S… Speaker 2 (187. Why do we Need Angular's Help)
So let's take a closer look at how Angular works together with forms.
0:06
S… Speaker 2 (187. Why do we Need Angular's Help)
Consider this form.
0:08
S… Speaker 2 (187. Why do we Need Angular's Help)
This is the HTML code of a form which you might use and
0:12
S… Speaker 2 (187. Why do we Need Angular's Help)
there is nothing Angular specific about this code.
0:15
S… Speaker 2 (187. Why do we Need Angular's Help)
It's normal HTML code which you would place in your HTML documents to
0:19
S… Speaker 2 (187. Why do we Need Angular's Help)
maybe display a form like this with an input for the username and
0:23
S… Speaker 2 (187. Why do we Need Angular's Help)
the input for the email address.
0:26
S… Speaker 2 (187. Why do we Need Angular's Help)
Now as mentioned in the last video,
0:27
S… Speaker 2 (187. Why do we Need Angular's Help)
Angular's job now is to allow you to retrieve the
0:32
S… Speaker 2 (187. Why do we Need Angular's Help)
values the user entered here and also to check some
0:36
S… Speaker 2 (187. Why do we Need Angular's Help)
other things like is the form valid,
0:38
S… Speaker 2 (187. Why do we Need Angular's Help)
did the user enter valid information.
0:41
S… Speaker 3 (187. Why do we Need Angular's Help)
And all that,
0:42
S… Speaker 2 (187. Why do we Need Angular's Help)
of course, will happen in JavaScript,
0:44
S… Speaker 2 (187. Why do we Need Angular's Help)
in TypeScript,
0:45
S… Speaker 2 (187. Why do we Need Angular's Help)
so on the Angular 2 side of your app,
0:48
S… Speaker 1 (187. Why do we Need Angular's Help)
you could say.
0:49
S… Speaker 2 (187. Why do we Need Angular's Help)
So you somehow need to be able to parse the values
0:53
S… Speaker 2 (187. Why do we Need Angular's Help)
the user enters,
0:54
S… Speaker 2 (187. Why do we Need Angular's Help)
and you somehow need some JavaScript object representation
0:58
S… Speaker 2 (187. Why do we Need Angular's Help)
of your form in your TypeScript code to work with.
1:03
S… Speaker 2 (187. Why do we Need Angular's Help)
So this object could look something like this.
1:06
S… Speaker 2 (187. Why do we Need Angular's Help)
It is more complex in reality,
1:08
S… Speaker 2 (187. Why do we Need Angular's Help)
but these would be the key features we need,
1:10
S… Speaker 1 (187. Why do we Need Angular's Help)
for example.
1:11
S… Speaker 2 (187. Why do we Need Angular's Help)
We need to have the value of the form.
1:14
S… Speaker 2 (187. Why do we Need Angular's Help)
And there it would be convenient if we would have key value pairs where the
1:18
S… Speaker 2 (187. Why do we Need Angular's Help)
key refers to the name of input,
1:21
S… Speaker 1 (187. Why do we Need Angular's Help)
like for example,
1:22
S… Speaker 2 (187. Why do we Need Angular's Help)
name or email as specified in the HTML code.
1:27
S… Speaker 2 (187. Why do we Need Angular's Help)
And then it holds the values the user entered.
1:30
S… Speaker 2 (187. Why do we Need Angular's Help)
This would make it super simple for you to work with these values in
1:34
S… Speaker 2 (187. Why do we Need Angular's Help)
your TypeScript code and to do something with the values the user entered.
1:38
S… Speaker 2 (187. Why do we Need Angular's Help)
It might also be helpful if some metadata was stored,
1:42
S… Speaker 1 (187. Why do we Need Angular's Help)
like for example,
1:43
S… Speaker 2 (187. Why do we Need Angular's Help)
if the form is valid.
1:44
S… Speaker 2 (187. Why do we Need Angular's Help)
And this would be changed to false,
1:47
S… Speaker 1 (187. Why do we Need Angular's Help)
for example,
1:48
S… Speaker 2 (187. Why do we Need Angular's Help)
if the email address wouldn't be a valid email address.
1:51
S… Speaker 2 (187. Why do we Need Angular's Help)
This is what Angular does for you.
1:54
S… Speaker 2 (187. Why do we Need Angular's Help)
It allows you or it gives you actually such a JavaScript
1:58
S… Speaker 2 (187. Why do we Need Angular's Help)
object representation of your form,
2:01
S… Speaker 2 (187. Why do we Need Angular's Help)
making it simple for you to retrieve user values and to
2:05
S… Speaker 2 (187. Why do we Need Angular's Help)
see the state of the form and work with it.
2:08
S… Speaker 1 (187. Why do we Need Angular's Help)
Now in the next lectures,
2:09
S… Speaker 2 (187. Why do we Need Angular's Help)
we're going to take a detailed look and we will understand how exactly
2:13
S… Speaker 2 (187. Why do we Need Angular's Help)
it works, how we can configure it,
2:15
S… Speaker 2 (187. Why do we Need Angular's Help)
what we can do with it,
2:16
S… Speaker 2 (187. Why do we Need Angular's Help)
how we can reset it and much more.
