ng-repeat ignores values starting with a $

I guess the reason is, that the $$hash keys, angular is adding to some objects shouldnt be printed out.

Perhaps it should be changed, so that only keys starting with '$$' get ignored, or make it configureable via an attribute, something like:

<p ng-repeat="d in data" ignore="all"> - ignores $ and $$, default behavior - </p>
<p ng-repeat="d in data" ignore="$"> - ignores $ - </p>
<p ng-repeat="d in data" ignore="$$"> - ignores only $$ - </p>
<p ng-repeat="d in data" ignore="none" [or: ignore="false"]> - ignores nothing - </p>

Any suggestions?

Hi Florian
$ is used by AngularJS to indicate a hidden internal member that is not
part of the problem domain. Can you give a concrete use case where you
have a problem domain field that uses $ in keys?
You can actually get around this now with a little mapping function:

and not have to create a copy of the whole array if you wanted.

Hi Pete,

thanks four your comment and your help.
My case was, that a json response (fetched with $http) sometimes had keys starting with $ in it - not that much of a big deal in my case (since it is only a very specific section of the response where this could happen at all - your snippet will do great here, thanks!).
But I could imagine, there are other scenarios where this could happen more frequently (e.g. mongodb, since it's also using $ internally, or propably other apis i don't know of, could greatly rely on $) - what to do with these cases, I guess constantly "transforming" the data back and forth before sending it via $http isn't the best way?

In the case of MongoDB, I believe the only $ prefixed field is $oid, which is actually contained in _id so you don't iterate directly over it and in fact "A user document element name cannot begin with "$".
So closing this until a more pressing requirement is put forward.
