How to force the download of a link with JavaScript?
To force the download of a link with JavaScript, we can create a hidden link and click it programmatically.
For instance, we write:
<button>
download
</button>
to add a button.
Then we write:
const download = document.querySelector("button");
download.onclick = () => {
const anchor = document.createElement("a");
anchor.href =
"https://file-examples-com.github.io/uploads/2018/04/file_example_AVI_480_750kB.avi";
anchor.target = "_blank";
anchor.download = "example.pdf";
anchor.click();
};
to select the button with document.querySelector.
Then we set its onclick property to a function that creates the link with document.createElement.
And we set the href to the file we want to download.
And we set the download property to the file name of the file.
Finally, we call click to click it to start the download.
