Certain number question being missed in regex

I have the following if statement that removes the first instances of a number followed by the period. However, I am noticing it is missing to catch some of them (ex. "16.", "23.", "24.", etc.) and not sure why.
Here is the function:
function quesCleanUp(ques){
//Checks the first instance of "." and removes it and the number
if(ques.match(/[0-9]\./g)?.length > 1){//(ques.match(/./g)?.length > 1){
var quesClean = ques.replace(/^[^\.]*\./, '').trim();
} else{
var quesClean = ques.trim();
}
return quesClean;
}
The following for loop extracts the question from the google form:
for (var i = 0; i < items.length; i++) {
var item = items[i];
switch(item.getType()) {
case FormApp.ItemType.MULTIPLE_CHOICE:
var question = item.asMultipleChoiceItem();
var ques = quesCleanUp(question.getTitle().trim());//replace(/\s/g, "");
var question_type = "Multiple Choice";
var optns = [];
var answr;
var answers = question.getChoices();
answer_val = false;
for (var j = 0; j < answers.length; j++) {
var clean = answers[j].getValue().trim();
optns.push(clean);
if(answers[j].isCorrectAnswer()){
answr = answers[j].getValue().trim();
for(var x = 0; x < optns.length; x++){
if(answr == optns[x]){
answer_val = true;
break;
}
}
}
}
var multiJSON = makeJSON(ques, question_type, optns, answr);
console.log("JSON1: " + JSON.stringify(multiJSON));
constructedJSON[i+1] = multiJSON;
break;
case FormApp.ItemType.CHECKBOX:
var question = item.asCheckboxItem();
//var ques = question.getTitle().trim();//.replace(/\s/g, "");
var ques = quesCleanUp(question.getTitle().trim());//replace(/\s/g, "");
var question_type = "CheckBox";
var optns = [];
var answr = [];
var answers = question.getChoices();
for (var j = 0; j < answers.length; j++) {
var clean = answers[j].getValue().trim();//replace(/\s/g, "");
optns.push(clean);
if(answers[j].isCorrectAnswer()){
answr.push(answers[j].getValue().trim());
}
}
var checkJSON = makeJSON(ques, question_type, optns, answr);
console.log("JSON2: " + JSON.stringify(checkJSON));
constructedJSON[i+1] = checkJSON;
break;
case FormApp.ItemType.PARAGRAPH_TEXT:
var question = item.asParagraphTextItem();
//var ques = question.getTitle().trim();//.replace(/\s/g, "");
var ques = quesCleanUp(question.getTitle().trim());//replace(/\s/g, "");
var question_type = "free response";
var optns = [];
var answr;
var paraJSON = makeJSON(ques, question_type, optns, answr);
console.log("JSON3: " + JSON.stringify(paraJSON));
constructedJSON[i+1] = paraJSON;
break;
case FormApp.ItemType.TEXT:
var question = item.asTextItem();
//var ques = question.getTitle().trim();
var question_type = "free response";
var ques = quesCleanUp(question.getTitle().trim());//replace(/\s/g, "");
var optns = "";
var answr = "";
var textJSON = makeJSON(ques, question_type, optns, answr);
console.log("JSON4: " + JSON.stringify(textJSON));
constructedJSON[i+1] = textJSON;
break;
}
The following example is the type of question 16. What is the meaning of life?
And the expected output: What is the meaning of life?

Try using /[0-9]+./g to catch more than one digit

As a quick fix, in the function quesCleanUp() try to change the line:
if(ques.match(/[0-9]\./g)?.length > 1){//(ques.match(/./g)?.length > 1){
With:
if (ques.match(/^[0-9]+\./g).length > 0) {
I suspect you got the downvotes because you posted the code with glared typos. It looks like you didn't even try to debug it first. And as the icing on the cake you accepted a wrong answer.
And probably the function can be boiled down to just one line:
const quesCleanUp = q => q.replace(/^\d+\./,'').trim();
Here is how it works:
var questions = ['1. aaa', '16. What', '23. That', 'No nums'];
const quesCleanUp = q => q.replace(/^\d+\./,'').trim();
questions.forEach(q => console.log(quesCleanUp(q)));
Expected output:
aaa
What
That
No nums

