Hello. I'm trying to make a simple Google Chrome Extension that is a task list. So far everything works except two things. 1. When the user clicks the little "x" to delete the task, nothing happens. The task should be deleted from the list. 2. When the extension is closed, or the browser is closed, the list resets back to an empty slate. I'm not sure how to impliment any type of storage. Can someone help me out? Thank you!! manifest.json: ------------------ { "name": "ToDo Task List", "description": "Allows user to enter in tasks to a list", "version": "1.0", "manifest_version": 2, "permissions": ["alarms", "notifications", "storage"], "browser_action": { "default_icon": "icon16.png", "default_title": "To-Do List", "default_popup": "popup.html" }, "icons": { "128": "icon128.png", "48": "icon48.png", "32": "icon32.png", "16": "icon16.png" } } -------------------------- popup.html -------------------------

// Add new list item javascript command document.addEventListener('DOMContentLoaded', function() { document.getElementById('addButton').addEventListener('click', newElement); });

var span = document.createElement("SPAN"); var txt = document.createTextNode("\u00D7"); span.className = "close"; span.appendChild(txt); li.appendChild(span);

for (i = 0; i < close.length; i++) { close[i].onclick = function() { var div = this.parentElement; div.style.display = "none"; } }

// Create a "close" button and append it to each list item var myNodelist = document.getElementsByTagName("LI"); var i; for (i = 0; i < myNodelist.length; i++) { var span = document.createElement("SPAN"); var txt = document.createTextNode("\u00D7"); span.className = "close"; span.appendChild(txt); myNodelist[i].appendChild(span); }

// Click on a close button to hide the current list item function deleteTask(){ var close = document.getElementsByClassName("close"); var i; for (i = 0; i < close.length; i++) { close[i].onclick = function() { var div = this.parentElement; div.style.display = "none"; } } }

// Add a "checked" symbol when clicking on a list item var list = document.querySelector('ul'); list.addEventListener('click', function(ev) { if (ev.target.tagName === 'LI') { ev.target.classList.toggle('checked'); } }, false); }
