JavaScript/jQuery Gantt - resourceAssignments
Type:
Default Value: null
Resource assignments define relationship between tasks and resources.
Use the dataSource property to bind the UI component to a data source, which contains resource assignments. If the field names in your data source differ from the 'id', 'resourceId' and 'taskId' default names, use the keyExpr, resourceIdExpr and/or taskIdExpr properties to map data fields.
