本文实例为大家分享了小程序实现悬浮搜索框的具体代码，供大家参考，具体内容如下

悬浮搜索框是当数据界面不断滚动时，搜索框始终悬浮在最上方。来看一下效果图

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; 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 = "https://plete } }) }})
