(I wrote this using Google Translate. Please forgive the grammar.)
Hello!
This is the 11th challenge.
From this challenge, you will finally be able to use JavaScript! I started learning the basics of JavaScript a few days ago, so there are many things I don't know completely.
So this challenge was too difficult for me as I am new to JS.
Here are the things that were difficult while working this time:
- An error message is displayed when a blank or incorrect character is entered, but I want to press the message only once.
Is there any way to make the error message appear only once? And if I input a normal message, is there a way to clear the error message?
- I set the style.border value to change so that the color of the border of the input also changes when an error message is applied to the JS function, but it didn't work.
Is there any way to solve this?
It's my first challenge, but I'm glad I learned a little bit about how to read JS code through this work! There were many shortcomings, but I will continue to study hard!
Thank you for watching! > β½<)/ If you have any other advice, please feel free to tell me!

Hello!
In your
outputmessage(self)
functionvar message; message = document.createTextNode(self); errormsg.appendChild(message);
you can remove these lines and instead of that, add
errormsg.textContent = self
. This will change the text of that element.The reason why border color is not applying is because in this line
var address = document.querySelector('[name="email"]').value
you are getting value of the element instead of the actual element (remove.value
), and then addaddress.style.borderColor = 'any color'

π Hello Drunken Neoguri , nice to see you complete another challenge with a great solution, well done π€©π€©π€©
If I have understood correctly your question then a easy solution is to add a
change
event listener to the email input & then check there if email matches then show error message else hide it. Another way to deal that is whenever the Notify Mebutton
is clicked then check the & display/hide the error message. Here is the code for this approach (please change it according to your code):const emaiInput = document.querySelector("input"); const emailChecker = /\S+@\S+\.\S+/; document.querySelector("button").addEventListener("click", () => { if (!emailChecker.test(emaiInput.value)) { emaiInput.classList.add("error"); document.querySelector(".error-message").style.display = `block`; setTimeout(() => { document.querySelector(".error-message").style.transform = `scale(1)`; }, 100); } else { if (emaiInput.classList.contains("error")) { emaiInput.classList.remove("error"); document.querySelector(".error-message").style.transform = `scale(0)`; setTimeout(() => { document.querySelector(".error-message").style.display = `none`; }, 300); } } });
Hope this helps π€ and please code amazing solutions like this π
