TYPO3: pop-up on every page

I would like to add a pop-up with a custom message that appears on every page.
I use bootstrap so I could use a modal ?
What's the easiest option ? I couldn't find an extension for it

Therefore you don't need an extension but a HTML markup (realized in your (Fluid?-)templates) and some individual CSS and javascript.
Be sure your information is on every page as an ordinary content (you will find enough answers to this in the web) with an unique identification (e.g. div#modalId), then make sure that this content is changed visibly into a modal, either with pure CSS, or with javascript.

Best way to display various information in bootstrap or other jquery dialog box

I have 4 images, each image has its own information and images. Not a lot, but I need it to be displayed in a pop up box. I have decided to use Bootstrap as it's responsive and quite reliable for these thing.
My question is is there any way around copy and pasting the same information, for instance, I have 10 lines of the same code just to show the modal box i.e.
$("#smiley").click(function () {
$('#myModal').modal('show');
});
and 200 of information etc.
Here's example http://jsfiddle.net/jjehfiuehf/0ck8y5jx/
You click image and the modal box appears.
The dialog box doesn't seem to appear for some reason
Is it ok to have a full html page full of information or is there a way to condense it somehow??

Dialog box does not appear because of Jquery version you should use 2.1.3 on left side you have on jfiddle Frameworks & Extensions, framework can be changed.
2.it is OK to have all information in html, and if you do not want all information in html, you should use server side scripting, PHP or else.

You could use one modal and load the information dynamically from a PHP script using AJAX.
Put all of your images, 200 (whatever) of information, etc. into a PHP script - perhaps in an array.
In your HTML, include an ID or data-attribute that corresponds with the key in the array. Each one is unique.
Create a jQuery script that parses the ID or data-attribute, and then calls the PHP script via jQuery's .get() method, which then loads the content into the modal body and displays it.
You could also store all of these as separate HTML documents instead of putting them into PHP, and load each file accordingly...
Also, there's Varying modal content based on trigger button - which may be more inline to what you need
From the Bootstrap docs:
Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use event.relatedTarget and HTML data-* attributes (possibly via jQuery) to vary the contents of the modal depending on which button was clicked.

How to Print a Hidden Page TWICE in a PDF using LiveCycle Designer

I'm developing forms with LiveCycle Designer and my colleague at work asked me this question.
I only could think of making a page visible in the prePrint - Event and hide it in the postPrint - Event. But I don't know how to multiply it during runtime.
Does anyone know of cool ways to do this with Javascript (Adobe JS)?

It depend on how you print- by using a button build in the PDF and print call in the onClick event or "normal" print.
If you use normal print you can affect the PDF by prePrint and postPrint events, like changing presence of the hidden objects. The easiest way would be here to duplicate the hidden page and make both pages visible in the prePrint event and hide them in the postPrint event.
Second way:
Set you hidden page text flow.
Select every object on hidden page and enclose with a subform.
In the binding option of the subform "Min count" under "Repeat Subform for Each Data Item" set to 1.
In the rpePrint after you set visibility of the page to true add "PageName.SubformName.instanceManager.addInstance(1)"
In the postPrint event remove add "PageName.SubformName.instanceManager.removeInstance(0)" and set visibility of the page to false.
But if you have a button inside the PDF-Document then you have could call print function. You will have to call the function 2 times with different page-range depending on where the hidden page is

Attache script to the visualforce parent page

I have added my visualforce page to Account page and found that I can set only fixed height. I wrote javascript solution for auto height. First part I added to the parentAccount page by adding new button with {!REQUIRESCRIPT("my_scipt_here")}, second part I added to visualforce page.
s it possible to add javascipt to the "parent" Account page without adding Custom Button?

I'm not aware of any way to run javascript on a page other than by using a button (or maybe a link as a field), though it'd be good to know if there is one but I highly doubt it would be available, or if it is, supported.
Would overriding the Account view page with a full visualforce page be an option where you use an <apex:detail> tag to get the standard fields etc.?

Remember that Visualforce components on page layouts occur as iframes. If the domains match up, which may or may not be the case - you could inject JavaScript from the iframe to the parent.
This may give more details:
Inject javascript function into parent window from iframe

How to display a form in any site's pages using a bookmarklet (like Note in Google Reader)?

In Google Reader, you can use a bookmarklet to "note" a page you're visiting. When you press the bookmarklet, a little Google form is displayed on top of the current page. In the form you can enter a description, etc. When you press Submit, the form submits itself without leaving the page, and then the form disappears. All in all, a very smooth experience.
I obviously tried to take a look at how it's done, but the most interesting parts are minified and unreadable. So...
Any ideas on how to implement something like this (on the browser side)? What issues are there? Existing blog posts describing this?

Aupajo has it right. I will, however, point you towards a bookmarklet framework I worked up for our site (www.iminta.com).
The bookmarklet itself reads as follows:
javascript:void((function(){
var e=document.createElement('script');
e.setAttribute('type','text/javascript');
e.setAttribute('src','http://www.iminta.com/javascripts/new_bookmarklet.js?noCache='+new%20Date().getTime());
document.body.appendChild(e)
})())
This just injects a new script into the document that includes this file:
http://www.iminta.com/javascripts/new_bookmarklet.js
It's important to note that the bookmarklet creates an iframe, positions it, and adds events to the document to allow the user to do things like hit escape (to close the window) or to scroll (so it stays visible). It also hides elements that don't play well with z-positioning (flash, for example). Finally, it facilitates communicating across to the javascript that is running within the iframe. In this way, you can have a close button in the iframe that tells the parent document to remove the iframe. This kind of cross-domain stuff is a bit hacky, but it's the only way (I've seen) to do it.
Not for the feint of heart; if you're not good at JavaScript, prepare to struggle.

At it's very basic level it will be using createElement to create the elements to insert into the page and appendChild or insertBefore to insert them into the page.

You can use a simple bookmarklet to add a <script> tag which loads an external JavaScript file that can push the necessary elements to the DOM and present a modal window to the user. The form is submitted via an AJAX request, it's processed server-side, and returns with success or a list of errors the user needs to correct.
So the bookmarklet would look like:
javascript:code-to-add-script-tag-and-init-the-script;
The external script would include:
The ability to add an element to the DOM
The ability to update innerHTML of that element to be the markup you want to display for the user
Handling for the AJAX form processing
The window effect can be achieved with CSS positioning.
As for one complete resource for this specific task, you'd be pretty lucky to find anything. But have a look at the smaller, individual parts and you'll find plenty of resources. Have a look around for information on modal windows, adding elements to the DOM, and AJAX processing.
