封装一个数组去掉重复对象的方法

export function deteleObject(obj) {
  var uniques = []
  var stringify = {}
  for (var i = 0; i < obj.length; i++) {
    var keys = Object.keys(obj[i])
    keys.sort(function(a, b) {
      return Number(a) - Number(b)
    })
    var str = ''
    for (var j = 0; j < keys.length; j++) {
      str += JSON.stringify(keys[j])
      str += JSON.stringify(obj[i][keys[j]])
    }
    if (!stringify.hasOwnProperty(str)) {
      uniques.push(obj[i])
      stringify[str] = true
    }
  }
  // eslint-disable-next-line no-self-assign
  uniques = uniques
  return uniques
}
