vue的Bug解决->[Vue warn]: Error in render: "TypeError: Cannot read property 'XXX' of null"

vue的Bug解决->[Vue warn]: Error in render: "TypeError: Cannot read property 'XXX' of null"
我的这个报错是[Vue warn]: Error in render: "TypeError: Cannot read property 'XXX' of null"是data中的‘XXX’没有获取到
也就是是this.XXList = data.yy没获取到data中的内容
可以尝试改为this.XXList.push( data.yy)
