PHP代码
<code><?php print_r($_GET); ?> </code>
①结果只能得到一个空数组 Array()
这是为什么?求解惑
②我还想问一下name这个属性在$.get这种提交方法中到底起到什么作用

思路不对,或者说你没好好看文档,没有正确理解$.get 和 $(element).load方法。
<code>$.get('test.php', {Xiaopeng: 'text'}, function(data){ console.log(data); }); </code>
这个时候实际请求地址为test.php?Xiaopeng=text,而返回的data并不是空的,但是
<code>$("#right-table").load("test.php");</code>
这句的意思是获取test.php的返回内容并放入#right-table,此时Xiaopeng=text这个参数并不存在,所以只能得到空数组。
以下两种方式都是正解:
<code>//方法1 $.get('test.php', {Xiaopeng: 'text'}, function(data){ $("#right-table").html(data); }); //方法2 $("#right-table").load('test.php?Xiaopeng=' + $("#selectbtn1").text());</code>
建议使用Firefox(需要firebug插件)或chrome浏览器,使用相应的功能可以检测ajax请求,你会发现你原先的代码是发送了两次不同的请求,而你输出的第二次请求的返回值,同时第二次请求确实没有任何数据被发送。
<code><button class="btn btn-default selectbtn" type="button" id="selectbtn1" name="Xiaopeng">Xiaopeng</button></code>
把Xiaopeng放到class里
<code><button class="btn btn-default selectbtn Xiaopeng" type="button" id="selectbtn1">Xiaopeng</button></code>
然后这样获取
<code>$(".Xiaopeng").text()</code>
总觉得你这种实现方式很奇怪,你可以描述下你的需求再想办法解决,梳理清楚吧
alert或console.log()一下$("#selectbtn1").text(),看看有没有正确获取到值

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.
