Search by multiple values in object

filter() function works only for array. So you need to make itemPrices an array. There are two ways to transform the object to an array:

The first one is, if you can change the object, add a length property to it and then use Array.prototype.slice.call(itemPrices) method to make it an array, check out the updated jsfiddle.

The second one is easier to understand:

var itemPrices = {
		'1':  { 'catid': '1', 'typeid': '1', 'price': '1000' },
		'2':  { 'catid': '1', 'typeid': '2', 'price': '1000' },
		'3':  { 'catid': '1', 'typeid': '3', 'price': '1100' },
		'4':  { 'catid': '2', 'typeid': '1', 'price': '1000' },
		'5':  { 'catid': '2', 'typeid': '2', 'price': '1000' },
		'6':  { 'catid': '2', 'typeid': '3', 'price': '1100' },
		'7':  { 'catid': '3', 'typeid': '1', 'price': '1200' },
		'8':  { 'catid': '3', 'typeid': '2', 'price': '1200' },
		'9':  { 'catid': '3', 'typeid': '3', 'price': '1300' },
		'10':  { 'catid': '4', 'typeid': '1', 'price': '1200' },
		'11':  { 'catid': '4', 'typeid': '2', 'price': '1200' },
		'12':  { 'catid': '4', 'typeid': '3', 'price': '1300' },
	};

var arr = [];

for (var item in itemPrices) {
  if (itemPrices.hasOwnProperty(item)) {
        arr.push(itemPrices[item])
  }
}

var price = arr.filter(function(item) { return item.typeid == 1 && item.catid == 2; });
	
console.log(price);
