>> DAVID Malan: Kif dwar
web page ma 'immaġni?

2
00:00:02,150 --> 00:00:05,560
Ejja nassumu li, bil-quddiem, stajt
diġà jitniżżel JPEG ta 'immaġni

3
00:00:05,560 --> 00:00:07,290
mill-internet, jgħidu, qattus.

4
00:00:07,290 --> 00:00:08,650
L-internet huwa mimli magħhom.

5
00:00:08,650 --> 00:00:10,710
U stajt tpoġġi dan in
f'direttorju pubbliku tiegħi.

6
00:00:10,710 --> 00:00:13,030
F'dan l-istess f'direttorju pubbliku,
ejja toħloq paġna imsejjaħ

7
00:00:13,030 --> 00:00:15,630
image.html kif ġej.

8
00:00:15,630 --> 00:00:18,390
>> Stajt diġà gotten l-affarijiet bdew hawn
fil gedit ma 'xi tags miftuħa u

9
00:00:18,390 --> 00:00:19,540
xi tags qrib.

10
00:00:19,540 --> 00:00:23,330
Ġewwa tal-ġisem allura ta 'din il-paġna,
Ejja nagħmlu parentesi miftuħa, image -

11
00:00:23,330 --> 00:00:25,640
biss img, għalkemm, mhux il-kelma sħiħa -

12
00:00:25,640 --> 00:00:27,940
alt ispazju ugwali.

13
00:00:27,940 --> 00:00:31,400
alt tippermetti lili biex jipprovdu test alternattiv
għal din id-dehra, biss f'każ li l-

14
00:00:31,400 --> 00:00:34,360
utent ma jistax attwalment ara l-immaġni
Jien wasalt biex jipprovdu.

15
00:00:34,360 --> 00:00:38,930
Mela ejja sempliċiment jiddeskrivi dan
image bħala Cat Grumpy.

16
00:00:38,930 --> 00:00:42,490
U issa ejja jispeċifikaw li l-
sors ta 'din id-dehra, src -

17
00:00:42,490 --> 00:00:46,070
Għalhekk għal darb'oħra, mhux l-sħiħ
kelma, biss src -

18
00:00:46,070 --> 00:00:50,800
ugwali kwotazzjoni, unquote, "cat.jpg",
li għal darb'oħra, huwa l-fajl jsir

19
00:00:50,800 --> 00:00:54,220
qabel I jitniżżel fis
dan id-direttorju pubbliku.

20
00:00:54,220 --> 00:00:58,860
>> Ejja issa jingħalqu l-kwotazzjonijiet u
qrib l-tikketta kif ġej.

21
00:00:58,860 --> 00:01:02,650
Ikkunsidra li għal immaġni, hemm
verament ebda idea ta 'bidu ta' immaġni

22
00:01:02,650 --> 00:01:03,710
u l-waqfien ta 'immaġni.

23
00:01:03,710 --> 00:01:05,560
Huwa jew hemm, jew mhuwiex.

24
00:01:05,560 --> 00:01:09,715
Għalhekk ikun tħoss ftit stramba li
attwalment ikollhom tikketta qrib espliċita jew

25
00:01:09,715 --> 00:01:11,250
tag tmiem għal din tag immaġini.

26
00:01:11,250 --> 00:01:15,650
Allura HTML jippermetti li tinfetaħ u tingħalaq
l-tikketta fl-istess ħin, sempliċiment billi

27
00:01:15,650 --> 00:01:19,870
inkluża dik quddiem mmejla fl-
ħafna aħħar tal-lametta bidu, xorta

28
00:01:19,870 --> 00:01:21,880
ġewwa tal-parentesi angolata.

29
00:01:21,880 --> 00:01:24,790
>> Ejja issa jiffranka dan il-fajl, il-bidla
permessi tagħha, u għan

30
00:01:24,790 --> 00:01:28,130
ġewwa ta 'browser -

31
00:01:28,130 --> 00:01:32,460
chmod a + image.html r.

32
00:01:32,460 --> 00:01:42,090
Ejja issa jiftħu Chrome u żjara
http://localhost/image.html.

33
00:01:42,090 --> 00:01:43,630
A imkisser image icon -

34
00:01:43,630 --> 00:01:45,020
issa, għaliex jista 'jkun?

35
00:01:45,020 --> 00:01:48,330
>> Well, ejja tagħti ħarsa lejn il-kmand
linja lejn jekk I tabilħaqq tpoġġi dan

36
00:01:48,330 --> 00:01:50,750
fajl fil-direttorju pubbliku.

37
00:01:50,750 --> 00:01:55,960
Ejja ħa mmorru lura għall gedit, fil-
tieqa terminal, u jagħmlu ls-l.

38
00:01:55,960 --> 00:01:57,110
U hemm cat.jpg.

39
00:01:57,110 --> 00:01:58,790
>> Iżda tħares lejn l-permessi tal-fajl.

40
00:01:58,790 --> 00:02:02,410
Jidher li jkun il-każ li biss I,
is-sid, tista 'taqra u tikteb din

41
00:02:02,410 --> 00:02:03,460
JPEG fil-mument.

42
00:02:03,460 --> 00:02:05,810
Għandna bżonn bl-istess mod tagħti permessi
għad-dinja kollha biex

43
00:02:05,810 --> 00:02:07,350
dan JPEG jum ukoll.

44
00:02:07,350 --> 00:02:08,259
>> Mhux problema -

45
00:02:08,259 --> 00:02:12,460
chmod a + cat.jpg r.

46
00:02:12,460 --> 00:02:15,820
Ejja jikkonfermaw li dan huwa korrett
ma 'Ls-l-ieħor.

47
00:02:15,820 --> 00:02:21,350
U fil-fatt issa, kemm cat.jpg u
image.html qrajt permessi għall-

48
00:02:21,350 --> 00:02:22,310
id-dinja kollha.

49
00:02:22,310 --> 00:02:24,010
>> Ejja issa jmorru lura għall-browser.

50
00:02:24,010 --> 00:02:28,560
Ejja ikklikkja rikarigu jew Control-R. U
hemm, tabilħaqq, qattus dirtbag.
