I was trying to save a URL to disk by right clicking on the page but the saved page does not have the text I see in the browser. I am using firefox. This is a pretty regular page rendered with text obtained by a JS call after the page is loaded.
Here is the URL - www.chilis.com/EN/Pages/menu.aspx
When I open it in the browser I see some menu items but when I save the page to disk and then open it I don't see the menu items. I understand that the CSS, JS and images are there as links and so they will not be there in the saved file. But I expect the text to be there. Why the discrepancy?
The likely cause are the browser security settings. Since you are serving the file from disk, many requests will be cross-domain. Try serving the file from your own web-server and see what happens. Also, have a look at the console when accessing the page from disk. The error messages will help.
The menu items are there - you cannot see the text because it is out of alignment because of css text-indent property. the shown texts on their website are images set as css background (these can of course not be found/loaded by url(givenpath)):

I am trying to display PDF file on the web without download option and copy option.
Then I found this https://books.google.co.in/books?id=kwBvDwAAQBAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
Can you tell me how can I achieve this on my website?
What mplungjan said in his comment is correct. Anything that is put on the web can be copied one way or another. It appears that the google site you linked to is just showing an image of each page (see https://books.google.co.in/books/content?id=kwBvDwAAQBAJ&pg=PP1&img=1&zoom=3&hl=en&sig=ACfU3U0s8V3HjcApLeNwIGStMQlzZFaotA) with transparent pixels over each image to make it so you can't right-click to save the image. But it's easy to see what they're doing by viewing the source in the inspector.
If you don't want your users to be able to download the entire file, you could break it up into multiple small files (or images, like google is doing in your link) that would make it a little harder for them to get the files. But you can't really stop them from downloading anything.
My issue is that I have to deploy a local server (without internet), so I cannot use Google Doc Viewer in this case. All I want is to restrict the user from download or printing the document. I have tried hiding or removing the toolbar in JS but it is not working out.
You may be able to disable the toolbar somehow, but that isn't good enough to keep users from downloading or printing it anyway, and nothing you can do will be. If a person can see something, they can copy it, no matter what you try to do to stop them (and all trying will do is inconvenience legitimate users). Previous similar questions:

Although those talk about images, the exact same reasoning applies to PDFs.
I have made a small web page in which I have some modal windows (jquery.simplemodal). When those windows are showed they should display two pdf files ( downloaded from server ).
<div id="modal1"> - hiden modal window
<embed src="/FileDownload?id=100" width="100%" height="600px">
<embed src="/FileDownload?id=150" width="100%" height="600px">
</div>
<table>
<tr>
<td>
Modal Window 1
</td>
</tr>
</tale>
The problem I have is that when the page is loaded also is downloading all files from server.
From HTML point of view I had read that nothing is possible to do to avoid this.
Can you please tell me if is posible to do that with Javascript ( for example updating src's embed element when the modal window is first displayed )?
On http://stackoverflow.com I have found some topics about changing the properties of an element but nothing is working on me.

Can i open a modal window from file A and displaying file B on the modal window?
Thank you!
P.S. This is an Intranet application. I want just to avoid downloading 20-40 files (a few MB each ) every time the page is open. The other solution I am thinking is to use a Java applet but I think this would complicate this small project.
Using jQuery. I believe this is what you want to do: only load embed files if you click on the link which pops up the modal?
$("a").click( function (e) {
e.preventDefault();
$("#modal1").append("<embed id='100' src='/FileDownload?id=100' width='100%' height='600px'/><embed id='150' src='/FileDownload?id=100' width='100%' height='600px'/>");
$("#modal1").show();
});
And the Fiddle
The nature of Web browsers is to download files to a cache so that upon the next visit, or during page changes, display times are greatly reduced. As a web developer there is nothing you can do to prevent this. The user can turn this feature off in his own browser if he desires to keep his cache clean, but you and your site cannot. There are ways to impede a viewer from intentionally downloading an image or file such as disabling right clicks over an image, but there are ways for a savvy user to get around these methods as well.
PDF files especially need to be downloaded to speed up viewing. If this is turned off, the user experience will be so slow you will drive people away from your site.
Even if its impossible to completely protect your files, there are a few ways to make it harder to download your original PDF document, we have a few PHP scripts that may help you that you can find inside our desktop publisher (available in GPL and commercial).
Its free to download and you can grab the scripts even if you don't use the rest of the product. If you download it and as you publish your document you can expand advanced settings and tick "sign and obfuscate" and you should get the scripts necessary to protect your files.

