AngularJS 上是否有任何内置功能可以避免 ng-repeater 接收重复的条目?
现在我正在使用以下代码来防止它:
$scope.tags = ['black','white','red','yellow','blue'];
$scope.selectedTags = [];
// textarea value
var words = $scope.message.split(' ');
for(var j = 0; j < words.length; j++) {
for (var k = 0; k < $scope.selectedTags.length; k++) {
if ($scope.selectedTags[k].Name == words[j]) {
contains = true;
}
}
if (!contains)
{
$scope.selectedTags.push($scope.tags[i]);
contains = false;
}
}
