I am familiar with the concept that when a form is submitted say to a servlet the value of the text field is available by name to the servlet.
So for example

The servlet can access the value by


Now I know that in java script something like


This statement however sets the runtime value of the textbox and does'nt Adjust the original HTML (ie it doesnt add the typed data in the textbox in the value section).
However the typed text is still available to the servlet why is that ? does the submit button actually insert the content of textboxes in the value fields??

The HTML is just the source. Once the DOM has been created, the elements in the DOM are all that matter. So no, the value attributes are never changed, but it doesn't matter.

It's pretty much like asking if assigning a new value to a Java variable at run-time changes the source code of the Java class.
