filterFilter is Angular's dependency injection for using filters in a controller (filter name + Filter as a suffix). In this case, the filter's name is just "filter", hence "filterFilter". You can do this instead of injecting $filter. More information can be found on this SO question if you're looking for additional explanation: http://stackoverflow.com/questions/14302267/how-to-use-a-filter-in-a-controller/14303362#14303362
Thanks a lot! Very useful :)
Just what I was looking for, thank you!!
This is fine for a static data set (like $scope.items) in this case. Mostly that would not be the case, what if i'm getting the data dynamically using a https service. The data(dynamically fetched $scope.items) then won't be available outside that function scope. Can you please tell me how to solve such problem.
I am sharing curiosity with @NikhilNanjappa
Hi, I get input is not defined in startForm filter, any idea?
Hello,
I know you answered about "filterFilter" above on Feb 2, but I still don't understand it.
I downloaded your code and changed $filter('startFrom')($scope.items, newVal) instead of "filterFilter".
Then search works but pagination doesn't updated. I thought "filterFilter" calls app.filter('startFrom', function (){}. Would you explain what function "filterFilter" is calling?
Thank you,
Awesome way to do it! Thanks a lot! +star
For live testing: http://plnkr.co/edit/Q26WPjLqcOtS8p0mGF6b?p=preview
don't need startFrom, just use limitTo: perPage : (currentPage-1)*perPage
why if type on input search "HelloWorldNotFonud"
when clear input, not show records.

Instead of building object $scope.items in controller I am fetching as json using ajax from server. So how can we implement this ?
@abhilive, it's essentially the same way except you'd have the items loaded from the server. This is the way I did it. Note that I use ControllerAs syntax as opposed to $scope. I do that with the angular.bind call in $watch (of course, some of my names differ but you should be able to figure it out.
$scope.$watch(angular.bind(this, function () {
return this.search;
}), function (newVal, oldVal) {
self.pagedClients = filterFilter(self.clients, newVal);
self.totalClients = self.pagedClients.length;
self.numPages = Math.ceil(self.totalClients / self.perPage);
self.currentPage = 1;
}, true);
You'll also need to set the initial values for these when the data is first loaded and force the $watch to run.
... // ajax
.then(
function (data) {
self.clients = data;
self.totalClients = self.clients.length;
self.numPages = Math.ceil(self.totalClients / self.perPage);
self.currentPage = 1;
self.search = '';
},
...// more ajax
Thanks for this, helped me out a lot.
OrderBy field?
Good example. thanks
Thank you so much for this, This helps me with my current roadblock!
Currently having issues getting this to work inside Ajax call... I'd appreciate any help.. Spent a few hours on this :(
Main issue:
- Pagination works fine but the filter doesnt. When I tried to filter an item(about 3000 items), it was only able to filter the page its currently on. For instance, if I'm on page 1, and searched for an item on page 8, it will return nothing, but if the item I'm searching for is on page 1, it will return the result.
I know I'm missing something...
Fixed the above! thanks all!
Thanks for the post, here my question is when data increases the pagination numbers also increase. Is there way to show only few numbers with dots.....
what the hell ? pagination tag...
@manjunath10073 i think to limit the buttons, we need to change the max-size value
<pagination page="currentPage" max-size="5" total-items="totalItems" items-per-page="entryLimit"></pagination>
hi,
Same condition. but not working in my project. only change <script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.10.0.js" type="text/javascript"></script> to <script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-1.3.3.js" type="text/javascript"></script>
plunker example code here,

Hello, Thanks for the post, it helped a lot in implementing a pager. I am a little confused on what the filterFilter is...?
I made a few adjustments to my needs, instead of the watcher I used the filtered object inline
pagination total-items="filtered.length"
ng-repeat="item in filtered = (results | SubCategory:subcat) | startFrom:(CurrentPage-1)*ItemsPerPage | limitTo:ItemsPerPage "
This provides the items as filtered after the results has been run through a custom filter to allow for multiple subcategories for a shopping cart refining filter and then runs that array against the startFrom and limitTO filters.
