Solution

Try this

<script>

function sent_date()
{
 sdate=document.getElementById("Sdate").value;
 edate=document.getElementById("Edate").value;
 window.location=('purchaseReportExcel.php?Sdate='+sdate+'&Edate='+edate);
}
</script>

<a href="#" onclick="return sent_date();" title="purchase report"/><img src="excel3.png" title="purchase report"/></a>
