我正在使用ajax提交表单。然后它在PHP中处理,在response
我得到整个PHP / HTML代码。从PHP发回“响应”作为变量的正确方法是什么?
我的JS
$.ajax({
url: 'index.php',
type: 'post',
data: {
"myInput" : $('#myInput').val(),
},
success: function(response) {
if(!alert(response)) {
// do something
}
}
});
我的PHP只接受发布的输入值并对其进行操作:
if (isset($_POST["myInput"])) {
// doing something - and I want to send something back
}

只需回声并退出:
if (isset($_POST["myInput"]))
{
// doing something - and I want to send something back
exit('Success');
}
然后在你的JS中:
success: function(response) {
if (response == 'Success') {
// do something?
}
}
例如:
test.php 单页html + php帖子处理程序
<?php
// Post Handler
if (count($_POST))
{
// do something with posted data
echo "You Posted: \r\n";
print_r($_POST);
exit();
}
// dummy data outside of the post handler, which will never be sent in response
echo "Test Page";
?>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$.post('test.php', { "hello": "world" }, function(result) {
alert(result);
});
});
</script>
输出:

$.ajax({
url: 'index.php', // change your url or give conditional statement to print needed code
type: 'post',
data: {
"myInput" : $('#myInput').val(),
},
success: function(response) {
if(!alert(response)) {
// do something
}
}
});
