How to add a number from a local txt file into JS "let" keyword

Question

I am trying to place a number from a local TXT file in the "let count = 0" instruction, so "let count = number.txt"

That way the counter will read the number placed on the txt file and perform the addition/subtraction operation.

Thank you!

<!DOCTYPE html>
<html>
<body>

<h1 class="counter-wolf-numbers">(..)</h1>
<button class="counter-wolf-minus">-</button>
<button class="counter-wolf-plus">+</button>


<script>
let counterDisplayElem = document.querySelector('.counter-wolf-numbers');
let counterMinusElem = document.querySelector('.counter-wolf-minus');
let counterPlusElem = document.querySelector('.counter-wolf-plus');

let count = 0;

updateDisplay();

counterPlusElem.addEventListener("click",()=>{
    count++;
    updateDisplay();
}) ;

counterMinusElem.addEventListener("click",()=>{
    count--;
    updateDisplay();
});

function updateDisplay(){
    counterDisplayElem.innerHTML = count;
};
</script>



</body>
</html>

You could use a file input to select the file you want, then use FileReader to read the contents of the file.

Thank you, but it looks like this method can't load the file from a local path – Y M Oct 29 '20 at 00:20
Correct. You would have to select the file. If you need to access a file simply by file path, you'll need to use something like node's file system. https://nodejs.org/api/fs.html – Edward Ellsworth Oct 29 '20 at 00:29
