刷新广告位
您可使用 Google 发布商代码 (GPT) 库的刷新功能来动态重新加载广告，而无需刷新整个网页的内容。
为实现此功能，您将需要生成一个 GPT 代码，并对其进行些许修改。下面这个实现示例中有两个广告位以及用于使用新广告刷新广告位的相应按钮。

This sample implementation features two ad slots and\ncorresponding buttons to refresh the slots with new ads.\n\nSample implementation\n---------------------\n\n[View demo](https://googleads.github.io/google-publisher-tag-samples/refresh/js/demo.html) \n\n### JavaScript\n\nLoading...\n----------\n\nLoading...\n----------\n\n[Improve this sample](https://github.com/googleads/google-publisher-tag-samples/tree/main/dist/refresh/js) [Report an issue](https://github.com/googleads/google-publisher-tag-samples/issues/new?labels=documentation&template=sample-feedback.md&title=Sample+feedback%3A+refresh/js)\n\n### TypeScript\n\nLoading...\n----------\n\nLoading...\n----------\n\n[Improve this sample](https://github.com/googleads/google-publisher-tag-samples/tree/main/dist/refresh/ts) [Report an issue](https://github.com/googleads/google-publisher-tag-samples/issues/new?labels=documentation&template=sample-feedback.md&title=Sample+feedback%3A+refresh/ts)"]]
