要使用jQuery就需要先引入jQuery,引入jQuery有两种方法:

1,本地引入,把jquery文件放在本地,通过src直接引入本地文件(本人喜欢此种方式):

<script type="text/javascript" src="../js/jquery-3.3.1.js"></script>


2,CDN方式引用,直接引入互联网上的文件,引入方式如下:

<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>


作业之二:$(document).ready()如何使用:

$(document).ready(function(){

$('#list > li').addClass('horiz')

})


简写方式:

$(function(){

$('#list > li').addClass('horiz')

})


Correction status:qualified
