Question

Assuming the target page is set up correctly, if the following link is placed on a site’s index.html page, what, precisely, happens at the browser when the link is clicked? Give ALL details.

Answer 1

Whenever, a button or link is clicked(with a link) on page, it can use some actions like GET, PUT,POST. If we want to visit a link, we use GET request. So, These are called Events and these are handled by the Browser. The browser has been instructed, how each of the event is handled. So, When a button is clicked, browser, issues a GET request to the router. The Router knows where to direct the request. It grants the internet protocol if request is external(a link of other site), and it grants the request to internal browser if the link is internal(links on same site).

If the links are internal, the browser issues the function related to the request and the event is handled according to the function calls(lines of code that tell what to do like scrolling down to a target, or rendering another page). The code can be on JavaScript, PHP, Rails, or other platform on which the site is based. When the Browser gets the response, it redirects and performs actions what are entitled in the request.

Most of this work is done by Rendering Engine. The present browsers are completely useful programming suites that can translate and show HTML Web pages, applications, JavaScript, AJAX and other substance facilitated on Web servers. Numerous programs offer modules which expand the capacities of the product so it can show sight and sound data (counting sound and video), or the program can be utilized to perform assignments, for example, videoconferencing, to configuration pages or include against phishing channels and other security highlights to the browser.The rendering engine parses the pieces of HTML report and convert the components to DOM hubs in a tree called the "content tree" or the "DOM tree". It likewise parses both the outer CSS documents also in style components.
