A have a project on angularjs and I need to create and download a document for print(no needed to save it on server). It can be .docx, but .pdf is preferable(so simple user won't able to change file). So, I know that there is a framework called PHPWord, but I don't like php at all. And there is another framework called docx.js(but it jquery required).
There is one more problem that I need to add values of variables to the docx template(which located on server, so admin can change it, of course he won't touch variables in this file) and then download fulfilled pdf document. It is not necessary to use docx template, nevertheless this variant is preferable.
Can you give me some recommendation in which way I need to look? Maybe you know some good framework based on native JS?
I haven't personally used this, but it looks like a contender.
It runs atop Node, so you can leverage your JavaScript skills.

I am working on a project where I want to scrape out data from a website whenever the value of the range slider is changed by the user and compare it with the actual data.
The tasks are:
Scrape the actual data(initial value)
2.Scrape out the base data(the value changed by the user)
I am supposed to extract the base data for each change in value done by the user and compare it with the actual data and store it in local directory
(CONDITION: Must be done only using JavaScript)
The slider is present within an iframe.
Can someone please suggest any approach/packages for doing this?
There are different ways to do scraping in javascript:
Regular Expressions: The hard way
Cheerio: Core JQuery for traversing the DOM
JSDOM: The DOM for Node
Puppeteer: The headless browser
Nightmare: An alternative to Puppeteer

I've been playing with this rather spiffing online embeddable image editor from Aviary, and it does exactly what I need it to, namely:
embeddable in my site as HTML/JS
reasonably priced
only basic, fun features
completely idiot proof so even the most ham-fisted can thrash their way to something passable; or to put it another way, I don't want/need a traditional image editing interface like Photoshop - the way that Aviary have done it is pretty much spot on for my needs
However, in the documentation, they indicate that this is only suitable for web-resolution images, while I need to allow users to edit hi-res images as they will eventually be sent to a printer.
Does anyone know of anything comparable to this Aviary editor that can work with hi-res images?
Have you tried pixlr? As far as I'm aware, that editor is hi-res-capable.
In answer to my own question, it turns out that if you pay for the Enterprise version of the software, then full resolution is supported.

I have an idea for a CMS enhancement, to extract text information from images (for example, scanned documents), and want to know if there is already anything out there to help me along?
Basically, I want to know if there is an existing OCR script written in JavaScript that can extract sentences/words from an image (using canvas, for example).
I know there are some scripts that do relatively small tasks such as captcha-cracking, but I haven't yet come across a script for extracting full sentences.
Is there such a thing, or would I need to write it from scratch?
Antimatter15's Ocrad.js is a possibility
Take a look at https://github.com/selead/node-ocr. It's a CoffeeScript libray to access ABBYY Cloud OCR SDK service.
There is a tesseract module for node.js available on github.

In Django 1.3, django.contrib.staticfiles provides a nice "blessed" solution to managing static files, like a site's CSS, Javascript, and images.
However, I don't see an obvious way to integrate arbitrary static file preprocessors (concat/minify CSS/JS, spritesheet autogen a la SmartSprite, etc.) with the staticfiles app.
Do any projects/snippets/solutions exist for this that will integrate well with django.contrib.staticfiles?
django-compressor have support for this, asking you to add 'compressor.finders.CompressorFinder' to the STATICFILES_FINDERS setting. I guess you can use or spy their code to see what they have done to achieve this.
django-compressor is definitely my preferred option because of how easy it is to just wrap blocks of css and js includes and have them compressed, however it does not do sprite sheets.
So you could either build in an additional processor to django-compressor using spritesticker or use django-media-bundler instead which does both but takes more effort to setup.

Does anyone know about a tutorial that lets you to create something like pageflakes.com for your website? In jquery perhaps?
The creator of PageFlakes, Omar al Zabir, has created an open-source web portal called DropThings. Can't get any more similiar to PageFlakes than that!
You can use the UI library from jQuery where you'll find the draggable elements with grid. Besides that you only need to set and read some cookies that determine the position of each of the boxes.
Let's say your layout has 4 <div>s. Just save each id and position in a cookie (from javascript or by performing an AJAX request to a php/asp page).
Displaying the page is also pretty easy, you have to have 2 possibilities: when the user has a cookie defined, or else (this would be the default). If the user has a cookie defined, read it and position the <div>s like the cookie says, it shouldn't be too hard to do this.
This article on CodeProject has an excellent tutorial on how to build almost exactly what you're after, except that it uses ASP.Net Ajax. You would easily be able to substitute that with jQuery though.
.nettuts has an example all done in jquery and jquery ui. Here's the link:
http://net.tutsplus.com/tutorials/javascript-ajax/inettuts/
Goes through it all in very nice detail too. It won't be a direct copy of pageflakes, that's an exercise left for the reader but it does show exactly how to start.
HTH!
Check out ExtJS's Panels. They're what's used to build this pageflakes look-alike:
