you can’t do this, the second argument of addEventListener needs to be a function, like this it is undefined as that is what is returned by displayStory

3

what about this.
scaryStoryBtn.addEventListener(“click”, displayStory=genre=>{
if (storyObj.hasOwnProperty(genre)) {
resultParagraph.textContent = storyObj[genre].story;
storyContainer.style.borderColor = storyObj[genre].borderColor;
}}
);
funnyStoryBtn.addEventListener(“click”, displayStory=genre=>{
if (storyObj.hasOwnProperty(genre)) {
resultParagraph.textContent = storyObj[genre].story;
storyContainer.style.borderColor = storyObj[genre].borderColor;
}
});
adventureStoryBtn.addEventListener(“click”, displayStory=genre=>{if (storyObj.hasOwnProperty(genre)) {
resultParagraph.textContent = storyObj[genre].story;
storyContainer.style.borderColor = storyObj[genre].borderColor;
}});

you are definind displayStory again, please don’t do that, use the one that already exist

you are getting nearer, but you may want to try with an anonymous function

5

I still dont understand what you mean

6

Hi there. Try arrow function within the event listener.

7

can you be more specific of what you don’t understand?

  • you need to call displayStory when the function is clicked
  • you can’t give displayStory as argument of addEventListener because you need to give it an argument
  • you need to give a function to addEventListener anyway
  • I suggested an anonymous function
