iframe的使用方法
<!DOCTYPE html>
<html>
<head>
<title>欢迎</title>
<link rel="stylesheet" type="text/css" href="/static/plugins/layui/css/layui.css">
<script type="text/javascript" src="/static/plugins/layui/layui.js"></script>
<style type="text/css"> </style>
</head>
<body>
<!--header-->
<div class="header">
<span class="title">后台管理系统</span>
<span class="userinfo">{$admin.username}【{$role.title}】<a href="javascript:;" onclick="logout()">退出</a></span>
</div>
<!--menu-->
<div class="menu" id="menu">
<div class="layui-collapse" lay-accordion>
{volist name="$menus" id="vo"}
<div class="layui-colla-item">
<h2 class="layui-colla-title">{$vo.title}</h2>
<div class="layui-colla-content">
<?php if(isset($vo['children']) && $vo['children']){?>
<ul class="layui-nav layui-nav-tree">
{volist name="vo.children" id="cvo"}
<li class="layui-nav-item"><a href="javascript:;" onclick="menufire(this)" src="/index.php/admins/{$cvo.controller}/{$cvo.method}">{$cvo.title}</a></li>
{/volist}
</ul>
<?php }?>
</div>
</div>
{/volist}
</div>
</div>
<!--主操作区-->
<div class="main">
<iframe src="/index.php/admins/home/welcome" onload="resetMainHeight(this)" style="width: 100%;height: 100%;" frameborder="0" scrolling="0"></iframe>
</div>
</body>
</html>
<script type="text/javascript">
layui.use(['element','layer'], function(){
var element = layui.element;
$ = layui.jquery;
layer = layui.layer;
resetMenuHeight();
});
// 重新设置页面高度
function resetMenuHeight(){
var height = document.documentElement.clientHeight - 50;
$('#menu').height(height);
}
// 重新设置主操作区高度
function resetMainHeight(obj){
var height = parent.document.documentElement.clientHeight - 53;
$(obj).parent('div').height(height);
}
// 菜单点击
function menufire(obj){
// 获取url
var src = $(obj).attr('src');
// 设置iframe的src
$('iframe').attr('src',src);
}
// 退出登录
function logout(){
// 退出前确认
layer.confirm('确定要退出吗？',{
icon:3,
btn:['确定','取消']
},function(){
$.get('/index.php/admins/account/logout',function(res){
if(res.code>0){
layer.msg(res.msg,{'icon':2});
}else{
layer.msg(res.msg,{'icon':1});
setTimeout(function(){window.location.href='/index.php/admins/account/login';},1000);
}
},'json');
});
}
</script>通过iframe标签就设置操作区域,然后通过改变iframe里面的url地址就可以切换页面;
//重点;
function menufire(obj){
var src = $(obj).attr('src');
$('iframe').attr('src',src);
}
