lodash用_.get（）深深偷看

Question

我有这样的数据结构

var data = {
  'app.state1': {
    some: {...},
    sequences: [
      {...},
      {...},
      {...}
    ]
  },
  'app.state2': {
    some: {...},
    sequences: [
      {...},
      {...}
    ]
  }
};

我希望在sequences

的索引0获取data['app.state1']

我试图像这样实现它

var seq = _.get(data, 
   'data[' + currentState + '].sequences[' + currentSequence +']');

或者像这样

var seq = _.get(data, 
   'data[\'' + currentState + '\'].sequences[' + currentSequence +']');

两者都不起作用......我相信currentState的问题是内部的点（app.state1或app.state1.substate2例如）。有什么想法吗？

Answer 1

你结合得多，检查一下：

var seq = _.get(data, [currentState, 'sequences', currentSequence]);
