phpurlxmlhttprequest
index.php里：
var request = new xmlhttprequest();
request.open(post,test.php);
request.setrequestheader(content-type,application/x-www-form-urlencoded);
var str=name=+url;
request.send(str);
text.php里：
$url=$_post['name'];
echo $url;
两个文件在同一工程下，url是个变量,text.php执行会提示undefined index:name
readystate=4 status=0 ,请问哪儿出错了
