如果单击 div 但从其他元素中删除相同的元素，如何添加元素？

Question

I have an onclick function that add an element if a div is clicked

function clickOnADivToCreateLi(element) {
  var div = $(element);
  var i = document.createElement("i");
  $(i).addClass("fas fa-check-circle clicked");
  div.append(i);
}

But when I click on another div with the same class, I have two div with the same <i> and if I click again that div will have 2 <i> s

How do add the <i> but at the same time remove it from the others?

Answer 1

Select the i elements matching the classes you assigned to it and call remove() before creating the new instance.

Also note that your code can be made much more succinct:

function clickOnADivToCreateLi(element) {
  $('i.fas.fa-check-circle.clicked').remove();
  $(element).append('<i class="fas fa-check-circle clicked" />');
}
