[{
    "cid": 11,
    "cmid": "34",
    "cdate": "2017-02-07 18:29:47",
    "postedby": "2",
    "msg": "hi salavadi",
    "myId": 22,
    "myPId": 22
},

    "cmid": "33",
    "cdate": "2017-02-07 17:40:55",

    "cmid": "32",
    "cdate": "2017-02-07 17:31:34",
    "postedby": "2",
    "msg": "how are you ?",
    "myId": 8,
    "myPId": 22
},
{
    "cid": 11,
    "cmid": "31",
    "cdate": "2017-02-07 17:29:48",
    "postedby": "2",
    "msg": "This is new message",
    "myId": 22,
    "myPId": 22
},
{
    "cid": 11,
    "cmid": "21",
    "cdate": "2017-02-03 11:39:34",
    "postedby": "2",
    "msg": "Hi Priya , This is Jayasree Salavadi",
    "myId": 22,
    "myPId": 22
}]

我有一个收件箱，我的邮件列表来自后端的相同响应。我需要根据myId和myPid将消息放在相应的html块中，如果它们都是相同的，它将在第一个块中，如果两者不相同，它将在第二个块中。我尝试过这样做，但是我只获得了第二个阻止它的所有消息。我使用ng-if条件来实现这一点，但它没有成功。

问题在于您的数据，因为所有对象 myId 和 myPId 都不同。

<强>样本

var app = angular.module ('FunStuff',[]);
app.controller ('TextController',['$scope',function($scope){
    $scope.colloborationMessages = [
      {"cid":11,"cmid":"34","cdate":"2017-02-07 18:29:47","postedby":"2","msg":"hi salavadi","myId":8,"myPId":22},
      {"cid":11,"cmid":"33","cdate":"2017-02-07 17:40:55","postedby":"2","msg":"hhhhd","myId":8,"myPId":22},
      {"cid":11,"cmid":"32","cdate":"2017-02-07 17:31:34","postedby":"2","msg":"how are you ?","myId":8,"myPId":22},
      {"cid":11,"cmid":"31","cdate":"2017-02-07 17:29:48","postedby":"2","msg":"This is new message","myId":8,"myPId":22},

    ];
}]);

</html>

ng-repeat和ng-if条件
