Hello.
I have done the exact same as in the code in the video, but when i click on down button it does not work anyway. Up and Remove works but down refuses to respond.
can u please check and see?
listUl.addEventListener("click", (event) => { if(event.target.tagName == "BUTTON"){
if(event.target.className == "remove"){
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
if(event.target.className == "up"){
let li = event.target.parentNode;
let prevLi = li.previousElementSibling;
let ul = li.parentNode;
if(prevLi){
ul.insertBefore(li,prevLi);
}
if(event.target.className == "down"){
let li = event.target.parentNode;
let nextLi = li.nextElementSibling;
let ul = li.parentNode;
if(letLi){
ul.insertBefore(nextLi, li);
}
}
}
} } );

if(prevLi){
ul.insertBefore(li,prevLi);
}
But not the big if-statement. I'm guessing the other statement isnt suppose to go into the second if? If it is it should be an else if. Hope this helps.
So this:
if(event.target.className == "remove"){
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
if(event.target.className == "up"){
let li = event.target.parentNode;
let prevLi = li.previousElementSibling;
let ul = li.parentNode;
if(prevLi){
ul.insertBefore(li,prevLi);
}
if(event.target.className == "down"){
let li = event.target.parentNode;
let nextLi = li.nextElementSibling;
let ul = li.parentNode;
if(letLi){
ul.insertBefore(nextLi, li);
}
}
}
Should probably be:
if(event.target.className == "remove"){
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
if(event.target.className == "up"){
let li = event.target.parentNode;
let prevLi = li.previousElementSibling;
let ul = li.parentNode;
if(prevLi){
ul.insertBefore(li,prevLi);
}
}
if(event.target.className == "down"){
let li = event.target.parentNode;
let nextLi = li.nextElementSibling;
let ul = li.parentNode;
if(letLi){
ul.insertBefore(nextLi, li);
}
}

Full Stack JavaScript Techdegree Student 12,427 PointsThank you Andreas! I missed that totally! Good notice there!

Courses Plus Student 3,339 PointsNow I can appreciate why we should format nested braces properly. Each for, if, etc statement should have a brace directly below it to ensure you don't miss any.
