This is a toggle that turns on or off a class based on a variable.
The other day I came across some code that helped me out with a problem I was having. It would add a class to an element, but with a different name. I was getting an error that said the class name wasn’t defined. I tried to add the class to the class, but it didn’t work. Then I tried to use the function I wanted it to be called with. It still didn’t work.
So I tried this out with a simple html select. When I checked the name, I was able to see that it wasnt defined. So I decided to make it an array.
Basically, the html select has to be an array, and the function that is being called has to be an array too. I added the array to the function, and the class was now defined, but the function wasnt. This is the problem the code is trying to solve. I was able to see the class, but the function wasn’t being called because it wasnt an array.
So we have a jQuery object that we’re trying to create. We’re using the. and # operators to create our selector. They’re so common that they’re pretty much just a convention. They dont have to be there. You can name them whatever you like, but I prefer #, because it starts with 0.
jQuery (or any selectors) are really a really simple way to create a selector.
Theyre also a way to create a selector as if you had to write a lot of code, but you can just write selectors by hand. And because you can just define them as variables, you can create a selector without having to write a line of code. So instead of writing selectors like we did in our example, we can just create the selector like this.
This is a fantastic example of how easy it is to just create code by hand that works just as well. It’s especially useful when you’re writing jQuery plugins because when you try to create a plugin without writing code, you end up spending way too much time debugging and figuring out why your plugin does what it does.
In this case, the code we wrote in the code box is much cleaner and easier to read. jQuery has come a long way in terms of how well it handles selector creation, but the good news is that it still has room to improve.
