控制器

中的某个位置

$scope.hasDuplicate = function() {
    var sorted;

    sorted = $scope.csTagGrp[0].csTags.concat().sort(function(a, b) {
      if (a.keys > b.keys) return 1;
      if (a.keys < b.keys) return -1;
      return 0;
    });

    return sorted.some(function(nth, i){

        if(i> 0  && i < sorted.length) {
          return ((nth[i - 1].keys == nth.keys) || (sorted[i + 1].keys == nth.keys));
        }

        return false;

    });

  };

在模板中

<button type="submit" ng-disabled="hasDuplicate()"> Save </button>

在ng-repeat中重复时禁用提交按钮
