Time to take another look at directives and not only repeat quickly

0:06

S… Speaker 1 (93. Module Introduction)

what we learned thus far,

0:07

S… Speaker 1 (93. Module Introduction)

but also learn how to build our own directives and really

0:11

S… Speaker 1 (93. Module Introduction)

dive into the difference between attribute and structural directives and what this star

0:15

S… Speaker 1 (93. Module Introduction)

means on the structural directives.

0:17

S… Speaker 2 (93. Module Introduction)

Well,

0:18

S… Speaker 1 (93. Module Introduction)

I already said it,

0:19

S… Speaker 1 (93. Module Introduction)

right? We got attribute and structural directives.

0:22

S… Speaker 1 (93. Module Introduction)

Attribute directives are called like this because they sit

0:27

S… Speaker 1 (93. Module Introduction)

on elements just like attributes and structural directives

0:31

S… Speaker 1 (93. Module Introduction)

basically do the same,

0:32

S… Speaker 1 (93. Module Introduction)

but they also change the structure of the DOM around this element.

0:36

S… Speaker 1 (93. Module Introduction)

If you have ngf on a paragraph,

0:39

S… Speaker 1 (93. Module Introduction)

if that condition is false,

0:41

S… Speaker 1 (93. Module Introduction)

this paragraph is removed from the DOM,

0:44

S… Speaker 1 (93. Module Introduction)

so the overall view container is affected.

0:46

S… Speaker 1 (93. Module Introduction)

Whereas on the attribute directive,

0:48

S… Speaker 1 (93. Module Introduction)

you never destroy an element from the DOM,

0:51

S… Speaker 1 (93. Module Introduction)

you only change properties of that element,

0:54

S… Speaker 1 (93. Module Introduction)

for example,

0:54

S… Speaker 1 (93. Module Introduction)

the background color.

0:56

S… Speaker 1 (93. Module Introduction)

So that is why we have attribute directives only affecting the

1:00

S… Speaker 1 (93. Module Introduction)

element they sit on and structural directives,

1:02

S… Speaker 1 (93. Module Introduction)

which also affect the whole DOM or the view container,

1:05

S… Speaker 1 (93. Module Introduction)

the area around the element which they were placed on.

1:09

S… Speaker 1 (93. Module Introduction)

That is the difference.

1:10

S… Speaker 1 (93. Module Introduction)

Now with that,

1:11

S… Speaker 1 (93. Module Introduction)

let's briefly have a look at the directives we already know and how

1:15

S… Speaker 1 (93. Module Introduction)

to use them before we then dive into building our own ones and learn more about structural

1:20

S… Speaker 1 (93. Module Introduction)

directives.
