How do i store a session array inside jquery variable? Laravel / Jquery

Question

I'm trying to store a session array inside a jquery variable.

My code:

<script>
@if(session()->has('zoektermen'))
    var zoektermen = '{{ session()->get('zoektermen') }}';
    console.log(zoektermen);
@endif
</script>

Putting in session inside controller:

if(isset($_GET['searchquery'])) {
    $searchquery = $_GET['searchquery'];
}

if(session()->has('zoektermen')) {
    session()->forget('zoektermen');
    session()->put('zoektermen', $searchquery);
} else {
    session()->put('zoektermen', $searchquery);
}

But i'm getting an error because {{ }} expects a string and not an array.

htmlspecialchars() expects parameter 1 to be string, array given

What is the correct way to store the array from the session into a JS array?

You can not use php array to JS. You have to convert to JSON and then you can use there — Pankaj Makwana

Then you likely did not do it correctly ... encoding any data object as JSON will give you a string value. — C3roe

Your code is not sufficient to solve this issue, paste the whole or relevant code from which the errors causes. — Rohan Kumar

Do like this

<script>
@if(session()->has('zoektermen'))
    var zoektermen = '{{json_encode(session()->get("zoektermen"))}}';
     zoektermen= $.parseJSON(zoektermen);
    console.log(zoektermen);
@endif
</script>

I thing it will help you.

Use php json_encode and decode in JS to get PHP array in JavaScript

<script>
@if(session()->has('zoektermen'))
    var zoektermen_json = "{{ json_encode(session()->get('zoektermen')) }}";
    var zoektermen = JSON.parse(zoektermen_json);
    console.log(zoektermen);
@endif
</script>
