php in javascript

[juicy]

I put a function call in checkbox onclick event, and want to append text to
a variable. But if I get value from a php variable, I get error on page,
but if I put output = output + "text", it works well. Can anyone help?
Thanks

function getS (id){
var output = "";
if (document.getElementById("id").checked)
{
output = output + <? echo $text; ?> ;
}}

Where do you expect the PHP code to be evaluated?

thanks for your reply. I put the php code above the function. I found that
if $text value is short text, the script perform well, but because of
$text value is a paragraph of text, it caused error occured. But I still
do not know why this error happen.

<script language = "javascript">
<?php $text = "test1"; ?>

function getS (id){
var output = "";
if (document.getElementById("id").checked)
{
output = output + <? echo $text; ?> ;
}}
</script>

Please quote context and attributions in your reply, not everyone uses
google.

In what context is this evaluated? Is it in a php file?
<script language = "javascript">
Don't use this, use type="text/javascript".
<?php $text = "test1"; ?>

function getS (id){
var output = "";
if (document.getElementById("id").checked)
{
output = output + <? echo $text; ?> ;
}}
</script>

Don't use this, use type="text/javascript".

Yes, I have changed to it, but the problem still same.

Yes, it is a php file.

Then it's time to pass the ball to the PHP list.

So if $text contains the text: text

Then you are outputting something like:

output = output + text;

Note how this is different to the

output = output + "text";

you had before.

Home is where the ~/.bashrc is

output = output + <? echo (" \' $text \' "); ?>

There's something you forgot of: line breaks. A paragraph is being
output like that:

output = output + "this is your text

this is your next line";
Which will result in a "unterminated string" error. You must replace,
using PHP, any \n by a literal "\n", which will result:

output = output + "this is your text\nthis is your next line";
Leaving the line-break to be handled by JS.

Not at all.

output += "<?php echo addslashes($text); ?>";
