clone

问题 I often work with Mercurial by keeping a local store of my upstream clones, and then just cloning again locally for my actual working environment: $ cd /clones $ hg clone ssh://external-repo.example.com/some/repo/path/foo $ cd ~/Development $ hg clone /clones/foo This is particularly useful for me because I often want to make new clones on airplanes, etc., where I have no internet access. However, this doesn't work when the original clone contains subrepos - the presence of the .hgsubstate

问题 What are the options to clone or copy a list in Python? While using new_list = my_list , any modifications to new_list changes my_list everytime. Why is this? 回答1: With new_list = my_list , you don't actually have two lists. The assignment just copies the reference to the list, not the actual list, so both new_list and my_list refer to the same list after the assignment. To actually copy the list, you have various possibilities: You can use the builtin list.copy() method (available since

问题 I am cloning a div which includes a datepicker. I have fixed the datepicker when cloned using: // Re-initialize the datepicker $(".datepicker").each(function() { // Remove the class $(this).removeAttr('id').removeClass('hasDatepicker'); // Re-initialize the datepicker $(this).datepicker({ dateFormat: 'yy-mm-dd', changeMonth: true, changeYear: true, yearRange: "-150:+0" }); }); Every change on that datepicker, it computes for the age and outputs the value to the age field. However, the

问题 After reading multiple posts (here's one) about how clone( ) from the ArrayList class is broken, I was wondering no one has re-implemented it so that it isn't broken where people can be more comfortable using the method. Is there something I'm missing here for a reason why no one has re-implemented it so that it is not broken? 回答1: The clone() itself is not broken: it's implemented well according to the specification of the clone() method. The problematic place is this specification itself.

问题 The java util Collections class offers to create an "unmodifiable" decorator around any existing list. But as we all know (or learn the hard way at some point); it is really just a decorator around the list that was originally passed into that call. The decorated list can't be changed; but it will change under the covers if the "original" list is modified. Now assume that I have some class like class Whatever { private final List<IDontCare> someElements; public Whatever(List<IDontCare>

问题 I want to do something like: MyObject myObj = GetMyObj(); // Create and fill a new object MyObject newObj = myObj.Clone(); And then make changes to the new object that are not reflected in the original object. I don't often need this functionality, so when it's been necessary, I've resorted to creating a new object and then copying each property individually, but it always leaves me with the feeling that there is a better or more elegant way of handling the situation. How can I clone or deep

问题 I need to clone a div which when right clicked will show a clone button. I am using this code in editpage.ts to open a context menu with clone button detectRightMouseClick($event) { // disabling the default browser window which comes on right click document.addEventListener('contextmenu', event => event.preventDefault()); if($event.which === 3) { this.rightPanelStyle = {'display':'block','left':$event.clientX + 'px','top':$event.clientY + 'px'}; return false; } } //for clone clone(){ console

问题 I am unable to find a solution for this Table that I am cloning with JQuery. I am able to clone the table and update the ID and NAME properties to avoid html conflicts. The Select drop-down only triggers an event to its JQuery when I use the first (original) copy of the table. However, the cloned version does not trigger the required event that I am using to fill-in the Description Quantity and Price fields. I am posting my Table and JQuery. Can someone please let me know what I am missing to

问题 I was trying to clone a github's repo from RStudio. I have configured git as version control executable. I got this error message: SSL certificate problem: unable to get local issuer certificate. What do I have to do? Thanks 回答1: Are you currently connecting from a corporate network? Some firewall settings have been known to cause issues.

问题 now I'm trying to make a simple drag and drop game. The first time I drag and drop a clone works fine, but it doesn't allow me to drag a clone anymore. So I want to create as many clones as I drag.... and I have no idea how to do it. Please take a look at my code first. function init(){ var xCoordinate; var yCoordinate; var itemName; $('#burger, #chicken, #fries, #hotdog, #soda').draggable({ containment: '#screen', start: getPosition, helper: 'clone', stop: dragStop, revert: 'invalid' }); $('
