A To-Do List is a tool for organizing tasks, allowing users to list, prioritize, and manage their activities, ensuring efficiency and productivity in completing them. Here we will create a ToDo list using Bootstrap. We will create our layout or component using Bootstrap predefined utilities and components. We will add custom JavaScript for the behavior of the to-do list.
Preview:
Approach
- We are creating an input field with the help of Bootsrap input-group.
- Then we are creating a list-group that will add out to do list into it.
- we are creating a submit button that will add the task into the list. we are writing our logic to add the task into list in the javascript.
- On submiting the typed text into the input field the function will be called and it will add the task into the list that was created before by the use of bootstrap.
- Also, it will add two buttons with the task, one button is for editing the task and another one is for deleting the task.
- If user clicks the editing button it will unable to option to edit the task by calling a function and that editing button will change itno save button after editing the user can save that.
- If the user clicks the delete button it will call the function and it will remove the task from the list.
- as the project does not using any kind of storage so it will be disappear once the browser will reload.
- We have shown three default task at the first so that user can make changes by using those task to check the working of the app.
