[dba-Tech] Great JS PDF Viewer...

[Jim Lawrence]

Hi Shamil:

First thing to note is that the PDF display code is just a function for a larger application. Pay attention to the universal variable that hold and are assembled the entire URL. Check how the  "download_manager.js" assembles the entire PDF URL. Comment out the default assignments within the Viewer code and assign them from the application calling this code. In other words assign the Global variables within the caller routines.

Second, you could do something as simple as pass the Viewer routine, the URL via parameters. Its not classy but it is simple and it works. 

Then there is HTML5's sessionStorage:

 Hi Jim --

Thank you! I somehow missed to find this default .pdf file assignment.

Now, here are two challenges:

- 1. load .pdf from a url/fileName passed to the viewer.html in url parameter, e.g:

    {custom site pdf viewer url}/viewer.html?pdfFile={myTestPdfFileUrl}

- 2. load .pdf via AJAX call(s) from a web service, which attributes are passed to the viewer.html would in url parameters, e.g:

    {custom site pdf viewer url}/viewer.html?service={webServiceEndPointl}&pdfFileCode={guid}&...

Anybody?

Thank you.

Note: The PDF file is in that root directory and is called "compressed.tracemonkey-pldi-09.pdf" The file name is assigned to the global variable "URL", in the JavaScript file named "viewer.js" (loaded and called from the "viewer.html" file), on line 30 but it can be assigned anywhere within the html application or via a config file. See the JavaScript function file, "download_manager.js" which assembles the PDF url, for the actual downloading code.
