I’m creating an Todo List with vanilla js and ran into a problem. When I click the recycle bin icon (within my span) I can’t delete my li.

They could point me the way so that I can do with javascript the fadeOut effect and then remove the li from my Todo list?? 

var itens = document.getElementsByClassName("item")

for(var i = 0; i < itens.length; i++){
    itens[i].addEventListener("click", function(){
       console.log("Me deleta")
    });
};

You can use const li = this.closest('li'); to know the <li> you want to remove and then li.parentElement.removeChild(li); to remove. This will change the DOM, if you have information about what is shown in an array for example you should change there as well...

To make the fadeout together a suggestion with an animation, you can create other

var itens = document.getElementsByClassName("item")

for (var i = 0; i < itens.length; i++) {
  itens[i].addEventListener("click", function() {
    const li = this.closest('li');
    li.classList.add('deletar');
    setTimeout(() => li.parentElement.removeChild(li), 800);
  });
};

  • I think he wants an effect of fadeout at the time of exclusion of the item.

    @Leandrade this is the easiest part and with more variants. But I added a suggestion, thank you.

  • Tip: modify the css by adding animation at height, so the animation is more fluid li {&#xA; opacity: 1;&#xA; transition: all .8s;&#xA; overflow:hidden;&#xA;}&#xA;&#xA;li.deletar {&#xA; height: 0;&#xA; opacity: 0;&#xA;}
