html 对象标签的滚动位置
我正在开发一个通过对象标签
I am working on a project that pulls in a pdf document via the object tag <object data="the-url-to-the-document" class="ppa_document" type="application/pdf"></object> and I want to find out if the user has scrolled to the bottom of that embedded document to then enable the "i agree" checkbox. I tried it will the jQuery .scroll() function but that didn't work. Any suggestions? Considering Adobe Acrobat is a totally different interface, it may not be possible. On the other hand, it does become part of the DOM, so maybe it is possible!?

对于大多数 DOM 元素，您可以使用scrollTop 属性。例如：
然而，
For most DOM elements you could use the scrollTop property. For example:
However, what happens inside of the <object> tag is a different story... In case of PDF files, Acrobat Reader is handling the scroll bars and I do not believe there is an API to get the scroll bar position. However, please correct me if I am wrong, as I'd love to know myself if there is such a thing.
