mydoc=document.getElementsByClassName("forth"); returns a HTMLCollection object. HTMLCollection does not have a innerHTML property. You need to access a specific element of the collection through it's index. I.e.
mydoc[0].innerHTML = "change me please";
or
mydoc = document.getElementsByClassName("forth")[0];
