如何使用ajax在LARAVEL中获取新的CSRF令牌

I have created a form which is having a lot of fields and user can create an unlimited field in it. If a user spends more time on it CSRF token get expires and when he clicks on the submit LARAVEL return the error CSRF token mismatch. So how can I get new CSRF token by using ajax call so I can update the CSRF on a regular time of interval? I can not refresh or reload the form.

    Just add this to your script

    <script type="text/javascript">
                $.ajaxSetup({
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
                    }
                });
    </script>
    

    And make sure you have added token to your meta tag like below.

    <meta name="_token" content="{!! csrf_token() !!}" />
    

    I hope this will work for you.
