来自div的Javascript拷贝和符号输入故障

I cannot find an answer to this question...

The problem. Javascript copying text from DIV to input (textbox), fails to copy & as &, and copies it as &. See code plus example.

I have the following code (on different pages, just to simplify I put all here):

INPUT where I want the text copied.

<input name="artist" id="txtArtist" type="text" placeholder="Introduce the artist" />

DIV where the text is copied from. This data is populated from a SQL database.

<div id="art0"><div onclick="copyText(0)">Mumford & Sons</div></div>'

The function that fails...

function copyText(rowID){
    var content = document.getElementById('art'+rowID).innerHTML.replace(/<\/?[^>]+(>|$)/g, "
");
    document.getElementById("txtArtist").value = document.getElementById('art'+rowID).innerHTML;
    document.getElementById("txtArtist").value = content;
}

EXPECTED result inside textbox: Mumford & Sons

ACTUAL result inside textbox: Mumford & Sons

Any help please?

Thank you all!!

Use .textContent instead of .innerHTML:

var content = document.getElementById('art'+rowID).textContent;

Note that .textContent is not supported by IE 8 and lower, so if you are so unfortunate, test for and use .innerText instead.

var prop = 'textContent' in document.body ? 'textContent' : 'innerText',
    content = document.getElementById('art'+rowID)[prop];
