How can i handle the maximum of characters, that user has entered from keyboard on native.newTextField?
Use string.len() to get the number of characters the user entered with a runtime listener.
[lua]
function checkMaxChar()
local maxChar = 10
if string.len(event.text) <= maxChar then
– Do something
print(" String is less or equal to 10 char")
else
– tell user input text is too long with an alert…etc
print(" String is too long")
end
end
Runtime:addEventListener(“enterFrame”, checkMaxChar)
[/lua]
or if you just want to check the maxChar at the “submitted” phase then you could just
[lua]
if string.len(event.text) <= maxChar then
– string is good, do something with it
else
– string is too long, fix it, show an alert, clear the textfield or something…
end
[/lua]
Thank you, will try it!
