There is onChange event, but it fires also when carret moves or navigation (arrows etc) button being pushed.
I want to detect if content was changed. Basically i need to detect this only once when the very first change occur. The dumb way "compare content" may work here, but this is an anti-pattern because this task is too resources-expensive.
Since Draft uses an immutable data structure, it doesn't have to be that resource heavy – comparing references should be enough:
onChange(newEditorState) {
const currentContent = this.state.editorState.getCurrentContent()
const newContent = newEditorState.getCurrentContent()
if (currentContent !== newContent) {
// Content has changed
}
}
