将 JavaScript 嵌入到现有 pdf 中
您好
我正在将 pdf 文件嵌入到我的 asp.net 页面中，如下所示
<object data="..." type="application/pdf" width="300" height="200">
</object>
问题是我已经为 pdf 创建了自己的工具栏，并且想要从工具栏图像按钮放大、缩小文档。我知道从头开始创建文档时可以将 JavaScript 嵌入到 pdf 文档中，但是如何在只有该文档路径的 html 中将 JavaScript 嵌入到 pdf 中？
Hi
I am embedding pdf file to my asp.net page like this
<object data="..." type="application/pdf" width="300" height="200">
</object>
The problem is that I have created my own toolbar for pdf, and want to zoom in, out document from my toolbar image buttons. I know that I can embed JavaScript to pdf document, when creating document from scratch, but how can I embed javascript to pdf in html having only the path of that document?

让 pdf 文档加载。文档准备好后，注入 Javascript。
但请注意，您的浏览器执行的 Javascript 与您浏览器的 Adobe reader 插件执行的 Javascript 不同。结构相似，但 DOM 完全不同。
此外，HTML 文档中的 JavaScript 无法直接访问/修改加载的 pdf 文档的 DOM。为此，您需要使用阅读器插件。很抱歉我没有以这种方式使用阅读器插件。查看 API：

并阅读本指南：

这些可能是你最好的选择，因为很少有人在 SO 上工作 pdf 的 Javascript。我之前问过一些问题但从未得到任何答复:(
Let the pdf document load. Once the document is ready, inject Javascript.
However, note that Javascript, as executed by your browser is different from the Javascript executed by the Adobe reader plugin for your browser. The structure is similar but the DOM is entirely different.
Further, Javascript in your HTML document cannot directly access/modify the DOM of the loaded pdf document. For that you will need to go through the reader plugin. I am sorry I have not used the reader plugin in this way. Take a look at the API:

and also read this guide:

These may be your best bet because very few people on SO seem to be working on Javascript for pdf. I have asked a few questions before but never got any responses :(
