FAQ > JavaScript and Frameworks
Many websites are now written using a simple HTML web page and a JavaScript libraries or framework to build most of the web page. But Total Validator will normally just test the simple HTML web page sent by the web server, because it does not execute any JavaScript.
The solution is to use our browser extensions. These can send the DOM (the web page after the initial JavaScript has run) from the browser to the Total Validator application to be tested. In this way you can test web pages that users actually see.
You can start a DOM test from the application or the browser, whichever you prefer. With the Pro and CI versions you can test an entire website this way with just one click.