appendchild is not working

I am working on nested array. When i am trying to insert data to a div by using appendChild It is throwing an error saying Cannot read property 'appendChild' of null
My Code goes hear
<script>
var emp1 = [];
emp1["Emsno"] = 10001;
emp1["name"] = "jack";
emp1 ["sall"] = 5000;
var emp2 = [];
emp2["Emsno"] = 10002;
emp2["name"] = "Reck";
emp2 ["sall"] = 5500;
var emp3 = [];
emp3["Emsno"] = 10003;
emp3["name"] = "lama";
emp3 ["sall"] = 5300;
var emp4 = [];
emp4["Emsno"] = 10004;
emp4["name"] = "sam";
emp4 ["sall"] = 6000;
var emps = [emp1, emp2, emp3, emp4];
var Employedisplay = document.getElementById("Employedisplay");
function showEmployes(){
var n = emps.length;
for (i = 0; i < n ; i++){
var emp = emps[i];
for(var key in emp){
var NewDiv = document.createElement("div");
NewDiv.innerHTML = key + ": " + emp[key];
Employedisplay.appendChild(NewDiv);
}
var NewBrk = document.createElement("br")
Employedisplay.appendChild(NewBrk);
}
}
</script>
</head>
<body>
<input type = "button" id = "MyArray" value ="Show Emps" onclick="showEmployes()"/>
<hr>
<div id="Employedisplay"></div>
</body>
and it is working in this way
function showEmployes(){
var n = emps.length;
for (i = 0; i < n ; i++){
var emp = emps[i];
for(var key in emp){
var NewDiv = document.createElement("div");
NewDiv.innerHTML = key + ": " + emp[key];
document.getElementById("Employedisplay").appendChild(NewDiv);
}
var NewBrk = document.createElement("br")
Employedisplay.appendChild(NewBrk);
}
}
I am not understanding where i am going wrong in my first approach?

The below line of code is executed even before the browser add the #Employedisplay element in DOM.
var Employedisplay = document.getElementById("Employedisplay");
So when you click the button, Employedisplay variable is null
It's better to bootstrap your code on page load, or you can get the #Employedisplay element at the start of showEmployee method.

Javascript add row to HTML table with text and onClick

i am adding a new table row in javascript:
var i=1;
function addRow(seq, nominalcode, description, quantity, unitprice) {
seq = seq || '';
nominalcode = nominalcode || '';
description = description || '';
quantity = quantity || '';
unitprice = unitprice || '';
var tbl = document.getElementById('table1');
var lastRow = tbl.rows.length - 4;
//var iteration = lastRow - 1;
var row = tbl.insertRow(lastRow);
row.id = 'item_row_' + i;
var Cell0 = row.insertCell(0);
var elItemSequence = document.createElement('input');
elItemSequence.type = 'hidden';
elItemSequence.name = 'item_sequence' + i;
elItemSequence.id = 'item_sequence' + i;
elItemSequence.value = seq;
Cell0.appendChild(elItemSequence);
var elNominalcode = document.createElement('input');
elNominalcode.type = 'textarea';
elNominalcode.className = 'form-control';
elNominalcode.name = 'nominal_code' + i;
elNominalcode.id = 'nominal_code' + i;
elNominalcode.placeholder = 'Nominal Code';
elNominalcode.value = nominalcode;
Cell0.appendChild(elNominalcode);
var Cell1 = row.insertCell(1);
var elDescription = document.createElement('textarea');
elDescription.type = 'textarea';
elDescription.className = 'form-control';
elDescription.name = 'description' + i;
elDescription.id = 'description' + i;
elDescription.placeholder = 'Description';
elDescription.value = description;
elDescription.cols = 40;
elDescription.rows = 2;
Cell1.appendChild(elDescription);
var Cell2 = row.insertCell(2);
var elQuantity = document.createElement('input');
elQuantity.type = 'text';
elQuantity.className = 'form-control';
elQuantity.name = 'quantity' + i;
elQuantity.id = 'quantity' + i;
elQuantity.placeholder = 'Quantity';
elQuantity.value = quantity;
elQuantity.value = quantity;
Cell2 .appendChild(elQuantity);
var Cell3 = row.insertCell(3);
var elUnitPrice = document.createElement('input');
elUnitPrice.type = 'text';
elUnitPrice.className = 'form-control';
elUnitPrice.name = 'unitprice' + i;
elUnitPrice.id = 'unitprice' + i;
elUnitPrice.placeholder = 'Price';
elUnitPrice.value = unitprice;
Cell3.appendChild(elUnitPrice);
var Cell4 = row.insertCell(4);
var elDelete = document.createElement('a');
elDelete.href = '#';
elDelete.onclick = function(){ DeleteInvoiceLine(seq, i) };
elDelete.text = 'Delete' + i;
Cell4.appendChild(elDelete);
i++;
document.getElementById('numrows').value = (i-1);
//alert(i);
}
in the above code there is an onClick action which calls a function
but everytime the row is added its running the function, how can i make it only call the function on click of the a anchor
my function is:
function DeleteInvoiceLine(seq, row_num) {
alert(seq + '/' + row_num);
}

