DOM: Inserting text between <head> and <body>

#1 July 24th, 2005, 07:05 PM

Hi.

I'm trying to insert some text between <head> and <body> but I'm
not able.

I try with:
--------
bodyPoint = document.getElementsByTagName('body');

var myLink = document.createElement("a");
myLink.href = "http://www.yahoo.com";
myLink.innerHTML = "Yahoo";
bodyPoint.insertBefore(myLink, bodyPoint);
---------

but it doesn't work. I get this error
-----------
bodyPoint.insertBefore is not a function
--------------

What am I doing wrong? Thx.

Good, because it makes no sense what so ever to place text between the
HEAD element and the BODY element.

A call to the getElementsByTagName method returns an object implementing
the NodeList interface.

The NodeList interface does not implement an insertBefore method.

Failing to RTFM, or failing to think about their content.

window.onload=function(){
htm = document.getElementsByTagName('html')
myLink = document.createElement("a");
myLink.href = "http://www.yahoo.com";
txt = document.createTextNode('Yahoo')
myLink.appendChild(txt)
htm[0].insertBefore(myLink,document.body);
alert(htm[0].innerHTML)
}

not correct : you got the body tree (collection of all body tags)
Hu ? there is only one ?
Does browser know you use a collection instruction to catch one object ?

bodyPoint = document.getElementsByTagName('body')[0];

because ? bodyPoint is an array

to which one of its elements the browser will address insertion ?
