Mastering Ember Js - 12 Ember Getters and setters Video Lecture | Build Web Applications: Ember.js - Web Development

hello everyone this is lamb in sunny of
cod Logica and in this tutorial video we
are going to have new look at ember
getters and setters so up until now
we've been having items in our
properties in our controller and we've
been displaying them in our template but
we haven't had a look at how to set
properties and get them inside of our
controller methods so let's just try to
see how that works so right now we have
the first name and last name in our
index controller called Jonny for first
name and Deb for last name so we'll
display that in our template I know
let's just say if you remember from
previous videos all you have to do is
first name last name okay so in our
browser when the refresh was to see
Johnny Depp displayed okay so that's
Johnny Depp all right but how do we set
internal controller to change these
values so we'll create a link method
here with an action of I would put
inside v ty so it's always online and
you won't have an H right but it will
have an action and the action will be
what we have in the controller here
which is called show alert so when we
click on the button we want to call that
action show alert and what that action
does is it's going to just show inside
our alert box these one JavaScript stuff
this is nothing but a later just pure
JavaScript and it's going to show the
actor is and we'll do that so now this
brings us to a question how do we get
inside this controller first name last
name any template we just buy into that
and template knows that we knows what to
do so how do we get them here
and in ember if you want to get
properties from a controller inside a
method all you have to do is just use
the get method in my soul test when you
said this is refers to the controller
instance in turn any method in the
controller or function whatever you want
to call it is all the same so this don't
get you might be used to in JavaScript
saying or you might have been tempted to
do something like first name to start
first name but that wouldn't work
because of how my bindings work and
there's a lot of stuff going on in the
background anytime you want to get a
property you must be against unless it's
been injected by a container or
something which we'll get to in another
video but if not this is how you get
properly so get the first name you do
start to get first name again
likewise for the last name so we do this
starts so now when we click on that link
let's refresh the browser first forgot
to put text inside the link let's say so
actor
yeah that should work so back in our
browser refresh my click this was to see
and others in Johnny Depp so the actor
is Johnny Depp that's fine
so one more thing for wrap up this
lesson how do we set properties them
you've been probably guessing we could
just use the set matter so let me say
set another actor just click another
action yeah that says they start set
first name when we say Michael so that's
for the first name and the last name
Schofield oh pumps spelling Schofield
right staff - from prison bike if you're
a big fan of it been watching it for a
while so we've set the first name last
name - Michael Scofield so let's just
alert that again just just show that
it's in change we save our new actor
equality
they start cat first name plus they
start gett last name okay so new actor
so we say the new actor is new actor
concatenate that in the alert box so now
let's create another link um just say
showing you actor and we say what's the
metal name let's just get out here go to
the second order actor so they click on
the second one is you just set a new
actor to Michael Scofield and then other
that so that's our first test now
clicking on show new actor show source
Michael Scofield
so click says the new actor is Michael
Scofield
so in ember that is how you get and set
properties and the same works for when
you're inside the boot as well or router
and yeah that's about it anymore
so she says that so next time you want
to get a property or set it don't do
something like this
dot last name because just know how my
works so probably in the future that
will change but as of now that's how it
is so that's it guys thanks for watching
