I\'m running a simple ng-repeat
over a JSON file and want to get category names. There are about 100 objects, each belonging to a category - but there are only
Add this filter:
app.filter('unique', function () {
return function ( collection, keyname) {
var output = [],
keys = []
found = [];
if (!keyname) {
angular.forEach(collection, function (row) {
var is_found = false;
angular.forEach(found, function (foundRow) {
if (foundRow == row) {
is_found = true;
}
});
if (is_found) { return; }
found.push(row);
output.push(row);
});
}
else {
angular.forEach(collection, function (row) {
var item = row[keyname];
if (item === null || item === undefined) return;
if (keys.indexOf(item) === -1) {
keys.push(item);
output.push(row);
}
});
}
return output;
};
});
