                    id:id,
                    title: task, 
                    closable: true,
                    iconCls: 'Feed',
                    html: '<iframe src="'+href+'" scrolling="auto" frameborder="0" width="100%" height="100%"></iframe>' 
                    });                                         
                parent.Ext.getCmp("myTabPanel").setActiveTab(id);
            }           
    </script>

配置id，判断存在就激活，否则在添加

    function addTab(href) {
        var id = parseInt(href.substr(31, 6));
        if (Ext.getCmp(id)) { tab.setActiveTab(id); return}/////////
        var task = href.substr(26, 11);
        parent.Ext.getCmp("myTabPanel").add({
            id: id,
            title: task,
            closable: true,
            iconCls: 'Feed',
            html: '<iframe src="' + href + '" scrolling="auto" frameborder="0" width="100%" height="100%"></iframe>'
        });
        parent.Ext.getCmp("myTabPanel").setActiveTab(id);
    }