The client's website has product listings. The prices for the product are pulled dynamically in through an iFrame at the bottom of the page. There is Javascript on the page that automatically resizes this iFrame to the correct height based upon how big the iFrame content is, once it's loaded.
The client is reporting that when printing the page, they cannot see anything from the iFrame where the prices should be - apparently it is not printing in IE, just the main page itself.
I am on a Mac and so can't test in IE, so I'm having a hard time experimenting with this.
Can anyone clarify the expected behaviour in this situation? Is it possible to get IE to print both page and included iFrames by default, and if so, how would I go about doing this? I can only find examples for printing a specific frame from a parent window.
Thanks!
The expected behaviour should be what you're experiencing in other browsers. If the page is printed, the iframe should be printed along with it. It would be difficult to imagine that everyone else got it wrong and IE got it correct in this instance.
Below is a bit of speculation on what the issue might be, but without knowing more/seeing code it's difficult to know the specifics:
This issue could be due to some css that you may have on your page. I've read of similar iframe printing issues where the visibility was set to hidden initially resulting in the iframe not printing correctly. To get around this specific case the user had to set the width and height to 0px. Without knowing more about your site, I can not correctly predict that this is happening.
Another issue may by your dynamic resizing based on the contents of the iframe. A simple test would be to comment that section out and set a generic width and height on the iframe to see if the printing issue still occurs. Perhaps those dynamic styles are not being carried over to the print stylesheet and are not getting applied (therefore not appearing at all).
As a quick suggestion, look into css media types:
print
Intended for paged material and for documents viewed on screen in
print preview mode. Please consult the section on paged media for
information about formatting issues that are specific to paged media.

This was an interesting point, so I did a test using IE8 (on a server, not locally).
I printed in IE8 a web page that included an iframe of something that I built. And it printed some of the contents the first time (the other contents showed up black). The second time I printed, the iframe contents were all black.
However, in my example, the contents in the iframe are changing constantly (images and text that fade in and out) and the css background behind it is black.
This test has the contents of the iFrame on a different host server than the contents of the main page. But to my knowledge, there is a cross-domain policy file working here.
Cross-domain policy issues were my first guess, but it's entirely possible there is some issue with how internet explorer renders the screenshot when it sends it to the printer.
If you are using Javascript, then why not try window.print() function along with print media CSS.
I can't explain why IE isn't working, but maybe you can fix the problem by adding this part of code into the parent page, in order to force each iframe to be refresh :
$(document).ready(function() {
if($.browser.msie) {//Only for IE
$('iframe').each(function() {
$(this).attr('src', $(this).attr('src'));
});
}
});
To get the browser, i use this method.
And i don't use contentDocument.location.reload(true); method to be sure the iframe to be refresh. See SO topic.

I have a PDF embedded in a web page using the following code:
<object id="pdfviewer" data='test_full.pdf#page=1&toolbar=0&statusbar=0&messages=0&navpanes=0'
type='application/pdf'
width='500px'
height='350px'>
The PDF itself is set to open in full screen mode which shows no controls. The user can advance the slides by clicking on the view.
What I'd like to have is some way to trigger that click so that I can advance 2 similar PDF:s side-by-side (one for the actual slideshow and one for the speaker notes). Is this possible to do in javascript and/or jQuery? I have tried using the click()-method but it doesn't get through to the embedded PDF.
Update: Can't find any info on it, so I guess I'm out of luck and have to try a workaround. Am currently juggling 3 embeds of the same pdf (current page, next page and previous page), hiding and showing them and loading more pages as the user clicks around.
I doubt it. Allowing web page scripts to pass input events to the PDF viewer could be a security risk (since the viewer generally has access to system file dialogues via things like Save As).
