clone

问题 So I have a button on the left and a form on the right. If you click the button on the left you can create up to 6 forms. If i create these forms in html manually everything displays correctly. However since I am cloning them, they seem to be acting weird. For example on about the 4th clone the button gets pushed down instead of staying at the top left. Also each time the section is cloned i update the number of which form that is. But how do i make them stay inside the grid and how do i make

问题 I have a li element parented to a div with id holder . I need to clone the li multiple times, have all the clones parented to the holder div and change their data-ids .

问题 I'm working on coding some data structures on my own time. I've noticed that the clone method is not copying the list as I expect. I'll post my results underneath the code as the main method is near the bottom of the class. Here is the class I have written so far: public class DoublyLinkedList<E> implements Cloneable { //------------nested Node class------------ private static class Node<E> { private E element; // reference to stored element private Node<E> prev; // reference to previous

Closed 4 years ago . new String[] { "foo", "bar" }.clone(); With my favorite IDE (i.e. Eclipse), I wanted to see the source code of the above clone() method by Ctrl-clicking on it (as usual), but it brought me to the Object 's native one, which provides only the signature and not the body of the method.

问题 Can I use NFC tag as authentication tool, for example when the tag is tapped, it opens a url, connects to a remote database and checks if that is the original Tag and returns true or false. The information and the url will be public so anyone can tap the tag, but if someone copy its content to another tag, then it connects to the database it will return false. So actually that would be a public tag but with an unique identificator that can't be copied. Hope it makes sense, im new to the NFC

问题 I need a simple function to map a list of primitive properties from one object to another. I wrote one myself, but I guess there's already a proven method to achieve this. var mapProperties = function (props, from) { var to = {}; for (var i = 0; i < props.length; i++) { to[props[i]] = from[props[i]]; } return to; } Then use the function like: var fromObj = { foo: "foo", bar: 1 } var toObj = mapProperties(['foo', 'bar'], fromObj); Any better ideas? 回答1: If you are not looking to DeepClone,

问题 I have a javascript function that gets a DIV by an ID and makes a clone.
