I have Javascript code that I output inside of a PHP file, but put
variables inside the javascript block. I am getting a weird error:
<?php
function SomeFunction()
{
?>
<script type="text/javascript">
parentValue = <?=$parentValue?>;
</script>
<?
}
?>
I get an error over the '<?' of the '<?=' expresssion in the javascript
block saying: Syntax error on tokens, PostfixExpression expected instead
Anyone know why this is?
Thanks,
Micah

That didn't make a difference.

They are integers, but it doesn't matter since I'm just passing them to
a PHP script with AJAX. This actually worked, but I have a new problem:
if (parentValue)
{
<?php echo $function;?>
}
gives me these errors:
Multiple annotations found at this line:
- Syntax error on token "<", invalid Expression
- Syntax error on token "?", invalid Expression
- Syntax error on token ">", FullPostfixExpression expected after this
token
- Syntax error on token "echo", : expected
- syntax error, unexpected 'EOF'
It seems like the Javascript parser has trouble with the PHP inside the
javascript, even though the javascript is in a PHP file.

I might have to try this instead.

The name of a xajax function. This is while editing, not running that I
get the error.

I'll have to do that. I just wanted to make sure that I wasn't missing
a config setting before filing a bug.

I have pure Javascript functions in a separate file, but it happens to
be that 65% of this function is generated from PHP variables, so I am
outputting it inline.
Thanks,
