Question

我有一个函数可以进行两次ajax调用。一次调用返回包含其他对象的Object;另一个是对象数组。

//Object 1 
1: {
    table_info: {
      id: "1",
      event_id: "JHDQ",
      name: "test",
      cap: "10",
      seating: "OPEN",
      updated: "2017-02-12 16:34:01",
      position_x: "10",
      position_y: "99",
      count: 2
    },
    assignments: [{
        participant_id: "99154143",
        seat_number: "2"
      },
      {
        participant_id: "99154149",
        seat_number: "3"
      }
    ]
  },
  3: {
    table_info: {
      id: "3",
      event_id: "JHDQ",
      name: "test",
      cap: "10",
      seating: "OPEN",
      updated: "2017-02-12 16:17:00",
      position_x: "10",
      position_y: "99",
      count: 2
    },
    assignments: [{
        participant_id: "99154146",
        seat_number: "2"
      },
      {
        participant_id: "99155361",
        seat_number: "3"
      }
    ]
  }

//Object 2
{
  id: "99155361",
  first_name: "gary",
  last_name: "banker",
  email: "test2",
  company: null
}, {
  id: "99155365",
  first_name: "tim",
  last_name: "banker",
  email: "test1",
  company: null
}

我需要遍历对象1才能到达赋值数组。对于赋值数组中的每个索引，我需要将participant_id与对象2中的每个ID进行比较。如果有匹配，请提醒（＆＃34;匹配＆＃34;），否则，提醒（＆＃34;不匹配＆＃ 34）。请让我知道我需要做些什么才能实现这个目标？

Answer 1

//object with assignments
var objects = {};
//array of assignmenents
var objArray =  [];
//foreach key on first object find assignements
Object.keys(objects).forEach(function(key) {
  var assignments = objects[key].assignments || [];
  //foreach assignment id match against id in the other array
  assignments.forEach(function(assignment){ 
    objArray.forEach(function(oAssignment){
      if(assignment['participant_id'] === oAssignment.id){
        alert('Found match for: ' + assignment['participant_id'] );
      }
    });
  });
});

遍历对象以与其他对象进行比较
