小程序动态添加class及调接口传递多个参数
1.动态添加class
<view class="step2 {{indication == 2 ?'on':''}}">
<view class='tc left'>
<view>喷洒泡沫</view>
<view>(min)</view>
</view>
<view class='right'>{{foam}}</view>
</view>
2.传递多个参数
第一个参数用的是? 后面用的是& ?orderid=' + e.currentTarget.dataset.orderid
<view class="btn-area" bindtap='carWashOrder' data-washing="{{washing}}" data-foam="{{foam}}" data-cleaner="{{cleaner}}" data-all_money="{{all_money}}" data-orderid='{{orderid}}'>
carWashOrder:function(e){ var that = this; wx.navigateTo({ url: '/pages/carWashOrder/carWashOrder?orderid=' + e.currentTarget.dataset.orderid + "&washing=" + e.currentTarget.dataset.washing + "&foam=" + e.currentTarget.dataset.foam + "&cleaner=" + e.currentTarget.dataset.cleaner , }) }
3.请求接口成功 页面渲染一定要加that.setData({})
var parma = { orderid: that.data.orderid, token: app.globalData.token , off_on: that.data.off_on } // ajax app.requsetUrl('/Order/settlement', parma, function (res) { if(res.data.code == 1){ console.log(JSON.stringify(res)) that.setData({ all_money: that.data.all_money//结算金额 }) } })
