Find the errors in the following

1.)

My script is loading fine, but separate style sheets aren't working

 <!DOCTYPE html>
	
<html>

	<head>
		<script src="/script/script.js"></script>
		<link src="stylesheet" type="text/css" href="/style/style.css">
	</head>

YOU MISSPELLED STYLSHEET

2.)

My scripts are loading, but they aren't working! How should I fix them? What's wrong?

<!DOCTYPE html>

<html>

<head>
	<script type="text/javascript" src="/script/script_1.js"></script>
	<script type="text/javascript" src="/script/script_2.js"></script>
</head>

CHANGED "text/script" to "text/javascript" 3.)

If the CLICK ME button is clicked twice what does the console display?

html (the error isn't here)

…

<button id="someId">CLICK ME</button>
…

…
var count = 0;
function clickAction(){
	count += 1;
	console.log("hello "+ count)
}

document.getElementById("someId").onclick = clickAction()
…

It displays 'Hello 1' in the console

4.)

What's the error?

function countPlusTenSquared(){
	var increment = 10;
	var count += increment;
	return count*count;
}

You're initializing count and changing its value at the same time. You need to declare it first and then use it.

5.)

Why is my form not working?

<form action="get" method="/">
	<input type="text" name="my_name">
	<input type="submit" value="submit name">
</form>

YOU SWITCHED ACTION AND METHOD

6.)

My double route isn't working! Why isn't the route working?

…
get "/double/:my_number" do
	
  input = params[:my_number]
  @double = 2*input
 
 erb :show
  
end

You need to convert input to an int before you double it

What does get "/double/2" return?

7.)

My greet route isn't working! What should I change?

app.rb

get "/greet/:name" do
	
	submitted_name = params[:name]
	
	erb :show
end

show.erb

<div>
	 Hello <%= submitted_name %>!
</div>

When I go to /greet/world expecting Hello World!, but I get the following error:

 NameError at `/greet/world`
undefined local variable or method `id' for
 #<Sinatra::Application:0x007f892315d160>
 
 BACKTRACE
 ____________________________________________
 2.		<%= submitted_name %>

submitted_name isn't an instance variable!!!! Change it to @submitted_name

8.)

Is this RESTful?

I have a site http://somelist.com that stores peoples names in a list.

I made the following routes

GET '/name/new'			# for showing a new form

GET '/name/create'		# for submiting a 'new' name form,
						# and creating
						
GET '/name/:id/delete'	# for submitting a deleting for a name

GET '/name/:id/edit			# for showing a new edit form

GET '/name/:id/edit/post'	# for submitting an edit
							# from a form

Please give a little explanation.

No, it's not RESTful. Instead of using the http methods like delete, patch, etc. you're only using GET and then recreating the functionality of those methods. I have no clue if this is correct, but I'm hoping it is.

9.)

What do you think of my controller? I don't even need a view. Why shouldn't I put all this in my controller?

get "/" do
	pageTitle = "myApp!"
	"<!DOCTYPE html>
	<html>
		<head>
				<title>#{pagetitle}</title>
		</head>
		<body>
				<div>
					Hello there!
				</div>
		</body>
	</html>"
end

pagetitle should be pageTitle in your html code.

10.)

Look at my view! This works, but why should I be doing things this way?

app.rb

get '/person/:name` do
	erb :show
end

show.erb

	<div>
		<% person = params[:name] %>
	
		Hello <%= person %>
	</div>

You should minimize the amount of ruby logic in your erb files and instead do the variable assignment in your main ruby file.
