我知道这个问题已经被问过并且回答了很多次但是对于我的生活我无法得到解决方案来处理我的代码。我相信如果我重新编写我的所有代码，我最终会让它正常工作，回想起我在这个问题上花费的时间，我应该重做所有代码...但我现在很好超出我的截止日期，只需要一个工作原型...
有人可以建议如何在不重新加载页面的情况下更新单个页面上的多个表单吗？我很擅长PHP，并且在BEST中使用JS / JQuery / AJAX完成noob。我的html / php在一个文件中，我相信这是导致我最多的问题/是让我的AJAX表单处理工作的最大障碍。
基本上，我希望用户：
从表单组1（联赛冠军）中的多个下拉列表中选择团队，并在更新时使用新选择的团队更新我的数据库，而无需重新加载页面。
编辑每场比赛的球队得分和得分提交/更新，用新得分更新数据库。
对于每个要求，有多种形式（每个匹配1个，每个匹配1个）所以我在每个表单上设置了一个类以及一个id。
所有内容都可以通过PHP工作，但是每次提交内容时表单提交都会重新加载页面，这并不理想。
我已经尝试过来自http://scotch.io/tutorials/javascript/submitting-ajax-forms-with-jquery的AJAX代码以及来自SO的众多解决方案，但没有运气。我不知道如何编辑代码以适应我的情况。
我不确定哪些代码可以帮助有人回答此问题，因为我的所有代码都在一个页面中，并且在此帖子中复制/粘贴可能太长。我将提供任何有需要的信息/数据来帮助我。我在交付后7周（这对我和朋友来说是一个个人项目，所以没有太大的交易......但是真的想要完成这个）。
好的，这是我的代码。它非常糟糕，我正在重构它以利用功能和更好的查询等。但这就是我目前所希望的，并且希望能够使用＃34; work＆＃34;在我重新设计之前......（我希望根据我的问题更新的部分在评论中注释了STACKOVERFLOW）。希望这有助于有人帮助我，因为我仍处于僵局。

我会尝试在一个例子中向你解释，我希望你能理解它。 很抱歉，但是你的代码很长，并不是最好的代码，我现在没有时间理解它。
假设您要更新数据库表格中的名称，并且您不想拥有多个文件。
<?php
$connect = mysqli_connect('hostname', 'username', 'pass', 'dbname');
if(mysqli_connect_errno()){
echo 'connection error: ' . mysqli_connect_error();
}
function update($name, $id){
mysqli_query($connect,
"UPDATE `my_user_table` SET `name`='$name' WHERE id=$id")
or die(mysqli_error($connection));
$success = '<p>Success</p>';
return $success;
}
if(isset($_POST['name']) && isset($_POST['id'])){
$myupdate = update($_POST['name'], $_POST['id']);
echo $myupdate;
exit;
}
?>
<div id="formcont">
<form id="updateform" name="update" method="post">
<input type="text" name="name" id="name" />
<input type="hidden" name="id" value="1" />
<input type="submit" id="submit" name="submit" value="submit" />
</form>
</div>
<script>
jQuery(document).ready(function(){
$('#submit').click(function(){ //or you can use on() instead of click()
var formdata = $('#updateform').serialize();
$.ajax({
type: "POST",
cache: false, //or if you want cache delete this line
data: formdata,
success: function(data){
//do whatever you want here
//for example remove form and print a success text
$('#updateform').remove();
$('#formcont').append(data);
}
});
return false;
});
});
</script>
这只是一个例子，你如何在同一个文件中使用你的php函数并使用ajax。
