PHP variable into javascript

[idy]

Hello !

I have the following JS function

[code]function test(id) {
var result = '<? echo $array[' + id + ']; ?>';
alert(result);
}[/code]

which does not send anything. How is it possible to send the javascript variable id to the PHP variable (array) $array ?

Thanks a lot.

[code]$array[' + id + '];[/code] What's this meant to be?

you are mixing js and php there buddy!

PHP will stop running once the page has been served to the client - php can do no more after that until the next request is sent.

you wil have to populate and array explicitly in js usign the php array you have constructed and then use id to traverse it.

OK thanks a lot.

You could use this to get the point:

[code]<?php
$id = "5";
echo "<a href='#' onClick=\"alert ('$id');\">Get it</a>";
?>[/code]

Actually the variable $array is already used in my PHP script before writing the JS function.
If I write :
[code]
var result = '<? echo $array[0]; ?>';
[/code]
I do have the content of $array[0] into result.
The only thing I am trying to do is to retrieve the JS variable id instead of the hard-coded value 0 into $array. Or is still the same problem ? Thanks !

For that you need to look at AJAX.
