Tạo Accordion động sử dụng jQuery trong Asp.net
(Create Dynamic jquery Accordion in Asp.net) – Có nhiều cách để tạo Accordion động mà thủ thuật lập trình đã giới thiệu với các bạn như: sử dụng Bootstrap, sử dụng AjaxControlToolkit. Ngoài 2 cách trên, hôm nay thủ thuật lập trình sẽ giới thiệu với các bạn thêm 1 cách nữa để có thể tạo Accordion động, đó là sử dụng thư viện jQuery. Với ví dụ dưới đây, tên các khách hàng sẽ được hiển thị và khi kích vào tên thông tin chi tiết sẽ được hiển thị.
