推荐答案

当记住客户端上的页面是服务器最初产生的结果时，这是一个有点奇怪的想法.

抛开这些，您可以遍历整个页面(文档)，并将所有元素(包括属性值)放入一个巨大的字符串值中，然后将其发送回服务器.您将能够在浏览器组件服务器端重新创建网页的当前状态.除了浏览器兼容性之外，这还可以让您了解客户端当时正在查看的内容.

祝你好运！

That is a somewhat strange idea when keeping in mind that the page on the client is the result of what the server produced in the first place.

Putting that aside you could traverse the complete page (document) and put all elements (including the attribute values) into one giant string value and send it back to the server. You would be able to recreate the current state of the webpage in a browser component server side. Browser compatibility aside this would give you a representation of what the client is viewing at that moment.

Good luck!
