微信小程序实现文字无限轮播效果

本文实例为大家分享了微信小程序实现文字无限轮播展示的具体代码，供大家参考，具体内容如下

.JS文件  onLoad中添加下列代码

var self = this;
var width = wx.getSystemInfoSync().screenWidth;
function carousel_num() {

var animation = wx.createAnimation({
transformOrigin: "50% 50%",
duration: 5000,
timingFunction: "linear",
delay: 0
})
self.animation = animation
animation.translate3d(-width, 0, 100).step()
console.log("第一动画开始");
self.setData({
animationData_notice: animation.export(),
})
setTimeout(function () {
var animation = wx.createAnimation({
transformOrigin: "50% 50%",
duration: 0,
timingFunction: "linear",
delay: 0
})
self.animation = animation
animation.translate3d(0, 0, 100).step()
console.log("第二动画开始");
self.setData({
animationData_notice: animation.export(),
})
setTimeout(function () {
carousel_num();
}, 50)
}, 5000)
}
setTimeout(function () {
carousel_num();
}, 100);

.WXML文件 添加如下：

<scroll-view class='scroll_notice'>
<view class='scroll_notice_item_bg' animation="{{animationData_notice}}">
<view class="scroll_notice_item_bg">
<image class='scroll_notice_item_image' src='图片链接'></image>
<view class='scroll_notice_item'>全国快递本月底将陆续停运，各位请注意补货时间！</view>
</view>
<view class="scroll_notice_item_bg">
<image class='scroll_notice_item_image' src='图片链接'></image>
<view class='scroll_notice_item'>全国快递本月底将陆续停运，各位请注意补货时间！</view>
</view>
</view>
</scroll-view>

.WXSS文件  添加如下：

.scroll_notice {
position: absolute;
left: 0px;
top: 0px;
width: 100%;
white-space: nowrap;
height: 65rpx;
background-color: #e6513e;
}

.scroll_notice_item_image {
position: absolute;
left: 0px;
top: 14rpx;
width: 49rpx;
height: 38rpx;
}

.scroll_notice_item {
margin-left: 61rpx;
margin-top: 14rpx;
height: 37rpx;
font-family: PingFangSC;
font-size: 26rpx;
font-weight: 500;
letter-spacing: 1rpx;
text-align: left;
color: #fff;
}

.scroll_notice_item_bg {
