Get PHP variable to javascript

Question

I cant seem to find the answer for this one. I need to grab a PHP variable and insert it into javascript.

Here is an example of what I have in the body of a PHP page:

<script type="text/javascript">
$(document).ready(function(){
    $('#button').click(function() { 
        var info = "<?php Print($info); ?>";
        $.post($("#frm1").attr("action"), $("#frm1").serialize(), function () {
        alert(info);
        });
    });   
});
</script>

<?php
    $info="some info";
?>
<form  id="frm1" method="post" action="somepage.php">
<input name="Text1" type="text" />
<input id="button" type="submit" value="submit" />
</form>

So the problem is that the alert pops up but doesn't echo the $info string. Obviously i'm missing the right way to grab a PHP variable. Please help.

Answer 1

If the php variable is visible inside the inner HTML, you could do something like this to grab the variable:

HTML:

<span class="variable-content"><?php echo $variable; ?></span>

jQuery:

var php_variable = $(".variable-content").text();
alert(php_variable);
