S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

In the last lecture we had a look at the basic ngif syntax and

0:06

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

that's the syntax you're going to use most of the time.

0:08

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

There is one alternative to it though.

0:11

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Sometimes you have not only the if condition but also

0:15

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

an else condition.

0:16

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So here we might want to say server was created server name is

0:20

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

something with ngif but we could also add an else block

0:24

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

where we then want to say no server was created.

0:27

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Now, we deleted that exact text for the reason that we don't want to see it,

0:31

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

but imagine that we do want to show that alternative.

0:34

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So, no server was created,

0:37

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

could be the text here,

0:38

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

and now we want to show this paragraph only if ngif is not true,

0:42

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

or this condition,

0:43

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

server created,

0:44

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

is not true.

0:46

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

We can achieve this by placing a local reference

0:50

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

on this element here.

0:52

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And local reference is something I will dive deeper into in

0:57

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

the understanding components and data binding section of this course.

1:00

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

For now,

1:00

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

let's think of it as a marker.

1:02

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So I will name this no server,

1:05

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

any name you like.

1:07

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Let's name this no server with a capital S.

1:09

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And now we need to change the paragraph here to

1:14

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

ng -template.

1:15

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

That is a component,

1:17

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

a directive shipping with Angular,

1:19

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

which you can use to mark places in the DOM.

1:23

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And now I will add the paragraph back in this template with

1:28

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

the text in between like this.

1:29

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So now basically the text you want to output.

1:32

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And now with ng -template with the local references marker on

1:36

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

it, we mark a certain spot in the template,

1:39

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

which we want to show conditionally.

1:42

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Now to show it conditionally,

1:44

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

we simply enhance ngif by also adding else and

1:48

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

then no server.

1:50

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So this marker replaced on ng -template.

1:52

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And that's all the syntax we need.

1:55

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

If we save this,

1:56

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

you see no server was created.

1:58

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And as soon as I click here,

2:00

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

that gets replaced with server was created.

2:02

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

So that is ngif else.

2:04

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

A nice little addition in a use case where you have,

2:07

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

well, an else condition.

2:10

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Of course, the alternative would always be to simply use ngif with

2:14

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

the reversed check,

2:15

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

so with exclamation mark server created.

2:18

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

But that here is another nice alternative.

2:21

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Now,

2:21

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

I'm going to delete it.

2:23

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

You will find an article after the section here,

2:26

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

though, where you can find this code again in case you're interested.

2:29

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

And we will also use this code in the course project we're going

2:34

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

to build.

2:34

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

I just wanted to highlight that this option exists.

2:38

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Using NGF like this,

2:39

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

however, is the case you will see most often.

2:42

S… Speaker 1 (39_enhancing_nglf_with_an_else_condition)

Now let's continue.
