Viewer options #66

Closed bartonwelt closed 4 years ago

bartonwelt commented 4 years ago

Is there a way to pass viewer options with the helper as found here: https://github.com/mozilla/pdf.js/wiki/Viewer-options

Ex: <%= pdfjs_viewer pdf_url: "/sample.pdf", style: :full, pagemode: :bookmarks %>

or: <%= pdfjs_viewer pdf_url: "/sample.pdf?pagemode=bookmarks", style: :full, pagemode: :bookmarks %>

I figured this out with JavaScript. Trying to append the query parameters after the file URL resulted in the string being encoded so I had to add the params dynamically. There's probably a more clever way to do it in Rails but I didn't have the time.

.js

$(document).ready(function() {
  let iframe = $(".pdf-js-viewer iframe");
  iframe.attr("src", iframe.attr("src") + "#pagemode=bookmarks");
});

.html.erb

<div class="pdf-js-viewer">
    <iframe src="<%= pdfjs.full_path(file: "#{file_path}") %>" title="webviewer" frameborder="0"></iframe>
</div>
