clone

问题 I am using getElementById when I need to clone the div element. Code: printHTML( document.getElementById("div_name").cloneNode(true)); Now I need to use getElementsByClassName CloneNode is not working when using getElementsByClassName . How can I put class name in here? Thank's EDIT: When I try to use this: printHTML( $('.dataTables_scroll').clone(true) ); You can see my function: function printHTML(clonedDive){ var iframe = document.createElement("iframe"); document.body.appendChild(iframe);

问题 I'm having trouble cloning a repo on git. I've been trying for to days and have tried quite a few solutions (in most the problem was slightly different but seemed to apply) but nothing has done anything to make a difference. I've tried switching off the anti-virus and firewall but that didn't help. I've also tried uninstalling and reinstalling the network adapter drivers (and restarting the computer) and that didn't work. From what I understand it's a network issue somewhere as the remote

问题 I have a Mercurial repository containing a handful of related projects. I want to branch just one of these projects to work on it elsewhere. Is cloning just part of a repository possible, and is that the right way to achieve this? 回答1: What you want is a narrow or partial clone, but this is unfortunately not yet supported. If you already have a big repository and you realize that it would make sense to split it into several smaller repositories, then you can use the convert extension to do a

问题 Clone does not call the object constructor to create a copy of the object. So what algorithm does clone use ? I am looking for implementation details of the native method clone. Any pointers will be appreciated. Note that I am aware of the shortcomings of clone. 回答1: protected native Object clone() . I don't know exactly (I need to take a look at the native code) but it makes a new instance of the object inside the JVM and copies all fields. But you should avoid using clone() - it is hard to

问题 Can someone explain me what is Object Cloning in php? When should i use clone keyword in php? 回答1: Object cloning is the act of making a copy of an object. As Cody pointed out, cloning in PHP is done by making a shallow copy of the object. This means that internal objects of the cloned object will not be cloned, unless you explicitly instruct the object to clone these internal objects too, by defining the magic method __clone() . If you don't utilize the __clone method, the internal objects

问题 So I am trieing to copy all the style that apply on one element ( class / id / tagName / attribute etc. ). So far I found out that I can copy the computed style of an element, Just one problem ... couldend apply it on outher element ;/ or diffrend way to copy all the style. (this is as far as i got :/ ) http://jsfiddle.net/8KdJd/2/ //queriks mode + minor changes to retrive the computed style function getCS(el) { if (el.currentStyle) var y = el.currentStyle; else if (window.getComputedStyle)

问题 I have an ArrayList<String> that I'd like to return a copy of. ArrayList has a clone method which has the following signature: public Object clone() After I call this method, how do I cast the returned Object back to ArrayList<String> ? 回答1: ArrayList newArrayList = (ArrayList) oldArrayList.clone(); 回答2: Why would you want to clone? Creating a new list usually makes more sense. List<String> strs; ... List<String> newStrs = new ArrayList<>(strs); Job done. 回答3: This is the code I use for that:

问题 My question is almost exactly this question: Clone textview to append it to a ViewGroup However, I was inflating a view, and then attempting to clone it at the object level for performance reasons (I don't want to parse XML every single time), so that answer doesn't help me. View.clone() is protected and it apparently doesn't have a copy constructor. Is there any way to do this? 回答1: You cannot clone views, the way to do it is to inflate your View every time. Note that the XML is compiled

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: What is the difference between a deep copy and a shallow copy? What is the difference between deep and shallow copy. What type of a copy does a copy constructor do? 回答1: Shallow copy: Some members of the copy may reference the same objects as the original: class X { private: int i; int *pi; public: X() : pi(new int) { } X(const X& copy) // <-- copy ctor : i(copy.i), pi(copy.pi) { } }; Here, the pi member of the
