a href="#"慎用

今天使用ajax异步请求成功之后 发现页面跳转会首页

当且页面地址是http://localhost:8080/sms/ComponentController/findCompntWithFieldList.do?compntCode=ddd

 

ajax请求成功后 跳转到http://localhost:8080/sms/#

 

仔细查找之后发现是<a href="#" onclick="">a标签的问题 

我原先通过点击a触发事件ajax调用   成功之后 执行href=“#”进行地址拼接 http://localhost:8080/sms/#然后就是跳转回了首页
