Q1276 How can I read the text written in one frame by clicking a button on the other frame?

<script language="JavaScript"><!--
function getText()
    if (document.all) {
        for (var i=0;i < parent.otherFrameName.document.all.length; i++)
            if (parent.otherFrameName.document.all(i).tagName == 'BODY')
                alert(parent.otherFrameName.document.all(i).innerText);
            }
        }
    }
}
//--></script>

<form>
<input type="button" onClick="getText()" value="Get Text From Other Frame">
</form>
