【今天吃什么】uniApp和微信小程序同款炫酷摇一摇来告诉你!

2023-02-18 16:32:26 时间

前言

本篇文章是用UniApp开发的,但是由于调用的API只是被UniApp封装好的微信API,所以整个功能是可以完全使用微信小程序原生开发的。

如果想用原生小程序开发,在调用uni.xxx类似的API方法时,只需要将 uni 替换成 wx 即可。

某些配置文件内容,会从uniapp和微信小程序两个维度去进行说明,方便不同框架的程序员来开发使用。

先来展示一下看看叭

自定义顶部栏

微信小程序是自带一个顶部标题栏的,需要手动配置才会隐藏。

uniapp 是在 page.json 文件中配置当前路由

{
    "path" : "pages/eat/eat",
    "style" :                                                                                    
    {
        "navigationBarTitleText": "吃点啥",
        "enablePullDownRefresh": false,
        "navigationStyle": "custom"
    }}
  • "navigationStyle": "custom"表示自定义当前页面顶部栏

微信小程序 则是直接在当前页面的json文件中配置

{
    "navigationStyle": "custom"}

画流星

  • 去掉了微信顶部栏之后,就可以直接做一个全屏的动画效果了,我这里做的是流星,大家也可以在我其他文章中找不同的动画效果替换上去。

画流动的波浪

  • 为了不让天上的星星太孤单,就得画一个波浪来陪伴!!skr!!!
<view class="tnwave waveAnimation">
        <view class="waveWrapperInner bgTop">
                <view class="wave waveTop" style="background-image: url('')"></view>
        </view>
        <view class="waveWrapperInner bgMiddle">
                <view class="wave waveMiddle" style="background-image: url('')"></view>
        </view>
        <view class="waveWrapperInner bgBottom">
                <view class="wave waveBottom" style="background-image: url('')"></view>
        </view></view>
  • 波浪的素材是三张图片,放在下面自取哦~~
  • bgTop 和 bgMiddle 中的image路径用的都是第一个哦,bgBottom 用的是第二个。
  • 用各种 P 图工具,可以用白色背景把 稀土掘金技术社区 签名给隐藏掉的哦~
.template-outset {        background-image: linear-gradient(to top, #4C3FAE 20%, #6E26BA 80%);        width: 100vw;        height: 100vh;
}@keyframes move_wave {        0% {                transform: translateX(0) translateZ(0) scaleY(1)
        }        50% {                transform: translateX(-25%) translateZ(0) scaleY(1)
        }        100% {                transform: translateX(-50%) translateZ(0) scaleY(1)
        }
}.tnwave {        overflow: hidden;        position: absolute;        left: 0;        right: 0;        bottom: 0;        top: 0;        margin: auto;

}.wave {        position: absolute;        left: 0;        width: 200%;        height: 100%;        background-repeat: repeat no-repeat;        background-position: 0 bottom;        transform-origin: center bottom;
}.bgTop {        opacity: 0.4;
}.waveTop {        background-size: 50% 45px;
}.waveAnimation .waveTop {        animation: move_wave 4s linear infinite;
}.bgMiddle {        opacity: 0.6;
}.waveMiddle {        background-size: 50% 40px;
}.waveAnimation .waveMiddle {        animation: move_wave 3.5s linear infinite;
}.bgBottom {        opacity: 0.95;
}.waveBottom {        background-size: 50% 35px;
}.waveAnimation .waveBottom {        animation: move_wave 2s linear infinite;
}

页面布局

为了让用户进来一眼就能知道是可以摇一摇的,我们需要加一个摇一摇的动图,放在最显眼的位置。

<view class="tn-flex tn-flex-direction-column tn-flex-col-center tn-flex-row-center">
        <view class="tn-flex tn-flex-col-center tn-flex-row-center">
                <view class="tn-shadow-blur" style="background-image:url('');width: 170rpx;height: 170rpx;background-size: cover;">
                </view>
        </view></view>
  • 摇一摇素材
.tn-flex {  display: -webkit-flex;  display: flex;
}.tn-flex-direction-column {  flex-direction: column;
}.tn-flex-col-center {  align-items: center;
}.tn-flex-row-center {  justify-content: center;
}.tn-shadow-blur {  position: relative;
}.tn-shadow-blur::before {  content: " ";  display: block;  background: inherit;  filter: blur(10rpx);  position: absolute;  width: 100%;  height: 100%;  top: 10rpx;  left: 10rpx;  z-index: -1;  opacity: 0.4;  transform-origin: 0 0;  border-radius: inherit;  transform: scale(1, 1);
}

然后加上自己喜欢的文字

<view class="tn-text-center tn-color-gray--disabled" style="padding: 60vh 0 0 0;">
        <view class="" style="font-size: 45rpx;">
                摇一摇        </view>
        <view class="tn-color-gray--disabled tn-text-df tn-padding-top">
                摇到什么吃什么        </view></view>
.tn-text-center {  text-align: center;
}.tn-color-gray--disabled {    color: #E6E6E6 !important;
}.tn-padding-top {    padding-top: 30rpx;
}

因为我做了一个领取外卖券的小程序,所以我在下面放了一个按钮,方便用户领券。

摇一摇,摇到什么吃什么

  • 进入页面就需要开始监听用户摇动手机的动作,所以需要把监听代码放到 onShow 生命周期中。
onShow() {    let _this = this
    let acc = true

    // 监听摇一摇
    uni.startAccelerometer({            success: function() {                    // 执行摇一摇
                    uni.onAccelerometerChange(function(res) {                            let page = getCurrentPages()                            let currentPage = page[page.length - 1]                            if(currentPage.route === 'pages/eat/eat'){                                    if (res.x > 1 || res.y > 1 || res.z > 1) {                                    // if (res.x > 3 || res.y > 3 || res.z > 3) {
                                            if(acc){
                                                    acc = false
                                                    uni.vibrateLong({                                                            success() {                                                                    // 随机摇一个值
                                                                    Array.prototype.random = function() {                                                                            let idx = Math.floor(Math.random() * this

  • 通过 uni.startAccelerometer 方法监听用户摇一摇的动作
  • 监听摇一摇的同时,为了避免跳出当前页之后还在监听,所以需要判断是否停留在当前页,所以需要用到 getCurrentPages方法获取当前页的路由。
  • 由于不知道用户是横着摇、竖着摇、斜着摇,所以需要判断 x、y、z三个方向的值。
    • 之前写的三个值都大于 3 ,经过某些 iPhone 用户测试,发现并不那么灵敏,所以改成了 1
  • 为了防止摇的时候一直出现随机值,在监听方法外部定义了一个 acc 的值,用于判断是否已经摇出来了。
  • 摇出随机值之后,需要给用户一个反馈信息,所以用了 uni.vibrateLong 方法来给一个长震动,让用户手机震动500ms

随机值可以自定义,想吃什么就添加什么,摇到什么就吃什么!
