我在一个页面放置三个picker，选择第一个picker的时候，后边的bindchange事件也会跟着触发，见下图：
![]()
<view class="head">
<view class="picker">
<picker
bindchange="stylesChange"
value="{{stylesIndex}}"
range="{{styles}}">
<view class="weui-cell weui-cell_access">
<view class="weui-cell__bd">商品样式view>
<view class="weui-cell__ft weui-cell__ft_in-access">
{{styles[stylesIndex]}}
view>
view>
picker>
view>
<view class="picker">
<picker
bindchange="countChange"
value="{{countIndex}}"
range="{{count}}">
<view class="weui-cell weui-cell_access">
<view class="weui-cell__bd">显示个数view>
<view class="weui-cell__ft weui-cell__ft_in-access">
{{count[countIndex]}}
view>
view>
picker>
view>
<view class="picker">
<picker
bindchange="categoryChange"
value="{{categoryIndex}}"
range="{{category}}">
<view class="weui-cell weui-cell_access">
<view class="weui-cell__bd">商品列表view>
<view class="weui-cell__ft weui-cell__ft_in-access">
{{category[categoryIndex]}}

真机上有出现同样问题吗？
真机上试了一下，没有出现问题。
