17,538 Pointsnavigation.querySelector
Hi,
I am not sure how to solve it or what you wanna to do from me?
I tried to get the list by navigation.querySelector(ul.li);
or something like this but I don't fully understand your question.
Thanks,
//Select the naviagation
var navigation = document.getElementById("navigation");
//Select all listItems from the navigation
var listItems = navigation.querySelector("ul.li");
//When a navigation link is pressed
var linkListener = function() {
console.log("Listener is clicked!");
}
var bindEventsToLinks = function(listItem) {
//Select the anchor
var anchor = listItem;
//Bind the linkListener to the anchor element (a)
anchor.onclick = linkListener;
}
for(var i = 0; i < listItems.length ; i++) {
bindEventsToLinks(listItems[i]);
}

- because of the period, the selector "ul.li" would look for a UL that has the class "li". But you want to select the list items themselves ("ul li" or just "li").
- querySelector only returns the first item that matches. But you want the whole set (querySelectorAll).

It looks like it is asking you to use the .children selector:
var listItems = navigation.children;

Yes I got it but have no idea why children. It was not in any previous videos.
Thank you anyway.
