setState of react不会重新呈现

Question

This code is supposed to rerender after updating to the state, but that isn't happening sadly it isn't the case

the @state get successfully updated but the rerender is missing

in data[key].data is a array of objects that gets added to array state[key]

$.get url, {t: key, o: @state[key].length, l: @state[key].length + @state.defaultAmount}, (data) =>
  if key == "allScores"
    data.allScores = data.allScores.data[@props.currentMode]
  $.each data[key].data, (i, o) =>
    @setState (state) =>
      result = {}
      result[key] = state[key].concat(o)
      result

Answer 1

If @state gets successfully updated one time, then my best bet would be that React doesn't see any change in @state values to trigger a re-render .

Inspect the values of properties of @state to see if indeed there is a change.
