} else {// dh

var range = document.Selection.createrange ();

range.movestart ("charakter",-otxt1.value.length);

cursurposition = Bereich.text.length;

var otxt1 = document.getElementById ("txt2");

var cursurposition = -1;

if (otxt1.SelectionStart) {// 非 IE 浏览器

OTXT1.SelectionStart = i;

} else {// dh

var range = otxt1.createTextrange ();

Range.move ("Charakter", i);
