There is no WiFi. My life is empty and meaningless. Time to go to the coffee shop! For me, that’s twenty minutes. For you, it’s the next character over -> Someone has my chair. I’m not happy about this. The light is all wrong, the pillows are weird, there’s only one armrest, I sound like Sheldon Cooper! haha! I’ll wait until they leave, and then strike!
HTML/CSS
Psuedo--class selectors; that's what I'm starting with today. Lesson people say: "A pseudo-class selector is a way of accessing HTML items that aren't part of the document tree (remember the tree structure we talked about earlier?). For instance, it's very easy to see where a link is in the tree. But where would you find information about whether a link had been clicked on or not? It isn't there!" Example: You know how when you click on something, it usually changes color like, blue to purple? That's what this is. And then there's the CSS thing where something changes when you hover over it:
a:hover {
color: #cc0000;
font-weight: bold;
text-decoration: none;
} So, now that we have that weapon in our arsenal, let's take it to the battlefield; the console.
Alright, so now we have something to go with. Here's an e.g:
<!DOCTYPE html>
<html>
<head>
<link type="text/css" rel="stylesheet" href="stylesheet.css"/>
<title></title>
</head>
<body>
<div>
<a href = "https://www.google.com/">Google</a>
<a href = "https://www.yahoo.com/">Yahoo</a>
<a href = "https://www.bing.com/">Bing</a>
</div>
</body>
</html>
This looks just like regular HTML that has some links to some search engines. But when the CSS comes in, we get something else:
a:link{
color:#008b45;
text-decoration:none;
}
a:hover{
color:#00ff00;
}
a:visited{
color:#ee9a00;
}
If you want to test this out, go here. Unless you don't use Chrome. In that case go here follow the instructions, and then click the first link and be amazed. And with that, I'll leave this segment, and head over to the next.
JavaScript
As I mentioned before, I found something interesting in my .js lessons. Yesterday, I was going over some lessons I'd already done. And realized something. I was looking at this code:
var bob = new Object();
bob.age = 30;
// this time we have added a method, setAge
bob.setAge = function (newAge){
bob.age = newAge;
};
bob.getYearOfBirth = function () {
return 2013 - bob.age;
};
console.log(bob.getYearOfBirth());
And I realized something. This section:
bob.setAge = function (newAge){
bob.age = newAge;
};
is completely unnecessary! I took it out, and the lesson still worked! I seriously don't think these peopele really knew what they were doing. Their newer classes look better, but I think this one should still be in beta. Once I got past that I went on to the rest of the lessons. I'm still on the constructors because they're taking their time teaching this, which I'm totally OK with since they are difficult to learn. Here's what they said about constructors: "Constructors are a way to make objects with the keyword <new>. The most basic constructor is the <Object> constructor, which will make an object with no methods or properties."
Ooooooh my. These people! Seriously shaking my head right now. I just passed my lesson using five different ways!! And most of them were just <undefined > or something similar. Which is just poop. There is no way that undefined is going to be ok in a real world situation. Here's the code:
function Rabbit(adjective) {
this.adjective = adjective;
this.describeMyself = function() {
console.log("I am a " + this.adjective + " rabbit");
};
}
var rabbit1 = new Rabbit("fluffy");
var rabbit2 = new Rabbit("happy");
var rabbit3 = new Rabbit("sleepy");
rabbit1.describeMyself();
At first, I tried to use <console.log> but apparently I was defining something wasn't there by using that, and then I tried a whole bunch of things, and they all passed, but I wasn't getting the return that I wanted. That's how I ended up with the code you see above. Kind of nifty. You just have to define a rabbit, and the words are already done. You don't have to write out each one, you just do it once! How neat!
Ok, this post is getting a little long here guys, so I'm going to call an end here. Remember to visit the links! Also, huzzah for beards.
