HomeBackend DevelopmentPHP Tutorial关于php+mysql+ajax省市区三级联动菜单,求帮助啊

哎,我又来了。这次是关于省市区三级联动菜单的问题。我在网上找了很多这样的代码,但是大部分都是把数据放到js里面的。老板说不行,要连接数据库的,然后我又在CSDN论坛上找了一个带数据库的。但是不好用啊,后面老板给了我数据库,是三个表,省市区各占一个,省市区个有一个id,市和区有父id,市的父id就是省的ID,区的父id就是市id。然后用ajax作出三级联动的效果,他说这样简单,可是我不会ajax啊。不知道大神可不可以帮帮忙啊。昨天就因为这个是加班到8点多啊,大学毕业以来第一次加班到这么晚啊......这个本是昨天的活,今天还有今天的活,不能再拖啊了啊。拜托了。

额,我在网上找了一个纯js的,把他放在静态页面就还用。但是放到我的项目里面就不好用了。不显示数据。用火狐调试显示 还有 ,area.js,location.js这两个文件每个里面都声明了一个函数function showLocation(province , city , town)和
function Location() 
我在百度上查说
$(document).ready(function() {
的意思是:“页面加载成功后,页面内的所有链接在“点击”事件的时候,都加载那个函数”我的项目是在cms基础上进行二次开发,是不是和原有的js冲突了。本人js小白,求指导.....

我用上面那个老兄邮箱发给我的代码,出现的问题是查询出来的省的数据都是“???”但是数据库编码是UTF8,我php的编码也是UTF8,不知道为啥会出现这种问题。还有就是我代码放到我的项目里,就只有省里面会有数据,但是市和区里面都查询不到数据,不知道为啥,

原生 js 代码不超过 20 行

哎,主要是js的一点都不会啊,php也是半吊子。求大神给个js代码被,网上弄的都是一放到我的项目里就不好用了。关于php的给我个思路我自己弄也可以啊。我的数据库的结构就是省市区分三个表,每个表都有一个id,一个名字。市和区各有一个父id,市的父id就是省的id,区的父id就是市的id

是的,当然你要有,且路径正确

再问你个事情呗,就是我把你给的三段代码都放在了html里面,然后也面上放php代码的地放就把省里面的所有数据都循环出来了,

我看php的代码最后把数据echo了一下,所以页面上会出现省的数据。但是怎么给她放到下拉菜单里面的。还有我这个网站使用cms做的,是不是就不用加载jquery了。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

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.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP vs. Python: Use Cases and ApplicationsPHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP: An Introduction to the Server-Side Scripting LanguagePHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AM

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP and the Web: Exploring its Long-Term ImpactPHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AM

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
