Is there anyway to do this?

I want to alert the object in javascript, but I can't find a function that will do this. I want to do something like print_r() but for javascript.

I don't know of any way to do that.  But if you are having trouble debugging javascript, use the firebug plugin for firefox, it can help lotz.

As in

 

<?php 
$var = array('first','second');
?>
<script>
alert(
<?php
print_r($var);
?>
);

Something similar maybe, as it is untested.

It won't work like that because PHP is executed on the server before sending any response back to the browser.

 

What you might do is set a javascript timer that uses an Ajax call query a PHP script at intervals

Exactly that's why it will work, try it, i admit that one might not work. But this one will

<?php
$var = "test, proving you wrong";
echo "<script>alert('".$var."');</script>";
?>

 

Unless he is trying to do something to make php interact with the JS after the page has loaded, but he didn't say he did. If you do then look at ajax.

Not sure why this is in the PHP section, but I am pretty sure you can do the toString in javascript.

 

<Script type="text/javascript">
var myfriends=new Array("John", "Bob", "Sue")
alert(myfriends.toString());
</script>
