Do a view source in the browser to see what is actually written. Post that.

And onmouseout doesn't need "javascript :"
onmouseout=func tionName()
not
onmouseout=java script:function Name()

Your function is called switchColors(), you're calling ...
onmouseover="sw itchColor(this, 'yellow');" ...

You probably want to use -var- to ensure your function variables are
local to the function, and you don't really need item():

function switchColor(ele ment, color)
{
var links = document.getEle mentsByTagName( 'a');
for (var ii = 0; ii < links.length; ++ii)
{
links[ii].style.color = 'blue';
}
element.style.c olor = color;
}

You probably want some appropriate error handling added for browsers
that do no support the methods and properties you are attempting to
access:

function switchColor()
{
return;
}
function switchColorEnab led(element, color)
{
var links = document.getEle mentsByTagName( 'a');
for (var ii = 0; ii < links.length; ++ii)
{
links[ii].style.color = 'blue';
}
element.style.c olor = color;
}
window.onload = function()
{
if (document.getEl ementsByTagName )
{
var links = document.getEle mentsByTagName( 'a');
if (links.length > 0 && links[0].style)
{
switchColor = switchColorEnab led;
}
}
}

I'm still making the assumption that if the first link I retrieve
supports the -style- property, they all will, but I would hope that it's
a fairly safe assumption to make.

Most probably because it does generate invalid HTML.

<http://validator.w3.or g/>
[color=blue]
> <a href=\"$PHP_SEL F?action=list_r ecords&cur_ page=$varray&id =$id\"
> onmouseout=java script:switchCo lors(this, 'yellow')> $array </a></td>";[/color]

Should read

echo <<<EOD
<a
href='${PHP_SEL F}?action=list_ records&cur _page=${varray} &id=${id }'
onmouseout="swi tchColors(this, 'yellow')">${ar ray}</a></td>
EOD;

But then,

1. why don't you use forms and submit buttons in the first place?

echo <<<EOD
<form action="list_re cords">
<input type="hidden" name="cur_page" value="${varray }"
<input type="id" name="cur_page" value="${id}"
<input type="submit">
</form>
EOD;

2. why don't you just use CSS for formatting links hovered on or active?

a:link {
color: black;
background-color: yellow;
}

a:link:hover {
color: yellow;
background-color: black;
}

Your method(ology) is flawed since a) not only links are specified with
the `a' element and b) not only the `a' element creates a (hyper)link.

Furthermore, I don't see a test for that host object's method. Don't
assume it is present or you will cause script errors where it is not.

More efficient would be

for (var i = links.length; i--;)
[color=blue]
> links.item(i).s tyle.color = 'blue' ;[/color]

links[i].style.color = 'blue';

will suffice according to

<http://www.w3.org/TR/DOM-Level-2-HTML/ecma-script-binding.html>

But text color and background color should never be specified
without the other: <http://www.w3.org/QA/Tips/color>

You really want to learn style sheets, namely CSS, ...
