通过jQuery，HTML，CSS随机移动divs

Question

我正在创建一个游戏，您必须关注粒子（Divs），然后单击它们“吃”它们。我目前遇到的问题是，我找不到一种克隆每个div的方法，并给它一个随机的x和y坐标值以将其定位。

这是我的代码：

var x = e.pageX;
var y = e.pageY;

function reposition(div, x, y, randomMode) {

      if(randomMode == 1) {
        x = Math.floor(Math.random() * 990);
        y = Math.floor(Math.random() * 560);
      }

      $(div).animate({"left": x + "px"}, "slow");
      $(div).animate({"top": y + "px"}, "slow");
    }

    // need to find some way to duplicate the divs and move them in random directions

    setInterval(function() {
            for(var i = 1; i < 4; i++) {

              reposition("#grabItem", 0, 0, 1);
            }
          }, 2000);

Answer 1

//select all grab items, and since there will be multiple particles
//use a class to mark them, not an ID. This line is to capture all
//particles existing in the markup, that are not dynamically added later
var $particles = $('.grabItem');
//set your container that has all the particles
var $container = $('body');

//every two seconds add a new particle at random location
setInterval(function() {
   for(var i = 1; i < 4; i++) {
      $particles.add(CreateParticle());
      MoveParticles();
   }
}, 2000);

//creates a new particle and adds to the canvas
function CreateParticle(){
   return $('<div/>').addClass('grabItem').appendTo($container);
}

//randomly moves all the particles around
function MoveParticles() {
   $particles.each(function() {
      var x = Math.floor(Math.random() * 990);
      var y = Math.floor(Math.random() * 560);

      $(div).animate({"left": x + "px"}, "slow");
      $(div).animate({"top": y + "px"}, "slow");
   });
}

这将每两秒在随机位置添加一个新粒子，并移动所有现有粒子（包括新粒子）。如果您需要精确的克隆方法，请查看 jQuery 的 .clone() 方法。

jQuery 中有一个 Clone 方法，它是您正在寻找的吗？
