14,997 Pointsappending and removing elements
I'm still trying to work my way through the interactive web pages part :( It started off super simple, but the further along he goes the more confusing it gets!
I have got to the point in the video, where I am instructed to append elements in the 'appendchild' format, bindevents, and have done something with parent nodes. as far as I can see in comparing his code to mine, there's no difference...however as always there must be, as mine doesn't work and his does haha!
//User interaction does not get desired results
//add interactivity so the user can manage daily tasks
var taskInput = document.getElementById("new-task"); //new-task
var addButton = document.getElementsByTagName("button")[0]; //first button on the page
var incompleteTasksHolder = document.getElementById("incomplete-tasks"); //incomplete-tasks
var completedTasksHolder = document.getElementById("completed-tasks"); //completed-tasks
//new task list item
var createNewTaskElement = function (taskString) {
//create list item
var listItem = document.createElement("li");
//create an input check box
var checkBox = document.createElement("input");
//label
var label = document.createElement("label");
//input.edit
var editInput = document.createElement("input");
//button .edit
var editButton = document.createElement("button");
//button.delete
var deleteButton = document.createElement("button");
//each of these elements will need to be modifying
//and appended
listItem.appendChild(checkBox);
listItem.appendChild(label);
listItem.appendChild(editInput);
listItem.appendChild(editButton);
listItem.appendChild(deleteButton);
return listItem;
};
//add a new task
var addTask = function(){
console.log("Add task...");
//create a new list item with the text from the #new task
var listItem = createNewTaskElement("Some New Task");
//append list item to incomplete task holder
incompleteTasksHolder.appendChild(listItem);
bindTaskEvents(listItem, taskCompleted);
};
//edit existing tasks
var editTask = function(){
console.log("Edit task...");
//when the edit button is pressed
//if the class of the parent element is .editmode
//switch from .editmode
//make label text become the input's value
//else
//switch to .editmode
//input value becomes the label's text
//toggle .editmode on the parent
};
//mark tasks as complete
var taskCompleted = function(){
console.log("Task Complete...");
//append the task list item to the #completed-tasks
var listItem = this.parentNode;
completedTasksHolder.appendChild(listItem);
bindTaskEvents(listItem, taskIncomplete);
};
//delete tasks (existing)
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);
};
//mark task as incomplete
var taskIncomplete = function(){
console.log("Task incomplete...");
//append the list item to #incomplete-tasks
var listItem = this.parentNode;
incompleteTasksHolder.appendChild(listItem);
bindTaskEvents(listItem, taskCompleted);
};
var bindTaskEvents = function(taskListItem, checkBoxEventHandler){
console.log("Bind list item events");
//select listitems children
var checkBox = taskListItem.querySelector("input[type=checkbox]");
var editButton = taskListItem.querySelector("button.edit");
var deleteButton = taskListItem.querySelector("button.delete");
//bind the editTask to edit button
editButton.onclick = editTask;
//bind the deleteTask to the delete button
deleteButton.onclick = deleteTask;
//bind checkBoxEventHandler to the checkbox
checkBox.onchange = checkBoxEventHandler;
}
// set the click handler to the addTask function
addButton.onclick = addTask;
//cycle over incompleteTaskHolder ul li items
for(var i = 0; i < incompleteTasksHolder.children.length; i++) {
bindTaskEvents(incompleteTasksHolder.children[i], taskCompleted);
}
//cycle over completeTaskholder ul list items
for(var i = 0; i < completedTasksHolder.children.length; i++) {
bindTaskEvents(completedTasksHolder.children[i], taskIncomplete);
}

14,997 PointsOk...this was actually down to the emulator in Workspaces. I'm not sure what's going on with it, but when i copied my code into sublime, and opened it in chrome (which i was working in with workspaces too) it worked. All that stress for nothing
