“Disabling” an HTML table with Javascript

由 跟風遠走 提交于 2019-12-03 07:08:04
I've seen this done in a lot of sites recently, but can't seem to track one down. Essentially I want to "disable" an entire panel (that's in the form on an HTML table) when a button is clicked.

I do not need to adjust this from the webpage, a preset coded into the script will suffice. The code of the page listed above is: <!DOCTYPE html "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3
