Angularjs First In Array After Filter
Solution 1:
This can be done by injecting the filter's dependency into a controller and calling it in code like
var filteredArray = filterDependency(arrayToFilter,args);
which returns a new, filtered array. Since you are using the "filter" filter (it's a filter whose name is filter), the dependency injection should be filterFilter. Your controller should look something like this:
var app = angular.module('myapp',[]);
app.controller('ctrlParent',function($scope,filterFilter){
var filteredArray = [];
$scope.list = ["abc","def","ghi","abcdefghi"];
$scope.$watch('search',function(newValue){
filteredArray = filterFilter($scope.list, newValue);
// do something with the first result
console.log(filteredArray[0]); // first result
});
});
What we're doing is setting a watch on the input model (search) so we can get the new value and re-filter the array any time the input is changed.
Also:
If you need to access the ng-repeat index from within the view, you can use the special property $index inside of the ng-repeat like:
<div ng-repeat="item in list | filter:search">
{{$index}}
</div>
You can also use $first, $middle, and $lastas shown in this Angular doc.

Solution 2:
Not with bracket access. If you have an ng-repeat with a filter:
ng-repeat="thing in things | filter:search"The filtered list here is kind of anonymous - it doesn't have a name that you can access.
That said, if you take a look at the docs for ngRepeat, you'll see that inside each repeater's scope, you have access to $index, $first, $middle, and $last.
So something like
<body ng-app="App" ng-controller="Main">
<pre ng-repeat="n in nums | filter:isOdd">
n={{n}}:index={{$index}}:first={{$first}}:middle{{$middle}}:last={{$last}}
</pre>
</body>
Would yield:
n=1:index=0:first=true:middlefalse:last=false
n=3:index=1:first=false:middletrue:last=false
n=5:index=2:first=false:middlefalse:last=trueSolution 3:
Are you using "ng-repeat"? If so take a look at the properties $first, $index, $middle, and $last. This will allow you to get info on the specific item from the repeat.
