实现一堆按钮没有给ID,当被点击时获得响应事件,修改样式,本文使用的是jquery-3.3.1。

<script src="../jquery-3.3.1.min.js"></script>
<style media="screen">
.btn {

weight:50px;
}
.btn-info{
background:#fff;

.btn-inverse{

<body>
<p id="btn_group">
<button class="btn btn-info" ">昨天</button>
<button class="btn btn-info" ">今天</button>
<button class="btn btn-info" ">上周</button>
<button class="btn btn-inverse" ">上个月</button>
<button class="btn btn-info" ">自定义</button>
</p>
<script type="text/javascript">
$("#btn_group>:button").click(function(){
$("#btn_group>:button").each(function ()
{
$(this).prop("className", "btn btn-info");

this.className = "btn btn-inverse";
