คำเตือน

หากไม่มี base หรือไม่มีการกำหนด URL พื้นฐานด้วยการตั้งค่า href ของ base แล้ว เบราเซอร์จะใช้ URL ของเอกสารปัจจุบันเป็นพื้นฐานสำหรับการประมวลผล URL ของตัวเลข relatif

ตัวอย่าง หากเบราเซอร์จะโหลดเอกสารจาก URL https://www.codew3c.com/js/index.asp นี้ และเอกสารนี้มีลิงก์ที่ใช้ URL ของตัวเลข relatif คือ html_basic.asp นั้น ตอนที่กดลิงก์นี้เบราเซอร์จะพยายามโหลดเอกสารที่ URL ที่เป็นพื้นฐานเป็น URL ของตัวเลข absoluut คือ https://www.codew3c.com/js/html_basic.asp
