You'll have to echo it directly into the function or one of the parameters...or pass it as a parameter in an AJAX method.
passing it directly gives me a parse error, passing it as an ajax parameter i first have to get it from my php script to javascript... explaining a little more below is what i wish to do.Quote:

echo "<span onclick=pass_json($param)";
I am fetching data for from the data base which contains names and addresses and other details of people. On the left i have a scrollable menu of all those people with their names, so as soon as a name is clicked i want their details (address etc) displayed on the right side without any page load.... yes i do know i can do this using ajax but i donot wish to transact with server as i have already fetched al that data.
A few minor parts left off in your code...Anyway, the problem you are facing is most likely quotes inside of quotes. A simple HTML entity replace fixes the issue.
PHP Code:<script type="text/javascript">
function pass_json(param) {
while (param.search(""") > -1) {
param = param.replace(""", "\"");
}
alert(param.toString());
}
</script>
<?php
$arr = array(1 => 'john', 2 => 'smith', 3 => 'kerri');
$param = json_encode($arr);
?>
<span onclick="pass_json('<?php echo htmlentities($param); ?>');">Test me!</span>
Ok but how can i access it in the javascript, lets say my array was as belowQuote:

param.1[0].name// which gives me an error.
what i wish to accomplish is pass uniqe id as the key from the database and all the subsequent data that i may have, so when a user clicks on a left navigation menu alli have to pass is this json formatted data and the unique id and using jquery i could place that content on the right div.
Firstly i wish to know how i can access that json data in javascript
secondly is this the right approach to what i wish to accomplish or is there a better way.
So then why are you using JSON? You should just output the data as an associative array in JavaScript.
but how can i pass an array from php to javascript.Quote:

I could do that, but thought that wasnt a good way of doing.
Anyways Is it not possible for me to access that data how i mentioned previously using JSON in javascript.
how can i out put the data as an assosciative array in js, does it work exactly like that as php ?
PHP Code:<script type="text/javascript">
var myArray = new Array();
<?php
$arr = array(1 => 'john', 2 => 'smith', 3 => 'kerri');
foreach ($arr as $k => $v) {
?>
myArray["<?php echo $k; ?>"] = "<?php echo $v; ?>";
<?php } ?>
</script>
