小程序開(kāi)發(fā)中實(shí)現(xiàn)地址頁(yè)面三級(jí)聯(lián)動(dòng)的方法

小編給大家分享一下小程序開(kāi)發(fā)中實(shí)現(xiàn)地址頁(yè)面三級(jí)聯(lián)動(dòng)的方法，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！

我遇到的問(wèn)題是

cdn.xitu.io/2018/5/29/163aa02a0f83cf57?imageView2/0/w/1280/h/960/format/webp/ignore-error/1">

后端給我的數(shù)據(jù)里面有每一個(gè)地址對(duì)應(yīng)的ID，比如北京：2 北京：50 東城區(qū)：500

處理這個(gè)數(shù)據(jù)的時(shí)候，我根據(jù)原來(lái)大神的代碼做了一些修改，

let val = e.detail.value,
            t = this.data.values,
            cityData = this.data.cityData,
            index = this.data.id,
            list = this.data.addrList;
            list[index].area = true;
            try {                if (val[0] != t[0]) { //當(dāng)val是選擇省份的時(shí)候
                const citys = [];
                const countys = [];
                    cityData[val[0]].child.map(item => citys.push({name:item.name,id:item.id}));
                    cityData[val[0]].child[0].child.map(item => countys.push({name:item.name,id:item.id}));
                    list[index].provinceName = this.data.provinces[val[0]].name;//省份
                    list[index].cityName = cityData[val[0]].child[0].name;//城市
                    list[index].districtName = cityData[val[0]].child[0].child[0].name;//地區(qū)
                    list[index].province = this.data.provinces[val[0]].id;//對(duì)應(yīng)的傳值ID
                    list[index].city = cityData[val[0]].child[0].id;//對(duì)應(yīng)的傳值ID
                    list[index].district = cityData[val[0]].child[0].child[0].id;//對(duì)應(yīng)的傳值ID
                this.setData({
                    citys: citys,
                    countys: countys,
                    values: val,
                    value: [val[0], 0, 0],
                    addrList: list
                })                    return;
                }                if (val[1] != t[1]) {//當(dāng)val是選擇城市的時(shí)候
                    const countys = [];
                    cityData[val[0]].child[val[1]].child.map(item => countys.push({name:item.name,id:item.id}));
                    list[index].cityName = this.data.citys[val[1]].name;// 選擇城市
                    list[index].city = this.data.citys[val[1]].id;//對(duì)應(yīng)的傳值ID
                    list[index].districtName = cityData[val[0]].child[val[1]].child[0].name;//選擇城市對(duì)應(yīng)的地區(qū)
                    list[index].district = cityData[val[0]].child[val[1]].child[0].id;//對(duì)應(yīng)的傳值ID
                    this.setData({
                        countys: countys,
                        values: val,
                        value: [val[0], val[1], 0],
                        addrList: list
                    })                    return;
                }                if (val[2] != t[2]) {//當(dāng)val是選擇地區(qū)的時(shí)候
                    list[index].districtName = this.data.countys[val[2]].name;//選擇地區(qū)
                    list[index].district = this.data.countys[val[2]].id;//對(duì)應(yīng)的傳值ID
                    this.setData({
                        county: this.data.countys[val[2]].name,
                        values: val,
                        addrList: list
                    })                    return;
                }    

            } catch(e) {
                // statements
                console.log(e);
            }
list里面是有 收貨人，電話，等等信息  但是我只操作改變數(shù)組里面地址改變的信息，

布局方面需要做一些修改的地方就是
