picker-view能否设置每个项目是否可选，如果不可选择，则跳转到可选择的项目：

<picker-view indicator-style="height:40px" style="width:100%;height:200px" value="{{pickerViewValue}}" bindchange="selectBookTime">
    <picker-view-column>
        <view wx:for="{{bookDateArr}}" class="pickerView {{index == 2 ? 'pickerViewDisabled' : ''}}" style="line-height:40px">{{item}}</view>
    </picker-view-column>
    <picker-view-column>
        <view wx:for="{{bookTimeArr}}" class="pickerView" style="line-height:40px">{{item}}</view>
    </picker-view-column>
</picker-view>
