Single page rendering in pdf.js - javascript

Currently I am using build version from here https://mozilla.github.io/pdf.js/getting_started/#download
I would like to show only one page of pdf at screen in normal mode (not presentation mode).
Navigation between pages would be possible only through toolbar buttons. Scrolling only works for moving the displayed page displayed page.
I found something here https://github.com/mozilla/pdf.js/pull/8724 , but i don't know how to use it in my website.
Could somebody help me with that? I can't find any example of using single page mode.

Transitioning to HTML 'subcategory' page without explicitly opening another HTML file (Mobile Response)

The following image shows what I am trying to achieve.
A HTML page transitioning the view to another page, without actually having to redirect to another HTML file.
The website has a nice sliding animation when you click on a category, like on mobile when entering certain sections of the 'app'.

I am intermediate at web development, so please dumb it down when trying to explain; I'd assume this stuff is quite complex :P
Thanks.

How to print (to a printer) full DOM of a react page

I'm trying to allow a user to print a page of React (ideally just using window.print()). However, when I try to print it only shows the active portion of the page (what can be seen in the browser) and not the full page (everything including what's below the fold). I've seen that this is a problem with React apps in general and not just my app. What's the best way to print everything on the page?

What method should I use to make a Chrome toolbar?

I have this small toolbar-like html page:
Currently, a user clicks on a link and this page opens in a new tab at the size shown. The user places this at the top of their screen then opens another tab below it taking up the rest of their screen. The user mainly works out of the larger window and interacts with this "toolbar" periodically.
This setup is obviously not ideal. Especially since you cant hide the chrome frame or the address bar which make the toolbar twice the height it needs to be.
What I'd like to do is make this an actual tool bar in Chrome, something like:
I did see How to make a toolbar in Google Chrome? but I'm not sure which method would best suit my needs.
A few details:
The toolbar must remain visible anytime its turned on/opened (as I
understand it 'infobars' close themselves when not active? not 100%
on that though)
Navigating to a new page should not close the bar
Navigating to a new page should not reload / render the bar (as I understand it using content scripts would reload the bar every time the user goes to a new page,)
I guess we could use a content scripts / local storage type solution to render the bar then set it up as it was on the previous page, seems hacky though.
Am I missing a better way to do this?
Could anyone help me get started down the right path to achieve this result?
A toolbar is an extension.
use content script. The easiet way would be to download a sample from official google chrome's developper site.. and you will be able to change it the way you want.

Select of a section of a web page and output all js used there?

Is there an application that allows me to select a section of a web page, and then outputs all js used there? I've been told I can do this with Chrome Inspector, but haven't had any success so far.
Example:
On this page - http://preview.oklerthemes.com/porto/2.7.0/page-left-sidebar.html - there is a tabbed box in the sidebar. I want to easily grab all the JS/CSS needed for that box. I usually use Inspector to look at all the styles, and go and grab theme from each CSS file, but I don't know how to do this for the JS.
It's not quite clear from your question what you're asking.
Are you trying to see what JS causes writes or changes to a particular part of a web page? The easiest way would be to open the page with the element inspector, right-click a particular chunk of HTML and stick a breakpoint on modifications.
The next time a function causes any changes, the breakpoint will trigger and you'll be able to crawl up the call stack to see what the cause was.

iPad fullscreen mode - no escape found

I have a web App which has links to other web pages. When a user taps one of these links while the app is running from full screen mode the new page opens in full screen as well and so there is no means of navigating back to the web App. Has anyone found a method for escaping full screen mode on the iPad once a web App has been launched from a home screen icon ?
Try redirecting with javascript, like:
document.location='';
We actually consider this a bug, but as always there are those who would see this as a feature :)
If the page your going to is supposed to be in the app, then this solves your problem.
How can I open an external link in Safari not the app's UIWebView?
If the page is any page on the internet, then the answer is pretty much no.
Once you leave the app, there is no way back, except for the user clicking back on your app.
It is not simple to force the ipad to stay in your app. Some suggested methods:
Create your own web view in your app. If your using phone gap, or another framework, you would have to create a plug in to do this. You would then show the loaded pages on that web view, this is similar to how ads are shown & stay in the app.
Parse and replace all the links on the loaded page with custom events, and use a server to return the content, instead of loading it directly via the web.
Both are very complex, and have issues, like you cant have white lists if you let them browse outside specific domains.
