怎么用一个ajax把一个div里的数据提交给后台的php执行呢,就是保存?
写一个jQuery的示例吧,假设你要获取<div id="content">123</div>
的内容并保存。
<code>var t = $('#content').text(); $.post('up.php', {text:t}, function(d) { /*发送成功后执行*/ }); </code>
up.php
页面只要向正常的表单一样用$_POST['text']
就可以获取到传递过去的参数了。
原生js中,需要拼接字符串 like this
// createRequest()是自己写的兼容函数 request = new createRequest(); var data = 'content='+div.innerHTML+'&id='+num; request.open("POST",url,true); request.setRequestHeader("Content-Type","text/plain"); request.send(data); request.onreadystatechange=callback; // 这个函数特意从以前写过的程序里拿出来,应该是以前从红皮书里抄来的QAQ忘记了 function createRequest() { try { request = new XMLHttpRequest(); } catch (tryMS) { try { request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (otherMS) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (failed) { request = null; } } } return request; }
补充一下一楼的,人家不一定要text啊
<code>var t = $('#content').text(); //或者 var t=$('#content').html(); $.post('up.php', {text:t}, function(d) { /*发送成功后执行*/ }); </code>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
