I am using a nested ng-repeat and a filter on a object. The first ng-repeat is filters to the headerId in a gapHeader object. The second ng-repeat filters gapSection, sectionId to the corresponding headerID.
I have an edit page which is within a separate modal window. The purpose is to edit content corresponding to the headerID & sectionID of the sub-object) This also has a separate control. Data is shared through a service.
My problem I have a button for each gapSection sub-object, which opens the edit page modal, when I pass the $index value for the current section within each section to the service, I get the $index only corresponding to the second ng-repeat? For example, if I click the button within the 2 ng-repeat on gapSection (headerId:2, sectionId:2), I get an $index of 1. I require an $index of 2 which corresponds the sub-object position within gapSection.
Is it possible to pass the true $index which corresponds to the $index defined in the original un-filtered object of gapSection? Appreciate any comments on this and thank you!
Object:
var data ={
gapHeader:[{headerId:1,name:"General Requiremets",isApplicable:true},
{headerId:2,name:"Insurance",isApplicable:false}],
gapSection:[{headerId:1,sectionId:1,requirement:"A facility is required to have company structure",finding:null,cmeasures:null,cprocedures:null,personResp:null,isAction:null},
{headerId:2,sectionId:1,requirement:"Organisation must have public liablity",finding:null,cmeasures:null,cprocedures:null,personResp:null,isAction:null},
{headerId:2,sectionId:2,requirement:"Facility must hold workers compensation insurance",finding:null,cmeasures:null,cprocedures:null,personResp:null,isAction:null}]
};

Note: The $index variable is used to get the Index of the Row created by ng-repeat directive. Each row of the HTML Table consists of a Button which has been assigned ng-click directive. The $index variable is passed as parameter to the GetRowIndex function.
The ng-repeat values can be filtered according to the ng-model in AngularJS by using the value of the input field as an expression in a filter. We can set the ng-model directive on an input field to filter ng-repeat values.
But ng-repeat is not the right thing to use when you have large datasets as it involves heavy DOM manipulations. And you should consider using ng-repeat with pagination. You can consider using transclusion inside a custom directive, to achieve the behavior you are looking for without using ng-repeat.
$first and $last It's common when using ng-repeat to add specific behavior to the first or last element of the loop, e.g. special styling around the edges. Instead, ng-repeat already supplies you with two ready boolean properties. $first is true for the first element, and $last is true for the last element.
If you need the true index you do not even need to pass the $index property, just pass the object and get the index from the original list.
i.e
$scope.gapSectionFn = function(obj){
var idx = data.gapSection.indexOf(obj);
}
Also it is not clear your issue could really be a nested ng-repeat issue, because according to you gapSection is the inner ng-repeat and you are invoking the call from inner ng-repeat and in need of gapSection's index. It should just be available, but the presence of a DOM filter will just reorg the items and its index which you can also get by doing an ng-init, i.e on the view ng-init="actIndex=$index" and use actIndex.
If you are trying to access parent ng-repeat's index then, ng-init is more appropriate than $parent.$index. Since ng-init is specially designed for that., on the parent ng-repeat you would write ng-init=""parentIndex=$index" and use parentIndex.
