小程序用的iview组件，想把tab点击事件区域变大 想把事件移到顶部，发生了错

<view class=“i-class i-tabs-tab {{ scroll ? ‘i-tabs-tab-scroll’ : ‘’ }} {{ current ? ‘i-tabs-tab-current’ : ‘’ }}” bindtap=“handleClickItem”>

    <i-badge dot=“{{ dot }}” count=“{{ dot ? 0 : count }}”>

        <view >

            <view class=“i-tabs-tab-title {{ current ? ‘i-tabs-tab-title-current’ : ‘’ }}” wx:if=“{{ current && currentColor }}” style=“color: {{ currentColor }}”>{{ title }}</view>

            <view class=“i-tabs-tab-title {{ current ? ‘i-tabs-tab-title-current’ : ‘’ }}” wx:else>{{ title }}</view>

        </view>

    </i-badge>

    <view class=“i-tabs-tab-bar” wx:if=“{{ current }}” style=“background: {{ currentColor }}”></view>

</view>

爆出了错误
