everyone.
I am using bootstrap modal. I am going to design a login in function in the modal.
There is a function of data checking.
However, the word ‘br’ show directly in html. I just want a line break effect.
When the user name is empty and password is <6 letters,
My html show:
User Name can not be empry br At least 6 letters for password
It seems the br tag does not work.
<!doctype html>
<html lang="en">
<head>

>Solution :
errorDiv.innerText = errorMessage
You are changing the text, not the HTML. Change that to:
errorDiv.innerHtml = errorMessage
