Kod statistik trafik tapak web dilaksanakan dalam kemahiran javascript_javascript

Tapak web biasanya mempunyai alat statistik trafik Terdapat banyak alat yang cekap dan praktikal, dan ia sangat tepat. JavaScript praktikal juga boleh melaksanakan fungsi ini walaupun ia tidak setepat yang biasa digunakan di Internet, ia mencapai fungsi tertentu Berikut adalah contoh kod yang berminat:

Tiada lagi perkara karut, saya hanya akan menghantar kod js untuk anda.
