Dieser Artikel stellt hauptsächlich die relevanten Methoden zur Auswahl von Städten basierend auf Buchstaben im WeChat-Applet vor. Er hat einen gewissen Referenzwert.

Entwickeln Sie heute ein kleines Programm, das die Region betrifft Nachdem ich einige Versionen im Internet gelesen habe, habe ich das Gefühl, dass der Text unvollständig ist. Heute werde ich die Antworten im Internet zusammenfassen und nach meinen eigenen Bedürfnissen neu ordnen. Ich hoffe, es hilft allen. Werfen wir zunächst einen Blick auf die Screenshots:

Projekt-Screenshots

Sortieren wir den Code unten.

1. Erstellen Sie die Datei index.wxml

Erstellen Sie im Ordner „pages->index“ eine neue Datei index.wxml mit dem folgenden Code:

 class="title">
  class="title_list" value="{{cityName}}" placeholder="城市名称" />
 确认
  scroll-y="true" style="height: {{winHeight}}px;" scroll-into-view="{{scrollTopId}}" class="city_list">
   wx:for="{{city}}" wx:for-index="idx" wx:for-item="cityName">
    id="{{idx}}" class="list_tit">{{idx}}
    wx:for="{{cityName}}">
     class="list_con" data-city="{{item.name}}" bindtap="bindCity">{{item.name}}
   
  
 class="scroll_list" 
   bindtouchstart="chStart"
   bindtouchend="chEnd"
   catchtouchmove="chMove"
   style="background: rgba(0,0,0,{{trans}});"
   >
  wx:for="{{city}}" wx:for-index="idx" wx:for-item="cityName">
    wx:if="{{idx != '热门城市'}}">
    id="{{idx}}" class="scroll_list_chi" style="line-height:{{lineHeight}}px ; height:{{lineHeight}}px ;font-size:{{lineHeight/1.7}}px;" bindtouchstart="getWords" bindtouchend="setWords">{{idx}}
   
  
 hidden="{{hidden}}" class="showwords">
 {{showwords}}

2. Erstellen Sie das entsprechende CSS

Erstellen Sie im Ordner „pages->index“ eine neue index.wxss-Datei mit dem folgenden Code:

/**index.wxss**/
.title {
  position: relative;
  padding: 10px 0;
}
.title_list {
  display: inline-block;
  padding: 0 15px;
  height: 20px;
  line-height: 20px;
  font-size: 16px;
}
.title button {
  width: 50px;
  height: 30px;
  font-size: 16px;
  padding: 0;
  line-height: 30px;
  margin: auto;
  position: absolute;
  top: 0;
  bottom:0;
  right: 10px;
  background: none;
}
.title button::after {
  border: none;
}
.title_list:nth-child(1) {
  border-right:1px #ccc solid;
}
/*城市列表*/
.city_list {
  position: relative;
}
/*城市选择头部*/
.list_tit {
  display: block;
  line-height: 40px;
  height: 40px;
  padding-left: 15px;
  font-size: 16ppx;
  background: #f5f5f5;
  color: #666;
}
.list_con {
  height: 40px;
  /*border-top: 1px #f5f5f5 solid ;*/
  line-height: 40px;
  font-size: 16px;
  padding-left: 15px;
}
.list_con::before {
  content: " ";
  height: 1px;
  border-top: 1px #f5f5f5 solid;
  position: absolute;
  width: 100%;
}
.list_con::before:nth-child(1) {
  border: none;
}
/*城市选择 右边*/
.scroll_list {
  background: rgba(0,0,0,0);
  position: absolute;
  height: calc(100% - 100px);
  width: 25px;
  top: 90px;
  right: 10px;
}
.scroll_list_chi {
  /*border: 1px blue solid;*/
  text-align: center;
  font-size: 12px;
}
/*显示框*/
.showwords {
  width: 80px;
  height: 80px;
  background: rgba(0,0,0,.3);
  border-radius:50%;
  line-height: 80px;
  text-align: center;
  font-size:10vw;
  margin: auto;
  position: absolute;
  top: 0;left: 0;bottom: 0;right: 0;
  z-index: 999;  
}

3. Erstellen Sie eine JS-Datei

Erstellen Sie im Ordner „pages->index“ eine neue index.js-Datei mit dem folgenden Code:

//先引用城市数据文件
var city = require('../../utils/city.js')
var lineHeight = 0;
var endWords = "";
var isNum;
Page({
 data: {
  "hidden": true,
  cityName:"", //获取选中的城市名
 },
 onLoad: function (options) {
  // 生命周期函数--监听页面加载
 },
 onReady: function () {
  // 生命周期函数--监听页面初次渲染完成
  var cityChild = city.City[0];
  var that = this;
  wx.getSystemInfo({
   success: function (res) {
    lineHeight = (res.windowHeight - 100) / 22;
    console.log(res.windowHeight - 100)
    that.setData({
     city: cityChild,
     winHeight: res.windowHeight - 40,
     lineHeight: lineHeight
    })
   }
  })
 },
 onShow: function () {
  // 生命周期函数--监听页面显示
 },
 onHide: function () {
  // 生命周期函数--监听页面隐藏
 },
 onUnload: function () {
  // 生命周期函数--监听页面卸载
 },
 //触发全部开始选择
 chStart: function () {
  this.setData({
   trans: ".3",
   hidden: false
  })
 },
 //触发结束选择
 chEnd: function () {
  this.setData({
   trans: "0",
   hidden: true,
   scrollTopId: this.endWords
  })
 },
 //获取文字信息
 getWords: function (e) {
  var id = e.target.id;
  this.endWords = id;
  isNum = id;
  this.setData({
   showwords: this.endWords
  })
 },
 //设置文字信息
 setWords: function (e) {
  var id = e.target.id;
  this.setData({
   scrollTopId: id
  })
 },
 // 滑动选择城市
 chMove: function (e) {
  var y = e.touches[0].clientY;
  var offsettop = e.currentTarget.offsetTop;
  var height = 0;
  var that = this;
  ;
  var cityarr = ["A", "B", "C", "D", "E", "F", "G", "H", "J", "K", "L", "M", "N", "P", "Q", "R", "S", "T", "W", "X", "Y", "Z"]
  // 获取y轴最大值
  wx.getSystemInfo({
   success: function (res) {
    height = res.windowHeight - 10;
   }
  });
  //判断选择区域,只有在选择区才会生效
  if (y > offsettop && y < height) {
   // console.log((y-offsettop)/lineHeight)
   var num = parseInt((y - offsettop) / lineHeight);
   endWords = cityarr[num];
   // 这里 把endWords 绑定到this 上,是为了手指离开事件获取值
   that.endWords = endWords;
  };
  //去除重复,为了防止每次移动都赋值 ,这里限制值有变化后才会有赋值操作,
  //DOTO 这里暂时还有问题,还是比较卡,待优化
  if (isNum != num) {
   // console.log(isNum);
   isNum = num;
   that.setData({
    showwords: that.endWords
   })
  }
 },
 //选择城市,并让选中的值显示在文本框里
 bindCity: function(e) {
  console.log(e);
  var cityName = e.currentTarget.dataset.city;
  this.setData({ cityName: cityName })
 }
})

4. City-Datei erstellen

Erstellen Sie die Datei city.js im Ordner utils. Der spezifische Code lautet wie folgt:

var city = {
 "City": [
  {
   "热门城市": [
    {
     "name": "北京",
     "key": "热门"
    },
    {
     "name": "上海",
     "key": "热门"
    },
    {

     "key": "热门"
    },
    {
     "name": "深圳",
     "key": "热门"
    },
    {
