}

html = html + strli;
}
layui.jquery("#memus").html(html);
layui.element.init(); //一定初始化一次
}
})
});
//添加选项卡
function addTab(name, url) {
if(layui.jquery(".layui-tab-title li[lay-id='" + name + "']").length > 0) {
//选项卡已经存在
layui.element.tabChange('tabDemo', name);
layer.msg('切换-' + name)
} else {
//动态控制iframe高度
var tabheight = layui.jquery(window).height() - 95;
contentTxt = '<iframe src="' + url + '" scrolling="no" width="100%" height="' + (tabheight) + 'PX"></iframe>';
//新增一个Tab项
layui.element.tabAdd('tabDemo', {
title: name,
content: contentTxt,
id: name
})
//切换刷新
layui.element.tabChange('tabDemo', name)
layer.msg('新增-' + name)
}
}
