How to run my code only once in a custom menu walker file?

    Hi, I’m creating a theme and made custom menu walker class files, but I added an inline <script> in the walker file and it displays the <script>…</script> as many as the number of the file are looped by core like this:

    <script>…</script>
    <script>…</script>
    <script>…</script>
    <script>…</script>
    <script>…</script>
    …

    ‘…’ part is what I intended, but I want to print <script> and </script> tags only once like this way:

    <script> => print only once at the very first time in the loop
    …
    …
    …
    …
    …
    </script> => print only once at the very last time in the loop

    Is it possible to do it in the custom menu walker file?
    Please help me! Thank you.

    Do you want to put your JS code into a JS file and then enqueue that in your functions.php file?

    No, it must be added inline in the walker php file directly, because it includes php ID-related code for every looped menu item elements.
    So it must be inside the looped PHP file, and I want for the only <script> open/close tags to render only once but the contents inside should be looped. Could I get any variables related to this walker menu item loop from the core?

    my_custom_walker.php ==> it’s the looped file
    class My_Walker_Nav_Menu extends Walker {
    .
    .
    .

    <script> ==> only once
    jQuery {
    . . . this is the code that should be run on every items here . . .
    jQuery(‘#menu-item-<?php echo $item->ID; ?> …
    }
    </script> ==> only once
    .
    .
    .
    }
