<text>微信支付</text>
</view>
<view catchtap="offline_pay" class="offline_pay">
<i class="icon {{payment_mode==0?'active':''}}" type="String"></i>
<text>对公打款</text>
</view>
<block wx:if="{{balance!=0}}">
<view catchtap="wallet_pay" class="wallet_pay">
<i class="icon {{payment_mode==2?'active':''}}" type="String"></i>
<text>钱包支付(余额:{{balance/100}}元)</text>

</view>
</block>
</view>
