<text class="feed_content top_5" data-id="{{item.userInfo.userId}}" data-name="{{item.userInfo.nickname}}" catchtap="replyContent">{{item.content}}</text>


<view class="row feed_comment_container center_h">
<input class="feed_comment_input" value="{{content}}" bindblur="loseFocus" focus="{{focus}}" bindinput="bindContent" placeholder-class="feed_comment_placeholder" placeholder="写点评论吧......" />
    <view class="row center feed_comment_button" catchtap="createContent">

    </view>
</view>

replyContent(e) {
    let replyUserId = e.currentTarget.dataset.id;
    let replyNickName = e.currentTarget.dataset.name;
    console.log(replyUserId+'---->'+replyNickName)
    this.setData({
        focus:true,
        replyUserId,
        replyNickName
    })
}

走replyContent方法后，设置focus为true，并没有获取焦点，刚进来的时候，设置为true 也没有自动获取焦点，是我写的有问题么？

请各位大佬指点
