php动态数据点击表头部排序问题
想要实现点击列头进行排序,table中的内容为动态数据,表头输出固定,内容只有一行(一个tr)循环输出,网上找到的代码都是对固定数据进行排序的。求一份动态数据排序的代码。最好能写一小点代码方便理解。
回复讨论(解决方案)
只有一行,怎么展示排序的结果?
<table> <tr> <td onclick="sortData()" data-sort='asc' class='head'>表头</td> </tr> <tr class='data'> <td>数据</td> </tr></table>
1其实很简单,要是不考虑数据库负载,可你可以这样 给你个简单demo.
你可以用sortData()的js触发事件 ajax移步去请求数据库重新按你想要的顺序排列
注意后边的data-sort属性 这是纪录你当前排序的顺序
function sortData(){ var sortString = $(".head").attr('data-sort'); //获取你的查询条件 和sortString //ajax请求 $(".data").remove();//把以前的数据移除掉 //拼接数据 替换 }
原理就是异步请求查询数据后 凭借标签 替换现有页面标签
2.如果不想查询数据库 那么刻意根据data class 把所有的数据标签找到 然后用js进行排序后替换掉页面标签
无论怎么实现 你都要替换页面原排序的标签元素 这个是主要的
<table> <tr> <td onclick="sortData()" data-sort='asc' class='head'>表头</td> </tr> <tr class='data'> <td>数据</td> </tr></table>

嗯,谢谢提醒,我已经实现了,给表头添加了a标签,给定触发事件换参数查询数据库重新加载页面实现的。

Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

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 is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.
