RangeRef
RangeRef objects keep a specific range in a document synced over time as new operations are applied to the editor. It is created using the Editor.rangeRef method. You can access their property current at any time for the up-to-date Range value. When you no longer need to track this location, call unref() to free the resources. The affinity refers to the direction the RangeRef will go when a user inserts content at the edges of the Range. inward means that the Range tends to stay the same size when content is inserted at its edges, and outward means that the Range tends to grow when content is inserted at its edges.interface RangeRef {
current: Range | null
affinity: 'forward' | 'backward' | 'outward' | 'inward' | null
unref(): Range | null
}
For example:
const selectionRef = Editor.rangeRef(editor, editor.selection, {
affinity: 'inward',
})
// Allow the user to do stuff which might change the selection
Transforms.unwrapNodes(editor)
Transforms.select(editor, selectionRef.unRef())
Call this when you no longer need to sync this range. It also returns the current value.
Transform the range refs current value by an
op. The editor calls this as needed, so normally you won't need to.Last modified 4mo ago
