分享js实现，，是否确认删除，如果“否”，则返回，如果“是”，则删除
刚学习jsp，通过servlet已经初步实现点击“删除”按钮，即可实现删除这条数据，现在想增加一个功能，就是点击“删除”按钮，弹出”是否确认删除“，如果“否”，则返回，如果“是”，则删除,就是删除按钮的onclick点击时，如果选择否，则不跳转后面的location，求大神支招

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
