Easier setup for deep object based filtering on an array in angularjs. Use: ng-repeat="item in someArray | objectFilter:filterReqObject"

Dynamic Angular Array Filter

// I wanted to be able to simply change an object with key/search values, so that any array item keys that match also check for those search values
// The returned data, is only data that meets all requirements inside of the filterObject
// 
// Example filterObject:{
//      names: "Trevor",
//      countries: "USA"
// }
// Example Array: [{
//      title: "People in USA"
//      names: ["Trevor", "Steve"]
//      countries: ["USA"]
// },{
//      title: "People in the world"
//      names: ["John", "Steve"]
//      countries: ["EU","USA"]
// }]

App.filter('objectFilter', [function($filter) {
    return function(inputArray, filterObject){
        if(!angular.isDefined(filterObject) || filterObject === ''){
            return inputArray;
        }

        // assume the item has all filters until proven false
        function hasAllFilters ( item ){
            for(var meta in filterObject){
                if(item[meta].indexOf(filterObject[meta]) === -1){
                    return false;
                }
            }
            return true;
        }

        // setup only data that meets all requirements
        var data = [];
        angular.forEach(inputArray, function(item){
            if(hasAllFilters(item)){
                data.push(item);
            }
        });

        return data;
    };
}]);
