.insertAfter or .append to an Element Id with Javascript. it's a script tag so it can't be with $
提问by l3ny
I want to add a script after a div, this is what I have:
我想在 div 后添加一个脚本，这就是我所拥有的：
<div id="uno">insert after this</div><br />
<p>this is a paragraph</p><br />
<div>this is a div</div>
var myscript = document.createElement('script');
myscript.setAttribute('src', 'Scripts/start.debug.js');
document.body.appendChild(myscript);
and this code will ad <script src="Scripts/start.debug.js"></script>at the end of the page, and i need it after div #uno. What can I use instead of document.body.appendChild?
并且此代码将<script src="Scripts/start.debug.js"></script>在页面末尾进行广告，我在 div 之后需要它#uno。我可以用什么代替document.body.appendChild？

<script>
// This function inserts newNode after referenceNode
function insertAfter( referenceNode, newNode )
{
referenceNode.parentNode.insertBefore( newNode, referenceNode.nextSibling );
}
insertAfter(document.getElementById("uno"), newScript);
</script>
Even if a nextSibling doesn't exist in the DOM it will still work "because when the second parameter of insertBefore is null then the newNode is appended to the end of the parentNode". A great description can be found here: http://www.netlobo.com/javascript-insertafter.html.
即使 DOM 中不存在 nextSibling 它仍然可以工作，“因为当 insertBefore 的第二个参数为 null 时，newNode 会附加到 parentNode 的末尾”。可以在这里找到一个很好的描述：http: //www.netlobo.com/javascript-insertafter.html。
