packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    let renderChild = children.slice()
+    if (props.circular && totalElements.value > 1) {
+      if (totalElements.value === 2) {
+        renderChild = renderChild.concat(children).concat(children)


添加节点需要cloneElement

hiyuki · 2024-11-21T08:22:56Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        renderChild = renderChild.concat(children).concat(children)
+      } else {
+        // 最前加两个
+        renderChild.unshift(children[totalElements.value - 1])


前面不需要加元素

hiyuki · 2024-11-21T08:24:27Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  ], { layoutRef: layoutRef })
+
+  function onWrapperLayout (e: LayoutChangeEvent) {
+    nodeRef.current?.measure((x: number, y: number, width: number, height: number, offsetLeft: number, offsetTop: number) => {


layout里面可以直接获取高宽，不需要measure

hiyuki · 2024-11-21T08:24:35Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+
+  function onWrapperLayout (e: LayoutChangeEvent) {
+    nodeRef.current?.measure((x: number, y: number, width: number, height: number, offsetLeft: number, offsetTop: number) => {
+      layoutRef.current = { x, y, width, height, offsetLeft, offsetTop }


hiyuki · 2024-11-21T08:29:49Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        }
+        const attr = dir.value === 'x' ? 'width' : 'height'
+        changeState[attr] = changeState[attr] - previousMargin - nextMargin
+        if (dir.value === 'x') {


这里不应该都去设置么

hiyuki · 2024-11-21T08:31:38Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    if (totalElements.value <= 1) return null
+    const dots: Array<ReactNode> = []
+    for (let i = 0; i < totalElements.value; i++) {
+      const dotStyle = useAnimatedStyle(() => {


不应该在for中使用hooks，假如elements数量更新了就炸了

hiyuki · 2024-11-21T08:40:05Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  }
+
+  function handlerInterval (loopv: boolean, oldLoop: boolean | null) {
+    clearInterval(intervalId.current)


为啥有一个timeout有一个interval?

hiyuki · 2024-11-21T08:41:07Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+          intervalId.current = setInterval(() => {
+            // canLoop变化比较快的情况下
+            if (canLoop.value) {
+              createAutoPlay()


这个东西为啥要声明为worklet？看上去是个纯js函数

hiyuki · 2024-11-21T08:42:22Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    if (!isInit && props.bindchange) {
+      runOnJS(handleSwiperChange)(newIndex)
+    }
+  }, [targetIndex.value])


这里不需要写deps把

hiyuki · 2024-11-21T08:43:18Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    }
+  }, [targetIndex.value])
+
+  useAnimatedReaction(() => canLoop.value, (loopv, oldLoop) => {


canLoop是干啥的

hiyuki · 2024-12-19T10:01:28Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+          extraStyle
+        ]}
+        key={ 'page' + index}>
+        <SwiperContext.Provider value={contextValue}>


顶层包一个就行了

hiyuki · 2024-12-19T10:01:53Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        offset,
+        stepValue: typeof stepValue === 'number' ? stepValue : 0
+      }
+      return (<Animated.View


不做动画不需要animated.view

hiyuki · 2024-12-19T10:03:11Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  }
+
+  function renderItems () {
+    const pageStyle = { width: widthState, height: heightState }


确定这块的必要性是啥

hiyuki · 2024-12-23T05:44:23Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  const touchfinish = useSharedValue(false)
+  // 用户是否触发了move事件,起点在onStart, 触发move事件才会执行onEnd, 1. 移动一定会触发onStart, onTouchesMove, onEnd 2. 点击未进行操作, 会触发onTouchsUp
+  const isTriggerStart = useSharedValue(false)
+  // 记录上一次的点击时的绝对定位坐标


这个不是点击，是上一帧

hiyuki · 2024-12-23T05:45:33Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  useNodesRef<View, SwiperProps>(props, ref, nodeRef, {})
+
+  // 默认取水平方向的width
+  const { width } = Dimensions.get('window')


这个有啥意义

hiyuki · 2024-12-23T05:50:34Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+      dots.push(<View style={[dotCommonStyle, { backgroundColor: unActionColor }]} key={i}></View>)
+    }
+    return (
+      <View pointerEvents="none" style = {[styles['pagination_' + dir.value]]}>


