append(content)
向每個(gè)匹配的元素內(nèi)部追加內(nèi)容。
這個(gè)操作與對(duì)指定的元素執(zhí)行appendChild方法，將它們添加到文檔中的情況類似。
--------------------------------------------------------------------------------
Append content to the inside of every matched element.
This operation is similar to doing an appendChild to all the specified elements, adding them into the document.
返回值
jQuery
參數(shù)
content (String, Element, jQuery) : C要追加到目標(biāo)中的內(nèi)容
示例
向所有段落中追加一些HTML標(biāo)記。
HTML 代碼:
<p>I would like to say: </p>
jQuery 代碼:
$("p").append("<b>Hello</b>");
結(jié)果:
[ <p>I would like to say: <b>Hello</b></p> ]

--------------------------------------------------------------------------------------------------------------------------------------------------
appendTo(content)
把所有匹配的元素追加到另一個(gè)、指定的元素元素集合中。
實(shí)際上，使用這個(gè)方法是顛倒了常規(guī)的$(A).append(B)的操作，即不是把B追加到A中，而是把A追加到B中。
--------------------------------------------------------------------------------
Append all of the matched elements to another, specified, set of elements.
This operation is, essentially, the reverse of doing a regular $(A).append(B), in that instead of appending B to A, you're appending A to B.
返回值
jQuery
參數(shù)
content (String) :用于被追加的內(nèi)容

--------------------------------------------------------------------------------------------------------------------------------------------------

Prepend content to the inside of every matched element.
This operation is the best way to insert elements inside, at the beginning, of all matched elements.
