基于alibaba-designable源码二次封装的表单设计器。

import { KeyCode, Shortcut, TreeNode } from '../models';

/**
 * 快捷删除，快捷复制粘贴
 */

export const DeleteNodes = new Shortcut({
  codes: [[KeyCode.Backspace], [KeyCode.Delete]],
  handler(context) {
    const operation = context?.workspace.operation;
    if (operation) {
      TreeNode.remove(operation.selection.selectedNodes);
    }
  }
});
const Clipboard = {
  nodes: []
};
export const CopyNodes = new Shortcut({
  codes: [[KeyCode.Meta, KeyCode.C], [KeyCode.Control, KeyCode.C]],
  handler(context) {
    const operation = context?.workspace.operation;
    if (operation) {
      Clipboard.nodes = operation.selection.selectedNodes;
    }
  }
});
export const PasteNodes = new Shortcut({
  codes: [[KeyCode.Meta, KeyCode.V], [KeyCode.Control, KeyCode.V]],
  handler(context) {
    const operation = context?.workspace.operation;
    if (operation) {
