微信小程式：bindtap方法傳參

1、wxml

<view bindtap="pay_again" data-name="{{orderList.jid}}" data-fee="{{orderList.act_fee}}" data-mobile="{{orderList.p_phone}}" data-act="{{orderList.act_name}}" class="operating f_r webkit-box" style="line-height:30px;"> 
          <a href="" class="pay bg_red">繼續支付</a> 
      </view>

2、js

  // 再次發起支付請求，呼叫後臺PHP
  pay_again:function(e){
    var that = this;
    that.setData({
      jid: e.currentTarget.dataset.name,
      act_name: e.currentTarget.dataset.act,
      act_fee: e.currentTarget.dataset.fee,
      mobile: e.currentTarget.dataset.mobile
    })
    console.log('活動訂單id = ' + that.data.mobile);
  }
