Paglilinaw at paggamit

formmethod Attribute na naghahatol ng HTTP na paraan na gagamitin sa pagpapadala ng form data.

formmethod Attribute na napagtagumpayan ang Attribute na method.

Babala:formmethod ang attribute ay pwedeng gamitin kasama type="submit" at type="image" magkasama

Ang form data ay pwedeng ipasalamin bilang URL variable (method="get") o bilang HTTP post na transaksyon (method="post")

Mga babala tungkol sa "get" na paraan:

  • Ito ay magdagdag ng form data sa URL bilang formang parang-paraan/nilalaman
  • Ito ay napaka-mahalaga para sa mga sumite ng form na nais na mag-save ng mga resulta bilang bookmark
  • Ang dami ng data na pwedeng ilagay sa URL ay limitado（kaugnay ng browser），kaya hindi maaring tiyakin na ang lahat ng form data ay maaaring ma-transmit ng maayos.
  • Huwag kailanman gamitin ang "get" na paraan para ipasa mabigat na impormasyon！（Ang password o ibang mabigat na impormasyon ay magiging nakikita sa address bar ng browser）

Mga babala tungkol sa "post" na paraan:

  • Ito ay nagpapadala ng form data bilang HTTP POST na transaksyon
  • Ang form na isinumite gamit ang "post" na paraan ay hindi maaaring i-save bilang bookmark
  • Kumpara sa "get" na paraan, ang "post" na paraan ay mas matibay at ligtas
  • Wala itong limitasyon sa laki

Halimbawa

Ang ikalawang sumite na pindutan ay napagtagumpayan ang HTTP na paraan ng form:

<form action="/action_page.php" method="get">
  <label for="fname">Pangalan：</label>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">Surnombre：</label>
  <input type="text" id="lname" name="lname"><br><br>
  <input type="submit" value="ส่ง">
  <input type="submit" formmethod="post" value="ส่งด้วย POST">
</form>
