An Internet site has URL like www.manyresultpages.net/cgi-bin/search.cgi?recnum=7777&
Can I make my Dad a local static html page (for his PC) with one input field and a submit button, that will modify the above URL, replace "7777" with the input text and open the new URL in a new tab on button click?
I'm HTML-challenged, googled for 45 mins without getting far. Did learn jsfiddle.net is down. Can load jQuery if that would help.
