doubt on values of variables passed to a function

[Vidya_tr]

Can I pass a  variable declared in php to a function written in javascript??

[Fruct0se]

You can only do this if the php is run prior to your javascript code, you could echo the variable to an input field then retrieve it using javascript.

 

So you could <?php echo '<input type="hidden" name="javavariable" value="'.$yourvariable.'">'; ?>

 

Then in javascript use

myvar = document.getElementById("javavariable").value;

 

Hope this helps.

<?php     
$user_id = $_GET["uid"]; 
?> 
<script type="text/javascript">
var user_id = <?php echo($user_id);?> ;
alert("Your user ID is:" + user_id);
</script>
