我用$.post提交表单,如果登录成功直接将信息保存到session,如果失败返回失败原因。
我是在模态框上写的表单,把失败原因显示在模态框上。但是返回后会自动刷新并关闭模态框。
如果我在$.post完成后return false;则不会关闭模态框且显示正常。 但是如果登录正确了也会return false;
要如何解决

如果你明确你在js中没有执行reload操作,然而点击提交按钮却会刷新页面的情况是:
当你点击提交的时候,其实完成了两个动作,一个是你写的ajax提交数据,一个是form表单的自动提交,而且你在form中的action是为空的吧,就提交到当前页面,也就是刷新咯
所以你
<code>click(function(){ //ajax提交 $.post(); return false; }) </code>
在你return false时就阻止了form的提交,这个是可以加上的。
但是你说的登录正常也是return false你不要把他用作回调结果吗,当做一个动作,就ok了,
看是否返回成功,直接看你的ajax返回值就Ok啦,然后如果需要根据是否登录成功来进行下面的操作的时候,就把动作写在ajax的回调中
你把服务器端的代码也发上来啊
ajax发送一个请求到服务器,服务器可以return一个json结果,同样也可以重定向刷新页面,这个取决于服务器端的代码实现,lz应该先去服务器端进行排查

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.
