 <view class="slidewrap">
 <text class="s-con" data-id="{{v.id}}" bindtap="minusCount">-</text>
 <slider class="slide" bindchange="sliderchange" step="10" value="{{v.value}}" data-id="{{v.id}}" max="{{v.max}}" min="0" wx:if="{{index<3}}" />
 <slider class="slide" bindchange="sliderchange" step="10" value="{{v.value}}" data-id="{{v.id}}" max="{{v.max}}" min="0" wx:if="{{index==3}}" />
 <text class="s-con" data-id="{{v.id}}" data-max="{{v.max}}" bindtap="addCount">+</text>

Page({
 data: {
 controls: [
 {
 id: 1,
 name: '功能一',
 value: 30,
 max: 60
 },
 {
 id: 2,
 name: '功能二',
 value: 30,

 value: 30,
 max: 60
 },
 {
 id: 4,
 name: '功能四',
 value: 50,
 max: 100
 }
 ]
 },
 
 // 控制加
 addCount: function (event) {
 let data = event.currentTarget.dataset
 let controls = this.data.controls
 let control = controls.find(function (v) {
 return v.id == data.id
 })
 let control1 = controls.find(function (v) {
 return v.max == data.max
 })
  
 if (control.value > control1.max)
 return
 control.value += 10;
 this.setData({
 'controls': controls
 })
 },
 // 控制减
 minusCount: function (event) {
 let data = event.currentTarget.dataset
 let controls = this.data.controls
 let control = controls.find(function (v) {
 return v.id == data.id
 })
 if (control.value <= 0)
 return
 control.value -= 10;
 this.setData({
 'controls': controls
 })
 },
 //拖动
 sliderchange: function (e) {
 let data = e.currentTarget.dataset
 let controls = this.data.controls
 let control = controls.find(function (v) {
 return v.id == data.id
