Answer 1

You would basically turn that "where..." for into a filter pipe: http://docs.angularjs.org/api/ng/filter/filter

Eg, try:

ng-repeat="disc in prolist | filter:{Pt_id: pt.id}" ...

You can filter repeaters in AngularJS. Try using filter, the following link displays how to use filters with ng-repeat.

如果您的数据集很大，则可以使用javascript进行过滤，然后将对象推送到$ scope.prolist以在视图中呈现该视图，因为过滤器对性能的影响很大，但对于较小的数据集来说就可以了。
