Hi,
I am trying to page jump via link annotations.
The link annotations were assigned the following script.
"this.pageNum=10"
I implement PDFReaderListener and call PDFPerformAnnot() in the OnAnnotClicked method.
I expected to get page number or script string from uri parameter in OnOpenURI, but it was null.
Is there any way to get the page number from link annotation?
Thanks.

Hi,

the OnOpenURI method return null beacuse it handles external links like URL, not page jump links.

To handle page jump links you can use
m_view.vGotoPage(dest);
like in the demo project

You can also check in the demo project the PDFPerformAnnot method in PDFReader class.

Thanks for the reply.

It's a pity not support javascript.
I would like to see this in future release.

I'll change the link script to the external link in order to get page number from annotation.
It's not working as a page jump in general pdf readers, but my pdf file is only used in my application.

Thnak you.

I really appreciate your prompt measures.
I check new release. The new interface OnOpenJS and GetJS works nice.

I have a one more request.
May I ask you to release this feature to the iOS SDK?
We are developing also for iOS application...

Thank you.
