微信API: wx.openCard

具体实现：从后台拉取卡券id列表；再调用wx.openCard

openWxCard:function(){

let params = {

data: {},

url: xxx

}

wx.ajax(params, "POST").then(res => {

if (res.data.data!=''){

res = res.data.data.map(val => {

return { cardId: val.card_id, code: val.code }

})

wx.openCard({

cardList: res,

success(res) { }

})

}else{

wx.commonJs.tip('您的卡包为空!', 'none')

}

}).catch(res => {

wx.commonJs.tip('打开卡包失败', 'none')

})

},
