如何实现radio的显示与隐藏
从数据库中查询出一套单选题,
<?php foreach($list as $k=>$v){ ?> <ul> <li><?php echo $v['id'];?>、<?php echo $v['sub'];?></li> <li><input type="radio" name="<?php echo $k['id'];?>" value="Y" />是</li> <li><input type="radio" name="<?php echo $k['id'];?>" value="N" />否</li> <li><input type="radio" name="<?php echo $k['id'];?>" value="?" />?</li> </ul> <?php } ?>
如上代码是从数据库查询出来后显示在页面的代码,
如何实现,显示的时候只显示一个UL?
当点击radio按钮后,隐藏当前UL,显示下一个UL?
回复讨论(解决方案)
用JQuery就可以轻松实现
给每个ul一个跟$key相关的class 比如 class="ul_".$k
然后给raido一个点击事件当点击时找到其父类中class="ul_"+k的ul,将其隐藏($(".ul_"+k).hide();)并将 class="ul_"k+1的ul显示 $(".ul_"k+1).show();
另外是作为考题的话我推荐用ajax,当前dom只有一道题 选一道就传给后台再发下一道过来.

就跟普通的ajax一样,传个当前题的编号去后台取回下一道题即可 然后将取回的内容替换掉当前的内容

抱歉 那是我扯远了. 用之前说的方法就可以了.
另外,ajax在现在的网站开发中很重要.... 而且特别的简单,半个小时就能学会(JQuery的ajax).
如果有需要你可以先去搜一下先关资料看一看 有什么想法或者问题可以随时交流

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

In PHPOOP, self:: refers to the current class, parent:: refers to the parent class, static:: is used for late static binding. 1.self:: is used for static method and constant calls, but does not support late static binding. 2.parent:: is used for subclasses to call parent class methods, and private methods cannot be accessed. 3.static:: supports late static binding, suitable for inheritance and polymorphism, but may affect the readability of the code.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
