将div1的内容放入div2 onclick事件

Question

I have two divs as follows:

<div id='div1'>
    <p>Hello world!</p>
</div>

<div id='div2'>

</div>

<a id='test' href='javascript:void()'>Click me to fill in div2</a>

I have been wondering what should be the best way to fill in div2 with the content of div1 onclick using jquery in order to have

<div id='div1'>
        <p>Hello world!</p>
    </div>

Answer 1

使用.contents() .clone()和.append()将$("#div1")的内容克隆到$("#div2") .append() ：

$("#div2").append($("#div1").contents().clone());

Answer 2

Rather than resorting to serialising to HTML and then applying that to the other element, as Andy's answer does , it would be nicer to clone the nodes.

$('#test').click(function(e) {
    e.preventDefault();
    $('#div1').contents().clone(true).appendTo('#div2');
});

This has the advantage that any data or events on the elements cloned will continue to exist on the new elements. Since I've used e.preventDefault() , you can also lose the javascript:void bit of your code, because the link's default action has been prevented.

See the jQuery API:

• contents
• clone
• appendTo
• event.preventDefault

Answer 3

$('#div2').html($('#div1').html());
