小程序实现上下移动切换位置

 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
 })
 }
