can be given on this issue.
Thanks,
Nicholas

It looks like you want to access the property of Row whose name is stored in sField, not its actual sField property. Try:
function fnCheck_Vis(Row, sField, sMode)
{
sField = sField + "_vis";
var sTest = Row[sField];
alert(sTest);
}
