Filter Task List with buttons (with metod filter)

172 Views Asked by At

I need to filter with this method the tasks that have been completed, those that are not completed and that all appear, interacting with the three buttons; to be able to filter these tasks with these filters and that only the correct ones come out, it is the only functionality that my task list lacks.

window.addEventListener("load", () => {
  let id = 0;
  let text = "";
  let alert = document.querySelector(".alert");
  let alertGreen = document.querySelector(".alert-green");
  let close = alert.firstElementChild;
  let input = document.querySelector("#task");
  let arrow = document.querySelector(".arrow");
  let done = document.querySelectorAll(".fa-circle-check");
  let trash = document.querySelectorAll(".fa-trash");
  let edit = document.querySelectorAll(".fa-pencil");
  let task = document.querySelectorAll(".task");
  let btnAll = document.querySelector(".btn");
  let btnToDo = btnAll.nextElementSibling;
  let btnDone = btnToDo.nextElementSibling;
  let taskArray = [].slice.call(task);
  console.log(taskArray);



  close.addEventListener("click", () => {
    alert.classList.add("dismissible");
  });
  input.addEventListener("focus", () => {
    document.addEventListener("keydown", (event) => {
      // console.log(event.code);
      if (event.code == "Enter" || event.code == "NumpadEnter") {
        event.preventDefault();
      }
    });
  });
  //Alert Verde con temporizador
  arrow.addEventListener("click", (event) => {
    if (input.value.trim() !== "") {
      alertGreen.classList.remove("dismissible");
      setTimeout(() => {
        alertGreen.classList.add("dismissible");
      }, 5000);
    }
    if (input.value.trim() == "") {
      //Trim elimina los espacios al inicio y al final del string
      // console.log("Empty");
      event.preventDefault();
      input.value = "";
      alert.classList.remove("class", "dismissible");
    } else {
      let text = input.value;
      input.value = "";
      id =
        Number(document.querySelector("tbody")?.lastElementChild?.id) + 1 || 0;
      //?? operador condicional?? por si no existe o está vacío

      //Creando una nueva fila

      document.querySelector("tbody").appendChild(generateRow(id, text));
      if (!alert.classList.contains("dismissible")) {
        alert.classList.add("dismissible");
      }
    }
  });
  done.forEach((item) => {
    item.addEventListener("click", (e) => {
      deleteTask(e);
    });
  });
  trash.forEach((item) => {
    item.addEventListener("click", (e) => {
      removeRow(e, false);
    });
  });
  edit.forEach((item) => {
    item.addEventListener("click", (e) => {
      editTask(e, false);
    });
  });
  task.forEach((item) => {
    item.addEventListener("focus", (e) => {
      editTask(e, true);
    });
  });
});

Next time please attach a copy of a task object.

You can use filter() function like this :

function filterTasksCompleted(tasks) {
   return tasks.filter(task => task.isComplete); //return array with only tasks which have isComplete = true key.
}
