[thelist] Calling a function in ASP from a link

[Richard Bennett]

hi,
Ok, you want to call a function on the server, from the client, without
reloading the page, or using a frameset.
This is one way:

<script>
    var Sender=new Image()
    var custID='100 bookmark this'

    function updateDatabase(){

Sender.src='http://www.server.com/cgi-bin/script.asp?custID='+escape(custID)
        return false
    }
</script>

and then:
< a href="javascript:#" onclick="return updateDatabase()">Bookmark this
record</a>

That should do it.
Taken one step further, the server-script can redirect to an image, if the
update was performed successfully, or to an .html page if not.
Then your image will trigger an onload event for success, and an onerror
event for an error.
you would listen for that like this:

Sender.onerror=function(){alert("something went wrong")}
Sender.onload=function(){alert("All OK")}


Cheers,
Richard.
