代码很简单.
var city = require('../../utils/city.js');
var app = getApp()
Page({
data: {
searchLetter: [],
showLetter: "",
winHeight: 0,
// tHeight: 0,
// bHeight: 0,
cityList: [],
isShowLetter: false,
scrollTop: 0,//置顶高度
scrollTopId: '',//置顶id
city: "上海市",
hotcityList: [{ cityCode: 110000, city: '北京市' }, { cityCode: 310000, city: '上海市' }, { cityCode: 440100, city: '广州市' }, { cityCode: 440300, city: '深圳市' }, { cityCode: 330100, city: '杭州市' }, { cityCode: 320100, city: '南京市' }, { cityCode: 420100, city: '武汉市' }, { cityCode: 410100, city: '郑州市' }, { cityCode: 120000, city: '天津市' }, { cityCode: 610100, city: '西安市' }, { cityCode: 510100, city: '成都市' }, { cityCode: 500000, city: '重庆市' }]
},
onLoad: function () {
// 生命周期函数--监听页面加载
var searchLetter = city.searchLetter;
var cityList = city.cityList();
var sysInfo = wx.getSystemInfoSync();
var winHeight = sysInfo.windowHeight;
var itemH = winHeight / searchLetter.length;
var tempObj = [];
for (var i = 0; i < searchLetter.length; i++) {
var temp = {};
temp.name = searchLetter[i];
temp.tHeight = i * itemH;
temp.bHeight = (i + 1) * itemH;
tempObj.push(temp)
}
this.setData({
winHeight: winHeight,
itemH: itemH,
searchLetter: tempObj,
cityList: cityList
})
},
onReady: function () {
// 生命周期函数--监听页面初次渲染完成
},
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
},
onPullDownRefresh: function () {
// 页面相关事件处理函数--监听用户下拉动作
},
onReachBottom: function () {
// 页面上拉触底事件的处理函数
},
clickLetter: function (e) {
console.log(e.currentTarget.dataset.letter)
var showLetter = e.currentTarget.dataset.letter;
this.setData({
showLetter: showLetter,
isShowLetter: true,
scrollTopId: showLetter,
})
var that = this;
setTimeout(function () {
that.setData({
isShowLetter: false
})
}, 1000)
},
//选择城市
bindCity: function (e) {
console.log("bindCity")
this.setData({ city: e.currentTarget.dataset.city })
},
//选择热门城市
bindHotCity: function (e) {
console.log("bindHotCity")
this.setData({
city: e.currentTarget.dataset.city
})
},
//点击热门城市回到顶部
hotCity: function () {
this.setData({
scrollTop: 0,
})
}
})以上就是本文的全部内容，希望对大家的学习有所帮助，更多相关内容请关注PHP中文网！
