Differences between jquery append () and html () methods, jqueryappend
Append (content): The method inserts the specified content at the end of the selected element (still inside). Many friends think that append is similar to html, in other words, append is added based on the original content, while in html, it replaces all the current content.

$ (Selector). append (content)
Add content using functions
Use a function to insert content at the end of a specified element.
Syntax
$ (Selector). append (function (index, html ))
Instance code:
<script src="/jquery.min.js" type="text/javascript"></script><style>.imgFocus{border: 1px solid #eee;}</style><p> </p><script type="text/javascript">var showimg = "<div class='imgFocus'>123456</div>";$("p").append(showimg);</script>
The html () method returns or sets the content of the selected element (inner HTML ).
If no parameter is set for this method, the current content of the selected element is returned.

When this method is used to return a value, it returns the content of the First Matching Element.
