crosstalk equality

I discovered this as I worked through an example of linking leaflet with DT and plotly through crosstalk (example). It seems plotly converts crosstalk keys to String and then uses exact equality match .indexOf (see lines). Thinking through how best to solve this, I came up with the following:

1. Not convert crosstalk key to string in plotly, but I am guessing there was a reason to do the conversion for plotly traces.

2. Perform match using something other than indexOf or ===. For the purposes of my example I used [].filter, but this is inefficient.

3. Expect other htmlwidget authors to also convert to string, or add both the string and non-string forms to crosstalk select.

Riproduci l’esempio crosstalk collegato in experiments/select_crosstalk.R ed esamina la logica di corrispondenza a cui si fa riferimento alla riga 739 di plotly.js. Confronta le rappresentazioni delle chiavi utilizzate da leaflet, DT e plotly, quindi stabilisci quale comportamento di corrispondenza dovrebbe essere coerente in tutto l’esempio prima di modificare qualsiasi cosa. Il lavoro è concluso quando i widget collegati selezionano in modo affidabile le stesse chiavi.
