如何创建充当待办事项列表的WordPress插件

Question

我想知道如何创建充当待办事项列表的WordPress插件？

我是WordPress的新手，我想像WordPress插件一样创建一个待办事项列表：

def foo(varA, varB):
    if not (varA or varB):
        return False

    if varA:
        for test1 in test2:
            # Perform Action A

    if varB:
        for test1 in test2:
            # Perform Action B

    return True

//Document is the DOM can be accessed in the console with document.window.
// Tree is from the top, html, body, p etc.

//Problem: User interaction does not provide the correct results.
//Solution: Add interactivity so the user can manage daily tasks.
//Break things down into smaller steps and take each step at a time.


//Event handling, uder interaction is what starts the code execution.

var taskInput=document.getElementById("new-task");//Add a new task.
var addButton=document.getElementsByTagName("button")[0];//first button
var incompleteTaskHolder=document.getElementById("incomplete-tasks");//ul of #incomplete-tasks
var completedTasksHolder=document.getElementById("completed-tasks");//completed-tasks


//New task list item
var createNewTaskElement=function(taskString){

	var listItem=document.createElement("li");

	//input (checkbox)
	var checkBox=document.createElement("input");//checkbx
	//label
	var label=document.createElement("label");//label
	//input (text)
	var editInput=document.createElement("input");//text
	//button.edit
	var editButton=document.createElement("button");//edit button

	//button.delete
	var deleteButton=document.createElement("button");//delete button

	label.innerText=taskString;

	//Each elements, needs appending
	checkBox.type="checkbox";
	editInput.type="text";

	editButton.innerText="Edit";//innerText encodes special characters, HTML does not.
	editButton.className="edit";
	deleteButton.innerText="Delete";
	deleteButton.className="delete";

	//and appending.
	listItem.appendChild(checkBox);
	listItem.appendChild(label);
	listItem.appendChild(editInput);
	listItem.appendChild(editButton);
	listItem.appendChild(deleteButton);
	return listItem;
}



var addTask=function(){
	console.log("Add Task...");
	//Create a new list item with the text from the #new-task:
	var listItem=createNewTaskElement(taskInput.value);

	//Append listItem to incompleteTaskHolder
	incompleteTaskHolder.appendChild(listItem);
	bindTaskEvents(listItem, taskCompleted);

	taskInput.value="";
}

//Edit an existing task.

var editTask=function(){
	console.log("Edit Task...");
	console.log("Change 'edit' to 'save'");

	var listItem=this.parentNode;

	var editInput=listItem.querySelector('input[type=text]');
	var label=listItem.querySelector("label");
	var containsClass=listItem.classList.contains("editMode");

	//If class of the parent is .editmode
	if(containsClass){
		//switch to .editmode
		//label becomes the inputs value.
		label.innerText=editInput.value;
	}else{
		editInput.value=label.innerText;
	}

	//toggle .editmode on the parent.
	listItem.classList.toggle("editMode");
}

//Delete task.
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 completed
var taskCompleted=function(){
	console.log("Complete Task...");
	
	//Append the task list item to the #completed-tasks
	var listItem=this.parentNode;
	completedTasksHolder.appendChild(listItem);
	bindTaskEvents(listItem, taskIncomplete);
}


var taskIncomplete=function(){
	console.log("Incomplete Task...");
	//Mark task as incomplete.
	//When the checkbox is unchecked
	//Append the task list item to the #incomplete-tasks.
	var listItem=this.parentNode;
	incompleteTaskHolder.appendChild(listItem);
	bindTaskEvents(listItem,taskCompleted);
}

var ajaxRequest=function(){
	console.log("AJAX Request");
}

//The glue to hold it all together.

//Set the click handler to the addTask function.
addButton.onclick=addTask;
addButton.addEventListener("click",addTask);
addButton.addEventListener("click",ajaxRequest);

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 editTask to edit button.
	editButton.onclick=editTask;
	//Bind deleteTask to delete button.
	deleteButton.onclick=deleteTask;
	//Bind taskCompleted to checkBoxEventHandler.
	checkBox.onchange=checkBoxEventHandler;
}

//cycle over incompleteTaskHolder ul list items
//for each list item
for (var i=0; i<incompleteTaskHolder.children.length;i++){
	//bind events to list items chldren(tasksCompleted)
	bindTaskEvents(incompleteTaskHolder.children[i],taskCompleted);
}

//cycle over completedTasksHolder ul list items
for (var i=0; i<completedTasksHolder.children.length;i++){
	//bind events to list items chldren(tasksIncompleted)
	bindTaskEvents(completedTasksHolder.children[i],taskIncomplete);
}

// Issues with usabiliy don't get seen until they are in front of a human tester.

//prevent creation of empty tasks.

//Shange edit to save when you are in edit mode.

但这是JavaScript，我希望将其作为WordPress插件的版本。

有人会对如何做有任何想法吗？
