问题描述
我知道pdfium公开了javascript API().但是我找不到如何调用这些函数.在带有渲染的PDF的页面上，我可以看到一个embed标签，但是我不知道该怎么做.
I am aware that pdfium exposes a javascript API (see this question). But I can't find how to call those functions. On a page with a rendered PDF I can see an embed tag, but I don't know what to do with it.
var p = document.getElementsByTagName('embed')[0]
给我这个:
function anonymous()
__proto__: Object
<function scope>
在Chrome扩展程序的源代码中，pdf.js中包含以下功能:
And in the source code of the Chrome extension, there is this function in pdf.js:
/**
* Handle a scripting message from outside the extension (typically sent by
* PDFScriptingAPI in a page containing the extension) to interact with the
* plugin.
* @param {MessageObject} message the message to handle.
*/
handleScriptingMessage: function(message) {...}
但是它只允许'selectAll'消息.
But it only allows the 'selectAll' message.
如果有人能告诉我在哪里可以阅读更多信息或如何使用javascript与pdfium互动，我将不胜感激
I would really appreciate if anyone can tell me where can I read more info on this or how to interact with pdfium with javascript
