登陆前后导航栏处理2015-12-12
注意：添加灰色背景处，关于Ajax传值，和js的判断
1 登陆后控制器处理：判断是否登陆并传递用户信息
classIndexControllerextendsHomeBaseController {//登录publicfunctionindex() {$id=I("get.id");$users_model=M("Users");$user=$users_model->where(array("id"=>$id))->find();if(empty($user)){$this->error("查无此人！");
}$this->assign($user);$this->display(":index");
}functionis_login(){if(sp_is_user_login()){$this->ajaxReturn(array("status"=>1,"user"=>sp_get_current_user()));}else{$this->ajaxReturn(array("status"=>0,"info"=>"此用户未登录！"));
}
}
。。。。。。
2 登陆前后主页导航栏的 登陆和未登录 的显示
<divid="main-menu-user"><!--还未登陆--><divclass='useroutuser'><ulclass="nav navbar-nav navbar-right"><li><ahref="{:u('user/register/index')}"data-toggle="dropdown">注册</a></li></ul><ulclass="nav navbar-nav navbar-right"><li><ahref="{:u('user/login/index')}"data-toggle="dropdown">登陆</a></li></ul><ulclass="nav navbar-nav navbar-right"style="margin-top:10px"><li><imgsrc="__TMPL__/Public/img/headicon.png"class="headicon"/></li></ul></div><!--已经登陆--><divclass="userlogin user"><ulclass="nav navbar-nav navbar-right"><li><ahref="{:u('user/index/logout')}"data-toggle="dropdown">退出</a></li></ul><ulclass="nav navbar-nav navbar-right"><li><ahref="{:u('user/center/index')}"data-toggle="dropdown"class="user-nicename"></a></li></ul><ulclass="nav navbar-nav navbar-right"style="margin-top:10px"><li><imgsrc=""class="headicon"/></li></ul></div></div>
3 登陆后，js对box的操作
<script>
$(function() {/*控制导航栏显示登陆还是个人中心*/$.post("{:U('user/index/is_login')}",{},function(data){if(data.status==1){if(data.user.avatar){$("#main-menu-user ul li .headicong").attr("src",data.user.avatar.indexOf("http")==0?data.user.avatar:"__UPLOAD__avatar/"+data.user.avatar);
}
$("#main-menu-user ul li .user-nicename").text(data.user.user_nicename!=""?data.user.user_nicename:data.user.user_login);$("#main-menu-user .userlogin").show();
$("#main-menu-user .userout").hide();
}if(data.status==0){
$("#main-menu-user .userout").show();
$("#main-menu-user .userlogin").hide();
}
}); });</script>
