javascript - 获取总销售额

Question

我创建了一个函数，它将返回一个没有重复分支的对象以及每个分支的总销售额。

    var salesPersons = [
        {"name": {"first": "Aleen", "last" :"Atkins"}, "sales" : "$2314", "branch": "Austin, TX"},
        {"name": {"first": "Alvaro", "last" :"Angelos"}, "sales" : "$1668", "branch": "New York City, NY"},
        {"name": {"first": "Denese", "last" :"Dossett"}, "sales" : "$9248", "branch": "Austin, TX"},
        {"name": {"first": "Douglas", "last" :"Denney"}, "sales" : "$5058", "branch": "New York City, NY"},
        {"name": {"first": "Earline", "last" :"Erickson"}, "sales" : "$18876", "branch": "New York City, NY"},
        {"name": {"first": "Herman", "last" :"Hazell"}, "sales" : "$2746", "branch": "New York City, NY"},
        {"name": {"first": "Homer", "last" :"Hirth"}, "sales" : "$474", "branch": "Orlando, FL"},
        {"name": {"first": "Hwa", "last" :"Heidt"}, "sales" : "$9607", "branch": "San Francisco, CA"},
        {"name": {"first": "Hyon", "last" :"Hampshire"}, "sales" : "$13598", "branch": "New York City, NY"},
        {"name": {"first": "Issac", "last" :"Ingerson"}, "sales" : "$5225", "branch": "Austin, TX"},
        {"name": {"first": "Jeraldine", "last" :"Joplin"}, "sales" : "$2891", "branch": "New York City, NY"},
        {"name": {"first": "Jin", "last" :"Jeffrey"}, "sales" : "$14402", "branch": "Austin, TX"},
        {"name": {"first": "Joleen", "last" :"Jolin"}, "sales" : "$15736", "branch": "Austin, TX"},
        {"name": {"first": "Jude", "last" :"Jarrett"}, "sales" : "$7557", "branch": "San Francisco, CA"},
        {"name": {"first": "Magda", "last" :"Mireles"}, "sales" : "$1498", "branch": "Austin, TX"},
        {"name": {"first": "Mistie", "last" :"Montealegre"}, "sales" : "$6920", "branch": "New York City, NY"},
        {"name": {"first": "Nancy", "last" :"Napoli"}, "sales" : "$5255", "branch": "New York City, NY"},
        {"name": {"first": "Regine", "last" :"Rohrbaugh"}, "sales" : "$7881", "branch": "Orlando, FL"},
        {"name": {"first": "Rolando", "last" :"Riebel"}, "sales" : "$8573", "branch": "San Francisco, CA"},
        {"name": {"first": "Scarlett", "last" :"Stagg"}, "sales" : "$7126", "branch": "Orlando, FL"},
        {"name": {"first": "Sherron", "last" :"Strawn"}, "sales" : "$8848", "branch": "New York City, NY"},
        {"name": {"first": "Susan", "last" :"Shilling"}, "sales" : "$8542", "branch": "Seattle, WA"},
        {"name": {"first": "Tama", "last" :"Tworek"}, "sales" : "$9200", "branch": "Seattle, WA"},
        {"name": {"first": "Tonisha", "last" :"Taunton"}, "sales" : "$5219", "branch": "Orlando, FL"},
        {"name": {"first": "Vergie", "last" :"Villescas"}, "sales" : "$8712", "branch": "New York City, NY"}
    ];

    function convertSalesToInt(person){
      var salesInt = person.sales.slice(1);
      return parseInt(salesInt, 10);
    }

    function salesPerBranch(salesPersons){
    var myObj = {};
    var uniq = [];
    var total = 0;

    for(var i = 0; i < salesPersons.length; i++){
      var splitTeam = salesPersons[i].branch;
      if(uniq.indexOf(salesPersons) < 0){
        myObj[salesPersons] = total+= convertSalesToInt(salesPersons[i]);
      }
    }

    return myObj;


    }

    console.log(salesPerBranch(salesPersons));
    /* { 'Austin, TX': 110898,
  'New York City, NY': 187174,
  'Orlando, FL': 178462,
  'San Francisco, CA': 139527,
  'Seattle, WA': 173243 } */

答案应该是这样的:

{
    'Austin, TX': 48423,
    'New York City, NY': 74572,
    'Orlando, FL': 20700,
    'San Francisco, CA': 25737,
    'Seattle, WA': 17742
}

我现在唯一遇到困难的部分是我添加每个分支机构的总销售额的部分。现在它没有拉动适当的数量。这部分负责:

if(uniq.indexOf(salesPersons) < 0){
        myObj[salesPersons] = total+= convertSalesToInt(salesPersons[i]);
      }

有人知道我的错误是什么以及如何解决它吗？

谢谢!

];

function convertSalesToInt(person){
  var salesInt = person.sales.slice(1);
  return parseInt(salesInt, 10);
}

function salesPerBranch(salesPersons){
  var myObj = {};

  for(var i = 0; i < salesPersons.length; i++){
    var splitTeam = salesPersons[i].branch;
    myObj[splitTeam] = myObj[splitTeam] ? myObj[splitTeam]: 0;
    myObj[splitTeam] += convertSalesToInt(salesPersons[i]);
  }

  return myObj;
}

console.log(salesPerBranch(salesPersons));

您需要检查是否没有销售计数数据，然后将其设置为零，如果有，则添加到它。
