## add
|
||
|
||
- **详情：** 添加节点后触发，[editorService.add()](./editorServiceMethods.md#add)后触发

## history-change
|
||
|
||
- **详情：** 历史记录改变，[editorService.redo()，editorService.undo()](./editorServiceMethods.md#undo)后触发
|
||
|
||
- **事件回调函数：** `(data: MPage | MPageFragment) => void`
|
||
|
||
## change
|
||
|
||
- **详情：** DSL 发生变更后统一触发，免去分别监听 `add` / `remove` / `update` / `move-layer` / `drag-to`。在 [editorService.add()](./editorServiceMethods.md#add)、[editorService.remove()](./editorServiceMethods.md#remove)、[editorService.update()](./editorServiceMethods.md#update)、[editorService.moveLayer()](./editorServiceMethods.md#movelayer)、[editorService.dragTo()](./editorServiceMethods.md#dragto) 后触发。
|
||
|
||
回调参数 `event` 通过 `type` 区分操作类型，并携带本次变更的节点列表 `data`，每项包含变更的 `node` 及其所属的 `page`（可能为 `null`）。`move-layer` 额外携带层级偏移 `offset`，`drag-to` 额外携带目标位置 `targetIndex` / `targetParent`。
|
||
|
||
::: warning 注意
|
||
撤销 / 重做（`undo` / `redo`）内部同样会经由 `add` / `remove` / `update` 触发本事件；如需区分「用户操作」与「撤销重做」，请配合 [history-change](#history-change) 事件判断。
