Question

扩展目的：保存用户手动输入的易趣卖家用户名。当我们对产品有持续的问题时（即发送有缺陷的，错误的商品，打开退货的麻烦等），我们会添加eBay卖家。
当产品页面上有eBay用户名（存储在扩展名中）时，页面的背景颜色会闪烁红色几次，表示您不应该从该卖家处购买。

Type in the username. Click "Set". The username will then be added to the "blacklist". All stored usernames are visible above the text entry box.

问题：如果您在与扩展程序交互之前检查弹出窗口，则扩展程序将仅保存用户名。这些是我暂时遵循的步骤......
1.右键单击弹出窗口
2.单击“检查弹出窗口”
3.输入用户名
4.单击“设置”

我处于停滞状态。任何帮助表示赞赏。

Answer 1

我已在浏览器中测试了您的代码，并且正在设置用户文本而不检查代码。

您可以再次验证并检查您是否遗漏了任何内容，或者您的控制台是否有任何错误。我最终看起来很不错

Chrome扩展程序仅在检查弹出窗口时有效
