Javascript 谷歌浏览器存储节省

因此，我创建了一个选项页面，并试图将表单的值保存到存储器中，但我不断收到控制台错误“UncaughtTypeError:无法读取undefined的属性“sync”

HTML格式：

    <h3 class="option">When Search Tab is opened the Search Panel should be:</h3>
    <select id="searchPanel" class="selectOption">
        <option value="open">Open</option>
        <option value="closed">Closed</option>
    </select>

    <h3 class="option">The Search Bar Background Color Should Be:</h3>
    <select id="barBackground" class="selectOption">
        <option value="#000000">Black</option>
        <option value="#ffffff">White</option>
        <option value="#333333">Grey</option>
        <option value="#006633">Green</option>
        <option value="#336699">Blue</option>
        <option value="#990000">Red</option>
        <option value="#CC6600">Orange</option>
    </select>

    <h3 class="option">The Search Bar Text Color Should Be:</h3>
    <select id="barColor" class="selectOption">
        <option value="#000000">Black</option>
        <option value="#ffffff">White</option>
        <option value="#333333">Grey</option>
        <option value="#006633">Green</option>
        <option value="#336699">Blue</option>
        <option value="#990000">Red</option>
        <option value="#CC6600">Orange</option>
    </select>

编辑： 新错误消息：

拒绝执行内联事件处理程序，因为它违反了以下内容安全策略指令：“script src‘self’”。启用内联执行需要'unsafe inline'关键字、哈希（'sha256-…'）或nonce（'nonce-…'）。

您是否声明了

“存储”

权限？是的，我刚刚添加了我的清单您是如何测试它的？它加载，然后我更改三个表单按钮的值，然后单击“保存”（这会触发saveOptions（））它在控制台中给了我一个错误。我的意思是，你是否正确地重新加载了扩展，然后通过选项链接打开了页面？我知道这很愚蠢，但我正试图消除“我直接打开了html文件”的场景。换句话说，打开页面时显示的完整URL是什么？
