IPlaceholderCreateContentOptions interface

  • Reference
Package:
@microsoft/sp-application-base

Options for the PlaceholderProvider.tryCreateContent() method.

Properties

onDispose

An optional callback that will be invoked when the PlaceholderContent object is disposed.

Property Details

onDispose

An optional callback that will be invoked when the PlaceholderContent object is disposed.

onDispose?: (placeholderContent: PlaceholderContent) => void;

Property Value

(placeholderContent: PlaceholderContent) => void

Remarks

To avoid a resource leak, use this callback to free any resources that were allocated when the placeholder content was rendered. For example, if ReactDOM.render() was used to mount a React component, then the onDispose handler might call ReactDOM.unmountComponentAtNode() to unmount it.
