I know this can be done - I just don't know how to do it.

Anyone have a simple implementation for storing and displaying the results of something like this:

Math.random().toString(36).slice(2)

in a question's answer?

As always, any assistance is appreciated.

I'm still at it - no avail! I've tried many snippets like this.

<script>
$(document).ready(
function(){
// Find a random number (here between 1 and 4)
var randNumber = Math.floor(Math.random()*4 + 1);
// Save the number as answer of this question
$('input#answer527453X176X1255').val(randNumber);
});
</script>

Anyone have thoughts on why this doesn't work? the question type is short text.

Still at it. This is how I spend my Saturdays.

alert('test') works and everything. I'm beggin' here.

So, just in case it helps anyone. This took forever, and it's somewhat of a workaround, but it gave me the desired result. No javascript - all expression manager.

I divided:
{floor(rand(100000,999999))} by
{time()} and rounded up to get my random number.

In:
{ceil(time()/floor(rand(1000,9999)))}

Then I used {substr("abcdefghijklmnopqrstuvwxyz", -rand(1,26),1)} to get random alpha characters.

The final implementation, in which I cleverly removed "i", "l" "o", and "O" can be seen here:
{join(ceil(time()/floor(rand(1000,9999))), substr("abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ", -rand(1,48),1), substr("abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ", -rand(1,48),1))}

Placing this in the source of your survey item will yield something like this:
231387Cp


Enjoy.

thanks for sharing..
=>related previous thread: Generate Unique PIN for user

So how can I store it? I want to recall the same alphanumerical pin in my email template. The number got replaced if I use INSERTANS.

Thanks

Place it in an equation type question and then reference the question code in the email - {Qcode} - www.limesurvey.org/manual/Expression_Man...#Access_to_Variables

@David/dweisser : great thanks and great code here

you didn't add a is_empty test ? To do the number only one time (based on time) ?

Thanks I tried. In the email, I got the same number using INSERTANS and {Qcode}. But it is not the same one in the survey question.

As Denis says, you probably need to add a "is_empty test". Because the random numbers are triggered everytime the question is called if you don't do it. So first check if the question is empty, then generate the code. This means the code will only be generated once and when you access the code via EM it will always be the same.

Then finally :
But we can write like this:
@dweisser : if you found some time for our workaround in manual ? Or a LS EM example file
