Download attribute on A tag not working in IE

Question

From the following code I'm creating a dynamic anchor tag which downloads a file. This code works well in Chrome but not in IE. How can I get this working

<div id="divContainer">
    <h3>Sample title</h3>
</div>
<button onclick="clicker()">Click me</button>

<script type="text/javascript">

    function clicker() {
        var anchorTag = document.createElement('a');
        anchorTag.href = "http://cdn1.dailymirror.lk/media/images/finance.jpg";
        anchorTag.download = "download";
        anchorTag.click();


        var element = document.getElementById('divContainer');
        element.appendChild(anchorTag);
    }

</script>

Answer 1

Internet Explorer does not presently support the Download attribute on A tags.

See http://caniuse.com/download and http://status.modern.ie/adownloadattribute; the latter indicates that the feature is "Under consideration" for IE12.
