使用xmlhttprequest发布数据？

Question

Hi guys I'm trying to delete a file with Ajax and I have this code:

functions.js:

function deleter(val){
var value = val.replace(".",",");
var del = new XMLHttpRequest();
del.addEventListener("load", completedelete, false);
del.open("POST","index.php?action=delete",true);
del.send("file="+value);
}

index.php:

if(isset($_REQUEST['action'])&& $_REQUEST['action']=="delete"){
if(!isset($_POST['file'])){
    echo("not set");
}
if(unlink($_POST['file'])){
    echo"1";
}else{
    echo"0";
}
}

and I always get "not set" in the response with the 0 .

any one can help me?

Try to add

del.setRequestHeader("Content-type","application/x-www-form-urlencoded");

before del.send().
