If a website uses AJAX and JavaScript to load content, it may be difficult to scrape data from the site. The data may be dynamically generated and stored in a JavaScript variable, making it inaccessible to a web scraper.
This question is very broad and could have many different answers. Some tools that could be used to scrape data from a website that uses AJAX and JavaScript are Selenium, BeautifulSoup, and Scrapy.
This guide here can help you understand how to use Scrapy to scrape AJAX and JavaScript.
I am developer. i am developing a web application, in which, i need to display/embed docx file in div/web page part.
I have tried google api with using iframe code but not working like -
<iframe src="http://docs.google.com/gview?url=http://example.com/my.docx&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>
but my application can not access by outside of my company. so this is not public documents. we can not upload the documents on google server.
So i am very confuse about the case ago a lot of time.
Can we dispaly docx file into web page ?
Please give a suggestion to resolve this issue.
Thanks.
As of just now, you can try https://nativedocuments.com/
Native Documents has a component you can embed to view or edit Word (doc/docx) files in a web app. You can host it, so your documents aren't transmitted over the public internet.
It is commercial software, but there are free tiers which may be enough for you.
Disclosure: I have an interest in Native Documents.
I m developing a Single Page Application (SPA). So, I use to refresh the page's HTML's content dynamically using Ajax requests.
I'd like to register to the DoubleClick for Publishers program, but I m wondering if my SPA is able to integrate advertising due to its dynamic content loaded without refreshing the page.
I saw this link: https://support.google.com/dfp_sb/answer/3058726
So I assume it's ok. But I'd like to be certain before starting using DFP. Could someone confirm please?
Then, sometimes I m using external html pages that I still load using Ajax. Should I consider writing the advertising banners JavaScript inside these external views, or directly inside the master page of my app?
Last question: How can I manage users having an adblocker software installed? Am I allowed to detect the presence of an adblocker software using JavaScript and then execute some specific code for this kind of users?
I'm working in a SPA and working with DFP successfully. Here is my feedback to your questions:
So I assume it's ok. But I'd like to be certain before starting using
DFP. Could someone confirm please?
Yes, you can refresh the banners using the method you are refering in the link you shared
Then, sometimes I m using external html pages that I still load using
Ajax. Should I consider writing the advertising banners JavaScript
inside these external views, or directly inside the master page of my
app?
To load them externally will bring you to lower performance results. You can control everything from the main page and you will have better results.
Last question: How can I manage users having an adblocker software
installed? Am I allowed to detect the presence of an adblocker
software using JavaScript and then execute some specific code for this
kind of users?
This is something I have not started to work on it but you can detect (like forbes.com is doing on it website) and there are also projects on dealing with this.

Have a look at doing this with an HttpHandler.
HttpHandler Example: http://www.wrox.com/WileyCDA/Section/id-291916.html
If your're using MVC have a look at:
