    //creating div  
var div = document.createElement('div');
div.innerHtml = '';
document.body.appendChild(div);
div.classList.add('main');

//creating divsec 
var divsec = document.createElement('div');
divsec.innerHtml = '';
document.body.appendChild(divsec);
divsec.classList.add('submain');

//creating array for words
var arr = prompt("Write your word or sentance here and don't accept your apponent to see that!");
array = arr.split('');
array = array.sort();
console.log(array);
alert("Let's construct the word!");

var main = document.getElementsByClassName('main');
var divsec = document.getElementsByClassName('submain');
for(var i = 0; i < arr.length; i++){
    var button = document.createElement('button');
    divsec[0].appendChild(button);
    button.innerHTML = array[i];
    button.onclick = function(){
        mainp = main[0].appendChild(this);
        mainp.onclick = function (){
            divsec[0].appendChild(this);
        }
    }
}

如果不是,请澄清您的问题并举例说明单击单个按钮所需的效果。我也不确定退出该功能是什么意思。我觉得还不错。

你说你需要一个按钮来移动,但你没有说明它需要如何移动。
