How to add a redirect Javascript code to the child theme

Morning

You could put the code in the google analytics section under Theme Options > Google Services.
I’ve used that section to put marketing automation tracking codes and google codes and they work fine.

Or you could add a function to the functions.php

function add_custom_target(){
?>
<script>
document.addEventListener( ‘wpcf7mailsent’, function( event ) {
location = ‘http://example.com/’;
}, false );
</script>
<?php
}
add_action('wp_footer', 'add_custom_target');

Be very careful with the last option as any errors in functions.php could throw up a 500 internal error and you’ll need ftp or cPanel access to reverse the changes.

Try the first as that is a safe option :) Once done right click on any page of your site and click view page source. Search the source code for the script to see if it has worked.

Hope that helps
