AngularJS ng-repeat在带有过滤器的数组上

Question

I have a JS array of objects.

$scope.users = [{
    "name": "alice",
    "city": "london",
    "wards": [{
            "id": 1,
            "number": 24
        },
        {
            "id": 2,
            "number": 25
        },
        {
            "id": 3,
            "number": 26
        }
    ]
},
{
    "name": "bob",
    "city": "london",
    "wards": [{
            "id": 1,
            "number": 24
        },
        {
            "id": 2,
            "number": 25
        },
        {
            "id": 4,
            "number": 27
        }
    ]
}
]

I have a ng-repeat="user in users | filter: searchUser

Here searchUser can contain name , city and ward number . Now the search is working fine for name and city but not for the sub array of objects wards to search for ward number .

Is there an angularJS way with which I could achieve this?

No. You need to write your own custom filter.

Here is a sample jsfiddle, tested with input search

alice, bob, london, 26, 27

If you want exact match, then change -1 to 0

app.filter('myFilter', function(){
    return function(users, search){
    if(!search) return users;
    if(!users || !users.length) return users;
    searchInLower = search.toString().toLowerCase();
    users = users.filter(function(user){
        matches = false;
        if(user.name){
        usernameInLower = user.name.toString().toLowerCase();
        matches = matches || usernameInLower.indexOf(searchInLower) !== -1;
      }
      if(user.city){
        cityInLower = user.city.toString().toLowerCase();
        matches = matches || cityInLower.indexOf(searchInLower) !== -1;
      }
      if(user.wards && user.wards.length && !matches){
        for(var i = 0; i < user.wards.length; i++){
         ward = user.wards[i];
         for(var key in ward){
           objectKeyValueInLower = ward[key].toString().toLowerCase();
           matches = matches || objectKeyValueInLower.indexOf(searchInLower) !== -1;
         }
        }
      }

      return matches
    });
    return users;
  }
})
