Show every item (a picture) of a question separately for 30 sec

Question

Hi there,

I have a question which consists of picture items which have to be rated on a 4-level-scale. The pictures (itemtext) should be visible for 30 seconds and then be hidden (but the scale has to stay until the rating has occured).

I found that I can show a single item with the php-function question() but did't find out how to hide the itemtext after 30 sec. Something with javascript I suppose? Is it possible to only hide the itemtext but leave the scale itself?

Thanks a lot

I found that I can show a single item with the php-function question()

That is not exactyl what you need. There is PHP code that runs on the server (between the pages) and JavaScript code that runs in the browser. The latter is what you need for timing etc.

Please read this manual: Timer: Go Onto Next Page Automatically and Timer: Show the 'Next' Button After a Certain Period of Time

And then read that manual: Immediately Show Questions when a Certain Option is Selected

By combining timers (from the frist two manuals) and visibility (from the second manual) you can easily build what you need.
