Unable to set cursor in Draft.js editor
I am trying to integrate the Draft.js editor in a project.
The way I am thinking of using it, is to create a new EditorState out of my own state on every render call (the reason for this approach are related to my specific context I am not going to detail here).
What I have not succeeded is to set the cursor position in the Editor.
I have created an example on Codepen:
http://codepen.io/nutrina/pen/JKaaOo?editors=0011
In this example any character I type is prepended to the beginning of the text, instead of being inserted at the cursor position.
I have tried setting the cursor by using:
state = EditorState.acceptSelection(state, this.state.selectionState);
state = EditorState.forceSelection(state, this.state.selectionState);
but without much success.
Any help would be appreciated.
Thanks,
Gerald

@JiangYD: Thanks for the hint, I am a step further now. In my case however the keys remain unchanged. I am basically restoring the selection state of the editor on each render, but now the cursor advances 2 positions? I have updated the Codepen sample. Any ideas?

I suppose that some key press triggers multiple 'onChange' events, but your code break the events by generating a new EditorState, then something happens weirdly. 'create a new EditorState every render call' will not work I think. Maybe you could set a EditorState in component state for selection change rendering, and use your 'new state' for content change rendering.

A easy way to move the cursor around is to use Editor.forceSelection and a key binding function!
This is what your render function would look like once you have it set up
render() {
return (
<Editor
editorState={this.state.editorState}
onChange={this.onChange}
handleKeyCommand={this.handleKeyCommand}
keyBindingFn={this.myKeyBindingFn}
/>
);
}
Once you have your keybinding function, you can do something along the lines of
myKeyBindingFn = (e) => {
// on spacebar
if (e.keyCode == 32) {
const newSelection = selectionState.merge({
anchorOffset: selectionState.getAnchorOffset() + 1,
focusOffset: selectionState.getAnchorOffset() + 1,
});
const newEditorState = EditorState.forceSelection(
editorState,
newSelection,
);
this.setState({ editorState: newEditorState });
return 'space-press';
}
};
Feel free to replace anchorOffset and focusOffset with the position you would like the cursor to be in. Using a keybinding function allows better control over events
Your handleKeyCommand function would look something like this
handleKeyCommand = (command: string): DraftHandleValue => {
if (command === 'space-press') {
return 'handled';
}
return 'not-handled';
};
