How to filter (key, value) with ng-repeat in AngularJs?
My solution would be create custom filter and use it:
app.filter('with', function() {
return function(items, field) {
var result = {};
angular.forEach(items, function(value, key) {
if (!value.hasOwnProperty(field)) {
result[key] = value;
}
});
return result;
};
});
And in html:
<div ng-repeat="(k,v) in items | with:'secId'">
{{k}} {{v.pos}}
</div>
Also you can use ng-repeat
with ng-if
:
<div ng-repeat="(key, value) in order" ng-if="value > 0">
Angular filters can only be applied to arrays and not objects, from angular's API -
"Selects a subset of items from array and returns it as a new array."
You have two options here:
1) move $scope.items
to an array or -
2) pre-filter the ng-repeat
items, like this:
<div ng-repeat="(k,v) in filterSecId(items)">
{{k}} {{v.pos}}
</div>
And on the Controller:
$scope.filterSecId = function(items) {
var result = {};
angular.forEach(items, function(value, key) {
if (!value.hasOwnProperty('secId')) {
result[key] = value;
}
});
return result;
}
