本文实例为大家分享了微信小程序开发animation心跳动画,供大家参考,具体内容如下
1、微信小程序开发animation心跳动画
wxml文件中:
js文件中:
页面渲染完成
onReady: function () {
var circleCount = 0;
// 心跳的外框动画
this.animationMiddleHeaderItem = wx.createAnimation({
duration:1000,// 以毫秒为单位
/**
* http://cubic-bezier.com/#0,.58,1
* linear 动画一直较为均匀
* ease 从匀速到加速在到匀速
* ease-in 缓慢到匀速
* ease-in-out 从缓慢到匀速再到缓慢
*
* http://www.tuicool.com/articles/neqMVr
* step-start 动画一开始就跳到 100% 直到动画持续时间结束 一闪而过
* step-end 保持 0% 的样式直到动画持续时间结束 一闪而过
*/
timingFunction: 'linear',delay: 100,transformOrigin: '50% 50%',success: function (res) {
}
});
setInterval(function() {
if (circleCount % 2 == 0) {
this.animationMiddleHeaderItem.scale(1.15).step();
} else {
this.animationMiddleHeaderItem.scale(1.0).step();
}
this.setData({
animationMiddleHeaderItem: this.animationMiddleHeaderItem.export()
});
circleCount++;
if (circleCount == 1000) {
circleCount = 0;
}
}.bind(this),1000);
},
2、微信显示倒计时
wxml文件中:
js文件中:
函数
bindViewTap: function() {
wx.navigateTo( {
url: '../logs/logs'
})
},onLoad: function() {
this.setData( {
windowHeight: wx.getStorageSync( 'windowHeight' )
});
},// 页面渲染完成后 调用
onReady: function () {
var totalSecond = 1505540080 - Date.parse(new Date())/1000;
var interval = setInterval(function () {
// 秒数
var second = totalSecond;
// 天数位
var day = Math.floor(second / 3600 / 24);
var dayStr = day.toString();
if (dayStr.length == 1) dayStr = '0' + dayStr;
// 小时位
var hr = Math.floor((second - day * 3600 * 24) / 3600);
var hrStr = hr.toString();
if (hrStr.length == 1) hrStr = '0' + hrStr;
// 分钟位
var min = Math.floor((second - day * 3600 *24 - hr * 3600) / 60);
var minStr = min.toString();
if (minStr.length == 1) minStr = '0' + minStr;
// 秒位
var sec = second - day * 3600 * 24 - hr * 3600 - min*60;
var secStr = sec.toString();
if (secStr.length == 1) secStr = '0' + secStr;
this.setData({
countDownDay: dayStr,countDownHour: hrStr,countDownMinute: minStr,countDownSecond: secStr,});
totalSecond--;
if (totalSecond < 0) {
clearInterval(interval);
wx.showToast({
title: '活动已结束',});
this.setData({
countDownDay: '00',countDownHour: '00',countDownMinute: '00',countDownSecond: '00',});
}
}.bind(this),//cell事件处理函数
bindCellViewTap: function (e) {
var id = e.currentTarget.dataset.id;
wx.navigateTo({
url: '../babyDetail/babyDetail?id=' + id
});
}
})
