addButtonListeners
a. Selects all buttons nested inside the main element
b. If buttons exist:
c. Loop through the NodeList of buttons
d. Gets the postId from button.dataset.postId
e. If a postId exists, add a click event listener to the button (reference
addEventListener) - inside the loop so this happens to each button
f. The listener calls an anonymous function (see cheatsheet)
g. Inside the anonymous function: the function toggleComments is called with the
event and postId as parameters
h. Return the button elements which were selected
i. You may want to define an empty toggleComments function for now. The listener
test will NOT pass for addButtonListeners until toggleComments is completed.
Nevertheless, I recommend waiting on the logic inside the toggleComments
function until we get there.
const addButtonListeners = function()
{
const buttons = document.querySelectorAll("main")[0].querySelectorAll(`button`);
buttons.forEach((button) =>
{
const postID = button.dataset.postId;
button.addEventListener("click",function()
{
toggleComments(postID);
})
})
return buttons;
}
function toggleComments(postID)
{
}
This is what I currently have but I need the function addButtonListeners should add a click listener that calls the toggleComments function to each button element found within the main element.
