    阿贾克斯后的Javascript阿贾克斯后、Javascript

    2023-09-10 15:53:44 作者：国产姑凉必须坚强

    可能重复：   Obtain日期与JavaScript的AJAX请求之前

    我有一个Ajax请求是这样的：

     函数ajaxrequest（STR）{

    VAR飞机= $（＃resultdiv）;
        aircraft.load（./ other_file.php？国际民航组织=+ STR，函数（）{
        }）;
    }

    如果我把JavaScript中的other_file.php鸵鸟政策作品。我不知道为什么？但是，如果使用JavaScript code直接工作的乐趣！但我需要的功能。我怎样才能改变功能，这样的结果与JavaScript的乐趣？

    例如：

    Java 和 JavaScript 的关系 你别整蒙了

    如果该other_file.php有这样的：

     ＆LT;脚本＆GT;
例如，函数（）{

        。VAR ID =的document.getElementById（'身份证'）值;
                $（DIV2）文本（ID​​）;
    }
＆LT; / SCRIPT＆GT;

    这鸵鸟政策工作，因为它需要获得VAR ID，但如果元素的值2365的JavaScript code，以获得它的document.getElementById（'身份证'）。值; 鸵鸟政策工作，因为JavaScript鸵鸟政策工作。但是，如果我的功能直接这样做，并没有ajaxrequest一切工作正常。

    这是真的含有other_file.php的

     ＆LT;脚本＆GT;
    $（函数（）{
        $（＃editaircraft）
            .button（）
            。点击（函数editForm（）{
        }）;
    }）;

    功能editForm（）{

        VAR国际民航组织=的document.getElementById（'ICAO）的价值。
        。VAR名称=的document.getElementById（'名'）值;
        。VAR weightempty =的document.getElementById（'weightempty'）值;
        。VAR weightfull =的document.getElementById（'weightfull'）值;
        。VAR cargofull =的document.getElementById（'cargofull'）值;
        VAR cruisespeed =的document.getElementById（'cruisespeed'）值。

        。VAR价格=的document.getElementById（'价格'）值;
        VAR firstclassseats =的document.getElementById（'firstclassseats'）值。
        VAR businessclassseats =的document.getElementById（'businessclassseats'）值。
        VAR economyclassseats =的document.getElementById（'economyclassseats'）值。
        ajax.open（POST，edit_aircraft_process.php，真正的）;
        ajax.onreadystatechange =功能（）{
            如果（ajax.readyState == 4）
            {
            refreshTable（函数（）{$（＃loadingdialog）对话框（亲密）;}）;

            refreshTable（函数（）{$（＃结果）淡入（）;的document.getElementById（结果）的innerHTML = ajax.responseText;}）;
            的setTimeout（函数（）{$（＃结果）淡出（）}，5000）;
            }
        }
    ajax.setRequestHeader（内容类型，应用程序/ x-WWW的形式urlen codeD）;
    ajax.send("icao="+icao+"&name="+name+"&weightempty="+weightempty+"&weightfull="+weightfull+"&cargofull="+cargofull+"&cruisespeed="+cruisespeed+"&range="+range+"&price="+price+"&firstclassseats="+firstclassseats+"&businessclassseats="+businessclassseats+"&economyclassseats="+economyclassseats);

    Possible Duplicate: Obtain dates with JavaScript before AJAX request

    I have an Ajax Request like this:

    function ajaxrequest(str){

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

    If I put Javascript in the other_file.php don´t works. I don´t know why? But If use the javascript code directly works fun! But I need the function. How Can I change the function to the result of this with Javascript works fun?

    For example:

    If the other_file.php have this:

    <script>
function example(){

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

    This don´t work because it needs obtain the var id, but if the element has the value 2365. The javascript code to obtain it document.getElementById('id').value; don´t works because javascript don´t work. But If I do this directly and no by the function ajaxrequest all works fine.

    This is the really contain of the other_file.php

    <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;
