Beware of properties inherited from the object’s prototype (which could happen if you’re including any libraries on your page, such as older versions of Prototype). You can check for this by using the object’s hasOwnProperty() method. This is generally a good idea when using for…in loops: var user = {}; function setUsers(data) { for (var … Read more
If you only need the dictionary keys 1, 2, and 3 use: your_dict.keys(). If you only need the dictionary values -0.3246, -0.9185, and -3985 use: your_dict.values(). If you want both keys and values use: your_dict.items() which returns a list of tuples [(key1, value1), (key2, value2), …].
There are various ways to solve this, here’s three of them: Use a callback for the valueField Use a callback and stitch the value together by using values from the results. $query = $this->LocationsUser->Users ->find(‘list’, [ ‘valueField’ => function ($row) { return $row[‘first_name’] . ‘ ‘ . $row[‘last_name’]; } ]) ->where([‘id’ => $id]); See also … Read more
Right click on the folder you want to add it to and choose “New file…” From the Dialog – create a new Resource file of type Property List: Give it whatever name you want, the plist extension will be added for you. In this case I’ve created Root.plist This will bring up a blank file … Read more
int and const int are two distinct types. std::map<int, float> and std::map<const int, float> are, similarly, different types. The difference between std::map<const int, float> and std::map<int, float> is, to a degree, analogous to the difference between, say, std::map<int, float> and std::map<std::string, float>; you get a fresh map type for each. In the non-const case, the … Read more
Two terms for the same thing: “Map” is used by Java, C++ “Dictionary” is used by .Net, Python “Associative array” is used by PHP “Map” is the correct mathematical term, but it is avoided because it has a separate meaning in functional programming. Some languages use still other terms (“Object” in Javascript, “Hash” in Ruby, … Read more
for (NSString* key in xyz) { id value = xyz[key]; // do stuff } This works for every class that conforms to the NSFastEnumeration protocol (available on 10.5+ and iOS), though NSDictionary is one of the few collections which lets you enumerate keys instead of values. I suggest you read about fast enumeration in the … Read more
You’ll want a Map<String, String>. Classes that implement the Map interface include (but are not limited to): HashMap LinkedHashMap Hashtable Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default. For example (using a HashMap): Map<String, String> map = new HashMap<String, String>(); … Read more
var dict = []; // create an empty array dict.push({ key: “keyName”, value: “the value” }); // repeat this last part as needed to add more key/value pairs Basically, you’re creating an object literal with 2 properties (called key and value) and inserting it (using push()) into the array. Edit: So almost 5 years later, … Read more
You can do it like this: #Just an example how the dictionary may look like myDict = {‘age’: [’12’], ‘address’: [’34 Main Street, 212 First Avenue’], ‘firstName’: [‘Alan’, ‘Mary-Ann’], ‘lastName’: [‘Stone’, ‘Lee’]} def search(values, searchFor): for k in values: for v in values[k]: if searchFor in v: return k return None #Checking if string ‘Mary’ … Read more
