Say I have an object like this
$scope.products = {
blueDuck: {type:'duck', price: 5},
redDuck: {type:'duck', price: 8},
greenWolverine: {type:'wolverine', price:15}
}
I want to loop over the elements by type:
angular.forEach($scope.products, function(key, value) {
console.log(value.type);
});
That would output:
duck
duck
wolverine
When I want to get a variable that's like:
duck
wolverine
var items = []; //The temporary array to keep the values
angular.forEach($scope.products, function(key,value) {
if(items.indexOf(value) === -1) { //Check if the values is not already in the temp array
items.push(key); //Push it to array
}
});
console.log(items); //Show the content of the array
you can store the variables coming from the loop inside an array, and check if the array contains your data from the loop. this is something i came up with
var items = [];
angular.forEach($scope.products, function(key,value) {
if(items.indexOf(value) === -1) {
items.push(key);
console.log(value.type);
}
});
