I have got an issue with passing a json object to ajax at prototype.
here is the situation:
PHP: 

<?php
    $a = array(k1=>v1, k2=>v2);
    $a = json_encode($a);
?>//JS 
<script>
    var a_js = <?= $a ?>
</script>
<?
    echo '<input type:"button" onclick='save(a_js) value='save js''>';
?>

JS 

function save(a_json) {
    AJAX_ACTIONS_URL = 'ajax_action.php';
    params = {
        act: 'save_filters_status',
        a_json: a_json
    };
    new Ajax.Request(AJAX_ACTIONS_URL, {
        method: 'post',
        parameters: params,
        onSuccess: function (transport) {
            alert(transport.responseText);
        }
    });
}

Ajax_actions.php

if(var_post('act')=='save_filters_status') {
    $x = explode(',',var_post('a_js'));
    print_r($x);
}

Now, I don't see any post for a_js at fire fox, there is no response from the ajax, and I am a bit lost, thanks for your help.. Notice I work at JavaScript prototype frame work..

Your echo'd button has some faulty quote nesting:

 echo '<input type:"button" onclick='save(a_js) value='save js''>';

Should be: 

 echo '<input type="button" onclick="save(a_js)" value="save js">';

I'd add that type:"button" isn't valid either. – Ranty Dec 19 '12 at 14:05
@Ranty: Derp, how could I have missed that! Thanks! – Cerbrus Dec 19 '12 at 14:15
i change it, but still he cant the json, when using alert at the js part i get (object object) – Amir Maman Dec 19 '12 at 18:37
@AmirMaman: Apparently transport.responseText is a object, then. Can you console.log() it, to see it's actual contents? – Cerbrus Dec 20 '12 at 7:34

  <script>
    var a_js='<?=$a?>';

  <?
