delete-assignment

PRO

The functionality is available in PRO Edition only

Description​

Fires when deleting a resource assignment

Usage​

"delete-assignment": ({
  id: string | number,
}) => boolean | void;
info

For handling the actions you can use the Event Bus methods. Returning false from the action handler will block the action (see Preventing actions)

Parameters​

The callback of the delete-assignment action can take an object with the following parameters:

  • id - (required) the ID of the assignment to be deleted

Example​

Use the api.exec method to trigger the action:

<script>
  import { getData } from "./common/data";
  import { Gantt } from "@svar-ui/svelte-gantt";

  const data = getData();
  let api = $state();

  function init(ganttApi) {
    api = ganttApi;
  }

  function removeAssignment() {
    api.exec("delete-assignment", { id: 1 });
  }
</script>

<Gantt
  tasks={data.tasks}
  links={data.links}
  scales={data.scales}
  {init}
/>

Prevent deleting an assignment​

You can intercept the action and return false to block it:

api.intercept("delete-assignment", ev => {
  if (!allowDelete) return false; // prevents deletion
});
