PHP Variable from Separate file jQuery -

im trying grab variable separate php file jquery if statement (i'm wondering how can import php file jquery)

(the script count characters in textarea)

current code:

$( document.body ).ready(function() {     $('#message-input').live('keyup',function(){         if ($message == 0) {             $('#message-count').html('enter @ least 14 characters');         }          var count = ($(this).val().length);         if ($message < 20 && $message > 1) {             $('#message-count').html('enter atleast more ' + count + ' characters');         }          var remaining = 1000 - ($(this).val().length);         if ($message > 20) {             $('#message-count').html(remaining +' more characters go');         }     }) }) 

if jquery codes written inside php file, can this

// inside yourfile.php  // pass php var js var var message = <?php echo $message ?>;  // can use var message here... $( document.body ).ready(function() {     $('#message-input').live('keyup',function(){         // if ($message == 0) {         if (message == 0) {             $('#message-count').html('enter @ least 14 characters');         }          var count = ($(this).val().length);         // if ($message < 20 && $message > 1) {         if (message < 20 && message > 1) {             $('#message-count').html('enter atleast more ' + count + ' characters');         }          var remaining = 1000 - ($(this).val().length);         // if ($message > 20) {         if (message > 20) {             $('#message-count').html(remaining +' more characters go');         }     }) })
