Hey guys,

thank you for your response! After a while of try & error and your help, I just have my spamcheck running!

I've found this and use it to shuffle my array (thank you JSG!):

function shuffle(array) {  var m = array.length, t, i;  while (m) {    // Pick a remaining element…    i = Math.floor(Math.random() * m--);    // And swap it with the current element.    t = array[m];    array[m] = array[i];    array[i] = t;  } return array;}  var spamcheck = [       {f: 'Question A',        a: 'ANSWER A'},       {f: 'Question B',        a: 'ANSWER B'},       {f: 'Question C',        a: 'ANSWER C'}   ];   shuffle(spamcheck);

next I get the anwser in an hidden field of my formular, base64 decoded:

<input class="kissmebaby" name="chk-hidden" id="chk-hidden" type="hidden" value="'+Base64.encode(spamcheck[1].a)+'" />

And finally I check, if the typed answer matches the right answer, all lowercase:

var rightanswer = document.getElementById("chk-hidden").value;var x = document.getElementById("answerfield").value;var givenanswer = Base64.encode(x.toLowerCase()); // note, BASE64.encode (references to a function)if (givenanswer !== rightanswer) {  document.getElementById('answerfield').style.background = "#f9ef9e"; // tell the user there is something wrong...   } else {   //go to the serverside php-script viá ajax}

and this is it. Thanks for putting me on the right way!

PS: this works for me like a charm, may it be there is something "too much" in this shuffle-function, but I'm glad it works now and wouldn't change anything, the performance(s) of the entire script(s) on my website is ok..

PPS: @davej: thank you too, I gladly abandoned the idea to solve this viá the indexies!

Hello Folks,

I just wondering why JS cannot handle associative arrays like php does. Ok, after a while of investigation I stuck with a little code now. Once I've written a simple q&a spamcheck for my contact form in php, hence, I try to adapt it to a js contact form: It's a beautiful pop-up form that costs me 7 dollars, I was just missing that in this script I bought one week ago comes with NO spamcheck functionality, so I would like to build it on my own, maybe with your help?

I know that there are no associative arrays in js. My basement is this code:

  var questions = {       'The color of the sky?': 'blue',       'Abraham...': 'lincoln',       '10 minus 2, plus 3..': '11',       'Rupert the rednose...': 'reindeer'   };

So, next I just need to count the "keys" or array-entries, object parameters, you name it.

Finally I want to shuffle the indexies and return one single question.

To count the "array" I tried this:

var count = 0; // initializefor (var i in questions) { if (questions.hasOwnProperty(i)) { ++count; } }var min = 0; var max = count;alert(count);

...and it works like a charm! My problem is now the indexies e.g. the KEYS of this Object... I don't know how can I shuffle them, and even put out then. Any suggestions to this?

Maybe something in this direction:

var qsingle = shuffle(min, max);alert(qsingle);

But the output is nothing, the script even breaks... But works fine in php! Any help would be greatly appreciated!
