我写了一个测试导航的程序：

<view>

  <navigator url=’…/…/pages/i/first’ hover-class=‘navigator-hover’>ScrollView</navigator>

  <navigator url=’…/…/pages/swiper/sw’ hover-class=‘navigator-hover’>swiper</navigator>

</view>

app.json代码：

{

 “pages”:[

    “pages/navigate/navi”,

    “pages/i/first”,

    “pages/swiper/sw”

  ]

}

导航的第一个页面"pages/i/first",是一个测试scroll-view的页面，代码如下：

<view>

  <scroll-view

    scroll-y=“true”

    upper-threshold=“20”

    bindscrolltoupper=“scrolltoupperFun”

    lower-threshould=“30”

    bindscrolltolower=“scrolltolowerFun”

    scroll-into-view=’{{intoView}}’

    style=‘height:600rpx’

    >

    <view id=‘v1’ style=‘height:300rpx;text-align:center;background-color:cadetblue;’>

    这里是视图内容1

    </view>

    <view id=‘v2’ style=‘height:500rpx;text-align:center;background-color:darkkhaki;’>

    这里是视图内容2

    </view>

    <view id=‘v3’ style=‘height:600rpx;text-align:center;background-color:indianred;’>

    这里是视图内容3

    </view>

  </scroll-view>

  <button bindtap=‘scrollToV1’ >滚动到v1</button>

  <button bindtap=‘scrollToV2’ >滚动到v2</button>

  <button bindtap=‘scrollToV3’ >滚动到v3</button>

</view>

导航到该页面后，第一个按钮点击后事件处理程序不起反应，console提示：

Do not have scrollToV1 handler in current page: pages/i/first. Please make sure that scrollToV1 handler has been defined in pages/i/first, or pages/i/first has been added into app.json
t.warn @ WAService.js:9
N @ WAService.js:8
(anonymous) @ WAService.js:8
(anonymous) @ WAService.js:9
(anonymous) @ WAService.js:4
e.(anonymous function) @ WAService.js:4
d @ appservice:16
g.registerCallback @ appservice:16
k.forEach @ appservice:16
d @ appservice:16
h.onmessage @ appservice:16

但是，当把app.json改成：

{

 “pages”:[

    ”pages/i/first",

    “pages/navigate/navi”,

    “pages/swiper/sw”

  ]

}

后，即把它放到首页后，事件处理程序就正常了
