I have the following code:
<select name="condition"
ng-options="operation.id as operation.description for operation in Operators | myfilter:criterion_id" >
</select>
and
module.filter('myfilter', function () {
return function (x) {
return ?????
};
});
I want to populate my select list with those options whose operation.id equals criterion_id. How may I achieve that?
You don't need to make your own filter, Angular's default filter will work:
<select name="condition"
ng-options="operation.id as operation.description for operation in Operators | filter:{id:criterion_id}" >
</select>
You should filter your array based on a condition and return the filtered array.
module.filter('myfilter', function () {
return function (arrayOptions, criterion_id) {
var result = [];
result = arrayOptions.filter(function(operation){
return (operation.id == criterion_id);
})
return result;
};
});
But you should do this in case of a complex filtering process with data manipulation, otherwise you should use filter filter from Angular.
Operators | filter: {id: criterion_id}
I've just written some code here.. please check it: http://jsfiddle.net/k86sy0ku/1/
<select
ng-options="p as p.first for p in people | filter:{id:FilterId}"
ng-model="selectedPerson"></select>
