JavaScript 数据由驼峰结构转下划线结构

// 数据转换
function recursionFunc (data) {
  if (data && typeof (data) == 'object') {
    var obj
    if (Array.isArray(data)) {
      obj = []
      for (var item of data) {
        obj.push(recursionFunc(item))
      }
    } else {
      obj = {}
      for (var key in data) {
        var newKey = changeKey(key) // 字符串转换
        obj[newKey] = recursionFunc(data[key])
      }
    }
    return obj
  } else {
    return data
  }
}

// 字符串转换
function changeKey (str) {
  var arr = [...str]
  var arrCopy = [...str]
  var index = 0
  var length = arrCopy.length
  for (var i of arrCopy) {
    var front = index - 1 >= 0 ? arrCopy[index - 1].charCodeAt(0) : null
    var behind = index + 1 < length ? arrCopy[index + 1].charCodeAt(0) : null
    var num = i.charCodeAt(0)

    if (num >= 65 && num <= 90) {
      if (front && (front >= 97 && front <= 122 || behind && behind >= 97 && behind <= 122)) {
        arr[index] = '_' + arr[index].toLowerCase()
      } else {
        arr[index] = arr[index].toLowerCase()
      }
    }
    index++
  }
  return arr.join('')
}

使用：var result = recursionFunc(data)
