Javascript AJAX和PHP中具有相同名称的多个字段

各位

几天前我得到了一些很好的帮助，所以我希望有人能告诉我哪里出了问题。基本上，我要做的是当用户单击按钮时在后台更新MySQL数据库。表单是一系列记录，这些记录具有公共字段名（ID、DSA_编号、Manager_Review等）。现在，代码似乎甚至不会返回成功或失败消息

以下是主页上的脚本：

<script>
                $(document).ready(function(){

                    $("#button").click(function(){

                        var DDD_Number=$("#DDD_Number").val();
                        var Manager_Review=$("#Manager_Review").val();
                        var RID=$("#RID").val();
                        var Services=$("Services").val();
                        var Dues_List=$("Dues_List").val();
                        var ID=$("ID").val();
                        var myrid=$("myrid").val();
                        var Manager_Comments=$("Manager_Comments").val();
                        var President_Comments=$("President_Comments").val();
                        var dataTosend='?DDD_Number='+DDD_Number+'&Manager_Review='+Manager_Review+'&RID='+RID+'&Services='+Services+'&Dues_List='+Dues_List+'&Manager_Comments='+Manager_Comments+'&President_Comments='+President_Comments;
                        $.ajax({
                            type: "GET",
                            url:'baseupdater-test.php' + dataTosend,
                            data:dataTosend,
                            async: true,
                          success:function(data){
                                document.getElementById('stuffhere').innerHTML.text = "Success.";
                                document.getElementById('stuffhere').innerHTML.text = data;
                            },
                            error: function(data){
                               document.getElementById('stuffhere').innerHTML.text = "Failure.";
                           }
                        });
                    });
        </script>

$（文档）.ready（函数（）{
$（“#按钮”）。单击（函数（）{
var DDD_Number=$（“#DDD_Number”）.val（）；
var Manager_Review=$（“#Manager_Review”）.val（）；
var RID=$（“#RID”）.val（）；
var Services=$（“Services”）.val（）；
var应付账款清单=$（“应付账款清单”）.val（）；
var ID=$（“ID”）.val（）；
var myrid=$（“myrid”）.val（）；
var Manager_Comments=$（“Manager_Comments”）.val（）；
var President_Comments=$（“President_Comments”）.val（）；
var dataTosend=“？DDD_编号=”+DDD_编号+”&经理审查=“+Manager_审查+”&RID=“+RID+”&服务=“+Services+”&会费清单=“+Due_清单+”&经理评论=“+Manager_评论+”&总裁评论=”+总裁评论；
$.ajax({
键入：“获取”，
url:'baseupdater-test.php'+dataTosend，
数据：dataTosend，
async:true，
成功：功能（数据）{
document.getElementById（'stuffhere'）。innerHTML.text=“成功。”；
document.getElementById（'stuffhere'）.innerHTML.text=数据；
},
错误：函数（数据）{
document.getElementById（'stuffhere'）.innerHTML.text=“失败。”；
}
});
});

下面是在表上绘制行的代码：

$n = 0;
$o = $n + 1;

$firstday = date('m/1/Y');
if(isset($_GET['MR']))  // If $_GET['MR'] is set ...
{
    $MR = $_GET['MR'];  // Set the variables.
    $PR = $Pres_Rev;
}
else  // If not, select the maximum (latest) Manager Review Date.
{
    $getmr = "select max(STR_TO_DATE(Manager_Review_Date, '%m/%d/%Y')) as Manager_Review_Date,

您的代码

var data= [DDD_Number,Manager_Review,RID,Services,Dues_List,ID,myrid,Manager_Comments,President_Comments];
var datatosend = JSON.stringify(data);
$.ajax({
type: "GET",
url:'baseupdater-test.php',
data:dataTosend,
async: true,
success:function(data){
document.getElementById('stuffhere').innerHTML.text = "Success.";
document.getElementById('stuffhere').innerHTML.text = data;
 },
error: function(data){
document.getElementById('stuffhere').innerHTML.text = "Failure.";
 }
});


正如我所看到的，您试图发送数据两次，第一次是通过url，第二次是使用ajax
data
方法。请纠正我认为这样做是错误的，您应该只发送一次

此外，您必须将数据转换为json格式，以使ajax请求正常工作
现在发生的事情是，由于您的数据格式不正确，您的代码必须卡在ajax中的
数据上。您可以在控制台中看到它。ajax请求不会向您显示任何传递给另一方的值，这是成功或失败未显示的主要原因。
查看las您已经编写的代码的t行
InnerHtml
将其更改为
InnerHtml
谢谢。我已经解决了这个问题。：）它仍然没有正确更新或显示消息，我不知道为什么，但至少已经修复。你能告诉我
stuffhere
在你的代码中的位置吗？我的意思是哪个元素有这个id。它是主文件中的最后一个标记。我没有共享它，因为文件很长。你试着调试这个问题了吗m？代码太多了……有没有办法不用json？数据不是json格式的。就像你说的，如果你想在后台通过ajax加载数据，你必须将数据转换成json格式。别担心，我也会指导你。好的。谢谢你能给我的任何帮助，Kunal。我很感激。：）毕竟你r variables放置此代码，并使用var
dataTosend
删除整行代码。谢谢，Kunal。我已相应地更改了代码，我会让您知道它是如何运行的。我感谢您的帮助。：）
