#Debugging (Use The Duck… )

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="sytlesheet" type="text/css" href="/style/style.css">
    </head>

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

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>
…

JS

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

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

4.)

What's the error?

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

5.)

Why is my form not working?

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

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

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 %>

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.

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

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>
