AngularJS change property value based on another array - json

Question

I have a json data structured as:
$scope.items = [{"Color" : "Red", "Size": "Small" }, { "Color" : "Orange" "Size": "Small"}, {"Color" : "Green" "Size": "Extra-Large"}];
then I have a properties json data:
$scope.properties = [{"PropertyName" : "Color", "FilteredAs" : "AllColors"}, {"PropertyName" : "Size", "FilteredAs" : "AllSizes"}]
I am doing a server-side filtering that's why there's a FilteredAs property in my properties json data. What I want to happen is:
If (items.key = properties.PropertyName)
example: "Color" (which is the first property in the items array) == "PropertyName" : "Color"
then that corresponding object's FilteredAs property in the properties array is "FilteredAs" : "AllColors", AllColors will be changed to "Red".
Any ideas on how to achieve this? Thanks!
EDIT: This is what I have for now:
angular.forEach($scope.items, function (value, key) {
for (var i = 0; i<= $scope.properties.length; i++) {
if ($scope.properties[i].PropertyName == $scope.items[value]) {
$scope.properties[i].SearchText = $scope.items[key];
}
}

If I understand it correctly as $scope.properties is an array you would need to foreach through the objects and identify the property that is for Color. Below should do what your looking for.
$scope.properties.forEach(function (property) {
if (property.PropertyName === "Color") {
property.FilteredAs = "Red" // Or whatever value or variable you have got back from webservice
}
});
Hope I have understood correctly and that this helps.
EDIT:
Because $scope.items is an array angular.forEach doesn't work that same way as it does for an object. You would need to change the code to be something like below.
angular.forEach($scope.items, function (item) {
for (var i = 0; i<= $scope.properties.length; i++) {
if ($scope.properties[i].PropertyName == "Color") {
$scope.properties[i].SearchText = item.Color;
}
}
With this though the value of $scope.properties[i].SearchText will always be the last Color in the $scope.items array. You might need to add some checked to ensure the right color is selected from the array with what your WebService says.
