clone

问题 I want to make a deep copy method. I seeked help here the other day with this issue, but that was for a copy constructor. Now I need a regular method. I have the code created (nonworking), but I'm just not understanding it completely. public GhostList deepCopy(){ int length=this.getLength(); GhostList jadeed=new GhostList(); Ghost[] data = new Ghost[length]; for (int i=0;i<this.getLength();i++){ data[i] = new Ghost(); data[i].setX(this.ghosts[i].getX()); data[i].setY(this.ghosts[i].getY());

问题 please be gentle, I'm just learning. I'm trying to clone a div multiple times. I can get it to do it once, but not several times. I'd like to do it w/out JQuery (trying to understand basic Javascript first). Below is a sample. What am I doing wrong? var myDiv = document.getElementById("test"); var divClone = myDiv.cloneNode(true); // the true is for deep cloning document.body.appendChild(divClone); document.body.appendChild(divClone); document.body.appendChild(divClone); Here it is on

问题 I have a dynamic form that can be cloned, using the SheepIt! plugin to clone my form elements. My form has a dynamic set of dropdown boxes, where the second dropdown box display a set of values based on the selection from the first dropdown box. My problem is that the dynamic function of the dropdown boxes is not functioning on cloned dropdowns, and only works for the first dropdown on the page. Any ideas why this is happening? I created a fiddle so you can see how the SheepIt! plugin works,

问题 I'm creating a library of very common, very simple shapes. Sphere would be a member, as well as torus, and so on. Torus has two radius fields, whereas sphere has one; that modified behavior is something we can provide by changing the implementation of functions to include both radii, and of course, adding the extra radius field. Torus is common enough that inclusion of that behavior in the permanent library is beneficial. On the other hand, "WigglyTorus", a torus whose radii oscillate, would

问题 I am using jquery to clone and append some html into a div. My problem is that this html will be removed when the page is refreshed. The question is how I can save the appended HTML in the div (the html code will contain some inputs and select lists and there will be plenty of code). What should I look into? Cookies? HTML5? Anything else? 回答1: If you're only going to support modern browsers I would go for HTML5's offline storage. Another approach would be to get the AJAX route. You don't want

问题 I have a bunch of handy aliases set up in the config file for my git repository. I will occasionally clone this repository (e.g. onto my laptop), but the clone does not included any of the aliases I've set up, presumably because the clone does not copy the git config file where the aliases are stored. I would, however, like to have these aliases available when working with the clone without having to set them up again manually. Has anyone found a good solution for this? 回答1: You can put

问题 i am trying to add class (.trans) to my newly made clone in jquery. .but its not working. ... when i am applying class directly to my object then its working perfectly. What i am trying to do is.. i fetch some images from database to my page. with foreach loop i displayed those images.. then with the help of jquery clone method i create a clone of particular image when i clicked on it and the clone will displayed in a different div. now i want to add a particular class to my newly created

问题 I am deep-cloning instances of a certain class by implementing clone() in this class and in its whole hierarchy of fields that compose it. In the clone() implementations that I put in these classes, I assign each field of the new instance by calling clone() on the corresponding field of the original ( this ). Then I just call clone() on the main class. I believe this is quite a standard way of deep-cloning. Below there is a small runnable example. The clone I get is a real deep copy, where

问题 I just started from: http://jsfiddle.net/FJFFJ/1/ (by Chain dynamically created dropdowns with JQuery) It's really good but now I need to change a bit: clone the last group of selects. ie.: +- Argentina | San Juan | Rawson Chile | Santiago | Chiñihue Then, if I click at "+", it will clone Chile | Santiago | Chiñihue instead of the first one. 回答1: This is actually a harder question than I thought it would be. Apparently when you clone the set of SELECT elements it can't change to something

问题 I'm trying to wrap my head around inheritance/interfaces/implementation a bit better in .NET. I have a class that's defined as follows (sort of): Public Class Sheet Property Name As String Property Steps As List(Of [Step]) End Class The thing is, [Step] is just a virtual, base class. There are 5 different concrete implementations of [Step]. To make matters a bit more complex, there are 3 DIRECT implementations of [Step], 2 of which are virtual. Each of those 2 has 2 subclasses that would
