Hi, Rita,
you may use this javascript to select the 8 out of 10
Insert it into a question of type "shorttext" (eqImage)
Code:
<script type="text/javascript" charset="utf-8">
function shuffle(array) {
var currentIndex = array.length, temporaryValue, randomIndex;
// While there remain elements to shuffle...
while (0 !== currentIndex) {
// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex -= 1;
// And swap it with the current element.
temporaryValue = array[currentIndex];
array[currentIndex] = array[randomIndex];
array[randomIndex] = temporaryValue;
}
return array;
}
$(document).on('ready pjax:scriptcomplete',function(){
// Fill the array
var arr = ["A","B","C","D","E","F","G","H","I","J"];
// Shuffle the array
arr = shuffle(arr);
anumbers = arr.slice(0,8).join('');
$('#question{QID} input[type="text"]').val('#'+anumbers);
$('#question{QID}').hide();
});
</script>
You will get something like #CEFAHBDJ
Your questions all get the same randomozation group name and the conditions
strpos(eqImage,"A")>0
strpos(eqImage,"B")>0
...
