PHPExcel loading message during file generation - javascript

My page has a link that downloads an excel file with PHPExcel. This file is very large and it spends a lot of time. I want to show a loader dialog, or disable the link during the file is generating.
I tried to show a div with $(document).ready() but not working. It seems that the download not reload the page.

Download a pdf (not open in tab) in Javascript

I have a landing page on which there is a form which is filled by user and then it goes to a thank you page (which is another page). On thank you page I simply want to prompt the user for saving a pdf as the thank you page loads. Please note I want the file to be saved/downloaded and not opened on the same tab or another tab in the browser. I have tried multiple solutions but they all seem to open the pdf in the browser itself and not download it. Some of the methods I have tried are meta tag download, page redirect download, iframe download but they all open the pdf in browser itself and not download it. I just want a simple solution for downloading the file and not opening it in the browser. Also the pdf should download automatically without clicking any link or button.
The document.ready event of the thank you page should trigger a local script that runs a server script to download the PDF. Be sure to set the headers as described above. If you try to link directly to the PDF, it'll try to load in the browser.
Alternatively, you could create the PDF in a directory that is already set to only download files by setting the .htaccess file for that directory.

How to embed in html page a PDF generated on the fly with jsPDF

I had project with java that created the pdf from the back-end and saved that pdf for while so the user could download that file within a frame of time, so embedding or sending that file was easy because it have a physical copy in the server, now for this project the pdf is generated with the dynamic html content the user chooses with jsPDF, but this file the user only can save it directly to his/her computer.
There is a way to show this pdf generated on the fly embeded in a html page like a modal/div or a tooltip (for a thumbnail preview)?
It would be better if there is mobile friendly solution.
Since mobiles have some issues with iframe i'm not considering that as an option.

Image button - print a document from my webpage

I have a website, but I need a button which I want to print a specific .pdf file from my webpage database.
As an example, this site
has a print button, which gives you option to print some pdf files
Any idea how can I do that?
I've tried this one, but it's not working:
<a href="../Documents/ScrittoGraffito/Scritto_Customers/Nicolaides_Optical/Nicolaides_webpage/Shop1_Banner.pdf"
onclick="window.print()"/><p class="test">link</p></a>
That code will tell the browser to open the print dialog for the current page.
If you want to force the browser to print the linked pdf then that is not possible, as it will be completely controlled by the application or plugin that handles pdf documents.
EDIT;
Apparently it is possible, but you have to make use of a pdf toolkit.

Javascript to Load and Save Files Temporarily

I am working on a thing where I have an iframe. I want to load a static javascript file to this iframe every time user clicks on a button. The javascript file is located at the server and because this is the static file so I would like it to be downloaded to the client once and every time user clicks on the button it just loads this file into iframe without calling server.
I know AJAX can be used to download this file contents and how to add script tag to the iframe but I am not sure where should I temporarily save the contents and then put the contents back into a file to put that file as script tag into iframe.
You can consider this fiddle.
Have you considered just dumping the data into a cookie?

iFrame file upload with IE produces download dialogue

I'm developing a custom module for Drupal dealing with Document Management. At this point, the module loads, you can upload files (via a hidden iframe and some ajax requests), browse directories and set various levels of permissions. And everything works perfectly in Firefox.
Issue:
In IE however, I run into an issue. For some reason when I upload a file the save file dialogue pops up and asks me to download the file I just uploaded. It looks like it's asking me to download it from the web-servers tmp location however, as that seems to be the file-name and such. However, if I hit cancel and refresh the page I can see that the file I uploaded did actually get uploaded to the server.
Here is how the upload process works. Click the upload button. The upload button is the standard file input form element hidden and placed over a styled version of the button. Clicking on this causes the "Choose a file" dialogue to open.
Select a file and click "Open". A modal dialogue pops up asking you for some further information about the file. The modal is part of the same form element but remains invisible until you click Upload button
Clicking save in the modal causes the file to be uploaded. The "action" attribute on the form is pointed to a page and the target is the iframe.
The iFrame is polled a few times every second to see if it's contents have changed. When the file is uploaded a "success" message appears in the iframe. Since it belongs to the same domain, I scrape the content within the iframe.
Once the iFrame says that the file has been uploaded, I use some JS to update the application with the name of the file
Since I can't use Firebug in IE, I have to stick to utilizing Microsofts Web Developer Toolbar, which makes it very hard to figure out if the bolded step is actually occuring. It seems like it should, since the file IS being uploaded. It is just getting interrupted by that file download dialogue.
Since no one seems to have an answer, I'll post the fix I found. I doubt it's perfect, but it's the best solution I could come up with.
It turned out to be an issue with the polling as suspected. The fix ended up being instead of outputting json to the iFrame, just output some JavaScript that calls a function that updates the main window. That simple.
