Implementation of 'left menu, right content' page effect based on Ajax+div

Effect demonstration:

①Default page (index.jsp):

②: After clicking the User List option under the User Management label on the left, the content of the default page on the right is updated to the content of the user list page (userList.jsp):

③: In the same way, click Product Management, Order Management under the tags Product List, Order List, the content on the right side will be refreshed accordingly to the content of the product list page (productList.jsp) and order list page (recordList.jsp)

In this way, Ajax+div is used to realize the menu selection on the left and the display effect of the content on the right. Let’s take a look at the specific implementation process

1:

The sample program for the entire demonstration includes the default page (index.jsp), user list page (userList.jsp), product list page (productList.jsp), and order management page (recordList.jsp)

Used Bootstrap framework and FontAwesome icons (no way, bootstrap comes with too few icons o(╯□╰)o), please see the official website for how to use these two products, they are relatively simple

Let’s take a look at the code of index.jsp first. I have basically commented it in detail:
