读取JavaScript中的会话变量

Question

How can I read the session data set in PHP from Javascript. I tried the following code, but it doesn't work.

<?php
session_start();
$_SESSION['test'] ="orange";
?>

<script>
var username = '<%= Session["test"] %>';
alert(username );
</script>

Thanks for your help.

Answer 1

use:

<script>
<?php echo "var username = '".$_SESSION["test"]."';";
alert (username);
</script>

Answer 2

Just echo it out:

<?php
session_start();
$_SESSION['test'] ="orange";
?>

<script>
var username = '<?php echo $_SESSION["test"]; ?>';
alert(username);
</script>

BTW, you used ASP.NET inline expression tags. You can use <?= ?> for PHP if you have short tags enabled.

Answer 3

Following are your mistakes

1. You have written Session["test"] instead of $_SESSION['test']
2. you are using % symbol instead of ?

Try this:

<?php
session_start();
$_SESSION['test'] ="orange";
?>

<script>
var username = '<?= $_SESSION["test"] ?>';
alert(username );
</script>
