Hello All,
I'm trying to display records in a table, that has a button at the end
of each row, that calls a JavaScript popup to confirm the delete.
I'm stuck and would appreciate any help anyone can offer.
Some of the code is attached.
Thanks!

<script type="text/javascript">
<!--
function confirmation() {
var answer = confirm("Delete Record?")
// how can I pass the record ID from python to javascript?
// I tried something like ... recno = "{{=r.id}}"
recno = '48'
if (answer){
// delete the specified record number
alert("Deleting Record Number# " + recno )
window.location = "http://IP-ADDRESS:8000/appname/
controller/delete/" + recno;
}
else{
alert("The record was NOT deleted")
}
}

{{# tboffice.id tboffice.fdesc tboffice.fprice }}

{{ for r in recs: }}
{{ price = '%.2f' % r.fprice }}
{{ rec_id = '%04i ' % r.id }}
{{ d = r.fdesc }}

f="delete/"+str(rec_id) ))) }} </td> <td> <form> <input type="button"
onClick="confirmation()" value="Delete"> </form> </td>
</tr>
{{pass}}

onclick="confirmation('{{=r.id}}');"
Then just accept the parameter in your JS function and handle it
there, something like
function confirmation(recno) {
...
-- Julio

hey... web2py does this automatically if you use an input checkbox
with class="delete". No JS needed.

Thanks Massimo,
It's GREAT to know that web2py can do that, but I thought I should learn about passing variables between python and web2py using JavaScript.
