推荐答案

您正在创建一个无限递归！

You are creating an infinite recursion!

function duplicate()
{
    var div = duplicate("div");

函数一遍又一遍地调用它。使用 cloneNode（） ：

The function is calling itself over and over again. Use cloneNode():

HTML：

<div id="duplicater0"> 
duplicate EVERYTHING INSIDE THIS DIV
</div>

JavaScript：

JavaScript:

var i = 0;

function duplicate() {
    var original = document.getElementById('duplicater' + i);
    var clone = original.cloneNode(true); // "deep" clone
   clone.id = "duplicater" + ++i; // there can only be one element with an ID
    clone.onclick = duplicate; // event handlers are not cloned
    original.parentNode.appendChild(clone);
}

工作DEMO

或不带ID：

function duplicate() {
    var clone = this.cloneNode(true); // "deep" clone
    clone.id = ""; // there can only be one element with an ID
    clone.onclick = duplicate; // event handlers are not cloned
    this.parentNode.appendChild(clone);
}

更新：

如果您希望在点击按钮时克隆div，可以使用稍微不同的版本：

If you want to clone the div on button click, you can use a slightly different version:

HTML：

<button id="button" onlick="duplicate()">Click me</button>
<div id="duplicater"> 
    duplicate EVERYTHING INSIDE THIS DIV
</div>

JavaScript：

JavaScript:

var i = 0;
var original = document.getElementById('duplicater');

function duplicate() {
    var clone = original.cloneNode(true); // "deep" clone
    clone.id = "duplicater" + ++i;
    // or clone.id = ""; if the divs don't need an ID
    original.parentNode.appendChild(clone);
}

如果您不在表单中，则应使用< button> 而不是< input type =button> 。

If you are not in a form, you should use <button> instead of <input type="button">.
