Hello and welcome.
Thank you so much for your time today.
In this lecture on Ajax you will learn what Ajax is.
You learn the difference between TTP and hate.
TTP Yes.
You learn what an egg smell his T T P request object is.
You'll learn how Ajax works.
So I'll show you a basic illustration of how Ajax works.
So what is Ajax.
Ajax stands for synchronize javascript and SML Ajax allows you to date parts of a web page without reloading
the entire page.
So we do jacks.
You can update certain parts of your web page without reloading the web page.
The ability to make changes without reloading the web page is what is known as a synchronoss behaviour.
So we pay jacks.
You can exchange small amounts of data with a server behind the scene and make it seem less thus possible
so all these is synchronous behaviour.
Ajax allows changes to go on without reloading.
An example of Ajax is the Google Google Suggest home page.
So for example you are trying to type in a search Ajax For example let's see and try a typing chocolate.
I go see all shop.
All you see is me.
Various suggestions here.
This is done using AJAX So as I am typing it sends a message to the server.
This server cons about and gives me a suggested list of items and printer type.
He does all these without reloading the web.
What is the difference between.
Hey TTP and hey.
T T P S hasted did P sounds for hypertext transfer protocol.
It is a method of transporting information online between web browsers so they hated t.p without the
s is not secured while the his T T P with the case is secure.
So wherever you see his T T P S that that identifies at if he's a secured connection happen between
two browsers.
So the information that is transporter using the TTP S is usually encrypted and secure information.
This is a basic illustration of how the TTP and his TTP put to call works.
So if you're a user here on your Web browser you can transport information via the hey TTP and the information
will not be secured.
So this is normally where you trance where you transferring information via these TTP.
You using the port 80 which is a normal TTP port is an insecure connectionist not secure.
However if you are using an encryption and use it you be using the TTP s.
The S in his TTP makes the connection secure.
Usually with a Hitty t p s it uses a secure connection or four for three and a date.
You can see the blue bit there the data transported is encrypted that is secured using the ss s s l
l certificate the s s l l certificate r what they are.
There are small piece of data files that digit lead binds a cryptographic key to unorganized ancient
details.
So when when it is installed on a web server it activates the padlock and the hated t p s to call transpose
the data over the port 443.
This allows the data to go through a secure unprotected connection.
Forth between web browsers or any data transported using the T T P S is secured and is usually transported
via a port.
Number 4 4 3.
What is and what is ex email.
T P T P requests objet.
This is very important.
Cause this object is what Ajax uses to exchange data with this server behind the scene so all the action
that is perform using AJAX is done behind the scene.
He is in the SML.
T T P request object.
All modern web browsers have a built teen ex email on his t t p requests object.
It is used to exchange data with a web server behind the scene.
This allows the web browser to date parts of a web page without reloading the whole page so the BE behaviour
whereby Ajax is able to obfuscate parts of a web page without reloading.
Web page is known as a synchronoss and he does this using the XM mail.
Hey TTP request object.
So this is an illustration of how Ajax works.
For example you got your web browser here.
When an event occurs in a Web browser for example when you click on the button what happens it creates
an exit mail his TTP request object saw was the object is created.
It then sends a request over the Internet to the web server.
So what happens to web server process this the Hayes TTP request he creates his response and sends the
respond back over the Internet to the web browser.
So what happens.
The response that comes back from the server is processed.
The data is processed using JavaScript and there was javascript processors.
The data headend of dates.
The web page.
Okay so this is how jazz works first.
For me it creates an XM old 80 to be a request object says a request over the Internet to the server.
This process this the TTP request a den creates a response to that request and sends data back to the
server over the Internet so did the data have now sent back and the process data is then transformed
the process interpreted using javascript.
So my script now works with the data that is passed back from the server of days to a web page and then
you see where change is done behind the scenes.
So jabaar Script is key here because it is what is used to process the data that is returned from the
server.
In this lecture up we learnt what a jackass this also learned about hate TTP and his TTP.
Yes.
Well let the differences between the two brutal called arsaell were lent a babik SML his TTP request
object which is what a jackass uses to pass on information to the server.
We saw saw an illustration of how Ajax works.
Thank you for your time.
Please let me know if he's got any questions.
I'll be more than delighted to help.
Or the best wishes and bye for now.
