$(".one > li").each(function(){
// 打印出所有li的内容
console.log($(this).text());
})

<li>44d</li>
<li>5555</li>
</ul>
<script>
// 2种 通过each遍历li 通过$(this)给每个li加事件
$('.two > li').each(function(index) {
console.log(index +":" + $(this).text());
// 给每个li加click 点那个就变颜色

<li>Eat</li>
<li>Sleep</li>
<li>3种</li>
</ul>
<span>点击3</span>
<script>
// 4种 遍历所有li 给所有li添加 class类名
$('span').click(function(){
$('.ctn3 > li').each(function(){
$(this).toggleClass('example');
})
