Zokhutira, chitetezo ndi malingaliro apangidwe a ANTHU
The element ikulowetsani kuti mulowe masamba ena a Webusaiti mwa tsamba lanu. Koma pogwiritsira ntchito mafayilo pali zinthu zina zotetezeka ndi zosinthika zomwe sizinalembedwe mu HTML 4.01. HTML5 imabweretsa makhalidwe atatu atsopano pazinthu izi kuti zithetse mavuto awa:
Bokosi la mchenga
Bokosi la mchenga wa chigawo cha IFRAME ndiwothandiza kwambiri chitetezo cha mafayilo. Mukaziyika mu chinthu chophatikizapo IFRAME, mukuphunzitsa wothandizila kuti asakane zinthu zomwe zingayambitse chitetezo kwa tsamba ndi ogwiritsa ntchito.
Mwachitsanzo:
Amauza msakatuliyo kuti asalole zinthu zonse zomwe zingakhale chiopsezo cha chitetezo. Makamaka, mapulagini saloledwa. Mafomu sangathe kutumizidwa. Zolemba sizidzathamanga ndi kugwirizana kunja kwa IFRAME siziloledwa. Pomalizira, kupeza ma cookies, kusungirako kwanuko ndi masamba ena omwe ali nawo (chiyambi) saloledwa.
Ndiye, pogwiritsa ntchito mfundo zamtengo wapatali za sandbox, mukhoza kubwezeretsanso zina mwazochitikazo. Mawu awa ndi awa:
- kulola-mawonekedwe -lowetsani kujambulitsa
- lolani-chiyambi--lowetsani malemba kuti mupeze zokhudzana ndi ma cookies kuchokera kumalo omwe amachokera
- kulola-zikalata -letsani malemba kuti athandize mu IFRAME iyi
- kulola-pamwamba-kutsegula-kulemba ziphatikizo za IFRAME ndi zolemba ku cholinga cha _top
Sizifukwa zomveka kuyika zonse zovomerezeka ndi zolemba zomwe zimagwirizanitsa palimodzi. Ngati mutachita izi, pepala lothandizidwa likhoza kuchotsa mwatsatanetsatane malingaliro a bokosi la mchenga, kunyalanyaza phindu lililonse.
Chizindikiro cha srcdoc
Chidziwitso cha srcdoc ndi chidziwitso chomwe chimapatsa Webusaiti kuti azilamulira kwambiri mafayilo komanso chitetezo chochuluka. M'malo mogwirizanitsa ndi tsamba la webusaiti pa URL yosiyana, Web designer amaika HTML yomwe ikuwonetsera mu IFRAME mkati mwa chikhalidwe cha srcdoc.
Poyamba, mwina mukuganiza kuti, "Kodi izi zikusiyana motani ndi kuika HTML pomwepa?" Ndipo mwa njira zina, siziri zosiyana kwambiri.
Koma muyenera kukumbukira chimodzi mwa ntchito za IFRAME, zomwe ziyenera kusunga deta yopanda chilema kuchoka pa malo onsewa.
Mwa kuyika HTML yomwe imapangidwa ndi chitsime chosakhazikika, monga fomu, kukhala IFRAME mungathe "sandbox" zomwe mulibe zowonongeka ndipo mukuziwonetsanso patsamba. Ndemanga za blog ndi chitsanzo. Ambiri a blogs ali ndi chiwerengero chochepa cha malemba a HTML omwe olemba ndemanga angagwiritse ntchito ndemanga zawo. Koma poika ndemangazo mu sandboxed IFRAME pogwiritsa ntchito chidziwitso cha srcdoc, ndemanga zikhoza kukhala zamphamvu komabe zimateteza malo onsewo.
Security ndi Iframes
Zizindikiro ziwiri zapamwambazi zimapereka chitetezo kwa zinthu ZANU ZONSE, koma sizitsimikizirani pa malo onse oipa. Ngati tsamba loipa lingawonetse wogwiritsa ntchito kuti adziwe zowonongeka mwachindunji (monga kuyika URL mu msakatuli wawo) akhoza kuchitidwa.
Ngati n'kotheka ndibwino kuyika zomwe zili mu sandboxed IFRAME monga mtundu wa MIME / html-sandboxed.
Chikhumbo chopanda ntchito
Chidziwitso chosasunthika chiri chikhumbo cha chipolopolo chomwe chimauza osatsegula kuti afotokoze IFRAME ngati kuti ili gawo la zolemba za makolo. Ngati mukufuna kuti IFRAME yanu iwonetsedwe mosasunthika, ingosaninso zizindikiro izi muzigawo:
