    If you're getting the cannot read/set display or contains error for the filterTodo function after the 54th minute, you can change the code as follows:
    function filterTodo(e) {
    const todos = todoList.childNodes;
    todos.forEach(function (todo) {
    const mStyle = todo.style;
    if(mStyle != undefined && mStyle != null){
    switch (e.target.value) {
    case "all":
    mStyle.display = "flex";
    break;
    case "completed":
    if (todo.classList.contains('completed')) {
    mStyle.display = 'flex';
    } else {
    mStyle.display = "none";
    }
    break;
    case "uncompleted":
    if (todo.classList.contains('completed')){
    mStyle.display = 'none';
    }
    else{
    mStyle.display = "flex";
    }
    break;
    }
    }
    })
    }
    Although I struggled for a long time, I could not solve this problem and my developer friend offered this solution. Thank you again here.

    Another way you could save the items into local storage is saving them as objects, along with the status i.e, {'text': 'todoText', 'status': 'complete'}. With some additional work you can then save the state of each todo item and set the necessary styling when refreshing the page. Great tutorial!

  • @sergiorejtman
    @sergiorejtman 3 ปีที่แล้ว +22

    Hey guys, there is a small LOGIC GAP here, if you set the filter to "uncompleted" and check a new item, that item will not hide immediately, as it should. The fix is simple: Inside function filterTodo(), instead of doing switch(e.target.value) you should do switch(filterOption.value). That will allow function filterTodo() to be called anytime, not only inside the 'click' event. Then you just add filterTodo(); as the last line inside the block "if (item.classList[0] === 'complete-btn')" inside function deleteCheck(). That will call funtion filterTodo() right after the item is checked, updating the screen!

      @utsavkashichhwa ปีที่แล้ว

      There is still another problem. When you set filter to 'complete' then add a new item, the item will not hide immediately. The first thing is to modify the filterTodo() function, like mentioned above, so it can be used without the event argument. Then make sure to call the filter funtion when you change the filter, add a new todo, or change the state of a todo by adding event listeners to the relevent elements: [filterOption, todoButton, todoList].forEach((element) => element.addEventListener('click', filterTodos));.

    • @danielmbirch
      @danielmbirch ปีที่แล้ว +1

      This works great, thank you. The only issue I'm having is the select field only actions the second time you click it. Click once to get the drop down, select an item (nothing happens yet) but click on the select element again and the selection you previously made actions. Anyone have any ideas? My code is the same as the tutorial, checked many times over, I'm thinking since this tutorial was made 2+ years ago, there have been browser or JS changes which is causing this??

    I got stuck by the minute 48 when toggling the completed to-dos, for a reason the children in the nod list were undefined. After hours of checking my code line by line, I solved it by replacing my HTML body with the one from your repo. Although it was the very same code, except for one space between the footer and the script tag. Didn't know what could have been wrong with mine.
    Great video!!! I enjoyed it so much.

      but it is not clearly mention that why this issue happened , for anyone facing this problem can select all and press shift + alt + f ,
      in short : " ctrl + a " and then " shift + alt + f "
      do check if it works

    In the filtering part, for some reason my todoList.childNodes contained an extra "text" node in addition to the various divs representing todo items. This was causing it to break so I added an additional if statement to filter those out:

    if (todo.nodeType == Node.ELEMENT_NODE) {
    switch(e.target.value) {

    For those who can't do the filter function at 53:34
    Here is the code
    ```HTML Code
    DS Todo List








    All
    Completed
    Uncompleted





    ```JS Code
    filterOption.addEventListener('click', filterTodo);
    function filterTodo(e) {
    const todos = todoList.childNodes;
    todos.forEach(function(todo) {
    if (todo.nodeType == Node.ELEMENT_NODE) {
    switch(e.target.value) {
    case "all":
    todo.style.display = "flex";
    break;
    case "completed":
    if (todo.classList.contains('completed')) {
    todo.style.display = 'flex';
    } else {
    todo.style.display = "none";
    }
    break;
    case "uncompleted":
    if (todo.classList.contains('completed')){
    todo.style.display = 'none';
    }
    else{
    todo.style.display = "flex";
    }
    break;
    }
    }
    })
    }
    Possible errors on your side:
    1) The space in can cause error. Remove the space between the and
    2) For filterOption.addEventListener('click', filterTodo); some said changing from 'click' to 'input' or 'change' helps. Click works just fine for me tho.
    3) Add extra code to your function filterTodo(e), add this : if (todo.nodeType == Node.ELEMENT_NODE) {
    full code is as shown as above.
    If above method does not work, could be just a type error. Try copy and paste my code and see if it works.
    Hope this helps. Happy Coding guys =)

