arrow function which would be a little
4,121.81
2.52
bit faster to type just say alright
4,122.98
3.39
here's the function that I want to run
4,124.33
4.56
when the form is submitted and what
4,126.37
4.44
would I like to do well I'd first like
4,128.89
3.33
to figure out alright what did the user
4,130.81
3.84
actually type in and what the user typed
4,132.22
4.59
in well that'll be document query
4,134.65
7.8
selector task dot value get me the
4,136.81
7.17
element with ID task that's the input
4,142.45
4.2
field dot value gets the value of the
4,143.98
3.99
input field which is what the user
4,146.65
4.439
actually typed in and I can save that as
4,147.97
6.96
like Const tasks that is what it is the
4,151.089
6.96
user typed in and if I'm curious as to
4,154.93
4.56
what the user typed in I can
4,158.049
3.991
actually print it out to the JavaScript
4,159.49
4.32
console and the way to do that is using
4,162.04
4.11
a special function called console.log
4,163.81
4.65
and that just logs something to the
4,166.15
3.63
console the equivalent of printing
4,168.46
2.7
something out in Python where just shows
4,169.78
3.24
up in the Python terminal here this is
4,171.16
3.42
going to show up in the JavaScript
4,173.02
4.11
console and one other thing I'll add is
4,174.58
4.89
by default forms will try and submit
4,177.13
3.57
when you press the submit button like
4,179.47
2.97
take you to another page we've seen this
4,180.7
3.45
before already in the context of Django
4,182.44
3.57
that when you submit a form it tries and
4,184.15
3.93
submits another web request if I want to
4,186.01
3.81
prevent that behavior stop the form from
4,188.08
3.69
submitting it's a stop form from
4,189.82
6.81
submitting I can return false at the end
4,191.77
6.78
of my form submission handler to say
4,196.63
3.66
don't actually submit the form we're
4,198.55
3.03
gonna do everything client-side
4,200.29
3.75
everything just inside of the browser so
4,201.58
3.93
now this won't quite work yet but it'll
4,204.04
3.6
be progress i refresh the page I'm gonna
4,205.51
3.63
open up the JavaScript console so I can
4,207.64
3.42
see what's going on if I add a task
4,209.14
4.52
something just like foo press submit
4,211.06
5.76
this now gets logged to the JavaScript
4,213.66
4.63
console it's the equivalent of a way of
4,216.82
3.18
like providing debugging information to
4,218.29
2.97
myself to know all right
4,220
3.96
I now have access to this value foo and
4,221.26
4.41
it's also telling me what line of code
4,223.96
4.77
logged it it was tasks HTML line 9 is
4,225.67
5.52
the line of code that logged foo and so
4,228.73
3.6
this can be useful when you're debugging
4,231.19
2.73
a program when you want to see what the
4,232.33
3.51
values of variables are you can just
4,233.92
4.23
print them out using console log to
4,235.84
3.45
figure out what's going on in your
4,238.15
3.71
program and any particular point in time
4,239.29
5.1
but what I want to do is not console dot
4,241.86
4.39
log n what I want to do is really create
4,244.39
4.86
a new element that I'm going to add into
4,246.25
6.06
my body of the HTML so how can I do that
4,249.25
5.07
well to create a new element for my
4,252.31
3.9
document I can run a function called
4,254.32
5.4
document dot create element followed by
4,256.21
5.34
what type of element do I want to create
4,259.72
4.68
well I have an unordered list a ul and
4,261.55
5.01
every item inside of an unordered list
4,264.4
5.25
is a list item in Li so I'll go ahead
4,266.56
6.59
and create an Li element a list item and
4,269.65
6.48
I'll save that in a variable that I'll
4,273.15
6.34
call Li so I've created a new list item
4,276.13
7.44
and this list items inner HTML the HTML
4,279.49
6.81
content inside of that list item well
4,283.57
5.04
that's just going to be tasks this
4,286.3
4.26
variable from up here which is whatever
4,288.61
4.65
the user typed in so I've now created
4,290.56
5.52
newest item and said what GML should go
4,293.26
4.35
inside of the list item it should be
4,296.08
4.35
whatever task the user typed in and now
4,297.61
5.91
I'm going to say document dot query
4,300.43
6.03
selector tasks get me the element whose
4,303.52
5.04
ideas tasks and that's gonna be this
4,306.46
4.05
unordered list here the unordered list
4,308.56
4.86
whose ideas tasks and if I have an HTML
4,310.51
5.58
element I can add a new element inside
4,313.42
7.86
of it by saying dot append Li and with
4,316.09
7.02
that now is going to do is it's going to
4,321.28
3.48
say get me the unordered list whose
4,323.11
3.39
ideas tasks get me the element whose
4,324.76
3.63
ideas tasks by a query selector here
4,326.5
4.71
once I have that element append to the
4,328.39
4.49
end of what's inside of that element
4,331.21
5.13
this value Li which happens to be this
4,332.88
5.56
new element that I've created a new list
4,336.34
4.5
item so I've been able to add a new HTML
4,338.44
4.35
element and this line of code is going
4,340.84
4.11
to say add it to the Dom add it to the
4,342.79
3.9
unordered list that I am here now
4,344.95
7.77
constructing so now I rerun this I see
4,346.69
7.71
tasks I type in something like foo I
4,352.72
