在AJAX POST请求到同一页面时失败(带有示例) [英] Failed at AJAX POST request to the same page (with example)
问题描述
####### The name of this file is 'test_ajaxfn.php' #######
<?php
if($_POST['var']) {
$result = $_POST['var'];
echo $result.' is successfully passed to the same page using Ajax Post. :)';
} else {
echo 'There is no POST variable passed to the same page. :( ';
}
echo '<br> Above indicates the ajax post function \'.\' ';
?>
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#clickdiv').click(function() {
var sth = "value to send to PHP";
$.post(
'test_ajaxfn.php',
{"var":"1234567"},
function(){
alert('success');
$('#clickdiv').text('the POST variable should be posted.');
}
);
});
});
</script>
</head>
<body>
<div id="clickdiv" style="width: 50px; height: 50px; background:#CC3300; cursor:pointer;">
</div>
</body>
</html>
说明
我想将POST变量传递到同一页面并使用AJAX加载它.但是，我没有这样做.我无法使用POST方法将"var"传递给$ _POST ['var'].因此，我无法显示以下内容: 回声$结果.已使用Ajax Post成功传递到同一页面. :)';
Description
I want to pass POST variable to the same page and load it using AJAX. However, I failed to do so. I can't pass the "var" to $_POST['var'] using POST method. Hence I can't display the following: echo $result.' is successfully passed to the same page using Ajax Post. :)';
我做错了什么?
我实际上是在尝试解决这个问题: 计算Google输入地址的距离以及使用jQuery ajax.get 从MySQL Server获得的所有地址 现在，我简化了我的问题，但仍然行不通.请帮助:(

推荐答案
如果将其发布到同一页面，服务器将创建一个新进程来处理请求.您没有看到任何输出的原因是因为服务器正在看到文件的发布，旋转实例并执行php脚本，但这与您的php线程不同.将您的脚本更改为此，以查看您的成功文本.
If you post it to the same page the server creates a new process to handle the request. The reason you are not seeing any output is because the server is seeing a post to a file, spinning up an instance and executing the php script but that is different from your php thread. Change your script to this to see your success text.
<script>
$(document).ready(function() {
$('#clickdiv').click(function() {
var sth = "value to send to PHP";
$.post(
'test_ajaxfn.php',
{"var":"1234567"},
function(result){
alert(result);
$('#clickdiv').text('the POST variable should be posted.');
}
);
});
});
</script>