    Hey, awesome video,
    But I also wanna talk about a little problem that I saw.
    At 1:10:33 you're deleting a "todo" element by looking for it by the element text, and if you'd have the same element twice then it's gonna remove the very first element.
    My solution for that is to delete a text from the todos array by the index of the element, which is supposed to be with the same index in the todos array, just like that:
    const todoIndex = Array.from(todosList.childNodes).indexOf(todo);
    todos.splice(todoIndex, 1);
    And now, even if you had the same text in the todos list, it would delete the specific todo element that you have clicked on.

    If you're getting the cannot read/set display or contains error for the filterTodo function after the 54th minute it's bc you have to check if the starting "ul" and the closing "ul" in line 30 of the index IS IN THE SAME LINE and that the closing ul is not a line below bc if it is it'll take "text" as first child and mess up the childNodes which is why u get this error.

    While I value you teaching people web development, you really should make sure you don't teach people bad practices. div cannot be a child of ul, that's invalid HTML. ul can only have li, template, and script children. textContent should always be preferred over innerText unless you need the specific, white-space preserving behaviour of innerText. Also you should stick to one style of denoting strings, either double or single quote. For HTML strings I recommend to use template literals so you don't have issues with quotes inside the string (which seems to be the reason you're using single quotes for those).

    At the end of the video Dev Ed said it is difficult to implement. But it is not so difficult.
    Instead of storing the item text alone to local storage, i'm storing the following object, where status is completed/uncompleted.
    class TODOItem {
    constructor(text, status) {
    this.text = text;
    this.status = status;
    }

    Absolutly best vide which learned me lot of things. But anyway.... I have some improvements of application. But the problem is, that you compare value of "li" element with the actual "todo" when you're getting indexOf if you're removing todo from totos (splice of array). The problem is when you have 2 todo's with the same name. Probably ID or data-label can resolve this problem. data-label could be UUID or just some ID. But, really hard work and very good course.

    todos.forEach(function (todo) {
    with:
    function filterTodo(e) {
    const todos = [...todoList.children];
    todos.forEach(function (todo) {
    childNodes returns a collection of - as it sounds like - child 'nodes'. Some of these nodes may not be elements, but text nodes - and text nodes have no classList property. Use .children instead, which will retrieve only child 'elements'.

      Basically, it's not sufficient to store only the todo content to the local storage. You'll also have to store a boolean indicating whether it is completed, and then render the style accordingly. Instead of storing todos = ["learn javascript", "get up early", "hello"], you need to store something like todos = [{content: "Learn javascript", completed: false}, {content: "get up early", completed: true}, {content: "hello", completed: true}].

    ....UPDATE: I just cloned the repo from Dev ED, and his code has the same bug. It could have something to do with my Browser. I am running Chrome....
    The problem seem to be that. the filterToDo function does not fire when i press the options in the drop down menu, only when I press the select element does the function fire

      I have the same problem. I think the error occurs, because if you check what console.log(todos) does after the "const todos = todoList.childnodes;" line, then you'll see, that we have an unneccesary element in the NodeList.
      Even though you add 0, 1, 2 or 3.... items, there will be always 1 more in the NodeList, because the first one will be a 'text' element, like this:
      NodeList(3) [text, div.todo, div.todo]
      I'm not sure why does it gets added. It has a wholeText: "↵↵ ". I'd also appreciate some insight if someone has. :)

    Thanks so much for such great project. It took me several days to understand each part of it, to make a lot of notes and even to add some new features!!! You are going a great job! Will be waiting new projects
