使用带有POST的XMLHttpRequest()

我尝试使用POST方法向php页面发送值,但它无法正常工作。

javascript代码为:

 function op_infoMeeting(id_met){
            $('#modalInfoMeeting').find('.modal-title').text("Info 
Meeting");
            $('#modalInfoMeeting').modal('show');
    var xhttp = new XMLHttpRequest();
    xhttp.open("POST", "infoMet.php", true);
    xhttp.setRequestHeader("Content-type", "application/x-www-form- 
urlencoded");
    xhttp.send(id_met);
    return true;

  }

infoMet.php的代码是:

 <?php


$idMet=$_POST["id_met"];

 echo $idMet;
include "DB.php";

$query=mysqli_query($connessione,"select title,date,place from meeting where 
 meeting_id=".$idMet."");


 while($row=mysqli_fetch_array($query,MYSQLI_ASSOC))
   {

    echo "Staff Name:" . "<input type='text' value='" . $row['name'] . "'>";
    echo "</br>";
    echo "Contact No.:" . "<input type='text' value='" . $row['title'] . 
"'>";
 }
?>

它给了我这个错误:

未定义的索引:第4行的infoMet.php中的id_met
