弱弱的问一下,大伙平常都是肿么传递数据的呢?
比如:需要查询数据库读取数据源,整理后需要用 js 渲染做个图表
我的想法是:
索引页是个 php,用户点击有兴趣的条目然后更新索引页。可是用什么方式更新页面比较合理呢?更新需要产生对应的图表,意味着需要查询数据库。用户点击条目是用 js 响应还是通过 GET 参数刷新当前页面呢?
另外就是 js 的选择,我是战五渣,只会一些简单的 jQuery,纯 js 写页面控制什么基本就是白痴。使用其他渲染库有一些是不依赖 jQuery 的,我也想让页面轻量一些,此时应该考虑学习纯 js 还是继续加载 jQuery 呢?

- 用户点击需要更新数据,建议使用
AJAX
后台查询。图标页面对体验的要求很高。同样,第一页的数据应该也是AJAX
获取的,这样可以让用户看到绘图
的动画过程,非常炫。 - 为什么不用
jQuery
,jQuery 改良了很多 js 的特性,让 js 变的跟 PHP 一样容易上手,非常强大。一个压缩过的 jQuery 库只有几十K
,用户随随便便一张图片就200K
,没必要省这一点点体积。
这个你可以看下restapi,查询是get请求。AJAX请求后得到数据,直接在页面渲染出来。
用 JSON 构建 API 的标准指南 还没有翻译完,希望对你有帮助。
php做好json数据,js接收,ajax,页面跳转都可以,图表的话可以用一些图表库,svg的raphael, d3. jquery用就用,很多好的特性,比如ajax,页面展现,不用是给自己找麻烦

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
