1、错误描述

Uncaught TypeError: Cannot read property 'attr' of undefined

2、错误原因

$(function(){
         $("#tabs").tabs({
    	active:1,
    	activate: function(event, ui){
    	     var ids = ui.newHeader.attr("id");
    	     console.info(ids);
    	}
        });
    });

jquery UI中ids获取的方式ui.newHeader.attr("id")是accordion获取id的方式，而不是tabs获取id的方式

3、解决办法

$(function(){
         $("#tabs").tabs({
    	active:1,
    	activate: function(event, ui){
    	     var ids = ui.newPanel.attr("id");
    	     console.info(ids);
    	}
        });
    });

var ids = ui.newPanel.attr("id");是tabs获取id的方式

Uncaught TypeError: Cannot read property 'attr' of undefined
