我有一个拖放程序，代码在下面。现在，我已经尝试了一段时间让我的'模拟到下一轮！'取.node7，.node8，.node9，.node10，.node11和＆amp;某些.node12的{{1}}个ID，并随机为每列或“团队”分配一个。什么都有帮助！这是一个JSFiddle，这是一个片段：

答案 0 :(得分：2)
暗示您将id="Available Players"更改为id="AvailablePlayers"，这应该有效：
function shufflePlayers(amount=6) {
var box = 1;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*$('#AvailablePlayers li').length));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#box'+box);
if(box == 6) {
box = 1;
} else {
box++;
}
}
}
编辑：修正了能够随机播放＆gt; 6位玩家的功能，还将声明移到了循环之外。
编辑2 ：这是一个接受团队容器ID数组作为参数的版本：
function shufflePlayers(amount=6, teamsID=['box1', 'box2', 'box3', 'box4', 'box5', 'box6']) {
var box = 0;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*$('#AvailablePlayers li').length));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#'+teamsID[box]);
if(box == teamsID.length) {
box = 0;
} else {
box++;
}
}
}
按原样，此修改后的函数将在没有任何参数的情况下工作，但如果更改团队框ID，则需要将它们作为数组传递：shufflePlayers(6, ['Red', 'Green', 'Blue', 'Cyan', 'Magenta', 'Yellow'])
编辑3：该功能的另一个版本，这次它只从第一组中挑选随机玩家，大小为amount（默认为6）。
function shufflePlayers(amount=6, teamsID=['box1', 'box2', 'box3', 'box4', 'box5', 'box6']) {
var box = 0;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*(amount-i)));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#'+teamsID[box]);
if(box == teamsID.length) {
box = 0;
} else {
box++;
}
}
}
