我需要Chrome扩展程序的帮助,我似乎无能为力。我能提供的大部分资源都没有太大帮助。我需要在这里编辑什么?

这是代码: HTML

JS:

// Quote generator
var strings = [
 'Only I can change my life',
 'Optimism is the faith that leads to achievement',
 'With the new day comes new strength and new thoughts',
 'Life is 10% what happens to you and 90% how you react to it',

];
var rand = strings[Math.floor(Math.random() * strings.length)];
document.getElementById('loading-text').innerHTML = rand;

// Loader
function timerOne() {
    myVar = setTimeout(showPage, 3000);
}

function showPage() {
  document.getElementById("loader").style.display = "none";
  document.getElementById("myDiv").style.display = "block";
}

// 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
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);

// Create a new list item when clicking on the "Add" button
function newElement() {
  var li = document.createElement("li");
  var inputValue = document.getElementById("myInput").value;
  var t = document.createTextNode(inputValue);
  li.appendChild(t);
  if (inputValue === '') {

  }
  document.getElementById("myInput").value = "";

  var span = document.createElement("SPAN");

清单:

   {
  "manifest_version": 2,
  "name": "Webapp",
  "version": "1.0",
  "description": "Webapp",
  "matches": ["<all_urls>"],
  "js": "script.js",
  "browser_action": {
  "default_icon": "image.png",
  "default_title": "Webapp",
  "default_popup": "webapp.html"
},
"permissions": ["tabs","activeTab"]
}

我不确定为什么代码无法正确加载。让我知道我该怎么办。 (如果可能,请发送当前代码的编辑版本。)
