Question

我需要在表上添加运行时行，然后将数据发送到数据库。我设法完成了大部分工作但是我被困在程序的两个部分上。

我正在使用Ajax检查下拉列表中的可用数量，我希望在相应的行中显示，但是不能，到目前为止我能够提醒正确的值。）
如果我填写任何行，php帖子会向我发送一个小于表单上可用参数的参数，但如果我添加行并且不填写任何信息，请向我发送正确数量的参数。（即如果我添加3个空白行并单击提交，则提交4个值， - ＆gt;因为一行是隐藏的，但是如果我填充屏幕中的任何3行，它只作为参数发送3个帖子为$ name）

function getSpQty(strURL) {
  var xmlhttp;
  console.log(this)
  if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp = new XMLHttpRequest();
  } else { // code for IE6, IE5
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
  }
  xmlhttp.onreadystatechange = function() {
    if (xmlhttp.readyState == 4) {

      if (xmlhttp.status == 200) {
        alert(xmlhttp.responseText);

        document.getElementById('sp').value = xmlhttp.responseText;

      } else {
        alert("There was a problem while using XMLHTTP:\n" + xmlhttp.statusText);
      }
    }
  }
  xmlhttp.open("GET", strURL, true);
  xmlhttp.send(null);
}

这是SPName.php

include_once("dbConn-SP.php");

$spareparts=$_REQUEST['spareparts'];


$tsqls = "select InitialQty from SparepartManagement where GeneralItemDescription ='$spareparts'";




    $params = array();
    $options =  array("Scrollable" => SQLSRV_CURSOR_KEYSET );
    $stmt = sqlsrv_query($connIgms, $tsqls , $params, $options);

    $row_count = sqlsrv_num_rows($stmt);




        while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
               $test = $row['InitialQty'];


            }



echo $test; 

?>

这里是test.php

<?PHP
error_reporting(0);

include_once("dbConn-SP.php");

$Qty = $_POST["col4"];
$IssuedQty = $_POST["col3"];
$name= $_POST["name"];
//Step 3: Insert statment
print_r($name);
for ($i = 1; $i < sizeof($Qty); $i++) {     
            $j=$i-1;
$Insert = "INSERT INTO SparepartTransaction (SPDesc,InitialQty,QtyIssued) Values ".
            " ('$name[$j]','$Qty[$i]','$IssuedQty[$i]')";   
$stmt = sqlsrv_query($connIgms,$Insert);            

            }
sqlsrv_close($connIgms);
?>

遗憾的是，我没有足够的声誉在这里发布图片，所以这里是我屏幕上实际显示的链接 http://prntscr.com/749n4n

我想要的是，而不是提醒 - ＆gt;警报（xmlhttp.responseText）; 我希望这个值显示在下拉列表旁边的单元格上。任何帮助将不胜感激。

显示相应行中ajax的返回值
