00:00:00,000 --> 00:00:00,220

00:00:00,220 --> 00:00:04,050
>> MWALIMU: Kwa hiyo, katika geolocation sifuri, mimi
alitangaza kazi mbili, mtu mmoja aitwaye

3
00:00:04,050 --> 00:00:08,070
geolocate ambayo geolocates user, na
mtu mmoja aitwaye wito nyuma ambayo ilikuwa

4
00:00:08,070 --> 00:00:11,730
kazi kwamba geolocate aitwaye
hatimaye kwa njia ya kupata sasa

5
00:00:11,730 --> 00:00:14,630
nafasi mara moja kisakuzi alikuwa figured
nje ambapo mtumiaji ni.

6
00:00:14,630 --> 00:00:18,400
Sasa, kutokana na kwamba mimi nina tu wito huu
kazi mara moja, na ipo tu kwa

7
00:00:18,400 --> 00:00:21,450
kuitwa kwa kupata nafasi ya sasa,
kitaalam, hakuna sababu ya kuwa mimi

8
00:00:21,450 --> 00:00:24,640
alikuwa na kutangaza kama kazi tofauti
na kuwapa jina lake mwenyewe.

9
00:00:24,640 --> 00:00:27,800
Badala yake, mimi nilikuwa na tu kutekelezwa
kazi bila majina,

10
00:00:27,800 --> 00:00:31,780
inayojulikana kama lambda kazi,
ufanisi kupita katika kificho kwamba mimi

11
00:00:31,780 --> 00:00:35,990
wanataka wauawe baada ya kupata sasa
nafasi kimepata user.

12
00:00:35,990 --> 00:00:38,730
>> Hasa, Ningependa
wamefanya zifuatazo.

13
00:00:38,730 --> 00:00:41,550
Kwanza, hebu kuonyesha na kukata hii
mstari wa kanuni hapa katika callback yangu

14
00:00:41,550 --> 00:00:43,240
kazi ili kuitumia baadaye.

15
00:00:43,240 --> 00:00:45,960
Lakini hebu kujikwamua callback
kazi zote kwa pamoja.

16
00:00:45,960 --> 00:00:49,780
Sasa, ndani ya geolocate kazi,
hebu kuonyesha na kufuta jina la

17
00:00:49,780 --> 00:00:53,190
kazi kwamba nilikuwa awali
wito, na badala yake, kutangaza

18
00:00:53,190 --> 00:00:56,090
bila majina kazi na hakuna
jina kwamba bado inachukua

19
00:00:56,090 --> 00:00:57,940
hoja aitwaye Position.

20
00:00:57,940 --> 00:01:01,240
Na kisha baada ya hayo, kwa mkataba,
hebu kuweka wazi curly brace.

21
00:01:01,240 --> 00:01:04,250
Chini hapa hebu kuweka kufunga curly
brace na kufunga mabano na

22
00:01:04,250 --> 00:01:05,170
semicolon.

23
00:01:05,170 --> 00:01:07,940
>> Na kisha ndani ya hii vinginevyo
kazi bila majina, hebu kuweka katika

24
00:01:07,940 --> 00:01:11,020
mstari wa kanuni kwamba tunatarajia bado
kama kuitwa.

25
00:01:11,020 --> 00:01:14,180
Hatimaye, kisha, kila nimepata kufanyika ni
kuchukua nafasi ya jina lake kazi pamoja na

26
00:01:14,180 --> 00:01:17,030
kazi bila majina lakini si iliyopita
ukurasa wa utendaji.

27
00:01:17,030 --> 00:01:20,260
Lakini hii ni arguably kidogo safi
kwa sababu mimi si yakizidi code yangu na

28
00:01:20,260 --> 00:01:22,230
usiokuwa na kuelezwa kazi.

29
00:01:22,230 --> 00:01:26,890
Badala yake, mimi nina tu kufafanua code mimi
wanataka wauawe hasa ambapo ni

30
00:01:26,890 --> 00:01:27,700
maana ya kuitwa.

31
00:01:27,700 --> 00:01:30,510
>> Hebu kuokoa faili na kufungua
ukurasa katika browser.

32
00:01:30,510 --> 00:01:39,330
http://localhost / geolocation1/html Na
huko mimi bado, katika Cambridge,

33
00:01:39,330 --> 00:01:41,130
Massachusetts.

34
00:01:41,130 --> 00:01:42,380
Anonymously.
