php下拉框的
if(!isset($_GLOBAL_NEWS_QIKAN_TYPES)){
$_GLOBAL_NEWS_QIKAN_TYPES=array('1'=>'卷首语',
'2'=>'管理层专栏',
'3'=>'研发?技术',
'4'=>'市场速递',
'5'=>'小蜜蜂家园',
'6'=>'推荐?分享',
'7'=>'旅行?生活'
);
}
$global_news_type_inc =array();
$global_news_type_inc['1']='行业新闻';
$global_news_type_inc['2']='期刊';
?>
以上是2个数组的,然后在当我选择期刊的时候,出现上面那数组的下拉框?求大神指点,用php哦
回复讨论(解决方案)
js控制了,先把上面那个select框设置display:none 属性。然后当第二个select框选择期刊时设置它为display:block 就可以了
同意楼上说法,在select中添加onclick,调用js函数进行标签的属性处理,显示设置disply:block否则dispau:none
这用PHP真没法解决,JS可以动态处理页面,而PHP没办法,而且JS也很容易,两三句就搞定了...
楼上方法正解~
都是新手,受教了!

网上搜一下,JS多级联动,有很多例子。。。

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

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.
