For this assignment you need to create a ToDo list using Javascript, along with HTML and CSS.

Begin by creating a HTML page called todo.html. Then create a Javascript file called todo.js and link it in to the HTML page using a script tag. All Javascript for the assignment must be in the separate file. (For CSS, feel free to include styles in a style block at the top of the HTML page, or to link in CSS from a separate file).

On the todo.html page, create two blocks of content (see the attached diagram).

At the top of the page, create a HTML form with the label New Item.

  • The form should contain two elements: a textarea and a submit button.
  • The submit button should be disabled if there is no text in the textarea. Inputting text in the textarea should enable the button.
  • If the submit button is clicked while enabled, a new item should be added to the Item List section below the form. Once the item is added, the textarea should be cleared.

Below the form, create a block with the label Item List. This block will initially be empty.

When the submit button in the form is clicked, a new sub-block of content ('item block') should be created containing the following:

  • The text from the textarea in the form.
  • A timestamp below the text. This timestamp should be in a user-friendly format showing date and time (down to minute) that the item was created. This should be auto-generated based on the computer's local time.
  • A delete button in the upper right of the item block, floated to the right of the text. When the delete button is clicked, the entire item block should be deleted. (You can include an 'Are you sure' confirm dialog if you like.)

Additional item blocks should be appended after the first item in the list. Item blocks should stack vertically.
