Hi,
I am working with Navigation Bar in my APP. How can I reload the card "Home" every time this card will be opened from stack?
I tried with on openstack and on opencard, but it will not reload
Reason for this: I want to show random exhibitors to the users...
Thank you very much,
Stefan

Hi Stefan,
when you navigate to a card its "pre-/opencard" messages are triggered!
What did you script so far and where did you put the script(s)?

Hi Klaus,
sorry, I am afraid, but I don't get you. I have put the script
to my widget "Browser". I tried first on the stack itself, but got an error message as "Field" could not be found on the other cards...
All the best,
Stefan

Code: Select all
on opencard
send "loadPreferences" to this stack in 10
end opencard
command loadPreferences
put readPreferencesToXMLTree() into tTree
if tTree is empty then
exit loadPreferences
end if
end loadPreferences
private function readPreferencesToXMLTree
put random(4) + 1 into rNumber
put url("URLTO/getexhibdata.php?messe=" & rNumber) into tXML
put revXMLCreateTree(tXML, false, true, false) into tXMLTreeID
put revXMLRootNode(tXMLTreeID) into tRoot -- "messen"
put revXMLFirstChild(tXMLTreeID,tRoot) into tResponse -- "messe"
repeat while "xmlerr" is not in tResponse
put revXMLNodeContents(tXMLTreeID, tResponse & "/id") into tID
put revXMLNodeContents(tXMLTreeID, tResponse & "/messe_1") into aRecords[tID]["messe_1"]
put revXMLNodeContents(tXMLTreeID, tResponse & "/vimeo") into aRecords[tID]["vimeo"]
put revXMLNextSibling(tXMLTreeID,tResponse) into tResponse
if tResponse is empty then
exit repeat
end if
end repeat
put aRecords[tID]["vimeo"] into tVideoURL
set the url of widget "Browser" to tVideoURL
put aRecords[tID]["messe_1"] into field "Field"
end readPreferencesToXMLTree
All the best,
Stefan
Re: Force Card to reload every time it will be opened
Does that help:
Code: Select all
...
put aRecords[tID]["messe_1"] into field "Field" OF CARD "the one with the field" ## OF STACK "If in another stack"
## :-)
