Question

I have a hidden div in a ctp file.

<div id="UserId" style="visibility:hidden;">
    <?php 
        $UserId = $app['Auth']['User']['id'];
        echo $UserId;
    ?>
</div>

I need to get this $userId value in a .js file.

var user_id = $("#userId").val();
alert(user_id);

But I got empty value. Please help…

I tried with var current_user_id = $("#userId").html();
but it shows the value in the center of the alert box and if i use that value in if condition, it does not return true for the condition.

For eg: say user_id value is 5.
A = 5

if (A == user_id){
  alert(1);
} else {
  alert(2);
}

It always returns 2.

Either get the value using .innerHTML or use an <input /> tag to store your value for example:

$UserId = $app['Auth']['User']['id'];
echo "<input type = 'text' 
             id = 'UserId' 
             style = 'display: none;' 
             value = '" . $UserId . "' />";

you see <div> tags don’t have values
