How to disable toolbar buttons at will?

[jaimeloci]

I have downloaded the example in http://mozilla.github.com/pdf.js/web/viewer.html and all the assets. Everything works fine. But now I'm trying to disable certain buttons to limit the functions a user has. I have tried commenting out individual buttons in the HTML code -even the div.toolbar layer- but the page doesn't load.

What should I do to accomplish that? Thanks!

Do you want to completely disable a button, or would if suffice if it's not visible?
If the latter is true, all you need to do is add hidden to the class attribute of the button's HTML tag.

Disabling completely

Looks like your issue is out-of-scope of this project. If you are removing HTML elements from viewer.js, you have to remove code that using them in the viewer.js, e.g. if 'next' button is removed, the line https://github.com/mozilla/pdf.js/blob/master/web/viewer.js#L2880 must be removed as well.

I would like to removed the button "download" from the PDF JS viewer too. Is there a way to do that instead of just included the hidden to the class attribute of the button's HTML tag?

You can remove the entire HTML element and all associated download code (in viewer.js).

@timvandermeij,
Can you tell me what lines that I would need to remove in viewer.js to remove the button element with "download" id? I'm doing this now and test the code out.

@timvandermeij,
I'm using the following PDF JS version (v1.0.907) and it seems like commenting out these lines worked. Let me know if that seems ok. I'm working with this version in the edx-platform system https://github.com/edx/edx-platform/pull/6921

Looks fine to me.

@yurydelendik I applaud, really. The prevalent willingness to work against the open web is scary.
