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

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
1 2 3 4 5 6 7 8 9 | handleGetDom(type) { if (!type || type { 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 。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | // 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
1 2 3 4 5 6 7 8 9 10 11 12 | // 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | // 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); }, |
