JavaScript Todo Application

I created a ToDo application similar to what was made in a previous course here on TreeHouse. A lot of the code is similar except I need the text inputs to save when the users hits the enter key. The initial add/submit button works fine but the edit does not toggle when the user is focused and hits enter. To be more clear what I want: the users hits edit, modifies the field, then can hit enter to leave the field and save the edit.

Below is a link to all the code. The code specific to the keyboard events is at the very bottom of the javascript section.

Thanks in advance to anyone that can help!!

You don't have a keyup event listener for the input field(s).

I see some code that starts with ...

document.getElementsByTagName("input")[2].addEventListener("keyup", ...

Perhaps this is intended to to create a keyup listener for the input field, but these have not been created yet at page load time. This should be done individually (with slight modification) in the TaskEvents function, or collectively with a delegated handler.

Steven,

Thank you so much!! You got it exactly. I had put the event handler outside the functions and they only ran one time when the page loaded, before the list items were created. I move the event handler inside the " add task" function and attached it to each new item when it was created.

Thanks again for the advice and prompt response! You really helped me out. I had spent several hours tinkering with it before asking and you saved me many more.
