Welcome back, my friends, to another lecture we're going to learn about dumb and dumb manipulation.
So if you're not subscribe to some of my journals, please go there.
If you watched this from some course, then stay sane still.
Go on my YouTube channel, because I'm going to put some awesome videos there and subscribe to my channel
because you're going to get more content and out of, for example, out of the courses.
So you're going to get some extra materials.
So it's good to have you as a student, as a subscriber, as my family and friends.
Right now we're going to learn here about dumbed down manipulation, why it's so important.
Before we didn't do any manipulation.
We just use comes a lot.
We just print out things.
We didn't work with JavaScript, how JavaScript in a browser works.
So that is why we need to see about dumbed down manipulation.
So again, I have color coding the time I have dumbed down manipulation just so you can read it in what
is dumb.
Dumb defines a standard for accessing documents.
What is dumb dumb is the standard object model and programming interface for HDR.
So it defines how the system elements as objects, the properties of these elements, the methods,
the events in all of it.
In short terms, we use each team of Dom to get change, all delete.
So to do a lot of it seem like an application we are doing with BHP right now.
There is a dumb diagram here, link from Ian and you can go there, check it out.
Now there are nodes called in a Adam three nodes.
So I just want you to read carefully.
So we now reemphasise all the websites that we are building.
We will want to manipulate the document structure.
That's why we will use Dom.
So we want to manipulate the structure.
So behind these text is HTML structure, right?
That's what I'm trying to do.
These are tree like structure, so representation created by browser.
And here it is.
We have nodes inside.
Dom is represented with no.
So it's useful to know the terminology before working with them.
So there is a written code is actually start here and that's the top in the tree in the A.T.M. page.
It's called HTML Node.
Right, because we have XML pages, stuff like that, and there is a different naming for those.
But in the e-mail it's called Sometime we'll know you have element node and its element that exist inside
is down.
There's a top note, for example, in this, let's put it here.
So if we have the body in here, we have IMG that we have sections for it sort of here in inside this
section gallery, we do have energy and that is the child.
Another descending node.
Actually, this element or this or I don't know which element here is descending node of the body.
There was a parent node, sibling node techno.
So please check them out.
You don't I don't want you to bore you with too much information here because we're going to do a lot
of these things with our code and you will understand them.
So if it's not clear now, don't worry about it will be clear when we start working on our code.
Now, thanks for watching.
I hope you enjoy this one.
It was super short and now you know what Dom is.
So the is a standard object model and programming interface for HTML.
And Dom stands for Document Object Model, a set of apps for controlling H.M.S. styling information.
So I don't want to sit here and read all of this.
I can do that.
But that's not my thing.
If it's your thing, just please watch it, do it and put some put put some comment here.
It will make me feel better.
Right.
So thank you very much.
And please share subscribe like a five star review.
Whatever you watching this.
Wherever, whatever you can do, just do it because I will appreciate so much.
So thank you very much.
See you in the next one.
