ajax select 不同步问题
有两个SELECT 当改变第一个SELECT 里的选项时 向服务器请求数据 加载到SELECT2里
这个功能是实现了 但是有个BUG 就是返回数据太慢 当选择完第一个SELECT后 再点SELECT2时
不能同步 通常要等个1－2秒 请问这个问题该怎么解决 新手 一枚 求大神帮帮忙
回复讨论(解决方案)
测试下后端拿数据所用的时间
每次都需要?用后端？不可以把所有select1->select2的???成json?象在前端？
如果必??求後端的，可以??，??第一?select change?，把select2?的option清掉，再?用ajax。
不?要等1-2秒?真是慢。
js封装的东西，放在服务端，js直接填充，请求一次服务端，客户端就完成填充，不用每次循环。

PHP vs. Ajax: Solutions for creating dynamically loaded content
Jun 06, 2024 pm 01:12 PM
Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

Content-Security-Policy header: Restrict the loading of malicious resources and specify the sources from which scripts and style sheets are allowed to be loaded. Validate server-side input: Validate input received from Ajax requests to prevent attackers from exploiting input vulnerabilities. Use secure Ajax libraries: Take advantage of automatic CSRF protection modules provided by libraries such as jQuery.
