我有一个ajax脚本，在按钮点击时提交表单，脚本在提交时将表单数据附加到URL，这对任何标准都不安全，该脚本适用于除当前正在调试的表单之外的其他表单。只需用令人讨厌的长网址重新加载页面。
编辑：将form form method =“post”添加到表单但仍无法正常工作。解决网址问题
这是我的ajax脚本：
$("form#PostItemz").click(function(){
var formData = new FormData(this);
$.ajax({
url: 'inc/modules/post_data.php',
type: 'POST',
data: formData,
async: false,
success: function (data) {
alert(data);
},
cache: false,
contentType: false,
processData: false
});
return false;
});
这是我的html表单：
<form method="post" id="PostItemz" class="post publisher-box" >
<div class="panel panel-white post panel-shadow">

inc / modules / post_data.php中的脚本所做的就是回显“hello world”;但似乎没什么用。

不要忘记添加event.preventDefault()行以避免浏览器执行默认行为，即在提交时重新加载页面。
尝试类似
的内容$("#PostItemz").on('submit', function(event){
event.preventDefault()
var formData = new FormData(this);
$.ajax({
url: 'inc/modules/post_data.php',
type: 'POST',
data: formData,
success: function (data) {
alert(data);
},
cache: false,
contentType: false,
processData: false
});
});
这至少可以解决重装问题。另外，如果您要定位表单，请使用提交事件：$("#form_id").on('submit', function() {//do stuff})。如果您想要自己定位按钮，那么您可以执行$("#button_id").on('click', function() {//do stuff})但是对于表单我会建议第一个解决方案。
编辑：如果您将代码放在头部，它会在之前加载页面的其余部分，从而尝试绑定到不存在的ID（在处理脚本的时间）。为避免这种情况，您应该：
将代码放在正文的末尾，就在</body>代码
使用$(function() {//stuff})（缩写为
$(document).on('ready', function() {//do stuff})）结束你的
jquery代码，基本上告诉浏览器：“等待整页
在执行此脚本之前加载“
后者在您的案例中翻译为以下代码：
$(function() {
$("#PostItemz").on('submit', function(event){
event.preventDefault()
var formData = new FormData(this);
$.ajax({
url: 'inc/modules/post_data.php',
type: 'POST',
data: formData,
success: function (data) {
alert(data);
},
cache: false,
contentType: false,
processData: false
});
});
});

您没有点击表单，而是提交
$("#PostItemz").on('submit', function(){
var formData = new FormData(this);
$.ajax({
url : 'inc/modules/post_data.php',
type : 'POST',
data : formData,
success : function (data) {
console.log(data);
},
contentType: false,
processData: false
});
return false;
});
