我对此问题感到震惊，我有一个名为view employee的页面，当我们点击显示所有雇员时，我为每个员工编辑按钮，下面是相应的页面
echo "<form class="form-horizontal id="update_form" name="update_form" method="POST" action="update_employee_details.php" enctype="multipart/form-data">
<legend>Edit Employee details for '.$id.'</legend>

我的js部分在这里
$(document).on('click', '#btn_save_changes', function (event) {
var formValues = $('#update_form').serialize();
alert(formValues);
$.ajax({
url: 'view_edit_delete/update_employee_details.php',
type: 'POST',
data: formValues,
success: function (response) {
alert(response);
}
}
});
});
当我使用警报时，我变空了:-(。我尝试了一切var formValues= new FormData($(this)[0]);
但仍然没有结果
答案 0 :(得分：1)
你错过了（“） 在
<form class="form-horizontal" id="update_form"
在«form-horizontal»之后
的情况
<form class="form-horizontal id="update_form"
表单的ID变为“update_form”（带有前导空格），$('#update_form')没有任何内容。
调试应用程序时，请不要犹豫，按F12并使用控制台手动尝试代码的简单部分。使用控制台很容易发现$('#update_form')找不到元素。然后调查它为什么会发生。
答案 1 :(得分：1)
首先请不要将您的HTML代码放在php中。
然后
<form class="form-horizontal
<form class="form-horizontal"
关闭班级标签
并且标准不要将HTML代码与PHP混合。
用于设计使用格式良好的HTML代码并在html标签中提供动态性放置php值。它的工作很简单，使代码易于理解。
答案 2 :(得分：-1)
执行：php里面的html ... 不要：html里面的php echo语句...... 不要简单地在php中使用echo来获取html标签，为什么因为像netbeans这样的IDE不会出现错误你在php echo语句中提出的错误。这不是编码的最佳实践。或者如果你真的需要在你想要的地方使用php，你可以使用“＆gt;而不是echo”..
