Sometimes, we want to access local files with JavaScript.
In this article, we’ll look at how to access local files with JavaScript.
How to access local files with JavaScript?
To access local files with JavaScript, we can let users choose local files with a file input.
Then we can read the file when they choose one or more files.
For instance, we write
<input type="file" />
to add a file input.
Then we get the select files with
const inputElement = document.getElementById("input");
const handleFiles = (e) => {
const fileList = e.target.files;
};
inputElement.addEventListener("change", handleFiles, false);
We select the input with getElementById.
Then we define the handleFiles function to get the selected files from e.target.files.
Next, we call addEventListener with 'change' to listen for file selections and run handleFiles to get the files selected when selection changes.
