Abstract

The invention discloses a connection node control method and device for an electronic whiteboard, equipment and a storage medium. The connection node control method comprises the following steps: receiving an element selection operation, wherein the element selection operation is used for selecting a target element, and the target element is currently-displayed user input element; displaying a connection node adding button, wherein the connection node adding button is determined according to the target element; receiving a button selection operation, wherein the button selection operation is applied to the connection node adding button; displaying a connection line generated specific to the target element, and displaying a connection node on the connection line, wherein the connection nodeis editable. Through the technical scheme, the technical problem of single and inflexible element connection building manner in the prior art can be solved. The connection node can be added for the target element without being limited to the specific type of the element, the connection node can be added for any element, the application range of the connection node is enlarged, and the user experience is improved.
