可能重复：
在 AJAX 请求之前使用 JavaScript 获取日期

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 放在 other_file.php 中不起作用。我不知道为什么？但是如果直接使用 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，但如果元素的值是 2365。获取它的 javascript 代码document.getElementById('id').value;不起作用，因为 javascript 不起作用。但是如果我直接这样做而不是通过函数 ajaxrequest 一切正常。

这是 other_file.php 的真正包含

<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>

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

}
echo "</table>";
?>

</form>

vars 的获取是不确定的！
