I want to use the filter
in angular and want to filter for multiple values, if it has either one of the values then it should be displayed.
I have for example this structure:
An object movie
which has the property genres
and I want to filter for Action
and Comedy
.
I know I can do filter:({genres: 'Action'} || {genres: 'Comedy'})
, but what to do if I want to filter it dynamically. E.g. filter: variableX
How do I set variableX
in the $scope
, when I have an array of the genres I have to filter?
I could construct it as a string and then do an eval()
but I don't want to use eval()...
I would just create a custom filter. They are not that hard.
angular.module('myFilters', []).
filter('bygenre', function() {
return function(movies,genres) {
var out = [];
// Filter logic here, adding matches to the out var.
return out;
}
});
<h1>Movies</h1>
<div ng-init="movies = [
{title:'Man on the Moon', genre:'action'},
{title:'Meet the Robinsons', genre:'family'},
{title:'Sphere', genre:'action'}
];" />
<input type="checkbox" ng-model="genrefilters.action" />Action
<br />
<input type="checkbox" ng-model="genrefilters.family" />Family
<br />{{genrefilters.action}}::{{genrefilters.family}}
<ul>
<li ng-repeat="movie in movies | bygenre:genrefilters">{{movie.title}}: {{movie.genre}}</li>
</ul>
Edit here is the link: Creating Angular Filters
UPDATE: Here is a fiddle that has an exact demo of my suggestion.
