function validation(){
var nom=document.forms.recommander_ce_blog.nom.value;
var email=document.forms.recommander_ce_blog.email.value;
var message=document.forms.recommander_ce_blog.message.value;
valid.onreadystatechange = alertContents;
valid.open('get',"validation_recommander_ce_blog.php?nom="+nom+"&email="+email+"&message="+message+"&id="+Math.random(), true);
valid.setRequestHeader('If-Modified-Since','Wed, 05 Apr 2006 00:00:00 GMT');
valid.send(null);

}
function alertContents(){
if (valid.readyState == 4) {
result = valid.responseText;
var div=document.getElementById('recommander_ce_blog_error_message')
div.innerHTML = result;
if (div.innerHTML=="<b>Merci!</b>"){
document.getElementById("recommander_ce_blog").style.display="none";
}


}
}

<form action="javascript:validation()" id="recommander_ce_blog" name="recommander_ce_blog" >
<table style="height: 148px;" border="0" width="282">
<tr>
<td>nom:</td>
<td><input name="nom" type="text" /></td>
</tr>
<tr>

Have you added alert statements to figure out where it is breaking?

Do you have error message?

[rnd me]

move valid=new xhr(); into the function validation(), along with function alertContents()...

additionally, try assigning onreadystatechange after the .open(), not before.


also, .innnerHTML is not standardized, check against the string instead:
if (div.innerHTML==..) becomes if (result==...)
