HomeBackend DevelopmentPHP Tutorial麻烦帮小弟我看看个JAVASCRIPT的提交

麻烦帮我看看个JAVASCRIPT的提交
我主要要实现提交表单后仍然保留表单的数据,买了本《浅入深学 php》,里面 395页的代码有个 handle_f, 我照抄,但是我的PHP里没执行,为什么?我这里稍为改了一下,但是PHP 没执行handle_f,如果执行会弹出一个对话框 'hello world'






------解决方案--------------------
在什么浏览器下运行的,代码中创建XMLHttpRequest对象的方法只适用于IE5、6浏览器,兼容各浏览器的写法:

JScript code
function create_obj() {    var xmlHttp;    if (window.XMLHttpRequest) xmlHttp = new XMLHttpRequest();    else if (window.ActiveXObject) xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");    return xmlHttp;}<br><font color="#e78608">------解决方案--------------------</font><br>创建xmlHttp 对象有问题吧。 你那种是ie下的。非ie下的没加进去。改为下面这样试试:<br>xmlHttp=window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP"); <br><br><font color="#e78608">------解决方案--------------------</font><br>

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.
