your type checking message unnecessary, in case want keep it:

function settext(elementid, message){      if((typeof elementid == 'string') && (typeof message == 'string')){           document.getelementbyid(elementid).innerhtml = message;      }  }    settext("foo", "1")  settext("foobar", "2")  settext("bar", "3")  settext("barfoo", "4")

<p id="foo"></p>  <p id="foobar"></p>  <p id="bar"></p>  <p id="barfoo"></p>
