嗨，我有下面的代码，由4页组成（3 x php，1 x js）。基本原理很简单：
test17a.php：从n单选按钮中进行选择-激发onChange事件以加载test17b.php的内容。这包括从所选单选按钮的ID派生的MySQL查询。
test17b.php：显示一个项目，单击后加载test17c.php。这包括一个从test17a.php和test17b.php 的结果派生的MySQL查询
test17c.php：显示n个项，每个项都是可单击的，当单击这些项时，将运行从test17a.php、test17b.php和test17c.php 的结果派生的MySQL查询
test17d.php显示上述查询的结果。
问题是test17c.php中的值被返回为未定义。我假设这与值之前加载的javascript有关。但我不知道如何更改这一点，以便正确传递值。
如果有人能为我指明正确的方向，我将不胜感激。
##test17.js##
//fired from onchange event on test17a.php
function findB(GroupVal)
{
$("#B").load("test17b.php?GroupVal="+GroupVal).css('display','block');
}
//fired from onClick event on test17b.php
function findC(GroupVal,MasterID)
{
$(".C").load("test17c.php?GroupVal="+GroupVal+"&MasterID="+MasterID).css('display','block');
}
//fired when clicking on one of the items on test17c.php (used to show which item was clicked on
$(document).on('click', 'p.C2', function(evt)
{
var $p = $(evt.currentTarget),
GroupVal = $p.data('GroupVal'),
MasterID = $p.data('MasterID'),
SlaveID = $p.data('SlaveID'),
$div = $p.next();
console.log('3GroupVal='+GroupVal+' | 3MasterID='+MasterID+' | 3SlaveID='+SlaveID);
findE(GroupVal, MasterID, SlaveID, $div);
}
);
function findE(GroupVal, MasterID, SlaveID, $div)
{
$div.load("test17d.php?GroupVal="+GroupVal+"&MasterID="+MasterID+"&SlaveID="+SlaveID).css('display','block');
console.log('4GroupVal='+GroupVal+' | 4MasterID='+MasterID+' | 4SlaveID='+SlaveID);
}

我想你在注释中给你的文件名是test.17c.php，而在url中是test17c.php所以这是一个问题，如果你认为响应是在php文件内容加载之前加载的，那么试试这个
$(<selector>).load(<url>, function() {
// print response so that it will print after response load
alert('Load was performed.');
});
我找到了答案，这有点奇怪。在我的代码中，我有：
print "<p class='"C2'" data-GroupVal='"$GroupVal'" data-MasterID='"$MasterID'" data-SlaveID='"$SlaveID'"> GroupVal = $GroupVal | MasterID = $MasterID | SlaveID = $SlaveID </p>";
但当我仔细查看控制台时，我发现它被读取为：
print "<p class='"C2'" data-groupval='"$GroupVal'" data-masterid='"$MasterID'" data-slaveid='"$SlaveID'"> GroupVal = $GroupVal | MasterID = $MasterID | SlaveID = $SlaveID </p>";
换句话说，所有的数据xxx组件都被转换为小写。这意味着，一旦运行了Javascript，随后运行了$_GET['xxx']，变量都是"未定义的"。
在我的代码中，一旦我将这方面的所有实例转换为小写，它就运行得很好。奇怪的
