Ajax 之后的 Javascript [重复]

可能的重复：
在 AJAX 请求之前使用 JavaScript 获取日期 https://stackoverflow.com/questions/14416443/obtain-dates-with-javascript-before-ajax-request

我有一个这样的 Ajax 请求：

function ajaxrequest(str){

    var aircraft = $("#resultdiv");
        aircraft.load("./other_file.php?icao="+str, function(){
        });
    }

如果我将 Javascript 放入 other_file.php 中，则不起作用。我不知道为什么？但如果直接使用 javascript 代码就很有趣！但我需要这个功能。如何使用 Javascript 将函数更改为有趣的结果？

例如：

如果 other_file.php 有这个：

<script>
function example(){

        var id = document.getElementById('id').value;
                $("div2").text(id);
    }
</script>

这不起作用，因为它需要获取 var id，但如果该元素的值为 2365。获取它的 javascript 代码document.getElementById('id').value;不起作用，因为 javascript 不起作用。但是如果我直接执行此操作而不是通过函数 ajaxrequest 执行此操作，则一切正常。

这是 other_file.php 的真正内容

<script>
    $(function() {
        $("#editaircraft")
            .button()
            .click(function editForm() {
        });
    });

    function editForm(){

        var icao = document.getElementById('icao').value;
        var name = document.getElementById('name').value;
        var weightempty = document.getElementById('weightempty').value;
        var weightfull = document.getElementById('weightfull').value;
        var cargofull = document.getElementById('cargofull').value;
        var cruisespeed = document.getElementById('cruisespeed').value;
        var range = document.getElementById('range').value;
        var price = document.getElementById('price').value;
        var firstclassseats = document.getElementById('firstclassseats').value;
        var businessclassseats = document.getElementById('businessclassseats').value;
        var economyclassseats = document.getElementById('economyclassseats').value;
        ajax.open("POST","edit_aircraft_process.php",true);
        ajax.onreadystatechange=function(){
            if(ajax.readyState==4)
            {
            refreshTable(function(){$("#loadingdialog").dialog('close');});

            refreshTable(function(){$("#result").fadeIn(); document.getElementById("result").innerHTML=ajax.responseText;});
            setTimeout(function() { $("#result").fadeOut() }, 5000);
            }
        }
    ajax.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    ajax.send("icao="+icao+"&name="+name+"&weightempty="+weightempty+"&weightfull="+weightfull+"&cargofull="+cargofull+"&cruisespeed="+cruisespeed+"&range="+range+"&price="+price+"&firstclassseats="+firstclassseats+"&businessclassseats="+businessclassseats+"&economyclassseats="+economyclassseats);
    $("#editaircraftdialog").dialog('close');
    $("#loadingdialog").dialog('open');
    }
</script>

<?php
require_once ('../../config.php');
$icao = $_REQUEST["icao"];

$query = "SELECT * FROM aircrafts WHERE ICAO = '$icao'";

$result = mysql_query($query);
if (!$result)

echo $row["EconomyClassSeats"] . "></td></tr>";}

echo '<tr><td><input id="editaircraft" type="submit" value="Edit Aircraft"></td></tr>';

}
echo "</table>";
?>

</form>

变量的获取是未定义的！

var aircraft = $("#resultdiv");

function ajaxrequest(str){
    $.get("other_file.php?icao="+str, function(result){
          aircraft.append(result);
    });
}

其他文件.php

...

    <script>
            $("#editaircraft")
                .find('button') /* ??? */
                .click(editForm);

        function editForm(){

            var icao = document.getElementById('icao').value;

                setTimeout(function() { $("#result").fadeOut() }, 5000);
