当我的模式在localStorage中被定义为false时，如何防止预加载？

if (localStorage.getItem('mode') !== 'false') {
  // 执行预加载操作
}

if (localStorage.getItem('mode') !== 'false') {
  var image = new Image();
  image.src = 'path/to/image.jpg';
  document.head.appendChild(image);
  
  var script = document.createElement('script');
  script.src = 'path/to/script.js';
  document.head.appendChild(script);
  
  // 动态加载其他资源
}

async function preload() {
  if (localStorage.getItem('mode') !== 'false') {
    await loadResource('path/to/resource1');
    await loadResource('path/to/resource2');
    // 异步加载其他资源
  }
}

function loadResource(url) {
  return new Promise((resolve, reject) => {
    var resource = document.createElement('link');
    resource.rel = 'stylesheet';
    resource.href = url;
    resource.onload = resolve;
    resource.onerror = reject;
    document.head.appendChild(resource);
  });
}

preload();
