the event | 3,900.86 | 2.85 |
so what received the event it was the | 3,901.73 | 3.72 |
select drop-down that is what received | 3,903.71 | 4.29 |
the event is being changed and so this | 3,905.45 | 4.8 |
is going to be a special keyword that | 3,908 | 4.17 |
always refers to that that always refers | 3,910.25 | 4.05 |
to the drop-down menu where I made a | 3,912.17 | 3.93 |
different selection so if I want to get | 3,914.3 | 3.54 |
the value of that drop-down menu what it | 3,916.1 | 4.14 |
is the user actually selected I can just | 3,917.84 | 5.04 |
say this dot value to mean get that | 3,920.24 | 4.74 |
drop-down menu and get at the value the | 3,922.88 | 3.81 |
thing that the user is selected in that | 3,924.98 | 4.08 |
idea and now much more succinctly than | 3,926.69 | 4.92 |
before I've been able to implement the | 3,929.06 | 4.56 |
same kind of idea says hello right now | 3,931.61 | 3.66 |
in black but if I choose from the | 3,933.62 | 3.48 |
drop-down menu to change its color to | 3,935.27 | 3.72 |
something like red for example color | 3,937.1 | 4.23 |
changes to red if I instead choose blue | 3,938.99 | 4.59 |
it changes to blue green changes to | 3,941.33 | 4.98 |
green I choose black it changes back to | 3,943.58 | 5.04 |
black so now I have this ability to | 3,946.31 | 4.11 |
detect these other types of events and | 3,948.62 | 4.05 |
respond to them as well and there are | 3,950.42 | 4.65 |
many many different events that exist in | 3,952.67 | 4.2 |
JavaScript there's on-click which we've | 3,955.07 | 4.2 |
seen already on mouse-over can detect | 3,956.87 | 3.84 |
like when you mouse over something when | 3,959.27 | 2.64 |
you're hovering over a particular | 3,960.71 | 2.97 |
element if you've ever seen web sites | 3,961.91 | 3.54 |
that somehow respond when your mouse | 3,963.68 | 3.57 |
moves over something that can be how | 3,965.45 | 4.29 |
it's implemented on key down and onkeyup | 3,967.25 | 4.23 |
can respond to keyboard event something | 3,969.74 | 4.32 |
like when you press a key on the | 3,971.48 | 4.14 |
keyboard when you press down on the key | 3,974.06 | 3.69 |
that's on key down and when you lift | 3,975.62 | 3.9 |
your finger off the key that's on key up | 3,977.75 | 4.14 |
and there are other events as well many | 3,979.52 | 3.78 |
more events that are just listed here | 3,981.89 | 3.93 |
that you can listen for and respond to | 3,983.3 | 4.38 |
so that you can really interact with the | 3,985.82 | 3.99 |
user based on what it is that they're | 3,987.68 | 4.23 |
doing so now let's take a look at an | 3,989.81 | 3.99 |
example of how we can use some of these | 3,991.91 | 3.96 |
events to now begin to create a little | 3,993.8 | 4.05 |
bit of a more interesting application | 3,995.87 | 4.23 |
we'll go ahead and build a to-do list | 3,997.85 | 4.1 |
application this time using exclusively | 4,000.1 | 3.78 |
JavaScript we've seen to-do lists before | 4,001.95 | 3.91 |
that involve communicating with a server | 4,003.88 | 3.99 |
making requests and responses will now | 4,005.86 | 4.08 |
build it to-do list that only uses | 4,007.87 | 4.53 |
JavaScript to do so so I'll create a new | 4,009.94 | 7.65 |
file called tasks HTML and we'll use a | 4,012.4 | 7.5 |
we'll create a head section whose title | 4,017.59 | 5.67 |
is tasks and a body section and inside | 4,019.9 | 5.1 |
the body of the page I'll go ahead and | 4,023.26 | 2.79 |
have a heading that says | 4,025 | 4.08 |
tasks and underneath that I want an | 4,026.05 | 5.46 |
unordered list of all of my tasks so | 4,029.08 | 4.05 |
I'll have an unordered list I'll give it | 4,031.51 | 3.9 |
an ID of tasks just for good measure so | 4,033.13 | 4.05 |
I can reference it later but initially | 4,035.41 | 4.32 |
nothing's going to be in here but what | 4,037.18 | 4.08 |
I'll have underneath the unordered list | 4,039.73 | 4.92 |
is a form a form where I can submit a | 4,041.26 | 5.52 |
new task for example so I'll give myself | 4,044.65 | 4.74 |
an input field also given an ID the ID | 4,046.78 | 4.83 |
will be tasks singular for the new task | 4,049.39 | 5.43 |
that I am typing in the placeholder will | 4,051.61 | 5.1 |
be new tasks just so the user knows what | 4,054.82 | 3.78 |
to type in and the type of the input | 4,056.71 | 3.78 |
field will be text so I have an input | 4,058.6 | 3.54 |
field where the user can type in some | 4,060.49 | 3.84 |
new tasks and I'll also add an input | 4,062.14 | 3.93 |
field for good measure whose type is | 4,064.33 | 3.93 |
submit that allows the user to submit a | 4,066.07 | 4.83 |
new task once they've created it so if I | 4,068.26 | 6.09 |
open up tasks dot HTML here's then what | 4,070.9 | 5.67 |
I see big heading there is technically | 4,074.35 | 4.23 |
an unordered list underneath it here but | 4,076.57 | 3.69 |
there's nothing in that unordered list | 4,078.58 | 3.72 |
yet so it just shows up as empty then a | 4,080.26 | 3.39 |
text field where I can type in a task | 4,082.3 | 3.54 |
and then a submit button where I can | 4,083.65 | 5.85 |
submit my new task so now I'd like some | 4,085.84 | 5.25 |
JavaScript such that when I submit this | 4,089.5 | 4.53 |
form we actually do something so add a | 4,091.09 | 3.69 |
script tag | 4,094.03 | 5.37 |
I want this JavaScript to run after the | 4,094.78 | 8.94 |
Dom content is loaded so we'll go ahead | 4,099.4 | 5.85 |
and add the usual Dom content loaded | 4,103.72 | 4.65 |
event listener and now I want to run | 4,105.25 | 5.91 |
code when the form is submitted so I can | 4,108.37 | 7.949 |
say document query selector form dot on | 4,111.16 | 7.77 |
submit equals and then I want to run a | 4,116.319 | 4.29 |
function and I could use the keyword | 4,118.93 | 2.88 |
function again but I can just use an | 4,120.609 | 2.371 |
