Calling priority Nav, a lib that places the executing items inside a new drop-down, called "More", this dropdown is dynamically created in pure javascript as soon as it's needed. In it a button appears with class js-nav-toggle . I'm trying out some things, and I would like to change some things on that button, with pure javascript, I'm doing a test trying to find the js-nav-toggle class that is definitely in the document but only gives undefined.

I use this code that works fine on other elements that are written manually from the document. %code%

What could be happening?

The variable %code% is a list of nodes of class %code% :
%pre%
You can not change the list at once. It is necessary to iterate every element of the list, and you can do this %code% :
%pre%
But if it is only 1 element, you can use the index %code% :
%pre%
You can also use %code% (if it is only 1 element) or %code% (1 or more):
%pre%
While %code% also creates a list of nodes equally to %code% , and if it is only 1 element, you also use the %code% index:
%pre%
Or:
%pre%
However, if it is only 1 element, it makes more sense to use %code% :
%pre%
If it's just 1 element, it does not make sense to create a list of nodes.

Example:

%pre% %pre% %pre%

The variable %code% is a list of nodes of class %code% :

.priority-nav{
  background-color:red!important;
}

You can not change the list at once. It is necessary to iterate every element of the list, and you can do this %code% :

$(".priority-nav").css({
   backgroundColor:'red'
});

But if it is only 1 element, you can use the index %code% :

.priority-nav{
  background-color:red!important;
}

You can also use %code% (if it is only 1 element) or %code% (1 or more):

$(".priority-nav").css({
   backgroundColor:'red'
});

While %code% also creates a list of nodes equally to %code% , and if it is only 1 element, you also use the %code% index:

The variable list is a list of nodes of class .js-nav-toggle :

const list = document.getElementsByClassName("js-nav-toggle");

You can not change the list at once. It is necessary to iterate every element of the list, and you can do this for :

for(let x=0; x<list.length; x++){
   list[x].style.backgroundColor = "red";
}

But if it is only 1 element, you can use the index [0] :

list[0].style.backgroundColor = "red";

You can also use querySelector (if it is only 1 element) or querySelectorAll (1 or more):

document.querySelector(".js-nav-toggle");

While querySelectorAll also creates a list of nodes equally to getElementsByClassName , and if it is only 1 element, you also use the [0] index:

const list = document.querySelectorAll(".js-nav-toggle")[0];
list.style.backgroundColor = "red";

Or:

const list = document.querySelectorAll(".js-nav-toggle");
list[0].style.backgroundColor = "red";

However, if it is only 1 element, it makes more sense to use querySelector :

const list = document.querySelector(".js-nav-toggle");
list.style.backgroundColor = "red";

If it's just 1 element, it does not make sense to create a list of nodes.

Example:
