我有这两个文件：

new_aircraft.php

<body>
<script>
//Ajax Script
function require(){
    try{
    req = new XMLHttpRequest();
    }catch(err1){
        try{
        req = new ActiveXObject("Microsoft.XMLHTTP");
        }catch(err2){
            try{
            req = new ActiveXObject("Msxml2.XMLHTTP");
            }catch(err3){
            req = false;
            }
        }
    }
return req;
}


var request = require();

function callAjax(){
var ramdom = parseInt(Math.random()*999999999);
valor = document.getElementById("numberclasses").value;
var url="classes.php?Value="+valor+"&r="+ramdom;
request.open("GET",url,true);
request.onreadystatechange = answerAjax;
request.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
request.send(null);
}

function answerAjax(){

    if(request.readyState==4){
        if(request.status==200){
        //alert(request.responseText);
        document.getElementById("classes").innerHTML=request.responseText;
        }else{
        alert("ha ocurrido un error"+request.statusText);
        }
    }
}

</script>
<?

$boton = $_POST['enviar'];
$nombre = $_POST['nombre'];

    $ICAO = strtoupper($ICAO);

    <tr><td class=Forms>Name: </td><td><input type="text" value="Airbus A320" name="nombre" /></td></tr>
    <tr><td class=Forms>Price: </td><td><input maxlength="9" value="1000000" type="text" name="precio" /> €&lt;/td></tr>

    <tr><td class=Forms>Number Classes: </td></td><td><select name="numberclasses" id="numberclasses" onchange="callAjax()">

        ?>
    </select></td></tr>


<tr><td id="classes" ></td></tr>

    <tr><td class=Forms>Capacidad: </td><td><input maxlength="3" value="150" type="text" name="pax" /> pasajeros</td></tr>
    </table><br />
    <input type="submit" name="enviar" value="Insertar"/>
    </form>
    <?
}
?>
</body>
</html>

类.php

 <?php
$value = $_GET['Value'];

if($value == 1){


    ?>


<thead>
    <td class=Forms>First Class: </td><td><input maxlength="3" value="150" type="text" name="pax" /></td>
</thead>


<?php
}

?>

而当我“选择类数”1时的结果是http://i48.tinypic.com/erbfnn.png（这是一张图片，请看）。

头等舱部分的顺序不正确。它应该低于 Number Classes，但它是第一个。头等舱部分不尊重其他部分的宽度。

我该如何解决？

的孩子<table>只能是<thead>, <tbody>, 或<tfoot>; 你也可以有<tr>，它会自动把它们包起来<tbody>。

所以改变：

<div id="classes"></div>

至：

<tr><td id="classes"></td></tr>

您也有一个<form>，但</form>元素，您需要匹配它们并正确嵌套。您不能在表格末尾和内部开始表格，因此请摆脱</form>表格内部的多余部分。
