Angularjs - Pagination appear after search filter

Question

I am newbie on AngularJS.

Search result can be displayed in one page but why the next and previous button is showing ?

 <input type="text" id="txtNotessearch" ng-model="search_notes" class="form-control input-sm" placeholder="SEARCH">
 ...
    <ul>
        <li ng-repeat="item in data | filter:search_notes | startFrom:currentPage*pageSize | limitTo:pageSize">
                    {{item}}
        </li>
    </ul>

Correct me, if I am wrong.

after my search only two result is appeared and then why pagination is coming. — Madhes, Aug 27 '14 at 10:35
I think s/he means that the search result can be displayed in one page but why the `next` and `previous` button is showing. — khemry, Aug 27 '14 at 10:37
u don't need startFrom, `limitTo` [already have third option](https://docs.angularjs.org/api/ng/filter/limitTo) `begin`, so, u can change ur code to `limitTo: pageSize: currentPage*pageSize` — Sergio Ivanuzzo, Jan 26 '16 at 21:27

Because NumberOfPages is not filtered. Instead of using $scope.data.length, you should use the length after the filter.

function MyCtrl($scope, $filter) { //Do not forget to inject $filter
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];

    $scope.numberOfPages=function(){
        var myFilteredData = $filter('filter')($scope.data,$scope.search_notes); //Filter the data
        return Math.ceil(myFilteredData.length/$scope.pageSize);                
    }
    for (var i=0; i<45; i++) {
        $scope.data.push("Item "+i);
    }
}

In addition, I would modify the ng-disable next button to

button "ng-disabled="(currentPage + 1) == numberOfPages()"

And I would add to search_notes onchange currentPage=1.

I have some query,If I'm in 3rd page and i will search "15".Now next and previous button is problem – Madhes Aug 27 '14 at 12:27
Yes Madhes, that's because I suggested to change to currentPage = 1 when you change your Search input :) – Mario Levrero Aug 27 '14 at 12:32
