遍歷對象與其他對象進行比較

-1

我有一個函數可以進行兩次ajax調用。一次調用返回一個包含其他對象的Object;另一個是一組對象。遍歷對象與其他對象進行比較

//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 
}

我需要遍歷對象1才能到達賦值數組。對於assignments數組中的每個索引，我需要將participant_id與對象2中的每個ID進行比較。如果匹配，則爲alert（「match」），否則爲alert（「no match」）。請讓我知道我爲了達到這個目標需要做什麼？

你可以包括'javascript'，你已經試過在問題？ – guest271314

您需要遍歷每個返回的值。你可以在object1上使用'forEach'。在'forEach'中，你需要遍歷任務列表，可能使用另一個'forEach'或者'for'。在該循環中，循環訪問object2並在if/else語句中使用'==='在當前賦值'participant_id'和當前object2'id'之間進行簡單的字符串比較。如果找到匹配的警報，則返回警報。 – haxxxton

//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']); 
     } 
    }); 
    }); 
});

是否有任何理由爲什麼你選擇Object.keys（objects）.forEach（function（key）'而不是'for（var key in objects）'？ –

否。事實上，我之前使用過，但我認爲Object。鍵讀得更好，只是個人喜好。 – VinPro
