This article mainly introduces the method of jQuery to obtain the row number and column number of the mouse click position in the table, involving jQuery event response and related operation skills for table table elements. Friends in need can refer to it. I hope it can help everyone.
Let’s take a look at the running effect first:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>www.jb51.net 鼠标点击位置行列号</title> </head> <body> <table class="mytable" border=1> <tr> <th style="width: 160px;">表头一</th> <th style="width: 160px;">表头二 </th> <th style="width: 160px;">表头三</th> <th style="width: 160px;">表头四</th> <th style="width: 160px;">表头五</th> </tr> <tr> <td>第一行第一列</td> <td>第一行第二列</td> <td>第一行第三列</td> <td>第一行第四列</td> <td>第一行第五列</td> </tr> <tr> <td>第二行第一列</td> <td>第二行第二列</td> <td>第二行第三列</td> <td>第二行第四列</td> <td>第二行第五列</td> </tr> <tr> <td>第三行第一列</td> <td>第三行第二列</td> <td>第三行第三列</td> <td>第三行第四列</td> <td>第三行第五列</td> </tr> <tr> <td>第四行第一列</td> <td>第四行第二列</td> <td>第四行第三列</td> <td>第四行第四列</td> <td>第四行第五列</td> </tr> </table> <script src="jquery-1.7.2.min.js"></script> <script> $(document).ready(function(){ $(".mytable td").click(function(){ var tdSeq = $(this).parent().find("td").index($(this)[0]); var trSeq = $(this).parent().parent().find("tr").index($(this).parent()[0]); alert("第" + (trSeq + 1) + "行,第" + (tdSeq + 1) + "列"); }); }) </script> </body> </html>Related recommendations:

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
