jquery的引入方式与简写方式——2018年4月2日

一、jquery的两种引入方式

1.外部cdn引用

只需要复制cdn地址即可

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

2.本地导入

按本地路径导入即可

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

二、简化写法

$(document).read(function){

$('li')[1].style.backgroundColor = 'skyblue'

}

等同于 $(function(){

$('li')[1].style.backgroundColor  = 'skyblue'

)}

——对比与原生写法

var li = document.getElementByTageName('li')

li[1].style.backgroundColor = 'skyblue'
