jquery 怎么获取当前点击class 是第几个

一、如果是同级（兄弟元素）的，如：

<ul><li class='a'></li><li class='a'></li></ul>可以

$("a")click(function(){

var a=$(this)index;

//或者

var a=$('a')index(this);

}

二、而对于不同级（非兄弟元素），如：

<div class='a'></div>

<div><div class='a'></div></div>

则只能这样

$("a")click(function(){

var a=$('a')index(this);

}

注意事项

jQuery 拥有若干进行 CSS *** 作的方法。

1、addClass() - 向被选元素添加一个或多个类

2、removeClass() - 从被选元素删除一个或多个类

3、toggleClass() - 对被选元素进行添加/删除类的切换 *** 作

4、css() - 设置或返回样式属性

例如：

important

{

font-weight:bold;

font-size:xx-large;

}

blue

{

color:blue;

}

向不同的元素添加 class 属性。当然，在添加类时，也可以选取多个元素：

实例：

$("button")click(function(){

$("h1,h2,p")addClass("blue");

$("div")addClass("important");

});

function fmt(date){

var d = new Date(date)

return `${agetMonth()+1}-${agetDate()}`

}

这个是脚本的编法。

其实脚本的模拟时间60进一位前面那些符号只要整对，还是很简单的，可以直接去网上找这个模板，直接在里面修改时间这块就可以。不用自己全部编辑的。

你的意思是你要获取到点击a对应的父元素li的tips属性对吗？

可以使用parent获取到父元素，然后用attr获取到属性，代码如下：

<script src="jquery-171minjs"></script>

<script>

$(document)ready(function(){

$("a")click(function(){

var tips = $(this)parent("li")attr("tips");

alert(tips);

});

});

</script>

<ul>

    <li tips="您好"><a href="javascript:void(0)">点击</a></li>

    <li tips="再见"><a href="javascript:void(0)">点击</a></li>

</ul>
