High,

I have a Long free text question which Shows an Image, on clicking the Image it gets enlarged.



Here is the code:

<script language="javascript">
<!--
var AngezeigteBreite = 50;
var GespeicherteBreite = 0;

function BildAnpassen(Bild)
{
if (Bild.width > AngezeigteBreite || GespeicherteBreite > AngezeigteBreite)
{
if (Bild.width == AngezeigteBreite)
{
Bild.width = GespeicherteBreite;

}
else
{
GespeicherteBreite = Bild.width;
Bild.style.cursor = "pointer";
Bild.width = AngezeigteBreite;


}
}


}
//--></script>




Want I want is that the Images Needs to be enlarged before answering the question.
Can anyone be of help please?

Thanks and regards

Andrea

You missed this part.
Code:
<img onClick="BildAnpassen(this)" onLoad="BildAnpassen(this)" src="/bild.png" title="Klicken zum Vergrößern/Verkleinern">

First I would like to ask the others on this board if there isn't a better zoom/lightbox image script (e.g. jquery plugin), which is suited to surveys? What about dimsemenov.com/plugins/magnific-popup/ ?
Problem is finding an maintained plugin.

Not sure if a 100% errorprone solution is possible, but you might add a hidden question and force an answer. When the image is clicked a certain value is written into that hidden question.
As long as the hidden question is not answered the image has to be clicked.

Since I am not the biggest javascript fan I cannot provide you a readymade solution.
Perhaps my silly lines will provoke a more sophisticated answer from the household user names of this board.
