Sometimes, we want to get the filename from the JavaScript FileReader.
In this article, we’ll look at how to get the filename from the JavaScript FileReader.
How to get the filename from the JavaScript FileReader?
To get the filename from the JavaScript FileReader, we can use the fileName property of the selected file.
For instance, we write:
<input type='file'>
to add a file input.
Then we write:
const reader = new FileReader();
reader.onload = (readerEvt) => {
console.log(readerEvt.target);
};
const input = document.querySelector('input')
input.addEventListener('change', (e) => {
const [file] = e.target.files
console.log(file.name)
reader.readAsDataURL(file)
})
to create the FileReader instance.
We select the input with document.querySelector.
Then we add a change event handler to the input with addEventListener.
In the event handler, we get the selected file with e.target.files.
Then we get the name of the selected file with file.name.
Conclusion
To get the filename from the JavaScript FileReader, we can use the fileName property of the selected file.
