回复讨论(解决方案)
所有的input加disabled.
还有其它的checkbox text 等都一个一个加?
有没有更好的方法?
可以遍历表单的元素 就不用每一个都去写
1?的方法不?
这个就只能这样了
给文本框加上只读属性 readonly
比较简单的方法是在表单上面加一个透明的层
disabled了 如在表单中,数据不能传递
如非要传递,还不能修改,用readonly
我来总结一下
比较先进的方法是在body体内加个div,设置其style的index值最大,比如9999,结合css和div技术可以实现当前页面上浮一个透明层,这样用户就不能操作了。
比较彻底的方法,是遍历所有表单元素将其disabled,这个用jquery一个方法就能搞定。至于楼上兄弟提出的readonly属性,只对文本框、文本区域有效,对下拉框等表单元素无效。
多谢大家,能提供 9楼的二种方法的二个例子吗,

我来介绍下用jquery设置disabled的属性吧。
html页面上引入jquery库文件就不多说了
设置的语句如下:
<script type="text/javascript>$(function(){ $("input").attr("disabled",true);});</script>
当然了,如果你不用jquery,原生态javascript可以这么写:
document.getElementsByTagName("input").disabled = true;
过来看下 顺便学习一下经验!
其实最简洁实用的方法就是禁用保存或提交按钮就好了
12楼的解答非常正确

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
