Strikeout list on click of a mouse

Question

Strikeout list on click of a mouse

Is there a way to apply strikethrough formatting to text with just a mouse click? The CSS for lists is beyond the form field margin. I've tried multiple methods without success. No matter how many times I change the code, I can't seem to get it right. I've extensively searched the site for a solution to no avail. I attempted to troubleshoot but couldn't find anything to resolve this issue

$(document).ready(function() {

  $('form').on('submit', function(e) {
    e.preventDefault();

    const taskList = $('#task-list').val();
    const newItem = $('<li></li>');

    $(`<li>${taskList}</li>`).appendTo(newItem);
    $(newItem).appendTo('ul');
    $("li").click(function() {
      $(this).addClass("striked-through");
    });
    $('#task-list').val("");
  });
});

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: Roboto, sans-serif;
}

.container {
  margin: 100px auto;
  max-width: 640px;
  width: 100%;
}

form {
  margin-top: 40px;
}

input,
textarea,
button {
  display: block;
  padding: 8px;
  margin-bottom: 8px;
  width: 100%;
  resize: none;
}

button {
  background-color: #2e9ccc;
  border: none;
  text-transform: uppercase;
  color: #fff;
  font-weight: bold;
  font-size: 18px;
  font-style: italic;
  cursor: pointer;
}

button:hover {
  background-color: #18a9e9;
}

input:focus,
textarea:focus {
  outline-color: #18a9e9;
}

ul {
  text-decoration: line-through;
}
