1 00:00:00,600 --> 00:00:02,060 Hello and welcome. 2 00:00:02,250 --> 00:00:16,260 In this lecture we will be creating a mixed SML hate TTP requests are the SML H T T P request objet 3 00:00:16,860 --> 00:00:23,790 is the tool that does the heavy lifting in Ajax. 4 00:00:24,180 --> 00:00:28,400 All modern web browsers support the XM mail. 5 00:00:28,440 --> 00:00:37,620 He's TTP request objet and be sure to Hall have this built in to the web browser. 6 00:00:37,830 --> 00:00:49,160 So the ex email hated ATP request objet is used to exchange data with a web server behind the scenes. 7 00:00:49,500 --> 00:00:55,890 So all the stuff that it just does being the scene he does it using the XM mail. 8 00:00:56,010 --> 00:00:58,880 His TTP request object. 9 00:00:59,070 --> 00:01:09,240 So an ex email TTP request object has to be created first before that request he sent to the Web browser 10 00:01:09,660 --> 00:01:18,000 the web browser then creates a response for that request and sent it back to the web browser and then 11 00:01:18,000 --> 00:01:25,980 the web browser then performs an update using the data that has been sent back by the server. 12 00:01:26,220 --> 00:01:36,350 So XM mail hate TTP request object is used to exchange data with a web server behind the scene. 13 00:01:36,360 --> 00:01:45,680 This is what makes the web page of date without reloading the entire web page. 14 00:01:45,900 --> 00:01:55,800 So with this dp request objet it is possible to update parts of a web page without reloading entire 15 00:01:55,800 --> 00:01:57,070 web page. 16 00:01:57,120 --> 00:02:03,080 So let's create an ex email his TTP request. 17 00:02:03,090 --> 00:02:13,450 This is kind of like this syntax you would use to create one before a request can be sent to a web server. 18 00:02:13,800 --> 00:02:18,380 You must create an SML hasty Tippie request. 19 00:02:18,570 --> 00:02:21,140 So this is how you would create it. 20 00:02:21,150 --> 00:02:23,220 You begin with the word far. 21 00:02:23,280 --> 00:02:27,040 This is a variable and then you give the variable name. 22 00:02:27,150 --> 00:02:28,660 I've just given a Jane. 23 00:02:28,740 --> 00:02:31,530 Here you can give me any name you like. 24 00:02:31,720 --> 00:02:33,070 Doesn't really matter. 25 00:02:33,210 --> 00:02:35,150 And then this will be the value. 26 00:02:35,370 --> 00:02:37,350 This equals to here means value. 27 00:02:37,590 --> 00:02:41,430 So the value of the variable would be new. 28 00:02:41,430 --> 00:02:47,250 This news important which refers to a new exim Mail request. 29 00:02:47,250 --> 00:02:51,360 So this is the request that will be sent to the web server. 30 00:02:51,720 --> 00:02:57,870 So regardless of how many requests you make you have to create a new one each time. 31 00:02:57,990 --> 00:03:09,300 So if I want to term different parts data from a web page I will be creating various SML TTP request 32 00:03:09,660 --> 00:03:12,530 for each of the request I want. 33 00:03:12,690 --> 00:03:24,710 Okay so this is a syntax or how you would create an Excel mail he's TTP request object we roadsign here. 34 00:03:24,720 --> 00:03:28,240 This is standard for function in javascript. 35 00:03:28,290 --> 00:03:36,150 This is the variable and it was to hear signals the value of the variable in this led chart. 36 00:03:36,180 --> 00:03:48,440 We learned how to create a Excel TTP request objet using the syntax variable and they give the variable 37 00:03:48,470 --> 00:03:53,160 name and then give you the value the value will be new. 38 00:03:53,230 --> 00:03:54,020 X a male. 39 00:03:54,030 --> 00:04:00,600 His TTP request XM allocated to appear a request object is very important. 40 00:04:00,600 --> 00:04:05,280 It is used to exchange data with a web server behind the scene. 41 00:04:05,550 --> 00:04:14,370 So all the update that happens on the web server behind the scene without the website reloading is done 42 00:04:14,400 --> 00:04:16,110 using the SML. 43 00:04:16,150 --> 00:04:23,190 He t t p request subject without a smell his TTP of course object created. 44 00:04:23,280 --> 00:04:27,600 You can not send the request to the web server. 45 00:04:29,400 --> 00:04:38,880 So all request you've been making to the web so far will require you right in this syntax here. 46 00:04:38,880 --> 00:04:45,340 Variable then give a variable name and then it goes to New TTP requests. 47 00:04:45,420 --> 00:04:47,180 Thank you so much for your time. 48 00:04:47,220 --> 00:04:50,930 I hope the information has been useful. 49 00:04:51,010 --> 00:04:51,920 XO mail. 50 00:04:52,070 --> 00:04:59,920 To be request object also referred to as x h r the X is SML. 51 00:05:00,170 --> 00:05:04,140 Hate is hate is happy and in heartfully requests for short. 52 00:05:04,400 --> 00:05:14,280 So if you see x h ha they also mean X airmailed he's TTP request subject is just a shorter way to write 53 00:05:14,280 --> 00:05:15,050 it. 54 00:05:15,050 --> 00:05:15,980 Take care. 55 00:05:15,980 --> 00:05:17,460 Bye for now.
