php文件
<?php $con = mysql_connect("localhost","root","w123456"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("peixunrecord", $con); mysql_query("set names 'utf8'"); $bumen = $_POST['bumen']; $keduimokuai = $_POST['keduimokuai']; $xingming = $_POST['xingming']; $peixunshijian = $_POST['peixunshijian']; $keti = $_POST['keti']; $xinde = $_POST['xinde']; $sql="INSERT INTO record (bumen,keduimokuai,xingming,peixunshijian,keti,xinde) VALUES ('$bumen','$keduimokuai','$xingming','$peixunshijian','$keti','$xinde')"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } echo "<script>alert('提交成功!');</script>";?>
我现在写了一个jquery打算每次提交后清除姓名中的内容代码如下
$(function() { $(':input','#recordform') .not(':button, :submit, :reset, :hidden') .val('') })
请问怎么使用啊 加在哪个都无法实现提交后清除姓名
求助!

不知道你的 js 函数 checkpost 是怎么写的
如果 checkpost 仅仅是返回一个 true,那么表单提交后将产生新的 document。并不存在修改原表单元素的事情(也修改不到)
在 checkpost 中执行 submit 也是一样
如果 checkpost 是通过 ajax 完成提交的,那么你需要的动作应写在 $.post 的回调函数中
function checkpost() { if(recordform.bumen.value==""){alert("请选择部门!"); recordform.bumen.focus(); return false; } if(recordform.keduimokuai.value==""){alert("请选择科队/模块!"); recordform.keduimokuai.focus(); return false; } if(recordform.keti.value==""){alert("请选择课题!"); recordform.keti.focus(); return false; } }
这是checkpost方法
function checkpost() { if(recordform.bumen.value==""){alert("请选择部门!"); recordform.bumen.focus(); return false; } if(recordform.keduimokuai.value==""){alert("请选择科队/模块!"); recordform.keduimokuai.focus(); return false; } if(recordform.keti.value==""){alert("请选择课题!"); recordform.keti.focus(); return false; } }
这是checkpost
那么你的表单是正常提交的,提交后将产生新的 document 需点击浏览器后退按钮才会回到提交前的表单
因此并没有修改的可能性
那我要怎么修改(或重新写)才能达到预期效果呢?
使用ajax请求

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
