Unchecking all checkboxes through JavaScript

Suppose we have 10 check boxes ..& checkboxes ID are chk1,chk2,chk3...

<script>

function selectOnlyThis(id) {
    for (var i = 0;i <= 10; i++)
    {
        document.getElementById("Chk" + i).checked = false;
    }
    
}

</script>

Call this function on a button click.
