Abstract:
Disclosed is a viewport display method and display apparatus. The method includes: receiving a user operation for continuously moving out of a viewport by causing a selector position on a boundary element of the viewport; determining first element numbers that correspond to elements in a virtual list in which the boundary element is located according to the user operation; determining second element numbers that correspond to to-be-displayed elements on the virtual list according to the first element numbers and the direction of the selector moving out of the viewport; sorting the second element numbers; updating a virtual list rendered by the elements that correspond to the first element numbers by utilizing the sorted second element numbers; and controlling total elements in the updated virtual list to be displayed in the viewport.
