I have a hta file which connects to a database via ADO and then prints to a table. However my code triggers a syntax error at the getstring line and a object does support property or method 'write' error at the document.write section of the code for the table. I am struggling to figure out how to use this getstring method as from my understanding it should be the most efficient way to print out the table.

I'm trying to create a trigger button that, when pressed, will display a value from an excel cell in alert box or on the page.
below is all I could get, but it doesn't display anything on the page.
update: I managed to do this using ActiveX, but I don't want to use this library for some reasons. Do you have any idea how I could do it?
update code:
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.15.6/xlsx.full.min.js"></script>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>Excel to HTML</title>
</head>
<body>
<p>Press to show</p>
<input type="button" onclick="ReadData(4, 2) ; msgprint()" value="Show" />
<div id="div1">
<script>
function ReadData(cell, row) {
var excel = new ActiveXObject("Excel.Application");
var excel_file = excel.Workbooks.Open("mypah/myworkbook.xlsx");
var excel_sheet = excel.Worksheets("Sheet1");
var data = excel_sheet.Cells(cell, row).Value;
document.getElementById("div1").innerText = data;
}
</script>
</div>
<script>
function msgprint() {
alert(document.getElementById("div1").innerText);
}
</script>
</body>

I'm working in VSCODE. I have an html page and I want to include an external javascript file in it.
this is the html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Javascript Exercise</title>
<link rel="stylesheet" href="./assets/css/styles.css">
</head>
<body onload="addTable()">
<div class="title">Reports</div>
<!-- singolo run test -->
<div class="block">
<h1> Ultimo test eseguito </h1>
<div id="myDynamicTableTitles" class="table"></div>
<div id="myDynamicTable" class="table"></div>
</div>
<!-- JAVASCRIPT -->
<script src="./index.js"></script>
</body>
</html>
I know for sure that the js I wrote works, because if I put the js directly inside the <script></script> the page works.
Any idea on why, if I put it into an external file, it doesn't load? I'm also sure that the path "./index.js" it's correct.
I've noticed that if I click directly on the file html it works (like from the computer explorer). But if I load the project trough VSCode, it doesn't.
when I execute npm start it compile and gives me an http://localhost:xxxx
To make an example...
Maybe the script have an error?
function addTable(table) {
//Maybe you miss something? Here's an example
// get the reference for the body
var body = document.getElementsByTagName("body")[0];
// creates a <table> element and a <tbody> element
var tbl = document.createElement("table");
var tblBody = document.createElement("tbody");
// creating all cells
for (var i = 0; i < 2; i++) {
// creates a table row
var row = document.createElement("tr");
for (var j = 0; j < 2; j++) {
// Create a <td> element and a text node, make the text
// node the contents of the <td>, and put the <td> at
// the end of the table row
var cell = document.createElement("td");
var cellText = document.createTextNode("cell in row "+i+", column "+j);
cell.appendChild(cellText);
row.appendChild(cell);
}
// add the row to the end of the table body
tblBody.appendChild(row);
}
// put the <tbody> in the <table>
tbl.appendChild(tblBody);
// appends <table> into <body>
body.appendChild(tbl);
// sets the border attribute of tbl to 2;
tbl.setAttribute("border", "2");
}

It sounds like you are using the Live HTML Previewer extension which says:
Note: Javascript is not supported in preview
Use a browser to test your browser-dependant JS.

expected output : رقم البطاقة
actual output : رÙ٠اÙبطاÙØ©
try adding the codepage option to help parse foreign languages such as
XLSX.read(data, {type: ..., codepage: 28596});
where 28596 is for ISO 8859-6 Arabic.
Try going through https://github.com/sheetjs/js-codepage to find the codepage ID depending on the language you're parsing.
I am new to JavaScript and I am trying to do something very simple. I wan to appear array[1] text in firstDiv's innerHTML when I click button.
I have followed all instructions but still it's not working.

<body>
<button id="stylesChanger">Change the text !</button>
<div id="firstDiv">This sis some text</div>
<script type="text/javascript">
var myArray=new Array[];
myArray[0]="pizza";
myArray[1]="chocolate";
document.getElementById("stylesChanger").onclick=function(){
document.getElementById("firstDiv").innerHTML=myArray[1];
}
</script
</body>
</html>
change your var myArray=new Array[]; to var myArray=[];
Then it will work
var myArray=[];
myArray[0]="pizza";
myArray[1]="chocolate";
document.getElementById("stylesChanger").onclick=function(){
document.getElementById("firstDiv").innerHTML=myArray[1];
}
<button id="stylesChanger">Change the text !</button>
<div id="firstDiv">This sis some text</div>
This code will make sure you get the first element of myArray on button click. And sets the div text as myArray first element.
Working Sample: JSFIDDLE
var myArray = new Array();
myArray[0] = 'pizza';
myArray[1] = 'chocolate';
var btn = document.getElementById('stylesChanger');
btn.addEventListener('click', getArrayFirstElement, false);
function getArrayFirstElement(){
document.getElementById("firstDiv").innerHTML = myArray[0];
}
I have a javascript file which contains some data array and a function. I am using this function to display a table on the html page when it loads and on the click of a button. The error I am getting is:

My javascript function file is called table.js and contains:
var ORDER = {

};
function Order(ref, grower, item) {
this.order_reference = ("o" + ref);
this.grower_reference = grower;
this.item_ordered = item;
}
var order1 = new Order(1, "grower2", "item");
ORDER.orders.push(order1);
function addTable(orders) {
var table = document.createElement("TABLE");
table.setAttribute("id", "myTable");
document.body.appendChild(table);
for (var i = 0; i < orders.length; i++) {
var order = orders[i];
var row = document.createElement("TR");
var refCell = document.createElement("TD");
var growerCell = document.createElement("TD");
var itemCell = document.createElement("TD");
row.appendChild(refCell);
row.appendChild(growerCell);
row.appendChild(itemCell);
var ref = document.createTextNode(order.order_reference);
var grower = document.createTextNode(order.grower_reference);
var item = document.createTextNode(order.item_ordered);
refCell.appendChild(ref);
growerCell.appendChild(grower);
itemCell.appendChild(item);
table.appendChild(row);
document.body.appendChild(document.createElement('hr'));
}
}
window.addEventListener('load', function() {
addTable(ORDER.orders)
});
Where do I need to define addTable? How should I do this?
Also, the error with the GET. This is the line where I include the script. How can I stop this error occurring?
Thank you for the suggestions. They helped me to look at the correct piece of code to find the error so I have no fixed it.
It was an error with my folders and the path I was specifying. I originally had my .js file in my 'views' folder and was using ../views/table.js. This threw the not defined error so I created a new folder called 'js' and copied the file into here and specified it using /js/table.js and now it works.
From what I understand ../ looked in the parent directory of the folder I was in, whereas I needed to be 2 folders up, so starting with just a slash started the search from the root directory, found a folder called js and then found the addTable function as expected.
