I downloaded the zip file containing the sample HTML and scripts for the book from this web page http://www.larryullman.com/books/modern-javascript-develop-and-design/ decompressed it and saved it as a set of folders in my Dropbox account.
What I wanted to be able to do was to use the Dropbox app on my iPad to select a particular HTML file and see how it rendered on the iPad, but it didn't seem to work (I didn't get an error message; it just didn't display the rendered page).
I realize that this may be more of a question related to the Dropbox app on the iPad than it is about HTML or JavaScript, but Dropbox claims, in their help documentation, that they do support files of type HTML in their iPad Dropbox app.
So, I am looking for any suggestions as to how I could directly view these web pages (powered by the associated JavaScript) on my iPad.
There is an indirect way to view those files, and that is, via the Dropbox app on my Mac, I can "copy public link" and email that link to myself on the iPad (for example https://dl.dropboxusercontent.com/u/1124048/Sandbox/javaScriptLearn/modern_javascript_scripts/ch07/today.html ), but I am seeking a more direct approach.
