Question

我正在使用electron-json-storage在电子应用中读取/写入json文件和ngElectron。电子json存储指南读取：

storage.get('foobar', function(error, data) {
  if (error) throw error;
  console.log(data);
});

使用ngElectron从角度调用该函数时，它在控制台中打印正常，但是如何让对象将其存储在范围中并稍后使用？

所以我发现了怎么做

在电子部分我不得不返回一个承诺

max = 29472
min = 18792
california = 23364
county = 24132
# county = 18792

min_label = paste0("$", format(min, big.mark = ","))
max_label = paste0("$", format(max, big.mark = ","))
california_label = paste0("$", format(california, big.mark = ","))
county_label = paste0("$", format(county, big.mark = ","))


# Define needle points
perDeg = (max - min)/180

degs = round((county - min)/perDeg, digits = 0)

deg2rad <- function(deg) { deg * pi / 180 }


# Define [x2,y2] - the needle point
  x1 = round(0.5 + (0.2 * cos(deg2rad(180-degs))), digits = 3)
  y1 = round(0.5 + (0.2* sin(deg2rad(180-degs))), digits = 3)



basePlot <- plot_ly(
  type = "pie",
  values = c(40, 10, 40, 10),
  labels = c(" ", min_label, "  ", max_label),
  rotation = 108,
  direction = "clockwise",
  hole = 0.7,
  textinfo = "label",
  textposition = "outside",
  hoverinfo = "none",
  domain = list(x = c(0, 1), y = c(0, 1)),
  # marker = list(colors = c('rgb(100, 100, 255)', 'rgb(100, 100, 255)', 'rgb(100, 100, 255)', 'rgb(100, 100, 255)')),
  showlegend = FALSE,
  sort = FALSE
)

basePlot <- add_trace(
  basePlot,
  type = "pie",
  values = c(50, 50),
  labels = c("Estimated Annual Cost of Living", " "),
  rotation = 90,
  direction = "clockwise",
  hole = 0.7,
  textinfo = "label",
  textposition = "inside",
  hoverinfo = "none",
  domain = list(x = c(0, 1), y = c(0, 1)),
  # marker = list(colors = c('rgb(255, 255, 255)', 'rgb(255, 255, 255)')),
  showlegend= FALSE
)

basePlot <- layout(
  basePlot,
  shapes = list(
    list(
      type = 'path',
      path = paste0('M 0.5 0.5 L ', x1, ' ', y1, ' Z'),
      xref = 'paper',
      yref = 'paper',
      fillcolor = 'rgb(226,210,172)'
    )
  ),
  annotations = list(
    list(
      xref = 'paper',
      yref = 'paper',
      x = 0.5,
      y = 0.4,
      showarrow = FALSE,
      text = paste0('<b>', county_label, '</b>')
    )
  )
)

角度部分

var deferred = q.defer();
storage.get('local Storage', function (error, data) {
  if (error) {
    throw error;
    deferred.reject({'status': 500, 'result': {}, 'error': error});
  }
    deferred.resolve({'status': 200, 'result': data});
  });
return deferred.promise;
