后台upload_deal.php
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> if($_REQUEST['hour']==1) { echo "true"; } else { echo "false"; }
想实现将hour提交到后台判断,再根据返回值,true正确则提交表单、跳转,false错误则不提交表单、不跳转、给出提示。但是这个代码在firefox和谷歌等非ie内核的浏览器没有问题,但是使用ie(我这是9)就全部都跳转了。尝试加上回调函数的状态判断onreadystatechange,但是所有浏览器就都不执行了,一过onreadystatechange就直接到最后的return了。

------解决方案--------------------
搜了搜,javascript没有trim()方法吧? resTest=resTest.trim();

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
