I am writing a plugin for google chrome which goes and extracts some data for a webpage and saves it to a local db. I have covered all the parsing of the pages but some info is on a different tab and for now requires me to navigate manually as it is not a basic url but a javascript. My quiestion is, is there a way to script calling a script on the page i am parsing to force the postback and if so how would i go about it. If not is there another way to solve this ?
Below are some links i would like to call from my script on the webpage

I want to download some code from an HTML website but the data that I need appears after the JavaScript loads (as i know). I tried WebClient but this gets only the HTML code without any JS changes and as far I know there is nothing more I can do. Now I'm trying WebBrowser in WPF and Forms. I have WebBrowser control and I'm navigating to my url address but I'm getting JS errors and scripts are still not loading.
webBrowser1.Navigate(new Uri("http://www.polskieszlaki.pl/atrakcje/woj-slaskie/"));
How to get webpage fully loaded with all scripts?
Btw. I don't need a web browser, I just need to collect some data so the HTML code after scripts are loaded is enough for me.
I have a VB.NET (2010) forms project, and I want to read a webpage that has a java script on it, generating log output.
But when I do a request to the webpage, I only get the static part of the page.
When I fire the URL in a browser, it displays dynamic content and is updated regularry.
Whats the best wat to execute javascript remotely from vb.net.
I was wondering if there was a way to prevent a user from saving/downloading a web page? Specifically, I mean not letting them have access to the data displayed through my web application on their own machine?
I've heard that this is not possible since the browser must have access to the source code/data, but at the same time, I've noticed that if I to my gmail account, open an email, save the page, but when I try to open that page on my computer, it doesn't work. Furthermore, if I click "view source", I can see that even the source does not display the entire email message, even though the email is opened in my browser.
How it's possible for gmail to prevent me from seeing that email data?
Thats what called rendering pages using dynamic data without refreshing page (AJAX). The entire page source code is not downloaded in one go and components within the page request data asynchronously to display content. Try googling it and you will find more information.
In View source you can only see the HTML, CSS, JavaScript codes. No one can copy any dynamic code (PHP) from view source.
You can't stop anyone to see your html,css code in browser, as we are having view source option.
Maximum what you can do is disable right click on your page. Thant can be done through JavaScript.
I have a web service that works through giving users javascript to embed in their code. Users can also place that code on other sites to make it work there. However I also need to allow users to create a blacklist of sites that the JS should not function on. For example, a competitor or an inappropriate site.
Is there a way to check where our JS files are being loaded from, and block loading or break functionality on a per account basis?
Edit: The javascript loads an iframe on the site, so another solution would be to somehow block certain domains from loading an iframe from our server, or serve different content to that iframe
Edit 2: We're also trying to avoid doing this from with the JS because it could be downloaded and modified to get pass the block
Inspecting the url of the page
Yes, the javascript file, when it starts executing, can inspect window.url and see if the url of the main document is ok.
To see where the script was loaded from
It can also go through the dom, looking for the script node which brought in the javascript file itself and see from where the JS was loaded.
However
Anyone can load the javascript into a text editor, then change it to eliminate the tests, then host the modified JS on their own server. Obfuscating or minimizing the JS can slow someone down but obscurity is not security.
One thing you could do is have the javascript load another javascript file. That you serve from the server at a given url. The trick here is that that url will not go to a file but to a server end point that will return a javascript file. The you have that endpoint check for the routes for that user and decide if it will return the javascript you want to work or an error javascript of some kind.

I want to create javascript widget similar to linkedin Member profile. https://developer.linkedin.com/plugins/member-profile-plugin?button-type-inline=true
On my site the user can manage some data.
I want to allow for user to copy some HTML code and insert in his site HTML to display the data.
I want HTML code looks like:
<script src="http://mysite.com/code.js?userid=123"></script>
And if user inserts this code in his site then javascript code is loaded and data are displayed (widget displayed)
How to do this? I know about crossdomain restrictions. But in case of linkedin this is not the problem. Their widget works fine.
Thanks.
UPDATE.
As i understand from comments, it is not the problem to display any data in page that includes my javascript file. I am going to do tests.
Either the data is embedded inside the script, or it is loaded via JSON-P
