vue新手，求各位大神指教。

如何获取选中的数据并提交？

Answer 1

好像是直接循环遍历answerInfo获取里面的singlechoice_default和multichoice_default就可以了。。。

呵呵，好丢人，捂脸-_-||

Answer 2

change事件吧item传出来
或者看文档提供事件没有

Answer 3

<RadioGroup @on-change="handleChange()" v-if="item.questionType == '单选题'" v-model="answerInfo[index].singlechoice_default" vertical>
</RadioGroup>

method里面handleChange(val)取val

Answer 4

可以使用楼上的on-change 或者直接在watch中监听answerInfo
