I'm trying to clone a div in pure Javascript, however, cloneNode leads to duplicate ids (div_0). I would like to increment the id as div_1, div_2... and do the same to somevar = {'elem', 'div_1'}... Thanks

<html>
<head></head>
<body>
<div id="mydiv">
    <div id="div_0">
        <script type="text/javascript">
            <!--
            somevar = {'elem', 'div_0'};
            //-->
        </script>
        <p>HELLO</p>
    </div>
</div>

<a href="#" onclick="cloning()">CLONE</a>

<script type="text/javascript">
    function cloning() {
        var container = document.getElementById('mydiv');
        var clone = document.getElementById('div_0').cloneNode(true);
        container.appendChild (clone);
    }
</script>
</body>
</html>

Try this..

`

function cloning() {
    var container = document.getElementById('mydiv');
    var clone = document.getElementById('div_0').cloneNode(true);
    clone.setAttribute('id','div_'+document.getElementById('mydiv').getElementsByTagName('div').length);
    container.appendChild (clone);
}

`
