i++;
}
else
{
return;
}
}
but I cant do the function... How must it be? Sorry about my english
For Question 1 you want to show the first image and so on? question parameter is the Number of the question? first hide all images, then show the image (question number minus 1 - index 0 based).
function resim(question) {
// hide all
$("#background img").hide();
// show by Num
$("#background img").eq(question-1).show();
}
Be sure the div background has display: block and not none.
If the div#background
contains all your img
tags and div#background
is set to display:none;
then even if you set the images to show, they won't display because their parent element is set not to display.
You'll have to set the div#background
to show and the individual img
tags to hide and show the individual images as needed.
An alternate function you may want use could look like this:
function resim(question)
{
$("#background img").hide();
$("#background img:eq("+question+")").show();
}
