推荐答案

只是因为您使用JavaScript并不意味着您的表现将会提高.首先要考虑的是重新设计您的应用程序.您是否真的需要初始页上的许多下拉菜单?可以缓存数据吗?确定性能问题在哪里.数据库查询需要更长的时间还是在渲染上花费了时间?

Just because you use JavaScript doesn''t mean your performance will increase. The first thing to consider is redesigning your application. Do you really need that many dropdowns on the initial page? Can the data be cached? Determine where the performance issues are. Do the database queries take longer or is the time spend in rendering?
