待办事项清单和清单项目计算javascript

Question

So, I've got to make a to-do list purely made from html,css and javascript,problem is, I've barely been taught any javascript at my school and even then,I haven't touched front-end in over a year So I'm quite stumbed here .. 所以，我要做一个完全由html，css和javascript制成的待办事项清单，问题是，我在学校几乎没有学过任何javascript，即使那样，我也没有碰过前端一年所以我在这里很绊脚..

The idea is that there should be an input field where I can add list items to my to-do list and once they're completed,I click on them and they get transfered to a "completed " section while also counting the percentage of how many list items are completed and not completed. 这个想法是，应该有一个输入字段，我可以在其中将列表项添加到待办事项列表中，完成后，我单击它们，然后将它们转移到“已完成”部分，同时还要计算许多列表项已完成但尚未完成。

I don't expect anyone to take the time to write out the code(though I would,obviously,appreciate it ),but atleast if I got some direction as to what parts of javascript I should look into,it'd be a great help as is.. 我不希望有人花时间写代码（尽管我会很欣赏），但是如果我对我应该研究的javascript部分有什么了解，那至少会很棒照样提供帮助..

If you are a student still I hope you take this and learn some more JS. 如果您还是一个学生，我希望您能学到这个并学到更多JS。 Me as a student starting in CS I was not able to begin to find out what to do. 作为一名从CS开始的学生，我无法开始做些什么。 I suggest recognizing the many js tools that there are and growing your knowledge. 我建议您认识其中存在的许多js工具并增加您的知识。 Try code academy for basic starting help. 请尝试代码学院以获取基本的入门帮助。

<!-- Super basic example with no styling and no counter -->
<html>
<body>
    <label>New Item</label>
    <input type="text" id="input">
    <button id="add">Add New To Do Item</button>
    <h1>To Do</h1>
    <ul id="toDoList">
    </ul>
    <h1>Completed</h1>
    <ul id="completedList">  
    </ul>
    <script>
        //calls when the page loads
        (function() {
            document.getElementById("add").addEventListener("click", function(){
                var newLi = document.createElement("li");
                var newDiv = document.createElement("Div");
                newDiv.innerText = document.getElementById("input").value;

                var newBtn = document.createElement("button");
                newBtn.innerText = "Done"
                newBtn.addEventListener("click", function(e){
                    e = e.target || e.srcElement;

                    //for some reason appending e.parentElement would not work so I had to create a brand new element
                    var newLi2 = document.createElement("li");
                    newLi2.innerText = e.parentElement.children[0].innerText;
                    document.getElementById("completedList").appendChild(newLi2);
                    e.parentElement.remove();
                })
                newLi.appendChild(newDiv);
                newLi.appendChild(newBtn);
                document.getElementById("toDoList").appendChild(newLi);
                document.getElementById("input").value = "";
            })
        })();
