Pruébalo asi:
Código PHP:
<html>
<head>
</head>
<body>
<input type="text" id="flashlink" flashtype="0" flashcolor="green" value="123">
<script language="JavaScript">
function changecolor(which, type, color){
if (type == 0){
if (flashlinks[which].style.color != color)
flashlinks[which].style.color = color;
else
flashlinks[which].style.color = '';
} else
if (type == 1){
if (flashlinks[which].style.backgroundColor != color)
flashlinks[which].style.backgroundColor = color;
else
flashlinks[which].style.backgroundColor = '';
}
}
if (document.all && document.all.flashlink){
var flashlinks = document.all.flashlink;
if (flashlinks.length == null)
flashlinks[0] = document.all.flashlink;
if (flashlinks.length == null){
var flashengine = 'setInterval("changecolor(0, ' + flashlinks[0].flashtype + ', \'' + flashlinks[0].flashcolor + '\')",' + '1000)';
eval(flashengine);
} else
for (i = 0; i < flashlinks.length; i++){
var flashengine = 'setInterval("changecolor(' + i + ',' + flashlinks[i].flashtype + ', \'' + flashlinks[i].flashcolor + '\')",' + '1000)';
eval(flashengine);
}
}
</script>
</body>
</html>
Saludos.
