Is there a specific AngularJS method to retrieve a value from an object using its key?
var myobj= {
"set1": {
"key": "B11",
"color": "yellow"
},
"setA": {
"key": "F34",
"color": "green"
}
}
For example, if I want to access the value "green" by providing the key "F34" in the object myobj, is there a built-in AngularJS way to achieve this or should I refer to resources like this SO question?
If you're looking to streamline this process across various controllers and services, consider creating a personalized filter to handle the task efficiently.
angular.module('myApp').filter('retrieveColor', retrieveColor);
function retrieveColor() {
return filter;
function filter(object, key) {
var color;
angular.forEach(object, function(set) {
if (set.key === key)
color = set.color;
});
return color;
}
}
This custom filter can then be implemented as follows:
$scope.color = $filter('retrieveColor')(myobj, 'F34');
