I want to achieve print functionality such that user can print out the web form and use it as paper form for the same purpose. Of course I do not need all the web page header and footer to be printed, just content of a div which take most of the page. I did play around with media print css and menage print result to look almost as original page. But the I tried to print it in another browser(Chrome) and it is all messed. (before I tried Mozilla).
For the web form I user css framework Twitter Bootstrap and I had to override its css (in print media) for almost each element individually to get some normal look in the print result.
My question is is there some way (framework/plugin) to print just what you see on the page, maybe as an image or something?
Any other suggestions are welcome.
Thanks.
If you are familiar with PHP you can try the PHP class files of TCPDF or those of FPDF.
Or there is also dompdf which renders HTML to PDF, but this will include more than just the information of one div.
And for further info here is a post on Stack where users are discussing which they think is best.

With a grails app and from a local database, I'm returning some text in a xml format.
I can return it well formed in a <textarea></textarea> tag with the correct indenting (tabulation, line return,...etc.)
I want to go a bit further. In the text I'm returning, there are some <img/> tags and I'd like to replace those tag by the real images themselves.
I searched around and found no solution as of now. I understood that you can't add an image to a textarea (other then in a background), and if I choose a div tag, I won't have the indenting anymore (and therefore, harder to read)
I was wondering if using a <g:textField/> or an other tag from the grails library will do the trick. And if so, How can I append them to a page using jquery.
For example, how to append a <g:textField/> in jquery. It doesn't interpret it and I get this error
SyntaxError: missing ) after argument list [Break On This Error]...+doc).append("<input type="text" id="FTMAP_"+nb_sec+"" ...
And in my javascript file, I have
$("#FTM_"+doc).append("<g:textField id='FTMAP_"+nb_sec+"' ... />
Any possible solutions ?
EDIT
I did forget to mention that my final intentions are to be able to modify the text (tags included) and to have a nice and neat indentation so that it is the easiest possible for the end user.
You are asking a few different questions:
1. Can I use a single HTML tag to include images inside pre-formatted text.
No. You will have to parse the text and translate it into styled text yourself.
2. Is there a tag in the grails standard tags to accomplish this for me?
No.
3. How can I add grails tags from my javascript code.
Grails tags are processed on the server-side, and javascript is processed on the client. This means you cannot directly add grails tags via javascript.
There are a couple methods that can accomplish the same result, however:
You can set a javascript variable to the rendered content of a grails tag. This solution is good for data that is known at the time of the initial request.
var tagOutput = "${g.textField(/* etc */)}";
You can make an ajax request for the content to be added. Then your server-side grails code can render the tags you need. This is better for realtime data, or data that will be updated more than once on a single rendered page.
Using MVC2 I have an AJAX form which is posting to a bound model. The ActionResult is returned as Content and is inserted into an element on the page by the magic of AJAX forms. All is well.
Now I need a button that will print the returned Content. I've tried returning the result wrapped in a full HTML doc with javascript along the lines of window.print(), but of course this won't execute and even if it did I don't want the whole window.
What is the best way to have my ContentResult printed instead of updated in an element?
I've used jqPrint for this same scenario. It basically either copies the content into an iframe and calls print() on that.
I tried using jqPrint which works for the most part but it was causing problems in IE, I was printing a model dialog.
I ended up using a print style sheet:
http://www.webcredible.co.uk/user-friendly-resources/css/print-stylesheet.shtml
I basically hided all the content of the page except for my dialog, div or whatever it is you are trying to hide.
This was the solution with the most consistent results across browsers.
I currently have 2 page types in my Orchard CMS setup. One is for the front page, one for a detail page. On the front page, I have removed the body from being displayed, so that it just shows 2 HTML widgets.
Is there a way so that when someone edits this page, they don't get a body section?
A placement file might also do the trick: placement also works for the admin ui... That could enable you to make it show or not without requiring two different content types.
You can remove the Body Part from the page content type you use for the front page. This way people who edit this page won't see the editor for body content and the body won't be rendered at all.

To give you a simple use case - on my website, I display the comments posted by the facebook users. For each comment I display the facebook users photo using the fb:profile-pic tag and a fb like button.
This page renders properly and everything displays well. Now when the users want to read older comments, they click on the "More" link
Using Jquery, I pull the older comments and in the javascript build the content adding the fb:profile-pic and the fb:like tags
But these tags dont show up. Do we need to reload it or something.
Thanks for your help
First make sure the FBML is being inserted into the DOM with an inspector. If so, all you need to do is tell Facebook to convert the FBML tags to HTML tags so your browser can render it. With the Graph API you call FB.XHTML.parse http://developers.facebook.com/docs/reference/javascript/FB.XFBML.parse using the Javascript SDK. Here's an example from my code:
$('#list').append('<fb:name uid="4"></fb:name>');
FB.XFBML.parse(document.getElementById('list'));
how do I do that - like right now I
build my entire string say
comment="<div>I love
icecream<br/><fb:profile-pic
uid='xxx'></fb:profile-pic></div>"
Then I would do
$("#myswipes").html(comment); So how
would I reload.
you can use $.ajax(), say
$('a.moreComment').click(function(){
$.ajax({
url: 'some/url.php',
success : function(comment){
$("#myswipes").html(comment);
}
});
})
some/url.php should be in the server that can correctly render and return this line, <div>I love icecream<br/><fb:profile-picuid='xxx'></fb:profile-pic></div>
As the title said, I have some DOM manipulation tasks. For example, I want to:
- find all H1 element which have blue color.
- find all text which have size 12px.
- etc..
How can I do it with Rails?
Thank you.. :)
Update
I have been doing some research about extracting web page content based on this paper-> http://www.springerlink.com/index/A65708XMUR9KN9EA.pdf
The summary of the step is:
get the web url which I want to be extracted (single web page)
grab some elements from the web page based on some visual rules (Ex: grab all H1 which have blue color)
process the elements with my algorithm
save the result into my database.
-sorry for my bad english-
If what you're trying to do is manipulate HTML documents inside a rails application, you should take a look at Nokogiri.
It uses XPath to search through the document. With the following, you would find any h1 with the "blue" css class inside a document.
require 'nokogiri'
require 'open-uri'
doc = Nokogiri::HTML(open('http://www.stackoverflow.com'))
doc.xpath('//h1/a[#class="blue"]').each do |link|
puts link.content
end
After, if what you were trying to do was indeed parse the current page dom, you should take a look at JavaScript and JQuery. Rails can't do that.

To reliably sort out what color an arbitrary element on a webpage is, you would need to reverse engineer a browser (to accurately take into account stylesheets, markup hacks, broken tags, images, etc).
A far easier approach would be to embed an existing browser such as gecko into a custom application of your making.
As your spider would browse pages, it would pass them to your embedded instance of gecko where you could use getComputedStyle to pull what color an individual element happens to be.
You originally mentioned wanting to use Ruby on Rails for this project, Rails is a framework for writing presentational applications and really a bad fit for a project like this.
As a starting point, I'd recommend you check out RubyGnome, and in particular RubyGnome's Gtk::MozEmbed functionality.
