How do I use a custom filed value in an external javascript? I'd like to use a custom field already stored for a post that is an url in an external javascript

<script type='text/javascript' src='.js'></script>

in order to open a new window

onclick="window.open('MY_CUSTOM_FIELD_VALUE');"

I tried to add

global $post; $cf = get_post_meta( $post->ID, 'my_custom_field', true );

but it doesn't work. Thanks for your help.

• You might be able to do with Ajax. You have the control of the 'external JavaScript' ? – sri Commented Mar 24, 2014 at 10:17

I had a similar problem using custom field values in a widget that used JavaScript. I wrote a tutorial explaining it. Try this code:

<?php 
global $post;
$cf = get_post_meta($post->ID, 'my_custom_field', true);     
?>

<button onclick="window.open(<?php echo json_encode($cf); ?>);">Click me</button>
