Why not just setting a javascript variable with the json content you retrieved like this:
<?php
$response = "YOUR JSON RESPONSE";
?>
<script type="text/javascript">
var json = "<?php echo json_encode(json_decode($response)) ?>";
</script>
Be sure that you escape $response the correct way to prevent corrupting your javascript.

function func1()

try

addedVariable = addedVariable;
alert('can only add the script once');
}
catch(ex)
{
var sc = newEl('script');
sc.appendChild( newTxt('var addedVariable = 100;' ) );
document.head.appendChild(sc);
alert('script element with variable added');
}
}
function func2()
{
try
{
alert("value of 'addedVariable' = " + addedVariable);
}
catch(ex)
{
alert("hit the first btn, then try again");
}
}
