I neet to read excel file that contains Arabic characters but that characters appear not correctly

<script>
$('#input-excel').change(function(e){
var reader = new FileReader();
reader.readAsArrayBuffer(e.target.files[0]);
var fu1 = document.getElementById("input-excel");
var name = fu1.value;
name = name.split("\\").pop();
reader.onload = function(e) {
var data = new Uint8Array(reader.result);
var wb = XLSX.read(data,{type:'array',charset:'utf-8'});
var htmlstr = XLSX.write(wb,{charset:'utf-8',type:'binary',bookType:'html',cellDates:true, cellStyles:true});
alert(htmlstr);
$('#wrapper')[0].innerHTML += htmlstr;
var rows = document.getElementsByTagName("table")[0].rows;
alert(document.getElementsByTagName('head')[0].innerHTML);
}
});
</script>
</body>
</html>
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'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>
</html>
Ok, so all I want to do is : whenever I write something in the Input and press the Button, a new HTML page gets created. But I also want to set the page's name and location. Tried searching it, couldn't find any results...

var bookId;
bookCreateButton.addEventListener('click', createBook);
function generateRandomNumber() {
var randomNumber = Math.floor(1000000000 + Math.random() * 900000000);
var rn = randomNumber.toString();
return rn;
}
function createBook() {
bookName = bookNameInput.value;
bookId = generateRandomNumber();
fbn = bookName + '_' + bookId
var bookLi = document.createElement("li");
bookLi.classList.add("book-li")
var bookLiA = document.createElement("a");
bookLiA.innerText = bookName;
bookLiA.href = fbn + ".html";
document.getElementById("books-list").appendChild(bookLi);
bookLi.appendChild(bookLiA);
bookNameInput.value = "";
}
Tried using :
const newDoc = document.implementation.createHTMLDocument(title)
But doesn't creates any page...
I already answered your question in comments, so I'm writing this down as a answer so it might be helpful for others too.
So as i was saying it is totally possible to save the file directly from the client side without any need of server or special file system permission on client side -
In Short You can do something like this, Follow this step-by-step -
Get the value of the text input using input.value
Create a Blob out of It
Create a DOM element of anchor element with download attribute
Convert the Blob to an URL Using URL.createObjectURL and Chane the href of previously created anchor element to the returning url
Click on the anchor element without appending it to the DOM
Here is the Code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

padding: 0;
box-sizing: border-box;
margin: 0;
}
</style>
</head>
<body style="padding: 20px">
<textarea
placeholder="Enter Your Content Here"
style="width: 100%; height: 500px; font-size: 18px; padding: 18px"
></textarea>
<br /><br />
<button>Download Text as HTML page</button>
<script>
let btn = document.querySelector("button");
let text = document.querySelector("textarea");
btn.addEventListener("click", () => {
if (!/^\s*$/.test(text.value)) {
let a = document.createElement("a");
a.setAttribute("download", "download.html");
let blob = new Blob(text.value.split(""));
let url = URL.createObjectURL(blob);
a.href = url;
a.click();
text.value = "";
} else {
alert("Blank text");
text.value = "";
}
});
</script>

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 am trying to make a basic to do application.
Here is what I have done so far;
When the user clicks a button a prompt appears asking the user to enter a task.
The task will then be stored in an array
I have displayed the array in the console. However, I am having trouble displaying the array on the web page:
var toDoItems = [];
var parsed = "";
document.getElementById("addItem").onclick = function() {
var userInput = prompt("Enter your Todo: ")
toDoItems.push = userInput;
console.log(toDoItems);
}

The first thing is you need to use Array.push() and not Array.push = someVal. Then you can loop over to the values and create a list of elements in the HTML:
var toDoItems = [];
var parsed = "";
document.getElementById("addItem").onclick = function() {
var nHTML = '';
var userInput = prompt("Enter your Todo: ")
toDoItems.push(userInput);
toDoItems.forEach(function(item) {
nHTML += '<li>' + item + '</li>';
});
document.getElementById("item-list").innerHTML = '<ul>' + nHTML + '</ul>'
}

</head>
<body>
<h1>My Tasks</h1>
<button id="addItem">Add item</button>
<div id="item-list">
</div>
<script src="js/script.js"></script>
</body>
You can use map() to map over the toDoItems and convert each items to html code and then use join() to combine the array into one string of HTML code.
Like this:
const HTML = toDoItems.map( item => `<li>${item}</li> ` ).join('');
document.getElementById("item-list").innerHTML = '<ul>' + HTML + '</ul>'
Edit: Fixed typo (should be join, not joint)
Loop over toDoItems, create a <p> tag and append it to #item-list:
toDoItems.forEach((item) => {
let p = document.createElement('p');
p.innerText = item;
document.querySelector('#item-list').appendChild(p);
});
You can use innerHTML for this
document.getElementById("item-list").innerHTML += "<p>" +userInput+"</p>";

Check below I think this may help you
I removed style from your code for my convenience

<head>
<link href='https://fonts.googleapis.com/css?family=Lato:100,300,400,300italic' rel="stylesheet" type="text/css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<title>To Do List</title>
<script>
function myFunction(){
var toDoItems = [];
var parsed ="";
var userInput = prompt("Enter your Todo: ")
toDoItems.push = userInput;
document.getElementById("item-list").innerHTML=userInput;
console.log(toDoItems);
}
</script>
</head>
<body>
<h1>My Tasks</h1>
<button id="addItem" onclick="myFunction()">Add item</button>
<div id="item-list">
</div>
</body>
</html>
The Code above has an drawback: It erases the old value of userInput when you enter a new value in prompt().
I propose:
document.getElementById("item-list").innerHTML +=userInput+"";

I follow Javascript - How to extract filename from a file input control and I have few problems with getting file name from input/upload file. I use this code to get file name from input file
var fileInput = document.getElementById('upload_file').files[0].name;
But when I change with another file, I still get my old file name and I need to refresh my browser to get latest file name. How to fix something like this?
<html>
<head>
<meta charset="utf-8">
<script src="http://code.jquery.com/jquery-3.3.1.js"></script>
</head>
<body>
<input type="file" id="upload_file">
<br>
<h1 id="nama_file"></h1>
<script>
var fileInput = document.getElementById('upload_file').files[0].name;
//var filename = fileInput.files[0].name;
console.log(fileInput);
document.getElementById('nama_file').innerText = fileInput;
</script>
</body>
</html>
You need an event:
var filename = document.getElementById('filename');
document.getElementById('upload_file').addEventListener('change', function(e) {
filename.innerText = e.target.files[0].name;
});
<input type="file" id="upload_file">
<br>
<h1 id="filename"></h1>
You can add a event on every load and change the inner text of 'name_file' accordingly.
