Is it possible to pass data into the template controller?

I want to load dynamic data according to an element Id. For that I have to pass the element Id to the template controller, but I can't find a way to do so. Any Ideas?

Hi! Yes, it is possible, since the scope of your controller is a not-isolated child-scope of the linking function`s scope (see newScope = scope.$new(false, scope) in function onTooltipTemplateControllerChange(newValue) .

Here is what I did:

1. I added new option: tooltip-id="myTooltipID" to html element I want to know ID of
2. I modified the function getAttributesToAdd(element) by adding: if (element.attr('tooltip-id') !== undefined){ attributesToAdd['tooltip-id'] = element.attr('tooltip-id'); element.removeAttr('tooltip-id'); } now myTooltipID will be stored in $attrs.
3. Since controller's scope does not inherit $attrs, the variable containing myTooltipID has to be exposed to $scope. Therefore I added following line to linkingFunction(...) : $scope.tooltipID = $attrs.tooltipId;
4. You should be able now to access the ID in your controller by checking: $scope.$parent.tooltipID;
