克隆所选元素 [英] Clone selected element

问题描述

我正在工作一个简单的应用程序，该应用程序可在元素内移动元素. 代码工作正常，我只想克隆一个圆圈，以便可以将相同的元素放在不同的盒子上.

I'm working a simple app that move an element inside an element. The code is working fine, I just want to make a clone of the circles so that I can place same element on different boxes.

我尝试添加此行

$( selectedChip ).clone().after( selectedChip );

这样，每次我单击正方形时，都会插入clone元素，而原始元素会保留.

so that every time I click on the squares the clone element will be inserted and the original stays.

希望你能帮助我.

谢谢.

var selectedCircle = null;

$(".circle").click(function() {
    $(this).addClass('selected').siblings().removeClass('selected').animate({ top: 0, left: 0 });
    selectedCircle = $(this);
});

$(".container .square").click(function() {
  // $( selectedChip ).clone().after( selectedChip );
  if (selectedCircle) {
    var selectedSquare = $(this);
    selectedSquare.addClass("selected");

    var xOffset = (selectedSquare.width() - selectedCircle.width()) / 2;
    var yOffset = (selectedSquare.height() - selectedCircle.height()) / 2;

    selectedCircle.animate({
      top: selectedSquare.offset().top - selectedCircle.offset().top + yOffset,      
      left: selectedSquare.offset().left - selectedCircle.offset().left + xOffset
    }, 1200);
  }

$(".circle").click(function() {
  $(this).addClass('selected').siblings().siblings('.clone').remove();
  $(this).addClass('selected').siblings().removeClass('selected').animate({
    top: 0,
    left: 0
  });
  selectedCircle = $(this);
});

$(".container .square").click(function() {

  if (selectedCircle) {
    var selectedSquare = $(this);
    debugger;
    var selectedCircleClone = selectedCircle.clone().addClass("clone");
    selectedCircle.after(selectedCircleClone);

    selectedSquare.addClass("selected");

    var xOffset = (selectedSquare.width() - selectedCircleClone.width()) / 2;
    var yOffset = (selectedSquare.height() - selectedCircleClone.height()) / 2;

    selectedCircleClone.animate({
      top: selectedSquare.offset().top - selectedCircleClone.offset().top + yOffset,
      left: selectedSquare.offset().left - selectedCircleClone.offset().left + xOffset
