如何复制div onclick事件? [英] How can I duplicate a div onclick event?

问题描述

我希望在单击按钮时复制div.我虽然是这样的；但它不起作用.谁能帮我吗?

I want a div to be duplicated when a button is clicked. I though something like this; but it's not working. Can anyone help me?

HTML

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

JAVASCRIPT

JAVASCRIPT

function duplicate()
{
var div = duplicate("div");
    div.id = "duplicater";
div.appendChild(duplicate("duplicater"));
}

推荐答案

您正在创建无限递归！

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

该函数一遍又一遍地调用自己.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);
}

或者没有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:

如果要在单击按钮时克隆div，则可以使用稍有不同的版本:

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

HTML:

<button id="button" onclick="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">.
