Add document loading life cycle events

[datsis]

There is need for life cycle events in case if PDFJS is used to review multiple documents.

Here is scenario:

1. User makes search and finds several documents with some keywords
2. When user click on document PDFJS is loaded document with open(url) function
3. When document is loaded and rendered it is necessary to highlight keywords

For now there is no way how to catch a moment when document has been rendered.

There is no exact moment "when document has been rendered". The pages are rendered when they become visible. Only one page documents are "fully" rendered.

To find keywords in the document, the find UI can be used, which will index PDF page by extracting the text content page-by-page. Do you mean to add event to signal when keyword is found or not found?

Hi, Yury!

Actually I try to use such code sample to highlight keywords:
PDFFindBar.findField.value = keywords;
PDFFindBar.dispatchEvent('')

I try to call it after each call of PDFView.open('url', 0) but it does not work because at the moment when PDFFindBar is called the document is not rendered yet

The perfect way would be to call something like that:
PDFView.open('url',..., {search: 'some-keywords'}) for each showing document

On the other hand more flexible way is to subscribe for some events which can looks in this way:
PDFView.addListener('already-can-highlight-something', function(){
PDFFindBar.findField.value = 'some-keywords';
PDFFindBar.dispatchEvent('')
}

There's the documentinit event, which signals that the document is ready for user-interaction; this issue can probably be closed now.
