Value

A string.

Examples

In the following simple example we've set up an event listener to listen for the "show-modal" command:

document.body.addEventListener(
  "command",
  (event) => {
    const theAction = event.command;

    if (theAction === "show-modal") {
      console.log("Showing modal dialog");
    }
  },
  { capture: true },
);
