Use the ":even" selector with the css() method to set the color of the even-numbered row element. The syntax is "$(":even").css("color attribute","color value ")".

How to use jQuery to achieve interlaced color changing effect
1. Set the color of row elements with odd index numbers
:odd selector selects items with odd index numbers Each element of the number (for example: 1, 3, 5, etc.).
Index values start from 0, the first element is even (0), the second element is odd (1), and so on.
The most common usage: used with other selectors to select every odd-numbered element in the specified combination.
The syntax is:
$(":odd")
css() method sets or returns one or more style attributes of the selected element.
2. Set the color of row elements with even index numbers.
: The even selector selects each element with an even index number (for example: 0, 2, 4 etc).
Index values start from 0, the first element is even (0), the second element is odd (1), and so on.
The most common usage: used with other selectors to select every even-numbered element in the specified combination
The syntax is;
$(":even")
The example is as follows:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script src="js/jquery.min.js"> </script> <script> $(document).ready(function(){ $("tr:odd").css("background-color","yellow"); $("tr:even").css("background-color","pink"); }); </script> </head> <body> <table border="1"> <tr> <th>姓名</th> <th>年龄</th> </tr> <tr> <td>张三</td> <td>123131</td> </tr> <tr> <td>李四</td> <td>456464</td> </tr> <tr> <td>王五</td> <td>78979879</td> </tr> <tr> <td>赵钱</td> <td>147741</td> </tr> <tr> <td>周吴</td> <td>852258</td> </tr> </table> </body> </html>

React performance bottlenecks are mainly caused by inefficient rendering, unnecessary re-rendering and calculation of component internal heavy weight. 1) Use ReactDevTools to locate slow components and apply React.memo optimization. 2) Optimize useEffect to ensure that it only runs when necessary. 3) Use useMemo and useCallback for memory processing. 4) Split the large component into small components. 5) For big data lists, use virtual scrolling technology to optimize rendering. Through these methods, the performance of React applications can be significantly improved.

Someone might look for alternatives to React because of performance issues, learning curves, or exploring different UI development methods. 1) Vue.js is praised for its ease of integration and mild learning curve, suitable for small and large applications. 2) Angular is developed by Google and is suitable for large applications, with a powerful type system and dependency injection. 3) Svelte provides excellent performance and simplicity by compiling it into efficient JavaScript at build time, but its ecosystem is still growing. When choosing alternatives, they should be determined based on project needs, team experience and project size.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
