      {
     window.open("enter code heregurrantor/old",
    "mywindow","location=1,status=1,scrollbars=1,width=700,height=700");
    }
    </SCRIPT>
    <a href="javascript: openoldgurantorwindow()">Click to view old Guarantors</a> 

Thank you in advance.

Answer 1

You can pass id or any other parameter as query params like shown below:

function openoldgurantorwindow(id) {
    window.open("http://example.com?id=" + id,
            "mywindow", "location=1,status=1,scrollbars=1,width=700,height=700");
}

And can be retrieved at next page in PHP code in $_GET variable.
