Thank you very much Mike.
Thanks to the wiki article I see more clearly where I have to tend toward.
but stil...l the aim is to launch a netwebsource procedure directly on the onclick= of the button tag.
for instance this solution
onclick=”window.open(’BrowseCustomers’,’_blank’)”
opens a window
and in this one:
p_web.CreateButton('submit','Subscribe','','SmallButton',loc:formname,p_web._MakeURL(clip(loc:formaction)&'?'&p_web._noColon('RPTIR:InstanceID')&'='& clip(loc:field) & '&PressedButton='&clip('Subscribe'))
the MakeURL function redirects our page to a new page (the netwebsource which contains the procedure to execute).
But I think that a javascript funtion which redirects immediatly my page to the previous page with a "window.location="frame_src.htm"" on the onload() might work.
I'll let you know.
thank very much again and good luck with your buttons
Philippe.
