前言
继续改昨天的界面，我们在上周写的都是静态页面，这周开始给静态界面加上javascript，可以让其互相跳转，再加上一些功能。
Find.html
// 歌曲列表
let songs = [

let narrateEL = document.querySelector('.story-box')

// 2. 生成每一个歌曲元素
var divel = document.createElement('div')
// 3. 给歌曲元素添加类名
divel.className = 'item'
// 4. 设置歌曲元素的内容
divel.innerHTML = `

}
var goToSong = function (sid) {

}
var searchStr=document.querySelector('#searchStr')
var goToSearch = function () {
// console.log(searchStr.value)
location.href = './search.html?searchStr=' + searchStr.value
}
我们增加了音乐播放的功能，在播放的时候，让其跳转到音乐播放界面。
song-info.html
// 获取到地址栏中的参数 ?sid=1
var url = location.search
// slice() 去掉字符串前面的问号 sid=1
url = url.slice(1)
console.log(url.split('=')) // ['sid', '1']
var sid = url.split('=')[1]
console.log(sid)
// 歌曲列表
let songs = [{

]
// 根据sid获取歌曲信息
var song = songs.find(function (item) {
return item.sid == sid
})
console.log(song)
var coverImg = document.querySelector('.cover')
console.log(coverImg)
coverImg.src = song.cover
var audioEl = document.querySelector('audio')
audioEl.src = song.url
var info = document.querySelectorAll('.info span')
console.log(info[0])
info[0].innerHTML = song.title
info[1].innerHTML = song.singer
var goBack = function () {
history.back()
}
并且这个播放界面可以用返回按钮，返回到发现页面。
search.html
我们还做了搜索的界面，假如我们在发现页搜索的话，可以显示出相应结果。
// 1. 获取要搜索的内容
// ?searchStr=你
var url = location.search
url = url.slice(1)
var params = new URLSearchParams(url)
console.log(params.get('searchStr'))
var searchStr = params.get('searchStr')
// 歌曲列表

]
// 2. 获取搜索结果
var songList = songs.filter(function (item) {
// includes方法 判断是否包含指定字符串
return item.title.includes(searchStr)
})
console.log(songList)
// 3. 生成html元素
var songListel = document.querySelector('.box')
for (var song of songList) {
console.log(song)
var divel = document.createElement('div')
divel.className = 'item'
divel.innerHTML = `

}
var goBack = function () {

}
var goToSong = function (sid) {

}
console.log(sid)
搜索“你”会出现如下结果，并且也可以返回。
sheet.html
// 1. 获取歌单的id
// ?sid=10
var url = location.search

var params = new URLSearchParams(url)
console.log(params.get('sid'))

}
]
// 2. 根据id获取歌单信息
var sheet = songSheets.find(function (item) {
return item.sid == sid
})
console.log(sheet)
// 3. 显示歌单信息
var infoImg = document.querySelector('.info .left img')
infoImg.src = sheet.pic
var infoTitle = document.querySelector('.info .right .title')
var infoAuthor = document.querySelector('.info .right .avator span')
infoTitle.innerHTML = sheet.title
infoAuthor.innerHTML = sheet.comment
把主页的歌单也完善一下，就可以跳转了。
歌单界面都是不一样的，歌曲也要相应的做出更改。
