本文实例为大家分享了微信小程序实现手指拖动选项排序的具体代码，供大家参考，具体内容如下
效果：
wxml：
手指移动选项排序 {{index+1}} {{item.member.nickname}}
js：
let app = getApp() app.unitgameinfo = {"members":[{"member":{"nickname":"小程序照片合成","job":"ckext"},},{"member":{"nickname":"高球丸子"},},{"member":{"nickname":"DRobertdsf","job":"黄金"},},{"member":{"nickname":"erer","job":"ckext"},},{"member":{"nickname":"just do it","job":"黄金"},},{"member":{"nickname":"888"},}],}; Page({ data: { }, onLoad: function (options) { var info = app.unitgameinfo,list; list = info.members; this.setData({options,info,list}); this.getwxmlcode("#movebox",(resp)=>{ this.setData({movebox:resp}) setTimeout(()=>{this.getwxmlcode("#movelist0",(res)=>{ this.setData({movelist0:res}) var jiange = res.top-resp.top; var yiban = res.bottom - res.top + jiange; this.setData({ itemheight:res.bottom - res.top, jiange:yiban, //两条中间到另一条的距离 jianqu:resp.top-(res.bottom - res.top)/2, //位置要减去距离 }) })},300) }) }, getwxmlcode(str,cal){ const query1 = wx.createSelectorQuery() query1.select(str).boundingClientRect() query1.selectViewport().scrollOffset() query1.exec((res) => { if(cal) cal(res[0]) }) }, listitemmove(e){ // console.log(e) if(e.type=="touchmove"){ var movetop = e.touches[0].pageY-this.data.itemheight; var moveoutindex = parseInt((movetop-this.data.jianqu)/this.data.jiange); if(e.currentTarget.dataset.index<=moveoutindex) moveoutindex++; this.moveoutindex = moveoutindex; this.setData({nowmoveindex:e.currentTarget.dataset.index,movetop,moveoutindex}) }else{ let index = e.currentTarget.dataset.index,score = this.data.list; let data = {...score[index]}; score.splice(index,1); if(index<=this.moveoutindex-1) this.moveoutindex--; score.splice(this.moveoutindex,0,data); this.setData({list:score,moveoutindex:-1,nowmoveindex:-1}); } }, onShow: function(){ }, lastsubmit(){ console.log(this.data.list) }, })
wxss：
page{background-color: #fff;font-size:30rpx;text-align: center;color: #2952a5;} .tijiao{ color: #fff;font-size: 30rpx;line-height: 2.8; margin: 20rpx auto 20rpx;width:80vw;position: fixed;bottom: 50rpx;left: 10vw; background-color: #2952a5;border-radius:50rpx; } .dileiitemlist{justify-content: center;padding-top:30rpx;flex-wrap: wrap;} .dileititle{font-size: 32rpx;line-height: 100rpx;} .ranknum{width:60rpx;height: 60rpx;line-height: 60rpx;text-align: center;border-radius:50%;border:1rpx solid #2952a5;margin-right:30rpx;} .changemovenow{width:100%;height:60px!important;} .flex1{display:flex;align-items:center;}
