Filter angular material combo box












0















I am dynamically adding multiple combo boxes. If a value in the previously existing combo box is selected I am removing it from the array. The end result must me unique values selected in the combo boxes. I decided to achieve that by filtering out previously existed values. Is this the right approach?
So far my filter doesn't work.



<div ng-repeat="choice in $ctrl.inputFilterRows">
<md-select ng-model="choice.name">
<md-option ng-repeat="filter in choice.filters" value="{{filter.value}}" | filter:filterTest()>
{{filter.value}}
</md-option>
</md-select>
</div>

<md-button ng-click="$ctrl.addFilter()">ADD FILTER</md-button>


Controller:



var filtersArray = [
{ value: 'Filter1' },
{ value: 'Filter2' },
{ value: 'Filter3' }
];

$scope.filterTest = function () {
return function (item) {
if (item.value === 'Filter3') {
return true;
}
return false;
};
};



self.addFilter = function () {
var index = self.inputFilterRows.length;
var newItemNo = index + 1;
self.inputFilterRows.push({ 'name': 'inputFilter' + newItemNo, 'input': '' });

self.inputFilterRows[index].filters = filtersArray;
};
