3,970 PointsTo Do App Question
This is from the to do app intermediate course done with JS only. The pen can be viewed here: http://codepen.io/bluehabit/pen/adBEjr
My question is what within the code is specifically targeting the edit and delete buttons for the tasks? The other buttons are stored within variables for instance:
var taskInput = document.getElementById('new-task');//new-task
var addButton = document.getElementsByTagName('button')[0]; //first button 'add'
These variables are then later used in functions.
However, with the edit and delete buttons, I do not see any variables, all I see are functions such as:
var deleteTask = function() {
console.log("Delete task...");
var listItem = this.parentNode;
var ul = listItem.parentNode;
//Remove the parent list item from the ul
ul.removeChild(listItem);
}
How is this program specifically targeting the edit and delete buttons?

19,699 PointsIf you look at line 126 in your CodePen code, you wrote
deleteButton.onclick = deleteTask;
which hooks the deleteTask function to the deleteButton, so the code inside deleteTask will run when the deleteButton is clicked.
