微信小程序音樂播放器,音樂播放器檢索頁制作(中)
這部分也是列表樣式,每一項由前面的時鐘圖標,中間的文字以及最后表示刪除的“X”組成,最下方為清空整個列表的選項。
- <view class="search-hi" wx:if="{{showSearchPanel == 2}}">
- <block wx:if="{{historySearchs.length > 0}}">
- <view class="search-hi-item" wx:for="{{historySearchs}}" wx:key="unique">
- <view class="hi-icon"></view>
- <text class="hi-text" data-key="{{item}}" bindtap="historysearchTap">{{item}}</text>
- <view class="hi-close" data-index="{{index}}" bindtap="delHistoryItem"></view>
- </view>
- <view class="clear-serach" bindtap="clearHistorySearchs">清除搜索記錄</view>
- </block>
- </view>
這一部分只有當showSearchPanel=2才顯示。
具體的內(nèi)容,我們首先要判斷是否有歷史數(shù)據(jù)。使用historySearchs存儲所以歷史記錄,只有當其長度大于0時,才渲染這一部分。
block里的內(nèi)容就如我們所要的一致,然后我們?yōu)槲淖?,結(jié)尾的“X”標志,和最后的“清除搜索記錄”添加點擊事件。
格式文件為:
- .search-hi-item {
- height:88rpx;
- line-height:88rpx;
- border-bottom:2rpx solid #ededed;
- }
- .hi-icon {
- position:absolute;
- left:20rpx;
- display:inline-block;
- width:88rpx;
- height:88rpx;
- background:url('../../resources/images/clock_ic.png') no-repeat center center;
- background-size:40rpx;
- }
- .hi-text {
- position:absolute;
- left:108rpx;
- right:108rpx;
- display:block;
- white-space:nowrap;
- text-overflow:ellipsis;
- overflow:hidden;
- font-size:32rpx;
- }
- .hi-close {
- width:88rpx;
- height:88rpx;
- position:absolute;
- right:20rpx;
- background:url('../../resources/images/cancel.png') no-repeat center center;
- }
- .clear-serach {
- font-size:24rpx;
- text-align:center;
- color:#47c88a;
- line-height:88rpx;
- }
background里加載了分別加載了兩個本地圖片并為其設(shè)置了不平鋪與居中的屬性。
很顯然,在我們每次點擊確定按鈕后,輸入框內(nèi)的值除了發(fā)送到服務(wù)器請求搜索結(jié)果,還要添加到historySearchs里。
所以我們先寫搜索結(jié)果列表,然后一起處理確定按鈕的點擊事件。
首先是網(wǎng)絡(luò)請求的函數(shù):
- function getSearchMusic(word,callback){ //word為傳入的關(guān)鍵字,callback為回調(diào)函數(shù)
- var data = {
- g_tk: 5381,
- uin: 0,
- format: 'json',
- inCharset: 'utf-8',
- outCharset: 'utf-8',
- notice: 0,
- platform: 'h5',
- needNewCode: 1,
- w: word,
- zhidaqu: 1,
- catZhida: 1,
- t: 0,
- flag: 1,
- ie: 'utf-8',
- sem: 1,
- aggr: 0,
- perpage: 20,
- n: 20,
- p: 1,
- remoteplace: 'txt.mqq.all',
- _: Date.now()
- };
- wx.request({
- url: 'http://c.y.qq.com/soso/fcgi-bin/search_for_qq_cp',
- data: data,
- header: {
- 'Content-Type': 'application/json'
- },
- success: function (res) {
- if (res.statusCode == 200) {
- callback(res.data);
- } else {
- }
- }
- });
- }
- ...
- module.exports = {
- ...
- getSearchMusic:getSearchMusic
- }
返回的JSON數(shù)據(jù)為:

有了數(shù)據(jù)之后,我們需要在列表里顯示的內(nèi)容為歌曲名稱(songname)與歌手名稱(singer.name)。