无意义的数组包裹

hiyuki · 2024-12-23T05:56:23Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        nextMargin && dir.value === 'y' && (extraStyle.marginBottom = nextMargin)
+      }
+      const newChild = React.cloneElement(child, { itemIndex: index, scale: props.scale })
+      return (<Animated.View style={[style.itemWrap, itemAnimatedStyles, extraStyle]} key={ 'page' + index}>{newChild}</Animated.View>)


把这个animatedStyle作为props传递到swiper-item中应用就可以了，没必要再包一层view

hiyuki · 2024-12-23T05:56:54Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+
+  function renderItems () {
+    const itemAnimatedStyles = useAnimatedStyle(() => {
+      const pageStyle: Object = dir.value === 'x' ? { width: step.value, height: '100%' } : { width: '100%', height: step.value }


无意义的变量定义

hiyuki · 2024-12-23T10:37:11Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+      }
+      const newChild = React.cloneElement(child, {
+        itemIndex: index,
+        scale: props.scale,


scale走context传递

hiyuki · 2024-12-23T10:38:34Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    }
+    const arrChilds = renderChild.map((child, index) => {
+      const extraStyle = {} as { [key: string]: any }
+      if (index === 0) {


circular判断

hiyuki · 2024-12-23T10:57:34Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        duration: easeDuration,
+        easing: easeMap[easeingFunc]
+      }, () => {
+        offset.value = targetOffset


没必要加的逻辑

hiyuki · 2024-12-23T11:05:38Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    }
+    const targetOffset = getInitOffset()
+    if (props.autoplay) {
+      pauseLoop()


pause的意义是啥

hiyuki · 2024-12-23T11:06:20Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    const targetOffset = getInitOffset()
+    if (props.autoplay) {
+      pauseLoop()
+      offset.value = targetOffset


autoplay变更只应该开启或者关闭定时器，不应该修改offset.value

hiyuki · 2024-12-23T11:08:31Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    props.bindchange && props.bindchange(eventData)
+  }
+
+  function getInitOffset () {


这个可以直接作为一个index=>offset的转换函数，getOffset(index)=>offset

hiyuki · 2024-12-23T11:19:37Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  })
+
+  useAnimatedReaction(() => step.value, (newIndex, preIndex) => {
+    const targetOffset = getInitOffset()


放在onLayout中，当用户没有在触碰操作时，更新offset.value

hiyuki · 2025-01-02T08:24:11Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+        renderChild = [lastChild].concat(renderChild).concat([firstChild])
+      }
+    }
+    const arrChilds = renderChild.map((child, index) => {


arrChildren

这个itemAnimatedStyle是不是可以在swiper-item内生成就可以

hiyuki · 2025-01-02T08:29:27Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+      const newChild = React.cloneElement(child, {
+        itemIndex: index,
+        customStyle: [itemAnimatedStyles, extraStyle],
+        key: 'page' + index


不需要自己去定义key，有可能会覆盖用户定义的key

hiyuki · 2025-01-02T08:35:35Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+
+  useAnimatedReaction(() => currentIndex.value, (newIndex, preIndex) => {
+    // 这里必须传递函数名, 直接写()=> {}形式会报 访问了未sharedValue信息
+    const isInit = !preIndex && newIndex === 0


isInit的的判断为啥需要newIndex === 0，用户可以直接传props定义非0的初始index吧

currentIndex基于props.current进行初始化

hiyuki · 2025-01-02T08:39:19Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+    }
+  }
+
+  function getOffset (index?: number) {


index参数改为必传吧

getOffset不需要是worklet

hiyuki · 2025-01-02T09:50:18Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  const step = useSharedValue(initStep)
+  const totalElements = useSharedValue(children.length)
+  // 记录选中元素的索引值
+  const currentIndex = useSharedValue(0)


基于props.current初始化

hiyuki · 2025-01-02T09:51:20Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  // 记录选中元素的索引值
+  const currentIndex = useSharedValue(0)
+  // 记录元素的偏移量
+  const offset = useSharedValue(0)


基于props.current调用getOffset进行初始化

hiyuki · 2025-01-02T09:52:26Z

packages/webpack-plugin/lib/runtime/components/react/mpx-swiper.tsx

+  }
+
+  function renderItems () {
+    const itemAnimatedStyles = useAnimatedStyle(() => {


这个可以直接在swiperItem中的useAnimatedStyle进行
