本示例展示了如何使用小程序实现悬浮搜索框的完整代码。代码提供参考，内容如下：
悬浮搜索框实现：- 当数据界面不断滚动时，搜索框始终悬浮在顶部。- UI代码如下：
- CSS样式代码：
css.search-container { position: fixed; top: 0; left: 0; width: 100%; background-color: #fff; z-index: 1000;}
.search-input { padding: 10px;}
.search-input input { width: 100%; height: 30px; border: 1px solid #ddd; border-radius: 15px; padding-left: 10px;}
- View代码：
javascriptPage({ data: { // 数据列表 dataList: [] }, onLoad: function () { // 加载数据 this.setData({ dataList: ['数据1', '数据2', '数据3', '数据4', '数据5'] }); }});
- CL代码（假设使用小程序自定义组件）：
javascriptComponent({ properties: { dataList: { type: Array, value: [] } }, data: { scrollTop: 0 }, methods: { handleScroll: function (e) { this.setData({ scrollTop: e.detail.scrollTop }); } }});
以上代码实现了一个悬浮在顶部的搜索框，当页面滚动时，搜索框位置保持不变。

UI代码
<view class="search-wrapper"> <view class="search-panel"> <view class="search-section"> <view class="search-button-wrapper"> <image class="search-button" src="/images/scan.png" bindtap="scan"></image> </view> <view class="search-input-wrapper "> <input bindinput="bindBarcodeInput" bindconfirm="query" bindfocus="bindBarcodeFocus" bindblur="bindBarcodeBlur" class="search-input" placeholder="扫描或者手动输入条码" value="{{barcode}}" confirm-type="search" /> </view> <view class="search-button-wrapper"> <image class="search-button" src="/images/search.png" bindtap="query"></image> </view> </view> </view> <view class="search-demo" hidden="{{hiddenDropdown}}"> <button size="mini" bindtap="setDemoData">示例</button> <button size="mini" bindtap="clear" style="margin-left:10px;">清空</button> </view> </view>
样式
.search-wrapper { position: fixed;/*悬停搜索框的关键样式*/ top: 0px; left: 0; width: 100%; z-index: 999; } .search-panel { background-color: #f50; } .search-section { padding: 5px 0px; display: flex; flex-direction: row; } .search-demo { padding: 5px; flex-direction: row; background-color: #eee; padding-left:42px; align-items: flex-start; } .search-input-wrapper { flex: 8; padding: 5px; background-color: #eee; border-radius: 3px; } .search-input { padding-top: 5px; } .search-clear { float: right; width: 32px; height: 32px; z-index: 998; } .search-button-wrapper { padding-left: 5px; padding-right: 5px; padding-top:5px; } .search-button { flex: 1; border: none !important; color: white !important; width: 32px; height: 32px; }
JS代码
//获取应用实例 var app = getApp() Page({ data: { barcode: "", hiddenLoading: true, hiddenData: true, hiddenDropdown: true, hiddenClear:true, demoData: 'XXXX', Product: {}, }, bindBarcodeInput: function (e) { this.setData({ barcode: e.detail.value }) }, bindBarcodeFocus: function (e) { this.setData({ hiddenDropdown: false, hiddenClear:false }) }, bindBarcodeBlur: function (e) { this.setData({ hiddenDropdown: true, hiddenClear:true }) }, scan: function (e) { var that = this; wx.scanCode({ success: function (res) { that.setData({ barcode: res.result }); that.query(e); }, fail: function () { that.setData({ barcode: "", hiddenData: true }); }, complete: function () { // complete } }) }, setDemoData: function (e) { this.setData({ barcode: this.data.demoData }); }, clear: function (e) { this.setData({ barcode: "", hiddenData: true }); }, query: function (e) { var url = "www.xxx.com/query";//查询数据的URL var that = this; if (that.data.barcode == undefined || that.data.barcode == null || that.data.barcode.length <= 0) { that.setData({ hiddenData: true }); wx.showToast({ title: '请输入条码', image: '/images/fail.png', duration: 2000 }); return; } wx.request({ url: url, data: { barcode: that.data.barcode }, method: 'GET', success: function (res) { var result = res.data; if (result.Status != 0) { that.setData({ hiddenData: true }); wx.showToast({ title: result.Message, image: '/images/fail.png', duration: 2000 }) return; } that.setData({ Product: result.Data, hiddenData: false }); wx.showToast({ title: "获取数据成功", image: '/images/ok.png', duration: 2000 }) }, fail: function (e) { var toastText = '获取数据失败' + JSON.stringify(e); that.setData({ hiddenLoading: !that.data.hiddenLoading, hiddenData: true }); wx.showToast({ title: toastText, icon: '', duration: 2000 }) }, complete: function () { // complete } }) } })
