function addTab(title, href,icon){var tt = $('#tabs');if (tt.tabs('exists', title)){//如果tab已经存在,则选中并刷新该tab            tt.tabs('select', title);        refreshTab({tabTitle:title,url:href});} else {    if (href){    var content = '<iframe scrolling="no" frameborder="0"  src="'+href+'" style="width:100%;height:100%;"></iframe>';    } else {    var content = '未实现';    }    tt.tabs('add',{    title:title,    closable:true,    content:content,    iconCls:icon||'icon-default'    });}}/**     * 刷新tab * @cfg  *example: {tabTitle:'tabTitle',url:'refreshUrl'} *如果tabTitle为空，则默认刷新当前选中的tab *如果url为空，则默认以原来的url进行reload */function refreshTab(cfg){var refresh_tab = cfg.tabTitle?$('#tabs').tabs('getTab',cfg.tabTitle):$('#tabs').tabs('getSelected');if(refresh_tab && refresh_tab.find('iframe').length > 0){var _refresh_ifram = refresh_tab.find('iframe')[0];var refresh_url = cfg.url?cfg.url:_refresh_ifram.src;//_refresh_ifram.src = refresh_url;_refresh_ifram.contentWindow.location.href=refresh_url;}}
