Question

What is the process for incorporating a new task into my HTML/CSS/JavaScript to-do list application when the Enter key is pressed?

Currently, I am working on developing a to-do list application using HTML, CSS, and JavaScript. The application includes a text input field for users to enter their tasks, along with an "Add Task" button. However, I want to enhance the user experience by allowing them to add tasks simply by hitting the Enter key on their keyboard.

How can I integrate this feature into my application? Which event listeners or key codes should I use to detect when the Enter key is pressed and activate the task addition function? Additionally, how can I ensure that the input field is cleared after a task has been added?

Your guidance, code snippets, or recommended strategies would be greatly appreciated in helping me achieve this functionality. Thank you in advance for your assistance!

Currently, the only way to add tasks is by clicking on the button.

To enable users to input tasks by hitting the Enter key, you can attach an event listener to the input field that monitors the "keydown" event. When the Enter key is pressed, a function can be triggered to add the task to the list.

The code snippet below illustrates how you can implement this functionality:

<input type="text" id="taskInput">
<button id="addTaskBtn">Add Task</button>

<script>
  const taskInput = document.getElementById("taskInput");
  const addTaskBtn = document.getElementById("addTaskBtn");

  taskInput.addEventListener("keydown", function(event) {
    if (event.key === "Enter") {
      addTask();
    }
  });

  addTaskBtn.addEventListener("click", function() {
    addTask();
  });

  function addTask() {
    const task = taskInput.value;
    if (task.trim() !== "") {
      // Add task to the list
      console.log("Task added:", task);
      taskInput.value = "";
    }
  }
</script>

const taskInput = document.getElementById("taskInput");
const addTaskBtn = document.getElementById("addTaskBtn");

taskInput.addEventListener("keydown", function(event) {
  if (event.key === "Enter") {
    addTask();
  }
});

addTaskBtn.addEventListener("click", function() {
  addTask();
});

function addTask() {
  const task = taskInput.value;
  if (task.trim() !== "") {
    // Add task to the list
    console.log("Task added:", task);
    taskInput.value = "";
  }
}

<input type="text" id="taskInput">
<button id="addTaskBtn">Add Task</button>
