Code de statistiques de trafic de site Web implémenté dans les compétences javascript_javascript

Les sites Internet disposent généralement d’outils de statistiques de trafic. Il existe de nombreux outils efficaces et pratiques, et ils sont très précis. Le JavaScript pratique peut également simplement implémenter cette fonction. Bien qu'il ne soit pas aussi précis que celui couramment utilisé sur Internet, il remplit certaines fonctions. Voici un exemple de code qui peut s'y référer :

Plus de bêtises, je vais juste poster le code js pour vous.
