How come the $index value is not being retrieved in my directive?

I am working with a directive that looks like this:

.directive('grapharea', function () {
return {
    restrict:'C',
    compile: function (element, attr) {
        debugger;
        //the issue is that attr.passed is being set to graph_${{row.id}} instead of graph_1 or graph_2 ...
        return function postLink(scope, element, attrs) {

        };
    }
};
})

Below is the ng-repeat code I'm using:

<div ng-repeat="row in rows">
    <div id="graph_{{$index}}" data-passed="{{row.passed}}" data-failed="{{row.failed}}" class="grapharea"></div>
</div>

Question: Why is the $index value not appearing in my directive?

Answer №1

The compile function runs once for every directive. It seems like the link function would be more suitable in this case, as it gets called each time the directive is used, rather than just once during compilation.
