Problem - Parsing information using onchange in two select fields
|
|
| please-answer-here 2005-05-30, 5:52 pm |
| Scenario:
I'm having an asp page with a form with an action pointing to itself. The
reason for that, it that the asp page depending on changes in any of two
select fields with data from 2 different databasetables are going to
populate a third select field.
what I have done is something like:
response.write("<select size=""1"" name=""fabrikat""
onchange=""document.forms[0].submit()"" >")
response.write("<select size=""1"" name=""type""
onchange=""document.forms[0].submit()"" >")
what I very much would like was a way that I in the asp page when it got
reloaded could check which of the "select" fields have generated the submit.
If I had used submit buttons I could have used a querystring, but as the
reload of the page sholud happen transparent to the user it is out of the
question
regards
Henning

Try
<input type="hidden" name="WhichSelect">
<select size=""1"" name=""fabrikat""
onchange="document.forms[0].WhichSelect.value="fabrikat";document.forms[0].submit()">
and for the other one:
onchange="document.forms[0].WhichSelect.value="type";document.forms[0].submit()">
Hope that helps
