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 }) }
