How to disable connector selection in JavaScript Diagram?

This article explains how to disable connector selection in JavaScript Diagram. In JavaScript Diagrams, connectors are used to create links between nodes or ports to represent the relationships between them. A connector can be created by defining the source and target points of the connector. To disable connector selection, you can remove the selection constraints from the default connector constraints. This prevents users from selecting the connector when interacting with the diagram.

// Initializes the connectors for the diagram
var connectors = [
 {
   id: 'connector1',
   sourceID: 'node1',
   sourcePortID: 'port2',
   targetPortID: 'port4',
   targetID: 'node3',
   type: 'Orthogonal',
   constraints:
     ej.diagrams.ConnectorConstraints.Default &
     ~ej.diagrams.ConnectorConstraints.Select,
   annotations: [{ constraints: ej.diagrams.AnnotationConstraints.ReadOnly }],
 },
];

// Initialize the diagram
diagram = new ej.diagrams.Diagram({
 width: '100%',
 height: '645px',
 nodes: nodes,
 connectors: connectors,
});
diagram.appendTo('#diagram');
