jQuery：如何在HTML文件的末尾添加div？

Question

I saw in the documentation that .append allows you to add things to an element. But I want to end a div right before the </body> tag

Answer 1

You can use this:

$('body').append('<div>footer</div>');

but also this:

$('<div>footer</div>').appendTo('body');

or this:

$('body').html($('body').html()+'<div>footer</div>');

Reference with differences here: http://api.jquery.com/appendTo/

Answer 2

$('body').append('<div />');

Answer 3

等等，为什么这不起作用？

$("body").append('<div id="your_div" />');
