When I format my code like this
const title = document.getElementById("title");
function handleClick() {
title.style.color = "red";
}
title.addEventListener("click", handleClick);
everything works fine. However, if I change it to this
const title = document.getElementById("#title");
function handleClick() {
title.style.color = "red";
}
title.addEventListener("click", handleClick);
it stops working. Can someone please explain why this is happening? Thank you.
It is important to remember that when using document.getElementById(), you must provide the exact id without any additional characters.
For example, if your HTML looks like this;
<div id='title'>My Title</div>
You would use document.getElementById("title") to access this element successfully.
On the other hand, using
document.getElementById("#title")const test_1 = document.getElementById('title');
const test_2 = document.getElementById('#title');
console.log(test_1); // This will output the correct element as the id matches
console.log(test_2); // This will output NULL as the id does not match properly<div id='title'>: is a symbol used in CSS selectors, but it cannot be utilized in JavaScript. Javascript typically finds elements by their ID through the
document.getElementById("ID"). to target classes in CSS, however, in JavaScript, you would need to access elements of a particular class with document.getElementsByClassName("CLASSNAME")document.getElementById("#id")id = "#id" rather than just id = "id".
Essentially, it can be explained that the symbol # serves as a separator for identifying ids in a similar way as the symbol . does for classes.
