Question

錯了鑰匙我都有數據：

[Object, Object, Object] 
    0: Object 
    $$hashKey: "007" 
    amount: "123111" 
    name: "test" 
    number: "5" 
    position: "ttt" 
    1: Object 
    $$hashKey: "006" 
    amount: "123111" 
    name: "test4" 
    number: "4" 
    position: "поз" 
    2: Object 
    $$hashKey: "005" 
    amount: "34555" 
    name: "еее" 
    number: "1" 
    position: "вапвап" 

，我在HTML中有中繼器：

<tr ng-repeat="(key, player) in players | orderBy:'number'"> 
    <td>{{key}} - {{player.number}}</td> 
    <td>{{player.name}}</td> 
    <td>{{player.position}}</td> 
    <td>{{player.amount}}</td> 
    <td> 
     <button ng-click="edit(key)" class="btn btn-primary"><span class="glyphicon glyphicon-edit"></span></button> 
     <button ng-click="delete(key)" class="btn btn-danger"><span class="glyphicon glyphicon-floppy-remove"></span></button> 
    </td> 
</tr> 

我需要從中繼當前元素的數據拿到鑰匙，但關鍵是我得到了訂單的價值。

0 - 1 еее вапвап 34555  
1 - 4 test4 поз 123111  
2 - 5 test ttt 123111 

，但我需要：

2 - 1 еее вапвап 34555  
1 - 4 test4 поз 123111  
0 - 5 test ttt 123111 

Answer 1

你不能。列表值的順序發生變化，這意味着您在使用ng-repeat觀看之前爲每個索引獲取新值。您應該將索引設置爲玩家的屬性。然後使用該屬性。

for(var i in players) { 
    players[i].index = i; 
} 

Answer 2

$scope.getRealId = function(hashKey) { 
    for (var i in $scope.players) { 
     if ($scope.players[i].$$hashKey === hashKey) { 
      return i; 
     } 
    } 
}; 

和NG-重複內：

{{getRealId(player.$$hashKey)}} 

或

<button ng-click="edit(getRealId(player.$$hashKey))" class="btn btn-primary"><span class="glyphicon glyphicon-edit"></span></button>
