VM309:1 Component "pages/a/a" does not have a method "a" to handle event "tap". 源代码如下：<view class="fl aside"> <view class="aside-item {{item.isActive ? 'active' : ''}}" wx:for="{{asideData}}" wx:key="index" data-active="{{item.isActive}}" data-index="{{index}}" bindtap="a">{{item.title}}</view>

源代码如下：{   "pages": [     "pages/a/a",     "pages/index/index",     "pages/b/b",     "pages/userConsole/userConsole",     "pages/storageConsole/storageConsole",     "pages/databaseGuide/databaseGuide",     "pages/addFunction/addFunction",     "pages/deployFunctions/deployFunctions",     "pages/chooseLib/chooseLib",     "pages/openapi/openapi",     "pages/openapi/serverapi/serverapi",     "pages/openapi/callback/callback",     "pages/openapi/cloudid/cloudid",     "pages/im/im",     "pages/im/room/room"   ],   "window": {     "backgroundColor": "#0000ff",     "backgroundTextStyle": "light",     "navigationBarBackgroundColor": "#ff0000",     "navigationBarTitleText": "南充市蜻蜓科技",     "navigationBarTextStyle": "black"   },   "tabBar": {     "color": "#0000ff",     "selectedColor": "#ffff00",     "backgroundColor": "#ffffff",     "borderStyle": "black",     "list": [{       "pagePath": "pages/b/b",       "text": "text",       "iconPath": "img/101.jpg",       "selectedIconPath": "img/105.jpg"     },     {       "pagePath": "pages/b/b",       "text": "text",       "iconPath": "img/102.jpg",       "selectedIconPath": "img/105.jpg"     },     {       "pagePath": "pages/b/b",       "text": "text",       "iconPath": "img/102.jpg",       "selectedIconPath": "img/105.jpg"     },     {       "pagePath": "pages/b/b",       "text": "text",       "iconPath": "img/102.jpg",       "selectedIconPath": "img/105.jpg"     }   ]   },   "sitemapLocation": "sitemap.json",   "style": "v2"   } [图片]