You can try anonymous function
elDelete.onclick = function(){ DeleteInvoiceLine(seq) };

Try this:
...
elDelete.setAttribute("onclick", "DeleteInvoiceLine("+ seq +","+ i +")");
....

There are several issues in your code.
1. elDelete.onclick=... not onClick
2. As you note DeleteInvoiceLine(seq) run at the moment the element created.
This is because you assign result of the function, not function to onclick event.
3. (not asked yet) What is sec variable? I suspect something like for(var sec=0;sec<N;sec++) and your code is inside the loop. This will not work (see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Closures).
4. elDelete.onclick = function(){ DeleteInvoiceLine(seq) }; doesn't work because sec is out of scope at the moment of click.
Some fixes.
var i = 0;
//...
for(var sec=0;sec<N;sec++){
//your code
elDelete.onclick = DeleteInvoiceLine(seq, i);//I keep it with purpose
//your code
}
//...
i++;
//The key moment
function DeleteInvoiceLine(seq, row_num){
//sec comes here from the loop
return function(){//note (); (sec) would kill all construction
//and in this context would be **event {type:'click'}
$.ajax(
//your code which uses **sec** and/or **row_num**
//this time sec and row_num are available from parent scope
);//$.ajax
}//return function
}//function DeleteInvoiceLine

Try putting %20 in place of spaces. Text in the submitted URL has spaces "Activity Notes – Optimizing Your Online.........". I did not survey the entire URL, but be sure to encode wherever needed.

Javascript/DOM: On a dynamically created form text object, how do you reference the value via DOM?

I have an array that looks like this:
grades[0] = ["A", 4.0, 0, "a"];
grades[1] = ["A-", 3.67, 0, "a-minus"];
grades[2] = ["B+", 3.33, 0, "b-plus"];
grades[3] = ["B", 3.0, 0, "b"];
grades[4] = ["B-", 2.67, 0, "b-minus"];
grades[5] = ["C+", 2.33, 0, "c-plus"];
grades[6] = ["C", 2.0, 0, "c"];
grades[7] = ["C-", 1.67, 0, "c-minus"];
grades[8] = ["D+", 1.33, 0, "d-plus"];
grades[9] = ["D", 1.0, 0, "d"];
grades[10] = ["D-", 0.67, 0, "d-minus"];
grades[11] = ["F", 0.0, 0, "f"];
and a dynamic form that looks like this:

myTr.appendChild(myTd4);
myTbody.appendChild(myTr);
myTable.appendChild(myTbody);
myDiv.appendChild(myTable);
}
}
And I'm trying to update the value of the button in Td4 (the last button) using this:
function writeGrades() {
clearForm();
for (var x=0; x < grades.length; x++) {
if (grades[x][2] > 0) {
for (var i=1; i <= grades[x][2]; i++) {
sGradeLog += grades[x][0] + ",";
sGradeValLog += grades[x][1] + ",";
iCumTotal += grades[x][1];
iNumOfGrades += 1;
}
}
}
for (var x=0; x < grades.length; x++) { //**this loop is where I'm trying to make this happen**
var myVal = grades[x][3];
var myEl = getElementById(document.form.myVal.value);
document.form.myEl.value = grades[x][2];
}
iGPA = iCumTotal / iNumOfGrades;
document.form.GPA.value = iGPA.toFixed(3);
document.form.cumTotal.value = iCumTotal.toFixed(3);
document.form.numOfGrades.value = iNumOfGrades;
document.form.gradeLog.value = sGradeLog;
document.form.gradeValLog.value = sGradeValLog;
}
I have tried many different ways of access the document.form.grades[x][3].value DOM object but it doesn't like the array reference not being an object. My most recent attempt was adding the .id value to the button and then trying to use getElementById() but that didnt' work either.
I'm a novice at JS so please assist where you can. TIA!

Like this : document.form[grades[x][3]].value ?
