Fairly simple but I can't figure out the term I need to google. How do I reference whichever element is calling the controllers blurr function?
html
<body ng-app="test">
<div ng-controller="Cntrlr as cntrlr">
<input type="text" ng-model="cntrlr.inpt" ng-blur="cntrlr.blurr()" />
<input type="text" ng-model="cntrlr.second" ng-blur="cntrlr.blurr()" />
</div>
</body>
js
var app = angular.module("test", []);
app.controller("Cntrlr", ["$scope", function($scope){
this.blurr = function(){
alert("which input am I?");
alert("this is so meta.");
// ?
};
}]);
[edit]
I realized I meant to be more abstract than I was so I created a new question because this one has been solved

You could pass the $event to the function, and figure out the target of the event from that:
<input type="text" ng-model="cntrlr.inpt" ng-blur="cntrlr.blurr($event)" />
<input type="text" ng-model="cntrlr.second" ng-blur="cntrlr.blurr($event)" />
And
$scope.blurr = function(event){
var $this = $(event.target);
console.log($this);
};
