Chore Door: step 8

[sylvesterhofstra]

Can someone explain me why both solutions to step 8 work? As far as I know the second one, which the task tells me to do, shouldn’t work, because I didn’t declare a ‘door1’ variable. So why does it work? And is the first solution better or doesn’t it matter?

Step 8

Inside the script.js file, underneath your global variable, assign door1.onclick to a new, empty arrow function.

Solution #1

let doorImage1 = document.getElementById("door1");
const botDoorPath = "https://s3.amazonaws.com/codecademy-content/projects/chore-door/images/robot.svg";

doorImage1.onclick = () => {
  doorImage1.src = botDoorPath;
};

Solution #2

let doorImage1 = document.getElementById("door1");
const botDoorPath = "https://s3.amazonaws.com/codecademy-content/projects/chore-door/images/robot.svg";

door1.onclick = () => {
  doorImage1.src = botDoorPath;
};

Thanks already for helping me out!

You are indeed correct. And it has been addressed to the staff multiple times. Your solution 1 is the proper one, the cause of solution 2 working may be in the back-end of the exercise. Other people ask the same question ;). Goed bezig!

Chore Door - Calling an element by ID without declaring it in Javascript

Hi. In this project we are asked to declare variables and setting them equal to some img elements gotten by ID. i.e.: let doorImage1 = document.getElementById('door1'); let doorImage2 = document.getElementById('door2'); let doorImage3 = document.getElementById('door3'); But also, sometimes in the instructions we are asked to use the id name in the code instead of the declared variable for that element. For example: Inside the script.js file, underneath your global variable, assign doo…

Cool, thnx! (And… bedankt voor de heads up!)

Just adding a bit more, I’m working on this project now and Solution 1 provided by @sylvesterhofstra doesn’t work at all for me, only Solution 2 works. Furthermore, the walk-through video uses solution 2 and as mentioned it’s not clear why how it even works as “door1” is never declared as a variable in the code.

Hey,

Could you provide your code so we can see if we can figure it out together ;)?
