How to filter (key, value) with ng-repeat in AngularJs?

I am trying to do something like :

<div ng-controller="TestCtrl">
<div ng-repeat="(k,v) in items | filter:hasSecurityId">
{{k}} {{v.pos}}
</div>
</div>


AngularJs Part:

function TestCtrl($scope)
{
$scope.items = {
'A2F0C7':{'secId':'12345', 'pos':'a20'},
'C8B3D1':{'pos':'b10'}
};

$scope.hasSecurityId = function(k,v)
{
return v.hasOwnProperty('secId');
}
}
But somehow, it is showing me all items. How can I filter on (key,value) ?

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>

Or simply use

ng-show="v.hasOwnProperty('secId')"

You can simply use [angular.filter][1] module, and then you can filter even by nested properties.<br/>
see: [jsbin][2]<br/>
**2 Examples:**<br/>

**JS:**

angular.module('app', ['angular.filter'])
.controller('MainCtrl', function($scope) {
//your example data
$scope.items = {
'A2F0C7':{ secId:'12345', pos:'a20' },
'C8B3D1':{ pos:'b10' }
};
//more advantage example
$scope.nestedItems = {
'A2F0C7':{
details: { secId:'12345', pos:'a20' }
},
'C8B3D1':{
details: { pos:'a20' }
},
'F5B3R1': { secId:'12345', pos:'a20' }
};
});

**HTML:**

<b>Example1:</b>
<p ng-repeat="item in items | toArray: true | pick: 'secId'">
{{ item.$key }}, {{ item }}
</p>

<b>Example2:</b>
<p ng-repeat="item in nestedItems | toArray: true | pick: 'secId || details.secId' ">
{{ item.$key }}, {{ item }}
</p>

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;
}

It is kind of late, but I looked for e similar filter and ended using something like this:

<div ng-controller="TestCtrl">
<div ng-repeat="(k,v) in items | filter:{secId: '!!'}">
{{k}} {{v.pos}}
</div>
</div>

I made a bit more of a generic filter that I've used in multiple projects already:

- object = the object that needs to be filtered
- field = the field within that object that we'll filter on
- filter = the value of the filter that needs to match the field

**HTML:**

<input ng-model="customerNameFilter" />
<div ng-repeat="(key, value) in filter(customers, 'customerName', customerNameFilter" >
<p>Number: {{value.customerNo}}</p>
<p>Name: {{value.customerName}}</p>
</div>

**JS:**

$scope.filter = function(object, field, filter) {
if (!object) return {};
if (!filter) return object;

var filteredObject = {};
Object.keys(object).forEach(function(key) {
if (object[key][field] === filter) {
filteredObject[key] = object[key];
}
});

return filteredObject;
};

Although this question is rather old, I'd like to share my solution for angular 1 developers. The point is to just reuse the original angular filter, but transparently passing any objects as an array.

app.filter('objectFilter', function ($filter) {
return function (items, searchToken) {
// use the original input
var subject = items;

if (typeof(items) == 'object' && !Array.isArray(items)) {
// or use a wrapper array, if we have an object
subject = [];

for (var i in items) {
subject.push(items[i]);
}
}

// finally, apply the original angular filter
return $filter('filter')(subject, searchToken);
}
});

use it like this:

<div>
<input ng-model="search" />
</div>
<div ng-repeat="item in test | objectFilter : search">
{{item | json}}
</div>
