I have a list of items with "ng-repeat". Each item contains a div with a link title and link category. When clicking on a category, I want to filter the list of items, so that it only shows the items belonging to that category. how can I achieve that?
So far I have a list of items:
<div class="link_line" ng-repeat="link in links | filter: ? ">
<div class="title"><a href="{{link.url}}" target="_blank">{{link.title}}</a></div>
<div class="category_label" ng-click="filterCategory(link)>{{ link.category }}</div>
</div>
And in the controller I have a function "filterCategory" which shows an alert with the link category. And I have the "filter: ?" where I guess the value of the filter has to come. Ths is the controller function:
$scope.filterCategory = (link) ->
alert(link.category)
Any idea how to proceed? Thanks!
You can create an object on your controller's scope intended for filtering and pass it to the filter expression in ng-repeat
var app = angular.module('app', []);
app.controller('main', function($scope) {
$scope.filters = { };
$scope.links = [
{name: 'Apple', category: 'Fruit'},
{name: 'Pear', category: 'Fruit'},
{name: 'Almond', category: 'Nut'},
{name: 'Mango', category: 'Fruit'},
{name: 'Cashew', category: 'Nut'}
];
});
So now we have a filters object attached to the scope. If it gets a key of category, the filter expression will automatically filter the objects according to whether or not they have a key of category and it matches.
For more details, look at the "Parameters" section of the filter docs.
So your HTML could look like:
<div class="link_line" ng-repeat="link in links | filter:filters">
<div class="title"><a href="{{link.url}}" target="_blank">{{link.title}}</a></div>
<div class="category_label" ng-click="filters.category = link.category">{{ link.category }}</div>
</div>
