How to download a file in JavaScript or jQuery

Question

I have file object

var File = new File(["aa"], "dek_iv");

can I download this one using JavaScript or jQuery

Answer 1

Here is an Example how you can download your file Object.

But this will return nothing since the file size is too small for the system to read.

function downloadFile() {

 var file = new File(["aa"], "dek_iv.txt");
    var link = document.createElement("a");
    link.download =file.name;
    link.href = file;
    link.click();
}

<button onclick="downloadFile()">Download File</button>

Answer 2

function downloadFile() {

 var file = new File(["aa"], "dek_iv.txt");
    var link = document.createElement("a");
    link.download =file.name;
    link.href = file;
    link.click();
}

<button onclick="downloadFile()">Download File</button>
