You can set event handlers within HTML TAG using syntax like
  • onclick="whattocall(arg1,arg2...)"
Alternatively set event handler explicitly with
  • document.myform.mybutton.onclick=anotherfunction; // where anotherfunction is a function without arguments and there are NO () in this syntax but you must have () when specifying inside TAG
  • Also note JavaScript is case sensitive and onclick is ALL lower case here but in HTML which is not case sensitive you are free to use any case in ONclicK= " .. " syntax
