动画函数
options的参数
from : 起始值 比如：0
to : 结束值 比如：100
totalms ：变化总时间 比如： 1000
duration : 每多少秒变化的次数 比如： 1
onmove ：开始移动的回调函数
onend ：移动结束的回调函数
let timer;
function createanimation(option) {
// 起始值、结束值、变化总时间
var {
from,
to,
totalms,
duration,
onmove,
onend
} = option;
totalms = totalms || 1000;
duration = duration || 10; // 每多少时间变化一次
var times = math.floor(totalms / duration); // 变化的次数
var dis = (to - from) / times; // 每次变化的量
var curtimes = 0;
// 每次变化的函数
var timer = setinterval(() => {
from += dis;
curtimes++;
// 变化完成，这里保证onmove 在 onend以前执行
if (curtimes >= times) {
from = to;
onmove && onmove(from);

}获取dom
我们点击跳转的时候,首先需要获取到当前点击 dom 的 status，如果当前的状态为 playing 直接 return,否则开始获取当前的 dom 信息，找到当前点击的 dom 和所要跳转到的 dom 所在位置，然后找到所要跳转的位置后，把当前点击的dom和所要去的dom传给开始的动画函数
handlegetdom(type) {
if (!type || type <= 0) return
let _this = this
wx.createselectorquery().select('.advertise-box').boundingclientrect()
.selectall('.grid-container .item').boundingclientrect().exec((ret) => {
const [poprect, enddoms] = ret;
const targetindex = enddoms.findindex((item) => item.id == type);
if (targetindex === -1) return;
const enddom = enddoms[targetindex];
_this.starttransition(poprect, enddom);
})
},开始动画过渡
根据获取 dom 和所要去的 dom 的位置,在拿到要结束 dom 之前先把 status 状态设置为 playing ，这样后我们就可以设置动画效果然后把对应的参数传给动画函数 createanimation 。
// 开始动画过渡
starttransition(poprect, enddom) {
const _this = this;
// 设置点击状态为playing
_this.setdata({
transitiondata: {
..._this.data.transitiondata,
statusbtn: 'playing'
}
});
const centerx = enddom.left
const centery = enddom.top
_this.setdata({
transitiondata: {
..._this.data.transitiondata,
animation: "shrinkandmovetoposition 2s forwards"
}
});
createanimation({
from: poprect.left,
to: centerx,
totalms: 1000,
onmove: (n) => {
_this.updatetransitiondata(enddom, centerx, centery);
},
onend: () => {
_this.endtransition(enddom);
}
});
},动画的更新函数
这个地方需要注意的是在支付宝中 left、top 不用需要加 px,width和height自行决定用不用除以2
// 更新动画过程中的数据
updatetransitiondata(enddom, centerx, centery) {
this.setdata({
transitiondata: {
...this.data.transitiondata,
width: `${enddom.width / 2}px`,
height: `${enddom.height / 2}px`,
left: `${centerx}px`,
top: `${centery}px`
}
});
},动画的结束函数
在动画结束的时候我们需要把 status 更改为 end , opacity 设置为 0，清除定时器就可以了
// 结束动画并处理跳转
endtransition(enddom) {
const _this = this;
wx.showtabbar();
_this.setdata({
transitiondata: {
..._this.data.transitiondata,
statusbtn: 'end',
opacity: 0
},
advertiseflag: false
});
clearinterval(timer);
const curritem = {
...enddom.dataset.item,
richtexttype: 2,
appletadvertisementid: enddom.dataset.item.type
}
_this.handlejumptypepage(curritem);
},动画所有相关的事件函数
