copy

问题 I'm using this function to copy a URL to the clipboard: function CopyUrl($this){ var querySelector = $this.next().attr("id"); var emailLink = document.querySelector("#"+querySelector); var range = document.createRange(); range.selectNode(emailLink); window.getSelection().addRange(range); try { // Now that we've selected the anchor text, execute the copy command var successful = document.execCommand('copy', false, null); var msg = successful ? 'successful' : 'unsuccessful'; if(true){ $this

问题 I don't know how to write a macro that designates a cell within a column as a "master cell" (editable) copy that cells value to all the cells below it in that column, until it reaches a blank/clear formatted cell in column A. So I want it to look at column A to know when to stop copying the cell values in whichever column. That is, Cell "C5" will be a master cell, the macro will copy it's value from "C6:C" but looking at column A's cell values to see if it has nothing in it and there's no

问题 So lets say I want to make a deep copy of an object, but using its contsructor. So I have: public class PositionList { private Position[] data = new Position[0]; private int size = 0; public PositionList(PositionList other, boolean deepCopy) { if (deepCopy==true){ size=other.getSize(); for (int i=0;i<data.length;i++) data[i]=other.data[i]; } else { data=other.data; size = other.size; And so say I have this being called: PositionList list = new PositionList(); PositionList acopy = new

问题 I want to make a copy of an array, to modify the copy in-place, without affecting the original one. This code fails a = [ '462664', '669722', '297288', '796928', '584497', '357431' ] b = a.clone b.object_id == a.object_id # => false a[1][2] = 'X' a[1] #66X722 b[1] #66X722 The copy should be different than the object. Why does it act like if it were just a reference? 回答1: You need to do a deep copy of your array. Here is the way to do it Marshal.load(Marshal.dump(a)) This is because you are

问题 I'm uncertain whether this is a platform difference or an implementation difference. I'm hoping that someone can help me shed light on that. Given this code: filesystem::path foo("foo"); filesystem::path bar("bar"); filesystem::create_directories(foo); filesystem::copy(foo, bar); const auto fooftime = filesystem::last_write_time(foo); const auto barftime = filesystem::last_write_time(bar); const auto foocftime = decltype(fooftime)::clock::to_time_t(fooftime); const auto barcftime = decltype

问题 I'm new to C# and Unity, and here I am tweaking and creating my first minigame. Here is the problem: I've got a little cube, that moves. I've implemented a method that checks the next position before making a move. The method receives as parameters the current cube position, and the direction: public bool okToMove(Transform playerCurrentPosition , int directionIndex) { Transform playerNextPosition = playerCurrentPosition; playerNextPosition.Translate(toDirection(directionIndex)); if

问题 We have a database that contains several Trees. These trees are build using the "Preorder tree traversal" principle. This is a very powerful way of creating trees but it has one big disadvantage, adding multiple nodes at once. We have to create a copy function in our tree, copying a single (lowest level) node is very easy, you can do this in one call. But now we want to copy a whole folder at once. We were wondering if we should do this in .net of with a stored procedure. We have to make sure

问题 I am trying to copy NSMutableArray to another but it does not show me anything at the UITableView : NSMutableArray *objectsToAdd= [[NSMutableArray alloc] initWithObjects:@"one",@"two"]; NSMutableArray *myArray = [[NSMutableArray alloc] initWithObjects:objectsToAdd,nil]; NSMutableArray *list = [[NSMutableArray alloc] init]; [self.list addObjectsFromArray:myArray]; Nothing show up! What is wrong? It crashes my app because I do not have nil at my NSMutableArray how can I add nil to it? addobject

问题 This question already has an answer here : scanf Getting Skipped [duplicate] (1 answer) Closed 4 years ago . I'm currently writing a program that will copy or append one file's text into another. My problem comes up when the user is prompted whether they want to overwrite or append the file, scanf() and getchar() are both skipped. I have tried using numerous combinations of getchar()'s and scanf()'s along with fflush(stdin) and ensuring that all the files I had opened are close, but I still

问题 I'm sending a config file for thousands of nodes, because of some customisation there's maybe 5 or 6 paths to that file (There's only one file for host but the path can vary) and there isn't a easy way to figure out the default location with facts. Based on this, I'm looking for some way to set the "dest" of copy module like we can set the "src", with a with_first_found loop. Something like that: copy: src=/foo/{{ ansible_hostname }}/nrpe.cfg dest="{{item}} with_items: - "/etc/nagios/nrpe.cfg
