 本文实例为大家分享了小程序实现上下移动切换位置的具体代码，供大家参考，具体内容如下

<view wx:for="{{companyData}}" wx:key="{{item.id}}" class="overHiden">
 <view class="floarLeft">{{item.name}}</view>
 <view class="floarRight" wx:if="{{index != 0}}" data-index="{{index}}" bindtap="topClick">
 <image src="../../images/32.png" class="rightmenuImg"></image>
 </view>
 <view class="floarRight" wx:if="{{index != companyData.length-1}}" data-index="{{index}}" bindtap="bottomClick">
 <image src="../../images/33.png" class="rightmenuImg"></image>
 </view>
</view>

data{
 companyData:[
 {
 id:0,
 name:'产品1'
 },
 {
 id:1,
 name:'产品2'
 },
 {
 id:2,
 name:'产品3'
 },
 {
 id:3,
 name:'产品4'
 },
 {
 id:4,
 name:'产品5'
 }
 ]
}

//位置向上移动
topClick: function(e) {
 var that = this
 var index = e.currentTarget.dataset.index
 var one = that.data.companyData[index]
 var two = that.data.companyData[index - 1]
 var index2 = index - 1
 var data1 = "companyData[" + index + "]"
 var data2 = "companyData[" + index2 + "]"
 that.setData({
 [data1]: two,
 [data2]: one
 })
 },
 // 位置向下移动
 bottomClick: function(e) {
 var that = this
 var index = e.currentTarget.dataset.index
 var one = that.data.companyData[index]
 var two = that.data.companyData[index + 1]
 var index2 = index + 1
 var data1 = "companyData[" + index + "]"
 var data2 = "companyData[" + index2 + "]"
 that.setData({
 [data1]: two,
 [data2]: one
 })
 }
