angular 绑定动态变量

$scope.objtype=[];


for (var i = 0; i < $scope.objtype.length; i++) {
    $scope.objtype[i] = false;
}
var f="ddd"
$scope.objtype[e+""]=true;

<div class="roomunititem" ng-bind="item.UnitName" ng-class="{"backgrounde3e3e3":!objtype[{{$index}}],"backgroundf4bb48":objtype[{{$index}}]}" ng-click="showUnit($index)">1单元</div></span>

多变量

        $scope.noblock = [];
        //单击栋数选择房间
        $scope.checkBlock = function (pindex, index, BuildingId) {
            $scope.noblock = {};
            $scope.noblock[pindex+""+index] = true;
        }

<span class="hidebox " ng-class="{"blockclick":noblock[{{$parent.$index}}{{$index}}],"blocknoclick":!noblock[{{$parent.$index}}{{$index}}]}"  ng-click="checkBlock($parent.$index,$index,it.BuildingId)"  style="position:relative;">
                    <label  ng-bind="it.BuildingName"></label>
                </span>
