Thank you for your quick reply and useful information.
But, because of my company's policy, I cannot use downloaded plugin tool...
I want to do that without plugin.
The only way this can be done with JS is if the action associated with each bookmark is converted to a JS action that opens the page the bookmark is linking to and then sets the current zoom level to "Fit Page".
Thank you so much!
Does that mean JS source code is built-in pdf files？
My company and my customer are very strict about sequrity,
it is difficult to adopt the JS built-in method..
Yes, the source code will be embedded in the PDF file itself.
I'll talk our company's sequrity section and our customer about JS embedded pdf files.
Thank you for your advice!
The risks are minimal. JS in Acrobat/Reader runs in a sandbox and has very
minimal no access to the file-system...
