Still learning so bear with me.
I am building a test project where I have a simple input that I show it on the same page as a list. (grocery or to do list project)
So when a user hits the ok button I create a new li inside a ul element. That goes ok.
I want to implement the following though: When the user clicks on the new element (li) I want to change the text decoration to line-though and show a trash icon where it will remove this li element by clicking on it.
I have managed to do that. The problem is that when the user clicks again on the new element (li) I get a second trash image.
I want help to succeed in this: when a user clicks on the element while it has text-decoration = line-through to hide or remove the trash icon and make text-decoration none again.
Here is a code pen for this project to check out. Just insert a new item on the list and then click twice on it: https://codepen.io/dourvas-ioannis/pen/MWVBjNZ
This is the function I am using when the user hits the add button to add a list item:
function addToList(){
let newListItem = document.createElement('li');
newListItem.textContent = userInput.value;
list.appendChild(newListItem);
userInput.value = "";
newListItem.addEventListener('click', function(){
this.style.textDecoration = 'line-through';
let itemButton = document.createElement('a');
itemButton.setAttribute('href', '#');
itemButton.classList.add('trash-image');
itemButton.innerHTML = '<i class="material-icons">delete</i><a/>';
itemButton.addEventListener("click", deleteOneItem);
this.appendChild(itemButton);
});
}
function deleteOneItem(){
this.parentNode.remove();
}
