Edit node?

[samdoeswork]

Hi, First off Drawflow is brilliant, thank you!

I couldn't see any method to actually update the content of an existing node, e.g. to change the layout in the template. Failing this, perhaps a redraw method which doesn't clear the IDs?

The use-case is to have my application change content, e.g. the title or icon or other HTML content, then display this change to the user.

Thanks! Sam

Hello

Thanks!

There is currently no method. Maybe in the future. Since when updating the html content, the data values would also have to be updated.

You can also update the html as mentioned in: https://github.com/jerosoler/Drawflow/issues/40

You will probably also need: https://github.com/jerosoler/Drawflow/issues/43

Thank you for coming back.

I was able to work around this by removing and re-adding the nodes, then rebuilding the connections. It does require a lot of code to keep it in sync (I’m using Angular not Vue).

This library is one of my absolute favorites thank you for making it. (You should consider a pro version with support, it really is good).

Regards Sam

It's been a long time this issue is closed but facing the same issue I managed a workaround that looks a lot simpler to me. You can do this with pure JS since the node is simply a div.

What I made from an angular app is something like this (simplified):

@ViewChild('editor')
editorElementRef: ElementRef;

updateNodeHtml(nodeId: number, content: string): void {
        const nodeContainer = this.editorElementRef.nativeElement.querySelector('#node-' + nodeId + ' .drawflow_content_node');
        nodeContainer.innerHTML = content;
}

// ....
this.updateNodeHtml(1, '<h1>MyNewNodeContent</h1>');
