I'm using a Crawler4j and Jsoup to crawl a website and it works fine for the HTML text, but there are some important contents, which default values are hard coded in CSS and then dynamically set with JavaScript.
For example, I have the
and I need the width value, which in CSS is hard coded as 10px, but modified in JavaScript to, let's say, 5px.
Is there a way to get this value without using another crawler? Or a simple alternative?
I have already quite a lot of code, so I don't want to rewrite everything if there is a possibility to do that with the Crawler4j.
I hope my question is clear enough and thank you in advance for your help!
This is not possible with crawler4j nor with jsoup. They both handle only static HTML content.
There are several open issues related dynamic JavaScript execution on the official GitHub Repository: #49, #197 and #220.
To achieve your objectives, you would need to build a stack based on Selenium, CasperJS and/or PhantomJS, which could then be used for advanced crawling including JavaScript execution.
I've started using new tool,GI, for automated testing, and ill need to make javascript for testing the website's links, if they are clickable through, and there are no 404/500 pages on website. Ideally script should just include javascript code and be as simple as possible. Thank you in advance for help!
I've created a page with CSS. Now I must change from my editor to my browser and refresh the full page, just to have a look at every little change. But I don't want to refresh the page, because I have some animations.
So is there anything which I can use that my site updates automatically after a CSS update?
Maybe with JavaScript, jQuery, Ajax or something?
Here you are: http://cssrefresh.frebsite.nl/
CSSrefresh is a small, unobstructive javascript file that monitors the CSS-files included in your webpage. As soon as you save a CSS-file, the changes are directly implemented, without having to refresh your browser.
Just insert the javascript file and it works!
But note: It only works when you have the files on a server!
Edit: LiveStyle
If you develop with Sublime Text and Google Chrome or Apple Safari, then you should use Emmet LiveStyle. This is a more powerful Live CSS-Reloader.
Now I use it instead of CSS Refresh.

With jQuery you can create a function that reloads external stylesheets.
/**
* Forces a reload of all stylesheets by appending a unique query string
* to each stylesheet URL.
*/
function reloadStylesheets() {
var queryString = '?reload=' + new Date().getTime();
$('link[rel="stylesheet"]').each(function () {
this.href = this.href.replace(/\?.*|$/, queryString);
});
}
Have a look at http://livereload.com/.
It works as a browser plugin for OS X and windows. I like it because I do not have to embed additional javascript which I could accidentally commit in my versioning control.
I find browser plugins/extensions to be the easiest solution. They don't require any code changes to your individual sites. And they can be used for any site on the web — which is useful if I modify something in-memory real quick to hide a toolbar or fix a bug temporarily; once finished mucking with it, I can press a key and all the CSS is back to normal.
Once installed, (most) CSS reloaded plugins/extensions don't reload the CSS automatically. But usually work with something as simple as a toolbar button, a context menu item, and/or a simple key press to reload the CSS. I find this method is less error prone anyway, and is much less complicated then some of the automated solutions out there.
Some examples (feel free to suggest some others):
Chrome:
tin.cr (includes automatic reload, and can persist in-browser changes to source files)
CSS Refresh
Firefox:
CSS Reloaded
CSS Refresh
Here is my little Project. Please give it a try

Yes you can manipulate the CSS via jQuery:
$(".classToBeReplaced").switchClass( "classToBeReplaced", "newClass", 1000 );
You could also use the toggleClass method.

Firebug for FireFox.
It's a plugin in an attached/separate window. Changes to HTML/CSS appear instantly, elements are highlighted.
Advantage over JS hacks is that you can't copy this accidentally to your production instance.
You are looking for Live Reload:
It's available as a browser extension and easy to implement
http://livereload.com/
The new open-source code editor, brackets, has a Live Development feature where you can edit CSS in the editor and it will immediately be reflected in the chrome browser. It currently only works for CSS editing, but HTML editing is coming soon!
Firebug for Firefox is my prefered method:
https://addons.mozilla.org/de/firefox/addon/firebug/
You can edit HTML and CSS on the fly, quickly deactivate CSS rules (without deleting them), add or remove HTML and so on. If you wan't to tweak your design this is your choice. You can even save changes to a local copy, but I hardly ever use that feature.
If you are using Firefox then you can install Web Developer Toolbar 1.2.2 from Add-on of Firefox which has option of Reload Linked Stylesheets.
Try using CSS Brush, a chrome plugin for creating CSS live. You needn't have to write all CSS in a text editor, come back to browser and reload it, rather write the CSS live as if you were doing it in a text editor. You will have more features than a text editor here like context-sensitive-menu, use duplicate properties, select complete CSS path or a filtered path of a element directly from the page.

Its a live CSS, Javascript and HTML editor that is opensource and a wip.

I want a single online web page for my bookmarks. The page should include small windows which opens the following pages:
Fizy, Facebook, Guardian.
There should also be a button for adding a new window with an URL text input.
Here's an illustration of how the page should look: http://i54.tinypic.com/2hrkb48.jpg
I've built a version of this at http://bit.ly/heqEd1, but as you may see, it uses iframes under javascript windows, which can not open frame-breaking sites (like fizy.com), or Facebook.
I'll make the research and but I am not sure how to proceed. Any solution will be accepted, like HTML5, XUL, Flex, AJAX or others. A solution with a local installation(like a Firefox extension) is not preferred, but still be ok.
Note: Piro Sakura has built a Firefox extension called split-browser. There's an element of the project called "subbrowser". An AJAX window that can show a subbrowser MAY solve the problem. I know the page will only be available from Firefox, but that is ok. (Again, a solution without an installation is preferred)
Any suggestions? How should I proceed? What should I learn? Is this possible?
Thanks.
I think you should use a Javascript with iFrames to do this. I'm not too sure what you're trying to accomplish with this, but it should be possible. As for which framework you'll use, it's up to you, but there will be a lot of custom code needed to implement this.
You can make multiple draggable windows in FLEX same as you have in you app
Please check sample as Starting point Movable/Draggable window and its demo
also u knows JS-DESKTOP lib with little customization to achieve that one of them are
jsdesk
sonspring-JQuery based
also you can do this using
Hopes that helps
I am working in Dreamweaver CS4 and implemented JQuery code that I found online for a gallery function.
I am only using a very small part of the gallery functions available, and would like to delete the unused script in order to get more clarity and a cleaner script. But as a JavaScript beginner I can't identify what is important and what is not.
My question: Is there a way in Dreamweaver to view/highlight the JS code that the site is using? I am imagining a tool that you could turn on when running the live view that would visualize the portions of code that is being used.
Or, the other way round, is there a way to highlight the unused code.
The live code button doesn't seem to do this.
Thanks for your help!
My question: Is there a way in Dreamweaver to view/highlight the JS code that the site is using?
No. You would need to use Firebug or a similar javascript tracker/debugger to see how the code is used. The most DW will tell you is which external files are linked to a page.
