![]() ![]() Each div has the same class and we query for a HTMLCollection using ‘ getElementsB圜lassName‘. ![]() Let’s start with a simple scenario where we have 5 divs. Today I’m going to show you how to make these objects a little bit more useful, by converting them into JavaScript arrays. They include objects with a length property, such as HTMLCollection, NodeList, argument list and even strings. but it is far from so.Facebook Share Twitter Share LinkedIn ShareĮver had an array-like object that you want to iterate over? These annoying collections, which look like arrays, don’t have access to useful array methods like the ‘ forEach‘ loop. This may sound obvious to someone who has never implemented their own ArrayObject class. Since that is impossible to do directly, you must use ArrayObject's offset methods to manipulate it indirectly.Īs a side benefit, this means you inherit all the iteration and other functions in complete working order. If you plan to derive your own class from ArrayObject, and wish to maintain complete ArrayObject functionality (such as being able to cast to an array), it is necessary to use ArrayObject's own private property "storage". ArrayObject::unserialize - Unserialize an ArrayObject.ArrayObject::uksort - Sort the entries by keys using a user-defined comparison function.ArrayObject::uasort - Sort the entries with a user-defined comparison function and maintain key association.ArrayObject::setIteratorClass - Sets the iterator classname for the ArrayObject.ArrayObject::setFlags - Sets the behavior flags.ArrayObject::serialize - Serialize an ArrayObject.ArrayObject::offsetUnset - Unsets the value at the specified index. ![]()
