关于那些购物网站
那些购物网站有那种选不同颜色不同size就价钱不同然后显示出来,
用了什么技术?
是ajax吗?
php新手
谢谢
------解决方案--------------------
有些是Ajax异步读取的。。
当点击不同的颜色和尺寸时进行Ajax交互读取新价格。
还有一种是页面加载完成后就载入了全部不同组合的价格。然后选择与页面相匹配的那种商品显示其价格。
当点击不同颜色和尺寸时，切换到你选择的那种商品的价格。
<br />{<br />"qikequanmai":{"name":"奇客花生香酥全麦饼 110克/盒 6盒组合","price":"￥99.00元"},<br />"qikecongxiang":{"name":"奇客葱香全麦饼 110克/盒 6盒组合","price":"￥99.00元"}<br />}<br />------解决方案--------------------
楼上正解，看你的数据量，如果仅仅几种颜色+尺码同时用户可能来回点，用本地js搞定，不能用ajax占连接，像全国地区数据就ajax吧

ajax给服务器增加压力本来就不对了，
居然想刷新页面，压力不就更大。
虽然增加一点ajax请求可能看不出来（只要服务器够强就没事）
但做技术的凡事要尽量用最好的解决方案，要有精益求精的工匠精神，这是态度问题！
而且一般精益求精的时候对自己的技术是有帮助的，比如用js做刚好能练习下js。
但是要改很多div的话我觉得是设计问题。
就淘宝商品页面来说，一个商品一般就改个当前颜色的文字和商品图片就行了
介绍页面就不用改了，全部介绍一下。没有改个颜色还要改介绍文字的。
而更新个当前颜色、尺寸，图片，价格 最多5个地方会多吗？
封装个方法，然后把当前颜色大小传进去统一更新页面就行了
PHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AMPHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AMPHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.
The Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AMThe future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
When would you use a trait versus an abstract class or interface in PHP?Apr 10, 2025 am 09:39 AMIn PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.
What is a Dependency Injection Container (DIC) and why use one in PHP?Apr 10, 2025 am 09:38 AMDependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.
Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Apr 10, 2025 am 09:37 AMSplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.
How does PHP handle file uploads securely?Apr 10, 2025 am 09:37 AMPHP 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.
What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?Apr 10, 2025 am 09:33 AMIn JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
