本文介紹了小程式頭部吸頂的實現程式碼示例，分享給大家，也給自己留個筆記

demo 地址: https://github.com/iotjin/Jh_weapp

效果圖：

吸頂主要是 position: sticky;

.header {
 background: rgb(230,230,230);
 height: 25px;
 line-height: 25px;
 padding-left: 30rpx;
 font-size: 13px;
 align-items: center;
 position: sticky;
 top: 0;
}

js 程式碼：

Page({
 data: {
  dataArr: [{
    "AB_MonthDay": "30/06","AB_ZhiChu": "1111","AB_ShouRu": "2222","AB_Bill": [{
     "AB_LeiBie": "吃飯1","AB_Money": "11","AB_Remark": "備註","AB_Date": "2011-11-11 15:38:16","AB_FenLei": "支出",},{
     "AB_LeiBie": "吃飯1","AB_Money": "22","AB_Remark": "備註2",{
     "AB_LeiBie": "紅包1","AB_Money": "33","AB_Remark": "備註33","AB_FenLei": "收入",]
   },{
    "AB_MonthDay": "29/06","AB_Bill": [{
     "AB_LeiBie": "吃飯2","AB_Remark": "",}]
   },{
    "AB_MonthDay": "28/06","AB_Bill": [{
     "AB_LeiBie": "吃飯3",{
    "AB_MonthDay": "27/06","AB_Bill": [{
     "AB_LeiBie": "吃飯4","AB_Money": "44",{
    "AB_MonthDay": "26/06",{
    "AB_MonthDay": "25/06",{
    "AB_MonthDay": "24/06",{
    "AB_MonthDay": "23/06",{
    "AB_MonthDay": "22/06",{
    "AB_MonthDay": "21/06",{
    "AB_MonthDay": "20/06",{
    "AB_MonthDay": "19/06",]

 },onShow: function () {
 },onPageScroll: function (res) {
  console.log(res.scrollTop);
 }

})

wxml 程式碼：

<view class="main-bg">
	<view wx:for="{{dataArr}}" wx:key="index" class="section">
		<view class="header"> {{item.AB_MonthDay}}</view>
		<view wx:for="{{item.AB_Bill}}" wx:key="index" class="cell">
    <view class="row1">
     <view wx:if="{{item.AB_Remark}}" class="leibie">{{item.AB_LeiBie}} · {{item.AB_Remark}}</view>
     <view wx:else="{{!item.AB_Remark}}" class="leibie">{{item.AB_LeiBie}}</view>
     <view class='{{item.AB_FenLei=="收入"?"money2":"money"}}'>{{item.AB_Money}}</view>
    </view>
		</view>
	</view>
</view>

wxss 程式碼：

.header {
 background: rgb(230,230);
 height: 25px;
 line-height: 25px;
 padding-left: 30rpx;
 font-size: 13px;
 align-items: center;
 position: sticky;
 top: 0;
}

.cell {
 background: white;
 height: 44px;
 align-items: center;
 line-height: 44px;
 border-bottom: 1px solid rgb(230,230);
}

.row1 {
 margin-left: 30rpx;
 display: flex;
 justify-content: space-between;
}
.leibie {
 width: 70%;
 font-size: 30rpx;
 color: black;
 text-overflow: ellipsis;
 white-space: nowrap;
 overflow: hidden;
}
.money {
 font-size: 32rpx;
 color: black;
 font-weight: bold;
 margin-right: 30rpx;
}

.money2 {
 font-size: 32rpx;
 color: #38BC9D;
 font-weight: bold;
 margin-right: 30rpx;
}
