jQuery and AJAX Tutorials 14 | The Algorithm Design Video Lecture | AJAX and jQuery: Complete Series for Beginners - Front-End Programming

hey what's up guys my name is Elias and
welcome to your fourteenth jQuery
tutorial in this tutorial we are going
to continue programming our chat bar and
its algorithm so we already taught the
chat bot to ask for our name but the
chat bot still doesn't know what to do
with it so we are going to teach it yeah
let's enter our coding mode and the next
thing I would like to do I don't like
the way we display this this messages
right here so I want to create our own
function called function send message
which takes as a parameter a variable
name called message and what this
function should do the function should
access the jQuery by this dollar sign
and edit this container this container
this div container HTML contents so let
me just cut this one got this line of
code and paste it right here and instead
of typing this message here I will
delete it so and outside of the
parenthesis I will just say plus and
message so what this code will do if I
call the function send message using a
parameter as a text the this function
will access jQuery and the div container
with this ID and place this piece of
piece of code right here and add the
message which we passed to this function
so and in the function username we can
just call the function send message and
just type the text like say hello what
is your name yeah so make sure this code
works yeah it does so we didn't really
see anything on the screen but doesn't
matter and the next function I would
want to create I will just quote
ái which will stand for artificial
intelligence I don't know
and we can also pass a parameter to it
called message because this function
will get a message from the from the
form of the user input so and every time
we send the message we will also will
not only display the message of the
screen but also we will provide the
message we just type to the bot so the
bot knows what to do with that anyway
after displaying the message on the
screen we can call function AI and pass
this new message path is a new message
parameter right here and what new
message is well the new message is the
message huge you enter from the formula
keyboard and then you would press send
and the message will be displayed so
after the message is sent as I said the
message is also goes to this AI function
so the bot gets the message pretty much
and well inside of this AI function we
can create our first statement which is
if statement and we will check if the
user name is is provided so we can
create a variable called username and
Senate equal to 2 m t2 MTR I don't know
like just two parenthesis and if
username dot length is bigger than
greater than then 3 no is less than 3
that means the username is not provided
we can store it we can save it so we can
say username should be equal to message
and so
we stored the username into the bots
memory and then you can display a
message saying hello username how are
you doing or something so we can copy
the send message code line and say hello
or we can just say nice to meet you then
plus username then plus empty
parentheses not an empty parentheses
space no comma space how are you doing
yeah so let's just go ahead and test
this thing ah
something is wrong it says property
username of object object is not a
function umm
oh I'm sorry I shouldn't have created
the function and a variable with the
same name so we can rename the function
username to get user name which is
actually a better name for a function
since normally if you have a function
function use it would use a verb for a
function so yeah and now the code is
running without any errors hello and
what is your name my name is Elias and
it's it says nice to meet you Ilyas how
are you doing well this is the beginning
anyway and after the nice to meet you I
think we have to put a space so we are
not done with this functionality
unfortunately but the time is up so in
next tutorial we are going to improve
this feature so I hope you guys liked it
and I'll see you in the 15th tutorial
have a nice day
you
