Append div to end of document with jQuery?
提问by Vivian River
I would like to write a function using jQuery to append a div
to the end of a web page. I would like to be able to use the function on many different pages.
我想使用 jQuery 编写一个函数来将 a 附加div
到网页的末尾。我希望能够在许多不同的页面上使用该功能。
I've written the following code, but it doesn't work:
我已经编写了以下代码,但它不起作用:
$(document).append('<div id="helloDiv"></div>');
$('#helloDiv').html('hello'); // does nothing
$('#helloDiv').css('top','100') // throws an error
How do I fix this?
我该如何解决?

It is meaningless to append to the document
. Append to the document's body
node instead, since this is where all the visible content is:
附加到document
. 改为附加到文档的body
节点,因为这是所有可见内容所在的位置:
$(document.body).append('<div id="helloDiv"></div>');

If you want it to be at the end of the body
, why not use:
如果您希望它位于 的末尾body
,为什么不使用:
$('body').append('<div id="helloDiv"></div>');
$('#helloDiv').html('hello');
$('#helloDiv').css('top', 100);
However, just .css('top', 100)
does not do much unless you set the position
to absolute
.
然而,只是.css('top', 100)
并没有做太多,除非你设定的position
到absolute
。

Try:
尝试:
$('body').append('<div id="helloDiv"></div>');
$('#helloDiv').html('hello');
$('#helloDiv').css('top', '100');
Or just add the content and it's css before adding the div.
或者只是在添加 div 之前添加内容和它的 css。
var $newdiv = '<div id="helloDiv">hello</div>';
$('body').append($newdiv);
