Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records.

CSS Grid: Create new row when child content overflows column width

Fineuploader solves the problem of cookie loss when uploading files across subdomains

Course Introduction：In the current project, fineuploader, a pure HTML5 upload component, is used. During the development process, the upload service is placed separately under a specific subdomain. The domain set by the login cookie is under the root domain, and user login detection is performed in the back-end code. I found that I would always be redirected 302 to the non-logged-in page. After investigation, I found that it was caused by the ajax xhr request not containing cookies. After searching online, I wrote the native ajax request method: var xhr = new XMLHttpRequ...
