Ajax is not working my plugin

<?php
function example_ajax_enqueue() {
  // Enqueue javascript on the frontend.

  // The wp_localize_script allows us to output the ajax_url path for our script to use.
  wp_localize_script(
    'example-ajax-script',
    'example_ajax_obj',
    array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) )
  );
}
add_action( 'wp_enqueue_scripts', 'example_ajax_enqueue' ); ?>
     <script type="text/javascript">
  var ajaxurl = '<?php echo admin_url("admin-ajax.php"); ?>';

jQuery(document).ready(function($) {
   $('body').on('change', '#assign', function() {
    // We'll pass this variable to the PHP function example_ajax_request
    var fruit = 'Banana';
     
    // This does the ajax request
    $.ajax({
        url: ajaxurl, // or example_ajax_obj.ajaxurl if using on frontend
        data: {
            'action': 'example_ajax_request',
            'fruit' : fruit
        },
        success:function(data) {
            // This outputs the result of the ajax request
            console.log(data);
        },
        error: function(errorThrown){
            console.log(errorThrown);
        }
    });    }); 
              
});
</script>
<?php 
function example_ajax_request() {
 
    // The $_REQUEST contains all the data sent via ajax
   echo "DSfds";
     
    // Always die in functions echoing ajax content
   die();
}
 
add_action( 'wp_ajax_example_ajax_request', 'example_ajax_request' );
 
// If you wanted to also use the function for non-logged in users (in a theme for example)
add_action( 'wp_ajax_nopriv_example_ajax_request', 'example_ajax_request' );
